Heavy Duty Steel Grating Plate Q235 ASTM A36
Available Sizes: 25×5mm, 30×3mm, 30×5mm, 40×5mm
Heavy duty steel grating is made by welding with heavy flat bar and cross/round bars with certain distances. Our steel grating features high strength, light structure, high load-bearing capacity, and convenient installation.
Steel grating undergoes hot dip galvanized processing, offering these advantages: material savings, reduced investment costs, easy installation, durability, lightweight structure, no dirt accumulation, excellent ventilation, lighting and heat dissipation properties, along with anti-corrosive and anti-acid/alkali corrosion resistance.

Applications
Steel grating can be widely used in petrochemical plants, water treatment facilities, sewage treatment plants, municipal engineering, environmental engineering and other fields for platforms, walkways, trestle bridges, ditch covers, ladder treads, fences and railings.
Banding
Heavy duty gratings are commonly subjected to shock and impact loads. We highly recommend that all open ends be banded. The welded band bar helps distribute impact loads and minimizes distortion when subjected to repetitive traffic patterns.
Serrated Surface
Optional serrated bearing bars enhance skid resistance. Consider this surface for applications subject to the accumulation of liquids or lubricants, or for inclined grating installations.
