Classification according to appearance dimensions: Galvanized metal u channel has various appearance dimensions, the common ones are C-shaped channel steel, U-shaped channel steel, L-shaped channel steel, etc. These different shapes of channel steel are suitable for different usage occasions and engineering needs.

Classification according to galvanizing method: There are two main galvanizing methods for galvanizing c channel metal: hot dip galvanizing and electro-galvanizing. Hot-dip galvanizing is to immerse steel in molten zinc liquid to cover the surface with a zinc layer, which has good anti-corrosion properties; electro-galvanizing is to form a zinc layer on the surface of steel through electrochemical methods, which is suitable for applications with higher requirements. surface finish.

Classification according to specifications: The specifications and dimensions of galvanized metal channels are usually classified according to length, width and thickness. Common specifications and sizes include 50*37*4.5, 63*40*4.8, 80*43*5, etc. Different specifications and sizes are suitable for different usage requirements and engineering needs.
