Overview
Type 304 diamond plate, also known as tread plate or checkered plate, is a highly versatile and functional material. Its raised diamond pattern provides excellent slip resistance, making it a safety-oriented choice for walkways, stairs, and vehicle running boards. The base material, 304 stainless steel, is an austenitic alloy renowned for its outstanding resistance to rust and corrosion in a wide range of atmospheric and chemical environments.
This material combines functional durability with a bright, clean aesthetic. It possesses excellent welding characteristics, suitable for all standard fusion methods, and can be readily formed, bent, and fabricated. Its combination of strength, corrosion resistance, and non-porous surface also makes it a suitable choice for applications in food processing and chemical plants where both durability and hygiene are critical requirements for flooring and wall protection.

Applicable Standards
- ASTM A240: Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip for Pressure Vessels and for General Applications.
Common Applications
- Transportation: Truck beds, running boards, and trailer flooring - for durability and slip resistance.
- Industrial: Catwalks, work platforms, and trench covers - provides a safe, corrosion-resistant walking surface.
- Commercial Kitchens: Wall protection (wainscoting) and flooring - for hygiene, impact resistance, and easy cleaning.
- Architectural: Decorative panels, column wraps, and storefronts - for a modern, industrial aesthetic.
- Marine: Dock ramps and boat decking - leverages 304's good corrosion resistance in mild marine environments.
- Food & Beverage: Processing plant flooring and platforms - non-porous surface resists bacterial growth.
- Material Handling: Conveyor system surfaces and protective skirting - offers abrasion resistance.
- Residential: Workshop flooring, stair treads, and decorative kick plates - combines function with a clean look.
Working with Type 304 Diamond Plates
Machining
Grade 304 stainless steel has fair machinability but is prone to work hardening. Use sharp tooling, slow speeds, and heavy, constant feeds to prevent glazing. The use of a chip breaker is recommended to manage the tough, stringy chips produced during cutting.
Welding
Excellent weldability. Can be welded using all common fusion and resistance techniques, with or without filler metals. For heavy sections, post-weld annealing may be required to restore maximum corrosion resistance by dissolving any chromium carbide precipitation.
Finishing
The material comes with a standard mill finish and a raised diamond pattern. It can be cleaned and maintained easily. While not typically polished due to the textured surface, the base metal can be passivated to enhance corrosion resistance.

Frequently Asked Questions
Q: What is the difference between 304 and 316 stainless steel diamond plate?
A: 304 diamond plate offers excellent general-purpose corrosion resistance. 316 contains molybdenum, giving it superior resistance to chlorides and pitting, making it better for marine or chemical-heavy environments. For most architectural and industrial applications, 304 is sufficient.
Q: Can you cut 304 diamond plate to a custom size?
A: Yes, we offer custom cutting services for all our sheet and plate products, including 304 diamond plate. We can cut material to your specified dimensions for same-day pickup or delivery.
Q: Is 304 diamond plate magnetic?
A: No, in its annealed condition, 304 stainless steel is austenitic and therefore non-magnetic. However, it can become slightly magnetic after cold working or forming.
