lean and clean

Our unique process of creating "hollow-back" tread plate lugs allows us to start and finish with a cleaner product that is also 16%-18% lighter than conventional flat-back tread plate.

A clean tread plate requires less preparation for finishing and can help achieve a better, longer lasting finish keeping the components in sustainable service longer.

The weight reduction means you start with less material resources, and in transportation applications, this weight reduction saves energy in everyday use.


light weight tread plate

Most notable of the Rigidized® Metals product is the hollow-back produced while rolling the sheet steel on a synchronized set of rolls. The embossed metals pattern on the bottom roll meshes with the top roll to create a raised pattern or "lug" on the top side of the steel sheet, while an indentation is created on the underside in the same shape as the pattern lug.

The use of standard sheet gauges allows the metal to move into place to create the lug, but does not add weight to the piece. In a comparison to the standard stainless steel, carbon steel or aluminum "flat-back" tread plate products of the same thickness, the Rigidized® Metals Tread Plate product is consistently 16% to 18% lighter than its competitors.


start with the finish

Rigidized® Metals tread plates can be made from any metal sheet, including any grade of stainless steel, any aluminum alloy and zinc-coated metal (galvanized or galvanneal carbon steel). Rigidized® Metals can produce all of these metals in four different tread patterns to appeal to any application. Truck body and trailer manufacturers have a choice in specifying a tread plate product that fits every metal requirement.

One of the most significant benefits of the Rigidized® Metals' deep-texturing process is its ability to produce tread plate patterns in a wide range of thicknesses. Similarly, the constant challenge to any truck body manufacturer, these days, is to reduce the overall weight of each unit. This is another major reason to choose Rigidized® Metals tread plate. While the term "tread plate"often suggests a heavy decking plate, usually 3/16" or 1/4" thick with a solid back, Rigidized® Metals offers a thickness range of .018" to .125" in stainless steel. All types of metal can be rolled up to 60" wide. The availability of lighter gauges allows these patterns to be used in decorative, but still functional, areas, such as door liners, toolboxes and covers. One-side bright aluminum is available in sheet and coil up to 48" wide from .025" to .062" thick.
