Angle Steel is a simple L-shaped sectional profile, one of the most basic and versatile components in steel structures. It comes in equal leg and unequal leg types, featuring flexible installation, easy connection, and stable support. Our angle steel is widely used in building frames, towers, bridges, and machinery equipment manufacturing, providing reliable edge reinforcement and structural connections.

Suitable for single use or combination, adaptable to diverse scenarios.
Good torsional strength, stable for structural reinforcement.
Simple production process, economical for large-scale applications.
High Strength and Structural Reliability: The L-shaped cross-section provides excellent strength and stability, capable of bearing various vertical and lateral loads, making it an indispensable support member in trusses, transmission towers, and frame structures.
Excellent Connection and Easy Installation: Easily cut, drilled, welded, or riveted. Its right-angle geometry simplifies the connection and assembly with steel plates, other section steels, or concrete components, greatly simplifying the construction process.
Cost-Effectiveness and Material Efficiency: As a relatively lightweight yet high-strength structural material, its rational cross-section design efficiently disperses loads, achieving required load-bearing capacity with less steel, offering high economic viability for budget-conscious projects.
Wide Application Flexibility: Available in both equal-leg and unequal-leg types and various specifications. Widely used in mechanical manufacturing for brackets, equipment frames, and general construction for bracing and reinforcement.
Angle steel is hot rolled from billets heated to 1200–1250°C. The billet is passed through a series of grooves in a section mill, gradually forming the L-shaped cross-section. The process controls leg length, thickness, and toe radius. After rolling, the angle is cooled, straightened by stretching or rotary straightening, and cut to length. Both equal and unequal angles are produced.
Building Structures: Tower crane structures, industrial building roof trusses, bridge auxiliary members.
Supports & Reinforcement: Power transmission towers, communication towers, equipment supports, warehouse shelving.
Machinery Manufacturing: Machine bases, frames, stiffeners.
Everyday Applications: Furniture, guardrails, shelves.
