SS400 is one of the most widely used structural steel grades defined in JIS G3101. Many fabricators pick this grade for general structural works and steel fabrication thanks to its well-rounded mechanical properties and excellent weldability.
SS400 channel steel works great for projects needing dependable structural support, straightforward on-site processing and economical material performance.
Suitable for general indoor applications, fabrication, and projects where additional corrosion protection is not required.
Suitable for outdoor structures, humid environments, agricultural facilities, and applications requiring enhanced corrosion resistance.
Primer, epoxy, or other customized coating systems can be provided according to project requirements.
For outdoor and corrosive environments, the appropriate protection system should be selected based on the actual service conditions.
