Wall thicknesses are available from approximately 0.6 mm to 12 mm, depending on the pipe size, material grade and production method. Send us your required size and thickness for confirmation.
Pre-galvanized square pipe is formed from galvanized steel strip, while hot-dip galvanized pipe is galvanized after tube fabrication. Hot-dip galvanizing generally provides protection over the finished pipe surface. The suitable option depends on corrosion resistance requirements, application and project specification.
Zinc coating can be supplied in different ranges according to the galvanizing process and customer requirements. Common options are available up to approximately 275 g/m², with custom coating requirements confirmed before production.
Galvanized square steel pipes can be supplied according to ASTM A500, EN 10219, JIS G3466, GB/T 6728 and other requested standards. Common material grades include Q195, Q235, Q355, S235 and S355.
