Product Description

Galvanized Welded seamless square Steel Pipe details : 

Product Description

    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.
