English EnglishStainless steel bar grating is a premium corrosion-resistant flooring system fabricated from austenitic stainless steel alloys (AISI 304 or 316 grades) featuring 18% chromium and 8-10% nickel content that forms a self-healing passivation layer, delivering superior resistance to rust, chemical attack, and extreme temperatures ranging from -200°C to 400°C. Unlike carbon steel alternatives requiring galvanized coatings, our welded stainless steel grating achieves inherent corrosion protection through chromium oxide film formation, making it the preferred choice for food processing facilities, pharmaceutical cleanrooms, offshore marine platforms, and wastewater treatment plants where hygiene and longevity are critical.
Tianhe Grating manufactures custom stainless steel bar grating in three primary configurations. Welded stainless steel grating features bearing bars and cross bars fusion-welded using TIG (Tungsten Inert Gas) or plasma welding processes, ensuring sanitary crevice-free joints compliant with 3-A Sanitary Standards. Swaged stainless steel grating employs a mechanical interlocking method where cross bars are permanently swaged into pre-punched bearing bar slots, providing economical solutions for medium-duty applications. Serrated stainless steel grating incorporates notched bearing bar surfaces delivering exceptional anti-slip performance critical for wet environments such as pool decks and marine walkways.
Our heavy duty stainless steel grating utilizes ASTM A240-compliant materials:
304 Grade (18% Cr, 8% Ni): Ideal for food contact surfaces, freshwater applications, and mild chemical exposure
316 Grade (16% Cr, 10% Ni, 2% Mo): Superior chloride resistance for saltwater environments, pharmaceutical processing, and aggressive chemical handling
All stainless steel floor grating undergoes passivation treatment per ASTM A967 to maximize corrosion resistance, with optional electropolishing achieving Ra <0.15μm surface finish for cleanroom applications.
The self-repairing chromium oxide layer on our stainless steel walkway grating provides lifetime corrosion protection without coating degradation. ASTM B117 salt spray testing confirms our 316 grade stainless steel marine grating withstands 1000+ hours of continuous exposure without pitting corrosion, outperforming galvanized carbon steel by 400%. Surface finishes include 2B mill (Ra 0.5μm), BA bright annealed (Ra 0.2μm), and No.4 brushed options. Our products meet FDA 21 CFR 177.2600 for food contact, cGMP pharmaceutical standards, and EHEDG hygienic design guidelines.
Stainless steel drain grating and stainless steel gully grating feature open area ratios of 68-78%, ensuring efficient liquid drainage while supporting loads up to 10 kN/m² per EN 1433 standards.
Architectural stainless steel grating enhances modern building facades with mirror-polished or patterned finishes. Stainless steel stair tread grating with serrated surfaces ensures safety compliance in industrial stairwells. Stainless steel catwalk grating provides lightweight elevated walkways in power plants and refineries. Stainless steel swimming pool grating resists chlorine degradation while meeting ADA slip-resistance requirements. Food processing facilities utilize our stainless steel floor trap grating for HACCP-compliant drainage systems.
Installation utilizes stainless steel grating clips and stainless steel saddle clips manufactured from matching 304/316 alloys, preventing galvanic corrosion. Our engineering team provides stainless steel grating load table calculations and CAD drawings within 48 hours.
