STK400 Galvanized Steel Pipe
STK400 Galvanized Steel Pipe is a mainstream hot-dip galvanized steel pipe complying with Japanese JIS standards, made of high-quality carbon structural steel. Its dense zinc coating formed by hot-dip process offers excellent atmospheric corrosion and rust resistance with strong adhesion. The pipe features reliable tensile and compressive strength, superior weldability, formability and precise dimensional tolerance, with easy on-site cutting and installation. Complete in specifications for customized processing, it’s a cost-effective anti-corrosion steel pipe for general structural and low-medium pressure fluid transmission applications.
