Hot-dip galvanized round pipe is a steel pipe used for anti-corrosion and enhancing the durability of materials. Its production process involves dipping the steel pipe into the molten zinc liquid to form a zinc layer covering the outer surface of the steel pipe, thus forming a layer of anti-corrosion zinc protective layer on the surface of the steel pipe

Annealed square pipe is a square steel pipe that has been heat treated (annealed) during the manufacturing process. The annealing process is usually to heat the steel pipe to a certain temperature and then slowly cool it to change the crystal structure of the steel, reduce hardness, improve toughness, and reduce internal stress.

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.
