Carbon steel angle steel is a long strip of steel with two sides perpendicular to each other. There are carbon steel equilateral angle steel and carbon steel unequal angle steel. The two sides of carbon steel unequal angle steel have different widths.

Carbon steel angle steel is a long strip of steel with two sides perpendicular to each other. There are equilateral carbon steel angle steel and unequal carbon steel angle steel. The two sides of the equilateral stainless steel angle steel are equal in width.

Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Hot-dip galvanized angle steel is a steel product that is processed by hot-dip galvanizing. Cold-dip galvanized angle steel has cold galvanized paint mainly with electrochemical principles to ensure full contact between zinc powder and steel, generating an electrode potential difference for anti-corrosion.

Galvanized unequal angle steel is a long strip of galvanized steel whose two sides do not share the same width. Galvanized unequal angle steel is divided into hot-dip galvanized unequal angle steel and cold-dip galvanized unequal angle steel.

The specifications of stainless steel angle steel are expressed in millimeters of side width x side width x side thickness. For example, "∠30×20×5" means an stainless steel unequal angle steel with side widths of 30 mm and 20mm, aside from a side thickness of 5 mm.
