The steel 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
