Plain Steel Bar Grating
Smooth-top welded bar grating. The most widely used industrial grating — cost-effective, easy to clean, available in carbon steel, stainless, and aluminum.
20–75mm bearing bars · 11–60mm pitch · GB/T 12755 / NAAMM MBG 531
Serrated Steel Bar Grating
Notched (serrated) top surface for anti-slip performance on wet, oily, or inclined surfaces. Mandated by OSHA and most offshore standards.
Same range as plain · I-series (NAAMM) · typically +5% cost
Hot-Dip Galvanized Grating
Carbon steel grating hot-dip galvanized to ISO 1461 / ASTM A123 for outdoor and corrosive environments. 45–85 μm zinc coating, 20–40 year life.
ISO 1461 / ASTM A123 / GB/T 13912 · +4% weight · 45–85 μm Zn
Stainless Steel Grating
SS 304 for general corrosion resistance. SS 316L for chloride environments, chemical plants, and food processing. Full range of bearing bar sizes.
Grade 304 / 316L · density 7.93–7.98 g/cm³ · electropolish option
Aluminum Bar Grating
Alloy 6061-T6 or 6063-T5 bar grating. ~34% the weight of carbon steel — ideal for structural load-limited platforms, marine, and architectural use.
6061-T6 / 6063-T5 · 2.70 g/cm³ · self-passivating
Grating Stair Treads
Pre-fabricated stair tread panels with perimeter frame, anti-slip serrated surface, and nosing options. OSHA 1910.23, NAAMM MBG 531, BS 4592.

Class A (pedestrian) to E (heavy highway) · frame systems available
Heavy Duty Steel Grating
Extra-heavy bearing bars (40×5mm to 75×6mm) for steel mills, mining, vehicle crossings, and industrial floors with extreme point loads.
40–75mm height · 5–6mm thickness · 22mm standard pitch
