Aluminium Chequer Plate: The Complete UK Guide

Aluminium chequer plate — also called aluminium checker plate, tread plate or 5 bar treadplate — is one of the most versatile sheet metals you can buy. This guide covers everything UK buyers ask: what the grades and thicknesses mean, how much a sheet weighs, what it costs, and which jobs it's right for, from trailer floors to ramps and stair treads.

What is aluminium chequer plate?

Chequer plate is aluminium sheet with a raised anti-slip pattern rolled into one face. In the UK the standard is the 5 bar (five-bar) tread plate pattern — repeating blocks of five short parallel bars set at alternating angles, which gives excellent grip underfoot and under wheels. “Chequer plate”, “checker plate” and “tread plate” all describe the same product; the spelling just varies by region. Our stock is grade 5754 aluminium, which is harder and stronger than plain 1050 sheet and naturally corrosion-resistant. We supply it in two full-sheet sizes — 8x4ft (2500 x 1250mm) and 2m x 1m (2000 x 1000mm).

Aluminium checker plate thickness guide

The thickness quoted is the base sheet, measured beneath the raised pattern. Choosing the right one comes down to load and handling:

• 1.5mm & 2mm aluminium checker plate — decorative panels, cladding, kick plates and van linings. Light and easy to cut.
• 3mm aluminium chequer plate — the popular all-rounder for medium-duty flooring, toolboxes and stair treads.
• 4.5mm — heavy walkways, gangways and ramps with regular traffic.
• 6mm aluminium checker plate — loading bays, plant access and high-load industrial areas.

Aluminium chequer plate weight per sheet

Weight matters for delivery and handling. As a guide, a full 2500 x 1250mm (8x4ft) sheet of 5754 chequer plate weighs roughly:

• 1.5mm — approx. 13.2 kg
• 2mm — approx. 17.6 kg
• 3mm — approx. 26.3 kg
• 4.5mm — approx. 39.5 kg
• 6mm — approx. 52.7 kg

A 2000 x 1000mm (2m x 1m) sheet weighs about 36% less than the equivalent 8x4. As a rule of thumb, 5754 aluminium tread plate weighs around 2.8 kg per m² per millimetre of thickness, including the raised pattern.

Checker plate for trailer floors and van linings

Aluminium is the go-to for vehicles because it's light and won't rust. 2mm checker plate is the usual choice for trailer floors and van linings — strong enough to take the knocks of loading without eating into your payload the way steel would. It also wipes clean and shrugs off road salt, making it ideal for year-round use.

Checker plate ramps and loading docks

For ramps, the raised five-bar pattern is what keeps wheels and feet from slipping in the wet. Step up to 4.5mm or 6mm for ramps that take trolleys, sack trucks or plant — the extra thickness resists flexing and denting under concentrated loads.

Checker plate stair treads and walkways

On stairs and raised walkways, 3mm chequer plate gives a slip-resistant surface that meets the practical demands of workshops, mezzanines and access platforms. It's light enough to fit without heavy lifting gear and needs no painting.

Decorative chequer plate: cladding and bar fronts

Beyond the practical, chequer plate has become a popular industrial-look finish for bar fronts, splashbacks, feature walls and kick plates. The 1.5mm and 2mm sheets are ideal here — light, easy to fix and full of character under warm lighting.

Aluminium vs steel chequer plate (durbar plate)

The two main options are aluminium chequer plate and steel durbar plate. Aluminium is roughly a third of the weight of steel and won't rust, so it wins for vehicles, marine use, decorative work and anywhere handling matters. Steel durbar plate is stronger and cheaper per sheet, making it the choice for heavy structural flooring and ramps under serious load. For a full breakdown, read our guide to steel vs aluminium. If you need maximum load-bearing strength, see our mild steel durbar checker plate.

How much does aluminium chequer plate cost?

Checker plate price depends on thickness and sheet size — thicker sheets use more metal, so they cost more. As a rough UK guide, an 8x4ft aluminium chequer plate sheet ranges from around £135 for 1.5mm up to roughly £490 for 6mm, with smaller 2m x 1m sheets costing less. Steel durbar plate is generally cheaper per sheet than aluminium of the same size. For current pricing, see the live product pages below.

Can you cut aluminium chequer plate to size?

Our sheets are supplied as full fixed sizes (2500 x 1250mm and 2000 x 1000mm) rather than cut to order. The good news is that 5754 aluminium cuts cleanly at home with a jigsaw or circular saw fitted with a non-ferrous blade, so you can trim it to your exact project on site.

Frequently Asked Questions

Is it “chequer plate” or “checker plate”?

Both spellings describe the same product. Aluminium chequer plate, checker plate, tread plate and 5 bar plate are interchangeable terms for aluminium sheet with a raised five-bar anti-slip pattern. Ours is supplied in marine-grade 5754 aluminium.

What thickness of aluminium checker plate should I choose?

Choose 1.5mm or 2mm for decorative panels, cladding and van linings, 3mm for medium-duty floors and stair treads, 4.5mm for heavy walkways and ramps, and 6mm for loading bays and high-load areas. The thickness quoted is the base sheet, beneath the raised five-bar tread.

How much does an aluminium chequer plate sheet weigh?

An 8x4ft (2500 x 1250mm) sheet weighs roughly 13.2 kg in 1.5mm up to about 52.7 kg in 6mm. A 2m x 1m sheet weighs around 36% less. As a rule of thumb, 5754 tread plate weighs about 2.8 kg per m² per millimetre of thickness.

What's the difference between aluminium chequer plate and steel durbar plate?

Aluminium chequer plate is about a third of the weight of steel durbar and won't rust, ideal for vehicles, marine and decorative use. Steel durbar is stronger and cheaper per sheet, better for heavy structural flooring. Choose aluminium for weight and corrosion resistance, steel for load-bearing strength.

Can I get aluminium checker plate cut to size?

We supply full fixed sheets (2500 x 1250mm and 2000 x 1000mm) rather than cut to order. Grade 5754 cuts cleanly with a jigsaw or circular saw and a non-ferrous blade, so it's easy to trim to size on site.

Will aluminium tread plate rust outdoors?

No. Grade 5754 aluminium tread plate is naturally corrosion-resistant and ideal for outdoor, coastal and marine use with no painting or galvanising required.
