Angle Steel (Angle Iron) is an L-shaped structural steel with two perpendicular arms, available in equal or unequal lengths. Made from carbon steel, it offers high strength, corrosion resistance, and durability. Commonly hot-rolled or cold-formed, it is widely used in construction (frames, brackets), machinery, bridges, and infrastructure. Its right-angle design ensures stability, while lightweight properties simplify installation. Surface treatments like galvanizing or painting enhance longevity.

Channel steel, or C-section steel, is a structural metal profile with a U-shaped cross-section featuring vertical legs and a flat base. Commonly made from carbon steel, stainless steel, or aluminum, it offers high load-bearing capacity and bending resistance. Produced via hot rolling or cold forming, it is widely used in construction (beams, frames), machinery (supports, brackets), and transportation (vehicle chassis). Its design enables easy welding, bolting, and installation, while standardized dimensions (e.g., ASTM A36, EN 10279) ensure compatibility. Galvanized or coated variants enhance corrosion resistance for outdoor or industrial applications.

H-Beam is an economical cross-section and high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of H-shaped steel are arranged at right angles, H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost saving and light structural weight, and has been widely used.
