Commercial desk finishes: laminate, veneer, linoleum and powdercoat compared
Laminate, melamine, veneer, linoleum and powdercoat are classified under four different standards on four different scales, so the headline figures do not compare. Here is what each one publishes, where the published number stops being useful, and the six things a finishes schedule line needs to survive a tender.
Commercial desk finishes are not rated on one scale, which is why two tops that read identically on a schedule can be a decade apart in service. High pressure laminate is classified under EN 438: a horizontal general purpose grade, HGS or HGP, has to reach at least 150 revolutions for abrasion, while a vertical grade has to reach only 50. Melamine faced board is classified under EN 14322 and EN 14323 instead, where a decorative print is rated abrasion Class 1 and scratch resistance is at least 1.5 N. Forbo publishes its Furniture Linoleum at 2.0 mm and 2100 g/m2. Powder coatings in Australia are generally applied at 40 to 80 microns. Four materials, four standards, no common number.
That is the problem with a finishes schedule. Laminate, melamine, veneer, linoleum and powdercoat describe how a surface is made, not how hard it is, and the numbers that describe how hard it is come from standards that were never written to be compared with each other. What follows is what each publishes, and where the published figure stops being useful.
The four finishes, and the one number each is sold on
Every finish here has a headline figure a supplier will quote. Each is real. None is measured the same way.
| Finish | Classified under | The published headline figure | What it does not tell you |
|---|---|---|---|
| High pressure laminate (HPL) | EN 438 | Abrasion, initial point: HDS and HDP at least 350 revolutions, HGS and HGP at least 150, VGS and VGP at least 50 | Nothing about the substrate, which is what fails under a clamp |
| Compact laminate | EN 438-4 | CGS and CGF at least 150 revolutions | That the panel is self supporting, so it is not a like for like comparison |
| Melamine faced board (MFB, also low pressure melamine) | EN 14322 and EN 14323 | Abrasion Class 1 for prints, Class 3A or better for solid colours; scratch resistance greater than 1.5 N | A class is not a revolution count and will not convert |
| Timber veneer | AS/NZS 1859.3, tested to AS/NZS 4266.32 and 4266.33 | Bond strength and bond durability, pass or fail | Anything about the wear surface, which is the coating, not the timber |
| Furniture linoleum | EN and ISO methods per the manufacturer's data sheet | 2.0 mm total thickness, 2100 g/m2 total weight | Abrasion, which Forbo does not publish for the furniture grade |
| Thermoset powdercoat | AS 3715, and APAS specification AP-S0155 | Dry film thickness generally 40 to 80 microns | Whether an interior or an exterior grade was applied, which is a different product at the same thickness |
Read down the last column. In every case the published number describes one layer of an assembly, and the layer that fails on site is usually a different one.
High pressure laminate: the three letters are the specification
HPL is the most precisely specified of the group, and almost nobody uses the specification. A laminate is designated by three letters, and they carry more information than the colour name.
What H, G and S actually mean
Under EN 438-1 the first letter is the intended application, H for horizontal and V for vertical. The second letter is the duty, G for general purpose and D for heavy duty. The third letter is the type: S for standard, P for postforming, F for flame retardant. So HGS is a horizontal general purpose standard laminate and VGS is its vertical equivalent, and the difference between them is not cosmetic.
A vertical grade has to reach only 50 revolutions for abrasion against the horizontal grade's 150, and its scratch requirement on a smooth texture is rating 1 against rating 2. Vertical grades are thinner, cheaper and perfectly correct on a cupboard door or a screen face. On a work surface they are the wrong material, and because the printed decor can be identical, a VGS top and an HGS top can be indistinguishable at handover and obviously different eighteen months later.
The figures EN 438-2 actually publishes
A manufacturer's technical data sheet for a standard HPL range reports against the EN 438-2 clauses. The figures below come from one such published sheet, and they are the requirements for the grade, not a single batch result.
| Property, EN 438-2 clause | HGS and HGP, horizontal | VGS and VGP, vertical |
|---|---|---|
| Abrasion resistance, clause 10 | Initial point at least 150 revolutions | Initial point at least 50 revolutions |
| Resistance to scratching, clause 25 | Smooth at least 2, structured at least 3 | Smooth at least 1, structured at least 2 |
| Resistance to staining, clause 26 | Groups 1 and 2 at least 5, group 3 at least 4 | Same |
| Resistance to dry heat, clause 16 | Rating at least 4 | Rating at least 4 |
| Resistance to water vapour, clause 14 | Rating at least 4 | Rating at least 4 |
| Dimensional stability at high temperature and humidity, clause 17 | Not more than 0.55 per cent longitudinal, 1.05 per cent transverse | Not more than 0.75 per cent longitudinal, 1.25 per cent transverse |
| Light fastness, xenon arc, clause 27 | Greyscale rating better than 4 | Same |
| Nominal thickness and tolerance, clause 5 | 0.6, 0.8 and 0.9 mm, tolerance plus or minus 0.10 mm up to 1.0 mm | Same |
Two rows matter more than the rest on an Australian project. The dimensional stability figures are why a long top laid up in a cold factory and installed into a glazed north facing floor can move at the joint: the longitudinal and transverse figures differ, so a panel does not move evenly. The staining rows are graded by chemical group, which is why a laminate that shrugs off coffee can be marked by a whiteboard marker or a hand sanitiser.
Postforming is a radius, not a finish
The P in HGP means the sheet can be heated and wrapped around an edge. EN 438-2 clause 31 publishes formability as a multiple of the laminate thickness rather than as a fixed millimetre figure: for postforming grades the published requirement is Rd greater than 10 times the laminate thickness and Re greater than 20 times. The practical consequence is that a thin postforming laminate has a floor below which it will not wrap, and that floor scales with the sheet. A detail drawn with a 3 mm pencil round front edge is not a postformed edge, whatever the finish schedule says. It is an applied edge, a machined compact edge, or a solid timber lipping.
Melamine faced board: a different standard, and a scale that does not convert
Melamine faced board is a decorative paper impregnated with melamine resin and fused directly onto the particleboard or MDF core in one press. There is no separate laminate sheet, which is why it is lighter in the hand and thinner at the face, and why it is rated under a different standard.
| Property | Published figure | Note for a schedule |
|---|---|---|
| Abrasion resistance | Class 1 for decorative prints, Class 3A or better for solid colours | The woodgrain print is the lower rated option, not the higher one |
| Resistance to scratching | Greater than 1.5 N | Measured as a force, not as a revolution count |
| Resistance to staining | Class greater than 3 | A different scale again to the EN 438 group ratings |
| Resistance to cracking | Class greater than 3 | Relevant where a top is cut for a power module |
| Thickness tolerance | Plus or minus 0.3 mm up to 20 mm, plus or minus 0.5 mm above 20 mm | Matters where a 25 mm top meets a flush inset |
| Formaldehyde class | Class E1 to EN 13986, release not more than 3.5 mg per square metre per hour to EN ISO 12460-3 | The class belongs to the board and transfers to the finished top |
The honest conclusion from those two tables is the one most schedules avoid. A melamine Class 1 and a laminate 150 revolutions are not two points on one ruler, because EN 14323 and EN 438-2 are different test regimes with different specimens and different reporting. Anyone who says melamine is "about a third as hard" has done arithmetic on incompatible units. Where the comparison decides a specification, ask both suppliers for the test report, and accept that the answer may be that the two cannot be ranked on paper.
What can be said without a test report is structural. On melamine faced board the decorative layer is tens of microns thick and sits directly on the core, so a chip at an edge or a cut-out exposes the core immediately. On an HPL faced board there is a separate laminate sheet with its own thickness, between 0.6 and 0.9 mm on the figures above, and a chip has further to go before it reaches anything that swells. That is a materials argument, not a marketing one, and it is why the 25 mm melamine top is right for the Okidoki Table in a breakout and the laminate faced top is right where screens get clamped on and off.
Veneer: the bond fails before the timber does
Specifiers worry about the species and the cut. Fabricators worry about the glue line, and they are right. A decorative veneer on a commercial table is well under a millimetre of timber, so the question is never whether the oak is hard enough. It is whether it stays attached.
In Australia that question has a standards answer. AS/NZS 1859.3 covers decorative overlaid wood panels and includes wood veneers alongside low pressure melamine, PVC film and paper foils. The bond itself is tested under AS/NZS 4266.32 for veneer bond strength and AS/NZS 4266.33 for bond durability. AFRDI Standard 145 is the veneer industry test for both, and the Timber Veneer Association of Australia runs a voluntary quality assurance program against a method developed by Furntech at the University of Tasmania in July 2010, working to AS/NZS 4266.32: weights are added every 15 seconds until the veneer fails or all five masses have been added, totalling 15 kg, and the result is a simple pass or fail.
Two things follow. First, "veneer" with no further words on a schedule buys nothing: ask for a bond test result. Second, the wear surface is the coating, not the timber, so service life turns on the coating system and its repairability. That cuts both ways: a lacquered veneer top scratches more readily than an HGS laminate, and unlike laminate it can be sanded back and recoated in place.
Grain match is a sample stage decision, not a site decision
Where a veneer or timber look decor runs across more than one piece, the grain match gets argued about at handover. It is better argued at sample stage. Geneva publishes this plainly on the Sayla reception desk, where the feature hob is wrapped in a fluted board and the matching laminate is a separate element: colours are limited and the grain match is not guaranteed. That is the honest position for any wrapped profile meeting a flat sheet, because the two are made by different processes from different print runs.
Linoleum on a work surface: what Forbo actually publishes
Furniture linoleum is the quiet option here, and the one most often specified on feel rather than on data. What is published is narrower than the enthusiasm for it.
| Property | Published figure | Method cited |
|---|---|---|
| Total thickness | 2.0 mm | EN ISO 24346 |
| Total weight | 2100 g/m2 | EN ISO 23997 |
| Roll width and length | 1.83 m wide, approximately 30 m long | EN ISO 24341 |
| Light fastness | Rating 6 | EN ISO 105-B02, method 3 |
| Residual indentation | Approximately 0.20 mm | Published on the technical specification sheet |
| Gloss level | Below 5 | ISO 2813 |
| Flexibility | Diameter 50 mm | EN ISO 24344 |
| Chemical resistance | Resistant to diluted acids, oils, fats and conventional solvents. Not resistant to prolonged exposure to alkalis | EN ISO 26987 |
| Electrostatic propensity | Approximately 2.0 kV | EN 1815 |
| Heat resistance | 70 degrees Celsius | Published on the technical specification sheet |
| Reaction to fire, Australia | Group 3, average specific extinction area 47.7 m2/kg | AS 3837 |
Three of those rows change decisions. The alkali line catches cleaners: many commercial cleaning products are alkaline, and prolonged exposure is not what the material is rated for, so the cleaning regime has to be handed over with the furniture. The 2.0 mm thickness means linoleum is a surfacing material carried by a substrate, so every question in the substrate section below applies to it. The Group 3 classification is published against the Australian method, which is the number to have wherever a material group is assessed; our piece on where the absorption goes in an acoustic treatment covers how the permitted groups work by class of building.
The published composition is worth reading before specifying it into a heavy duty setting: flax seed oil, rosin binders, wood flour, limestone and dry pigments, calendered onto an impregnated paper backing with a water based cross linked acrylic finish. It is a natural material behaving like one, and the data sheet publishes a repair route no other finish here offers: cigarette burn marks can be removed with steel wool or a scouring pad.
Powdercoat: the standard everyone quotes is written for window frames
Powdercoat is the finish on the frame, the leg, the base and the locker, and the one most casually specified. The standard usually written into a schedule is AS 3715. Read its title: Metal finishing, thermoset powder coatings for architectural applications of aluminium and aluminium alloys. A steel table frame is not aluminium, so quoting AS 3715 alone against a steel frame is quoting a standard that was not written for the substrate.
The more useful Australian reference for furniture is the APAS specification for thermosetting powder coating, AP-S0155, published by CSIRO. It states that powder coatings are generally applied within a dry film thickness range of 40 to 80 microns, and splits the product into two grades: 0155/1 interior, where appearance matters more than corrosion resistance, and 0155/2 exterior. Its scratch resistance requirement, to AS/NZS 1580 method 403.1, is not less than 2 kg, and its adhesion requirement is a 6T bend with no cracking and no coating removal. Exterior durability is assessed by real exposure at an approved site for 24 months and seven years, not by an accelerated test.
Powder manufacturers publish against both families. Dulux states that its Duralloy range is formulated to meet AS 3715 and AAMA 2603, and publishes its warranty by application: for all projects, interior, general, 10 year durability and 10 year colour. It also publishes the limits, which are the part worth reading on a coastal Australian project: the coating is specified for pH 5 to 9 environments, only for coastal exposure more than 100 m from the high tide line, and not within 500 m of geothermal sources.
Specifier's note. The powder warranty and the furniture warranty are two different documents held by two different parties. A 10 year coating warranty from the powder manufacturer sits with the applicator who bought the powder and sprayed it to the stated film build. It is not a 10 year warranty on the table. If a frame finish matters enough to warrant, ask for the powder product name, the grade, the film thickness and the applicator's name at tender, and read them against the furniture warranty you are actually being offered. Our note on what a commercial furniture warranty covers and what the law already gives you sets out the difference between a warranty against defects and a consumer guarantee.
The substrate decides more than the finish does
Every finish above except compact laminate is a skin on a board, and the board is specified under its own standards: AS/NZS 1859.1 for particleboard, AS/NZS 1859.2 for dry process fibreboard, which is where MDF sits, and AS/NZS 1859.3 for the decorative overlay itself. The Australian industry guidance to those standards publishes typical densities of 600 to 700 kg/m3 for standard particleboard and roughly 650 to 850 kg/m3 for standard MDF depending on thickness class, with moisture resistant grades in a similar band. Formaldehyde emission for both is typically reported as class E1 by the desiccator method in the AS/NZS 4266 series, and E0 board is available from some manufacturers.
Two substrate decisions do more for a top's service life than any choice of decor.
The first is moisture resistance. Moisture resistant board is described in the industry guidance as suitable for areas of high relative humidity and occasional wetting, and explicitly not for continued wetting. A work surface with a sink nearby, a cafe bench, a pantry run or a top with a power cut-out that gets wiped daily is a candidate for moisture resistant board. Geneva publishes the Portland Meeting Table battens as E0 moisture resistant MDF with a decorative overlay on a steel core, which is the specification written out rather than implied.
The second is the balancing layer, and it produces most of the complaints. The Australian guidance is unambiguous: a compensating overlay should be applied to the opposite surface to balance the panel, and for veneered boards a balancing veneer must always be applied to the reverse side. The one common exception is high pressure laminate used on a single face, because the laminate's own rigidity assists stability. A melamine or veneer top faced on the show side only is a panel with unequal faces, and it will cup, almost always after installation in the building's own humidity, which is why it reads as a defect rather than as a specification error.
What is published on Geneva's tops
The quickest way to read this back onto a drawing is to look at what the published option list says on real products, from Geneva's table range and reception desks.
| Product | Published top options | Published frame or base finish |
|---|---|---|
| HALFMOON Table, Klaro Design | 25 mm laminate, melamine or veneer | 6 mm rolled mild steel legs, powder coated to Interpon or Dulux stocked colours |
| CONUS Meeting Table, Klaro Design | 4 mm steel, melamine or veneer | Rolled sheet steel base, solid American oak access tray lid |
| Okidoki Table, Thinking Works | 25 mm melamine, or 10 mm tempered glass on some models | Solid timber legs on a powder coated steel and aluminium frame |
| Rosie Laptop Table, Thinking Works | 25 mm HPL faced birch plywood, clear lacquered sharknose edge | Powder coated steel and aluminium base |
| Arki-Table, Pedrali | Solid laminate, composite marble, linoleum or gres | Steel trestle legs, extruded aluminium perimeter frame |
| Portland Meeting Table, Geneva | Up to 3600 by 1800 mm | E0 moisture resistant MDF battens with a decorative overlay over a steel core |
| Cone Meeting Table, Geneva | Meeting, pill, D end and round tops to 3000 mm | Black or white powder coat, or a laminated cone base |
| Sayla reception desk, Geneva | Matching laminate with a wrapped feature hob, 34 mm profile | Grain match across the hob and the laminate is not guaranteed |
Three patterns are visible. Laminate, melamine and veneer are usually alternatives on the same chassis, so the finish is a separate line item and will be chosen for you if it is left blank. Powdercoat is almost always the frame and almost never the top, so the top standard and the frame standard are different documents on the same drawing. And where a wrapped profile meets a flat sheet, the manufacturer who tells you the match is not guaranteed is doing you a favour.
For the dimensions that go with these finishes, meeting table sizes and what fits at the table and in the room carries the published lengths and seat counts, and reception desk heights and what 1100 mm actually means on a plan covers the counter. For the environmental claims that attach to these materials, which sustainability claims hold up on a schedule sets out what an EPD and an ecolabel each cover. The Thinking Works range carries the most published worktop data behind it.
What to put on the schedule
A finishes schedule line that will survive a tender reads like this: the material, the grade or class, the standard, the substrate, the balancing layer, and the edge. "Laminate, HGS to EN 438, on 25 mm E0 moisture resistant MDF, balanced to the reverse, 2 mm ABS edge" is a specification. "Laminate, white" is a hope.
Frequently asked
Is melamine the same thing as laminate?
No. Melamine faced board is a decorative paper fused directly onto a particleboard or MDF core and is classified under EN 14322 and EN 14323, where a decorative print is rated abrasion Class 1 and scratch resistance is at least 1.5 N. High pressure laminate is a separate sheet of resin impregnated papers pressed on its own and then bonded to a substrate, and it is classified under EN 438, where a horizontal general purpose grade has to reach at least 150 revolutions for abrasion.
Can I compare a laminate abrasion figure with a melamine abrasion class?
Not directly. The two materials are tested under different standards on different scales, so a melamine Class 1 and a laminate figure of 150 revolutions are not two points on one ruler. Where the comparison decides a specification, ask both suppliers for the test report rather than the headline figure.
Which finish takes the tightest edge radius?
Compact laminate, because the sheet is the whole panel and the edge is simply machined. A postforming laminate is limited by EN 438-2 clause 31, which publishes formability as a multiple of the laminate thickness, so a thin postforming sheet will not wrap a very tight nose. A solid timber lipping can be machined to almost any profile, but it introduces a second material that moves at a different rate to the panel.
Does a timber veneer top need a balancing veneer underneath?
Yes. The Australian Wood Panels Association guidance is explicit that a balancing veneer must always be applied to the reverse side, and that a decorative overlay needs a compensating overlay on the opposite face to balance the panel. A top veneered on one face only will cup, and it usually cups after installation rather than in the factory.
Is AS 3715 the right standard to quote for a powder coated steel frame?
Not on its own. AS 3715 is titled for thermoset powder coatings for architectural applications of aluminium and aluminium alloys, so it is written for aluminium rather than for a steel table or chair frame. For interior furniture the more useful questions are the dry film thickness, which in Australia is generally applied in the 40 to 80 micron range, and whether the coater is working to an interior grade or an exterior grade.
If you are working through a finishes schedule now and want the published grade, substrate and edge detail for a specific top rather than a general answer, send us the schedule line and we will come back with what the manufacturer publishes against it.
