Products Description
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
1.Material: ASTM A36 is a carbon steel material offering good strength and formability.
2.Corrosion Resistance: ASTM A36 steel can be galvanized or bitumen coated for enhanced resistance to rust and environmental factors.
3.Load Bearing: ASTM A36 grating is designed to support significant loads, suitable for applications in industrial platforms, walkways, and stair treads.
4.Customization: Grating can be smooth or serrated, customized in terms of bar spacing, thickness, and sizes to meet specific application.
