Heavy Duty Galvanized Welded Serrated Anti-Slip Trench Drain Gutter Cover Plate Industrial Floor Walkway Platform Steel Bar Grating
Product Overview
Heavy-Duty Welded Steel Grating is one of the most popular and cost-effective industrial flooring solutions worldwide. It is manufactured by electro-forge welding twisted square cross bars into high-strength carbon steel bearing bars under intense heat and pressure.
This advanced process creates a solid, one-piece permanently welded joint that delivers exceptional structural rigidity and high load-bearing capacity. Combined with a premium hot-dip galvanized surface treatment, our welded bar grating provides outstanding corrosion resistance, making it perfect for harsh environments.
As a versatile industrial flooring solution, this heavy-duty grating is widely utilized for walkways, catwalks, mezzanines, stair treads, and security fencing. It also serves as the ideal choice for heavy-vehicle ramps, warehouse docks, ventilation screens, suspended ceilings, wash racks, and all types of drainage trench pit covers.

Surface Treatment Options
We provide four finishes for anti-corrosion treatment of carbon steel bar grating:
Black / Bare Steel: No finish, life is very short, but the price is the cheapest.
Painted Coat: The anti-rust effect is general and can be any color.
Electro-galvanized: A small amount of zinc coating, easy to cause slight corrosion in humid environment.
Hot-dip galvanized: The most commonly used method to provide the best anti-rust effect, strictly in accordance with ASTM A123 or GB/T 13912-2002.
