Products Description
Carbon steel grating is one of the most widely used industrial flooring and access solutions due to its excellent strength, durability, and cost-effectiveness. Manufactured from carbon steel bars through welding, pressing, or riveting processes, carbon steel grating provides a strong load-bearing surface while maintaining excellent ventilation, drainage, and slip resistance.
Compared with other materials such as aluminum or stainless steel, carbon steel grating offers higher mechanical strength and a more economical solution for heavy-duty industrial applications. It is commonly used in industrial platforms, walkways, stair treads, drainage covers, and equipment support structures.
As a professional steel product supplier, GNEE STEEL provides high-quality carbon steel grating with customized sizes, bearing bar dimensions, surface treatments, and packaging solutions to meet different project requirements worldwide.
Material: Grating made from ASTM A36 carbon steel is popularly used for operating gangway, walkways, and industrial flooring due to its high strength and load-bearing capabilities.
ASTM A36 is a U.S. standard specification set by ASTM International for a standard-grade structural carbon steel. It is one of the most commonly used steel grades in construction and engineering due to its good strength, ease of fabrication, and versatility.
ASTM A36 is used globally as an equivalent to other national standards, such as:
EN S275 in Europe
JIS SS400 in Japan
GB Q235 in China
Features of ASTM A36 Steel Grating:
Material: ASTM A36 is a carbon steel material offering good strength and formability.
Corrosion Resistance: ASTM A36 steel can be galvanized or bitumen coated for enhanced resistance to rust and environmental factors.
Load Bearing: ASTM A36 grating is designed to support significant loads, suitable for applications in industrial platforms, walkways, and stair treads.
Customization: Grating can be smooth or serrated, customized in terms of bar spacing, thickness, and sizes to meet specific application.
