Product Description
Galvanized Welded seamless square Steel Pipe details :
The galvanized square tube has good strength, toughness, plasticity and welding process performance, and has good ductility.
Its alloy layer is firmly attached to the steel base, so the hot-dip galvanized square pipe can be cold punched, rolled, and wire
drawn. , Bending and other shapes without damaging the coating, suitable for general processing such as drilling, cutting,welding,
cold bending and other processes. The surface of the square tube after hot-dip galvanizing is bright and beautiful.
