Aluminium Checker Plate - Tread Plate

Aluminium checker plate is made from alloys 5052 and 3003 and is commonly used for many varied products and projects including; transport industry including rail, marine, trailers, trucks, offshore and tool boxes, kick boards, shop fronts, ramps, roofing, flooring and architectural decorative uses. This type of plate differs to normal aluminium plate with mill finish due to its raised pattern. Whilst it is aesthetically pleasing and functional in many applications, care should be taken to ensure this product meets all the design requirements, including; spans, thickness/load limits, slip rating and environment considerations.

Welding: Aluminium checker plate / tread plate can easily be welded with 5356 filler wire
Please Note: Aluminium checker plate / tread plate is not referred to in Australian Standard AS1734 – Aluminium and Aluminium Alloys – Flat Sheet, Coiled Sheet and Plate. Typically most mills will recognise ASTM or GB specifications.

How is Aluminium Checker Plate made?

Aluminium tread plate is made by the semi-continuous casting, hot rolling and cold rolling of aluminium ingot. It is during the cold rolling operation where the checker or tread pattern is embossed onto one side of the coil during the final rolling operation. The rolls used to produce the pattern are expensive and made in unique sets. The height of the tread or lozenge is determined by the etching depth of the pattern into these finishing rolls.

Types of Aluminium tread plate

This type of plate comes in a range of patterns.

One bar pattern – also called Diamond or Propellor plate
Five bar pattern

What is the cost of Aluminium Checker Plate?

Due to the time and cost to make these special working rolls, and combined with the much slower rolling speeds that can be used, the price of tread plate attracts a premium over that of standard flat sheet or coil. This premium can be in the order of 15-20%. For current pricing of your specific requirements please email or call your local Austral Wright Metals Service Centre.

What alloy is checker plate made from?

In Australia, aluminium checker plate is most commonly stocked and sold in alloys 5052 and 3003. Alloy 5052 has good corrosion resistance and strength, and is sometimes referred to as “Marine Grade Aluminium”, and is used in the transport industry among many other applications. While alloy 3003 is commonly used for the manufacture of bright finishes with propeller or diamond shaped lozenges.
