Product Description

Type of stainless steel Diamond plate

stainless steel floor plate, also known as “tread plate” or “diamond plate”, is an excellent candidate for most processing techniques as well as both indoor and outdoor applications. This product has a textured dull grey finish with a raised diamond pattern to provide all around traction. Stainless steel floor plate has a hot rolled, annealed and pickled (HRAP) finished surface. Its high strength properties and excellent corrosion resistance make it the perfect candidate for catwalks, trench covers, walkways, and ornamental projects. ASTM A793 is the standard specification for stainless steel rolled floor plate.

Advantages of Stainless Steel Checkered Sheet

1. Excellent Corrosion Resistance

The checked plate made of stainless steel is more resistant than ordinary carbon and galvanized steel sheets. Besides, the Cr element in stainless steel improves the atmospheric corrosion resistance, especially in chloride and alkaline corrosion.

2. Great Anti-slipping Performance

One of the biggest characteristics of stainless steel checker plate is that it has good anti-skid features due to concave and convex patterns. This can provide all-around traction and make it very practical.

3. High Workability

The plate is easy to weld, cut, form and machine with proper equipment. In addition, this processing procedure does not damage its mechanical properties.

4. Attractive Finish

It has high-quality modern appearance and strong metallic texture. The silver-grey finish and raised diamond pattern make it more attractive and decorative. Besides, it has many different patterns to choose from to meet different application needs.

Additional steel processing services

cutting Service

For parts that require extremely high wear resistance, we use abrasive waterjet cutting to maintain hardness throughout the part without creating a heat-affected zone. For thicker plates up to 200mm, we use precisely controlled CNC oxy-fuel cutting. For products requiring high cut quality and dimensional tolerances, we use high-definition underwater plasma cutting to maximize plate performance in abrasive applications.

frequently asked questions

Is diamond plate stainless steel?

How Is SS Checker Plate Made?

Diamond plate is typically made of metal. The most popular types of metal used for diamond plate are aluminum, steel and stainless steel. In addition to diamond plated metal, plastic can also be used to create interlocking diamond plate sheets.

There are two different production processes. A kind of stainless steel checker plate is rolled by the rolling mill when producing stainless steel. The thickness is about 3-6mm, and it is annealed and pickled after hot rolling. The process is as follows:
Stainless steel billet → Hot rolling → Hot annealing and pickling line → Leveling machine, tension leveller, polishing line → Cross-cutting line → Hot-rolled stainless steel checkered plate.

This kind of checker plate is flat on one side and patterned on the other. It is more commonly used in the chemical industry, railway vehicles, platforms and other applications where strength is required.

The other kind of stainless steel diamond plate is made of hot-rolled or cold-rolled stainless steel by mechanical stamping. These products are concave on one side and convex on the other side. They are often used for decoration purposes.
