Pre-galvanized square tubing is usually made from cold or hot rolled steel sheets, which are then galvanized on the surface. Galvanizing is done by dipping the steel pipe into molten zinc to form a uniform zinc coating that provides protection against corrosion.

Hot-dip galvanized square tubing provides superior corrosion protection by coating the surface of the steel pipe with a zinc layer for long-lasting durability in harsh environmental conditions.

Annealed square pipe is a kind of square steel pipe after heat treatment. Through the process of high temperature heating and slow cooling, the grain of the square pipe is rearranged to achieve the purpose of eliminating internal stress and improving the hardness and plasticity of the material.
