Galvanized C-shaped steel is a lightweight load-bearing structural steel made from cold-rolled or hot-rolled steel sheets such as Q235 through cold bending and roll forming, with a "C"-shaped cross section. The surface is hot-dip galvanized (zinc layer is usually 120–275g/㎡), and it has the characteristics of high strength, lightweight and corrosion resistance. It is widely used in purlins, wall beams, supports and mechanical components of steel structure buildings.

Galvanized U-shaped steel refers to steel with a U-shaped cross-section that has undergone hot-dip galvanizing or electro-galvanizing treatment. It combines the structural load-bearing capacity of U-shaped steel with the corrosion resistance of the galvanized layer. Based on the manufacturing process, it is mainly divided into two categories: cold-formed galvanized U-shaped steel (commonly used in light-duty construction/photovoltaic applications) and hot-rolled mining U-shaped steel (heavy-duty applications, mining support, less frequently galvanized).

Galvanized angle steel is a type of steel whose surface has been treated with zinc for corrosion protection, primarily used to prevent rust and extend its service life. It retains the original L-shaped structure of angle steel, but with an additional layer of zinc for protection. Depending on the processing method, it is divided into hot-dip galvanized and cold-dip galvanized types, and is widely used in power, construction, and transportation facilities.

Galvanized I-beams (also known as galvanized H-beams) are carbon structural steel sections (such as Q235B) with an "I"-shaped cross-section. They undergo a hot-dip galvanizing process to form a zinc alloy coating on the surface, making them a load-bearing structural material used to enhance corrosion resistance.

Galvanized H-beams are corrosion-resistant structural steel materials made by hot-dip galvanizing ordinary H-beams (hot-rolled or welded) to form a zinc protective layer. They have an "H"-shaped cross-section and combine high strength, lightweight, and corrosion resistance.
