Which thickness do you need?
Base-plate thickness — the raised five-bar pattern sits on top. Tap a thickness to see what it's built for.
Sheet weight calculator
Know the weight before it arrives — heavier sheets are pallet-delivered and may need offload assistance.
Calculated for grade 5754 aluminium (density 2.70 g/cm³) including the raised tread pattern. Weights are approximate.
How many sheets do I need?
Flooring, ramps or a trailer bed? We supply full sheets only (no cutting) — enter the area and we'll work out how many whole sheets it takes.
Based on your total area ÷ the sheet area, rounded up to whole sheets (we don't cut to size). Add a margin for offcuts and wastage — long or awkward shapes may need a little more.

Aluminium vs Steel chequer plate
Both grip well — the right choice depends on weight, corrosion and load.
| Feature | Aluminium 5754 | Steel Durbar S275 |
|---|---|---|
| Weight | Light — ~⅓ of steel | Heavy |
| Corrosion | Won't rust | Rusts unless painted/galv |
| Outdoor / marine | Ideal | Needs protection |
| Load-bearing strength | Good | Highest |
| Handling / install | Easy, one-person | Heavier lift |
| Best for | Trailers, vans, ramps, decorative | Industrial floors, ramps under heavy plant |
Common uses
Our aluminium chequer plate — also known as aluminium checker plate, checker plate sheet, aluminium tread plate or 5 bar treadplate — is supplied in 5754 grade with a raised five-bar tread pattern, in two sheet sizes: 8x4 (2500 x 1250mm) and 2m x 1m (2000 x 1000mm), available in 1.5mm to 6mm base thicknesses. Lightweight, corrosion-resistant and easy to fabricate, it suits trailer floors, vehicle lining, ramps, kick plates and decorative work, with a 3-5 working day lead time to mainland UK addresses.
Sizes Available
Choose your size and thickness above. Both sizes are supplied as full sheets (not cut to size), in 1.5mm, 2mm, 3mm, 4.5mm and 6mm:
8x4 (2500 x 1250mm) — the standard full checker plate sheet; the go-to size for trailer beds, ramps and flooring.
2m x 1m (2000 x 1000mm) — the compact size, ideal for smaller floors, steps, kick plates and jobs where a full 8x4 isn't needed.

Choosing the Right Thickness
Pick the thickness to match the job. 1.5mm and 2mm aluminium checker plate suit decorative panels, cladding and van linings; 3mm aluminium chequer plate is the popular all-rounder for medium-duty flooring and stair treads; 4.5mm handles heavy walkways and ramps; and 6mm aluminium checker plate is built for loading bays and high-load areas. The thickness quoted is the base sheet, measured beneath the raised five-bar tread plate pattern — the raised tread adds approximately 1.5mm on top, so total height is the base thickness plus around 1.5mm.
Common Uses
5754 aluminium chequer plate and tread plate is widely used for trailer and van floors, vehicle lining, toolboxes, loading ramps, stair treads, kick plates, wall and corner protection, workshop and garage flooring, shop fitting and decorative interior applications. Its low weight relative to steel makes it ideal where weight saving and corrosion resistance matter.
Aluminium Chequer Plate vs Steel Durbar Plate
Aluminium chequer plate (or checker plate) is significantly lighter than steel and naturally corrosion-resistant, making it the right choice for vehicle, marine, decorative and weight-sensitive applications. Mild steel durbar plate is stronger and heavier, better suited to heavy-duty structural flooring and high-traffic industrial use. Choose aluminium for weight saving and corrosion resistance, or steel durbar where load-bearing strength is the priority.
Cutting and Fabrication
Aluminium chequer plate can be cut, drilled, shaped and fabricated using standard metalworking tools. It is lighter and easier to handle than steel of equivalent size, and requires no protective coating for most applications thanks to its natural corrosion resistance.
