Angle Bar
- Our hot rolled angle steels consist of equal and unequal angles, produced from premium carbon, alloy and stainless steel with precise tolerances and stable 90° L-shaped profiles. Equal angles with identical leg widths deliver balanced load capacity, while unequal angles suit asymmetric loads and special connecting applications. Surface options include black hot rolled, galvanized, pickled and polished finishes. Through rigorous rolling, straightening and comprehensive inspections, our angles achieve reliable straightness, flatness and mechanical properties. They are widely used in construction, machinery, transportation, solar brackets and global metal fabrication projects.
1. Equal Angle Steel
Certified
All equal angle steel is supplied with EN 10204 3.1 mill test certificates covering chemical composition, tensile, hardness and dimensional test. Comply with ASTM, EN, JIS, GB standards. Support SGS & BV third-party inspection, full heat number traceability for global metal buyers.
Application
Equal angle steel is standard L-shaped structural profile for construction, machinery and logistics industries. In building projects, it is widely used for solar mounting racks, factory wall keels, roof supports and warehouse storage frame reinforcements. Low carbon grades S235JR, A36 and SS400 own outstanding seismic performance for multi-story steel buildings. High strength Q355B equal angle fits heavy load workshop support frames. Mechanical factories process it into equipment bases and agricultural machinery brackets. Galvanized equal angle can resist rust for coastal outdoor projects. It can be cut, punched and welded on site for various engineering connection parts.

2. Unequal Angle Steel
Certified
All unequal angle steels are delivered with complete mill test reports including chemical composition, tensile strength, yield strength, elongation, hardness, flatness and dimensional inspection. They meet ASTM, EN, DIN, JIS and ISO standards. EN 10204 3.1 / 3.2 test reports and third-party inspection certificates can be provided upon request.
Application
Unequal angle steel is widely used in construction, machinery, transportation and metal fabrication. In building structures, it is used for asymmetric load supports, beam connections, column brackets, wall reinforcements and roof truss components, where one leg may require larger bearing area than the other.
In machinery manufacturing, unequal angles are suitable for equipment bases, conveyor brackets, machine frames and chassis reinforcements, offering balanced strength under non-uniform loading conditions. Galvanized unequal angle steels are commonly used for outdoor supports, solar mounting structures, fence frames and coastal engineering components.
Stainless steel unequal angles are applied in food processing equipment, pharmaceutical machinery, chemical equipment and offshore facilities, requiring good corrosion resistance and stable dimensional accuracy. They are also used in municipal engineering, transportation infrastructure and custom metal fabrication projects.
