304 Stainless Steel Strip for Steel Grating

What is 304 Stainless Steel Strip for Steel Grating?

304 stainless steel strip is a commonly used material for manufacturing steel grating. Composed of 18% chromium and 8% nickel (known as 18-8 stainless steel), it provides excellent resistance to oxidation and chemical corrosion through the formation of a passive film. It features a minimum tensile strength of 75,000 psi and a minimum yield strength of 30,000 psi, offering a favorable strength-to-weight ratio. Typically supplied with a mill finish, it is also available with smooth or serrated surfaces to enhance slip resistance. Common spacing for bearing bars ranges from 25 to 40 mm, while cross bar spacing is typically 2" or 4".

304 vs. 304L Stainless Steel Strip: Steel Grating

304L is a low-carbon version. Since steel grating involves numerous welding processes, using 304L (or a 304/304L dual-standard material) can effectively prevent intergranular corrosion in the weld heat-affected zone, improving the durability of the weld joints.

 

Which Surface Finish Should Be Chosen for 304 Stainless Steel Grating, 2B or No.1?

No.1 (Hot Rolled & Pickled):The surface is relatively rough and non-reflective. Since the thickness is usually between 3mm and 6mm, No.1 is the mainstream choice for industrial stainless steel grating due to its lower cost.

2B (Cold Rolled):The surface is smooth and bright. It is suitable for architectural decoration, pedestrian walkways, or high-end commercial places where higher aesthetic requirements are needed.

 

Key Applications

Suitable for non-extreme corrosive environments, such as:
Industrial & Construction: Indoor or sheltered outdoor walkways, platforms, stair treads, and equipment maintenance access ways.
Municipal & Utilities: Drainage trench covers and wastewater treatment plants.
Food Processing: Used in clean environments where exposure to highly corrosive substances is not present.
