JIS 30A Rail
Product Overview
JIS 30A rail(also called JIS 30kg rail) is engineered to meet the rigorous standards of JIS E 1103-93 and JIS E 1101-93 (Japanese Industrial Standards), delivering exceptional durability for medium-to-heavy load applications. Constructed from Q235B carbon steel (equivalent to JIS SS400) or 55Q high-strength steel , it offers a balance of high tensile strength, weldability, and corrosion resistance, making it suitable for long-term use in harsh industrial and mining settings.
