Industrial Inquiries
Frequently Asked Questions
Common engineering and procurement answers regarding stainless steel grating specifications.
What are the primary differences between AISI 304 and AISI 316 stainless steel gratings?
AISI 304 (18/8 chromium-nickel alloy) provides excellent mechanical properties and rust resistance for general industrial, food processing, dairy, and beverage facilities. AISI 316 contains 2% to 3% molybdenum, which significantly enhances resistance to pitting and crevice corrosion in chloride environments, marine platforms, offshore installations, and chemical processing plants.
What surface finishes are applied to stainless steel bar gratings?
After assembly and welding, stainless steel gratings are chemically treated via acid washing and passivation to remove weld discoloration and heat tint. Electro-polishing is then performed to deliver a smooth, bright, and sterile surface that resists bacterial colonization and optimizes corrosion passivation.
Can stainless steel gratings be supplied with custom penetrations and bandings?
Yes. Panels are fabricated to engineering drawings with precision cut-outs for pipes, structural columns, and equipment penetrations. All external and internal edges are full-depth banded with flat bars to retain rated load capacities and eliminate trip hazards.
Which anti-slip surface profile is recommended for oily or wet areas?
For areas prone to oils, grease, chemical spills, or ocean spray, serrated bearing bars are recommended. Serrated profiles provide superior slip resistance compliant with international industrial safety codes without compromising load deflection limits.
What quality assurance documentation accompanies export shipments?
Every shipment includes EN 10204 Type 3.1 Mill Test Certificates verifying raw material chemical composition and mechanical strength, Positive Material Identification (PMI) inspection reports, dimensional check sheets, and passivation test records.
