S235jr Angle Steel 100× 75× 6mm for Bridge Support

Our S235jr angle steel with the specific specification of 100×75×6mm (100mm main leg, 75mm secondary leg, 6mm thickness) is a high-performance structural component tailored exclusively for bridge support applications. Compliant with the European EN 10025-2 standard, S235jr is a premium low-carbon structural steel formulated with a precisely controlled chemical composition (C ≤0.24%, Mn ≤1.60%, Si ≤0.55%, P ≤0.045%, S ≤0.045%). This optimized formulation endows the angle steel with exceptional mechanical properties, structural stability, and durability, making it ideally suited to withstand the rigorous load and environmental conditions of bridge structures.

In terms of mechanical performance, S235jr 100×75×6mm angle steel exhibits characteristics specifically aligned with bridge support requirements. It boasts a minimum yield strength of 235 MPa and a tensile strength range of 360-510 MPa, ensuring robust load-bearing capacity to withstand static loads (bridge deck weight, traffic load) and dynamic stresses (vehicle impact, wind load). The grade features excellent ductility (minimum elongation of 21% in standard specimens) and toughness, particularly critical for absorbing energy during sudden load changes and resisting fatigue under long-term cyclic loads. Additionally, S235jr offers superior weldability, compatible with standard welding methods such as shielded metal arc welding (SMAW) and gas metal arc welding (GMAW), facilitating secure integration into bridge support frameworks.

The 100×75×6mm unequal-legged configuration is meticulously designed for bridge support applications, where asymmetric load distribution is common. The 100mm main leg provides enhanced load-bearing capacity for primary support, while the 75mm secondary leg ensures stable attachment to other bridge components (e.g., girders, piers). Manufactured via advanced hot-rolling technology (conducted at temperatures above 900°C, exceeding the steel's recrystallization point), the angle steel benefits from a refined grain structure that further improves toughness and impact resistance. The hot-rolling process also guarantees precise dimensional accuracy, consistent leg squareness, and uniform thickness-critical for ensuring tight fits and structural integrity in bridge assemblies. The 6mm thickness strikes an optimal balance between weight and strength, avoiding unnecessary structural bulk while maintaining reliable support performance.

As a dedicated solution for bridge support, this S235jr angle steel is widely used in the construction and reinforcement of highway bridges, railway bridges, and pedestrian bridges. Typical applications include bridge pier bracing, beam-end support brackets, deck framing reinforcement, and lateral stability components. Its low-carbon composition enables excellent compatibility with protective surface treatments such as hot-dip galvanization and epoxy coating, significantly enhancing corrosion resistance against moisture, rain, and deicing salts-common environmental hazards in bridge settings. Stringent quality assurance protocols are implemented throughout production, including chemical composition analysis, mechanical property testing (tensile, yield, elongation, and impact tests), dimensional inspection, and surface defect detection, ensuring full compliance with EN 10025-2 standards. For engineers and contractors seeking a reliable, application-specific steel component for bridge support, our S235jr 100×75×6mm angle steel delivers unmatched performance, durability, and structural safety.
