Our L-shaped steel angle steel is a versatile structural solution, ideally suited for beam bridges and transmission towers. Crafted with high-strength materials, it delivers exceptional load-bearing capacity and structural stability, ensuring reliability in critical infrastructure projects. The L-shaped design offers optimal rigidity and easy integration, facilitating secure connections in complex frameworks. With excellent weldability and durability, it withstands harsh environmental conditions, from heavy loads on bridges to extreme weather at transmission tower heights. Its consistent dimensions and robust performance make it a trusted choice for enhancing the safety and longevity of beam bridges and transmission towers.
Typically made of Q235B/Q355B low-alloy high-strength steel (compliant with GB/T 706-2016/GB/T 1591-2018), it delivers:
Excellent load-bearing capacity: Q235B has a yield strength ≥235 MPa and tensile strength 375-500 MPa; Q355B offers yield strength ≥355 MPa and tensile strength 470-630 MPa. This enables it to bear static loads (e.g., beam bridge deck weights, transmission tower self-weight) and dynamic loads (e.g., vehicle impact on bridges, wind-induced vibration on towers).
Superior ductility & fatigue resistance: Elongation ≥21% (Q235B) and ≥22% (Q355B) allow elastic deformation under sudden loads (e.g., earthquakes, strong winds) without brittle fracture. For transmission towers (exposed to cyclic wind loads year-round) and beam bridges (subject to repeated vehicle passes), this fatigue resistance prevents crack propagation and extends service life to 30-50 years.
Weather & corrosion compatibility: When paired with anti-corrosion treatments (see Section III), Q235B/Q355B angle steel resists humidity, industrial fumes (for urban bridges), and salt spray (for coastal transmission towers).
Distributes stress evenly: The two legs of the angle steel (e.g., 50×50×5mm, 100×100×10mm) act as dual load paths, transferring vertical/horizontal forces to the foundation or main structure. For example, in beam bridges, angle steel used as "beam web reinforcement" distributes bending stress from the deck to the main beam, avoiding localized overloading.
Maximizes space utilization: The compact L-shape fits into narrow structural gaps—critical for transmission towers (where multiple components converge at joints) and beam bridge piers (with limited space for reinforcement). Unlike bulky H-beams, angle steel adds strength without occupying excessive space.
Enhances structural rigidity: When welded or bolted to other components (e.g., bridge girders, tower trusses), the right-angle design forms a "triangular stable structure" (a basic principle of truss engineering), reducing lateral deformation (e.g., preventing transmission towers from leaning in strong winds, or beam bridges from twisting under uneven loads).
