Other fields: such as furniture, transportation facilities, sports equipment, etc.

Material: Galvanized steel pipes are generally made of low-carbon steel such as Q195, Q215, and Q235.
Specifications: The specifications of galvanized steel pipes are usually expressed by outer diameter and wall thickness. Common specifications include DN15-DN600, etc.
Galvanizing process: The galvanizing process is mainly divided into hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing is to immerse the steel pipe in molten zinc liquid to form a zinc-iron alloy layer and a pure zinc layer on the surface of the steel pipe; electro-galvanizing is to use the principle of electrolysis to deposit a layer of zinc on the surface of the steel pipe.
Galvanized layer thickness: The galvanized layer thickness is an important indicator to measure the quality of galvanized steel pipes, usually expressed by the weight of the zinc layer (g/m?). The national standard has clear provisions on the thickness of the galvanized layer.
Surface quality: The surface of the galvanized steel pipe should be smooth and flat, without defects such as cracks, bubbles, and inclusions.
