The Equal Carbon Angle Steel St37 Gi Angle Bar Profile S235jr 100X100 is a high-quality structural component engineered for versatility and durability, integrating premium carbon steel materials, standardized equal-leg design, and hot-dip galvanizing (Gi) treatment. Specifically crafted to meet the rigorous demands of construction, industrial, and infrastructure projects, this angle steel combines excellent mechanical properties, corrosion resistance, and precise dimensional accuracy, serving as a reliable load-bearing and connecting solution for diverse applications.
This angle steel offers two high-performance carbon steel material options-St37 and S235jr-both renowned for their superior ductility, weldability, and cost-effectiveness in structural applications. St37, a widely used German DIN standard mild carbon steel, features a minimum yield strength of 235 MPa and a tensile strength ranging from 340 to 470 MPa, characterized by excellent formability and toughness, making it ideal for light to medium-duty structural roles. S235jr, a European EN standard mild carbon steel, shares comparable mechanical properties with St37 (minimum yield strength 235 MPa, tensile strength 360-510 MPa) and is recognized for its consistent quality and compatibility with international construction standards, ensuring seamless integration into global projects.
A defining feature of this product is its hot-dip galvanizing (Gi) treatment, a premium anti-corrosion process that significantly extends its service life. During the Gi process, the angle steel is fully immersed in molten zinc, forming a dense, uniform zinc coating that acts as a robust barrier against moisture, chemicals, and environmental erosion. This coating not only enhances the product's resistance to rust and corrosion in harsh outdoor, humid, or industrial environments but also maintains its structural integrity over long-term use, reducing maintenance costs and ensuring durability in diverse working conditions.
The product adheres to a standardized equal-leg design with a key specification of 100X100mm, meaning both legs of the L-shaped cross-section measure 100mm in length, with precise thickness and dimensional tolerances strictly controlled through advanced rolling and precision cutting technologies. The equal-leg structure ensures balanced force transmission, enabling the angle steel to evenly distribute loads across the entire structural system, thereby enhancing stability and load-bearing capacity. This 100X100mm standard size is widely recognized in the industry, offering seamless compatibility with other structural components and facilitating efficient on-site installation.
As a carbon steel angle bar profile, this product inherits the inherent advantages of mild carbon steel, including excellent weldability, formability, and machinability. It can be easily cut, welded, bent, and drilled according to on-site project requirements, providing flexibility in structural design and construction. The uniform cross-sectional structure and precise dimensions ensure consistent performance across each piece, eliminating installation errors and improving construction efficiency.
Strict quality control measures are implemented throughout the entire production process to ensure product excellence. From raw material procurement-where St37 and S235jr steel billets are rigorously inspected for chemical composition and mechanical properties-to rolling, galvanizing, and finished product testing, every step adheres to international quality standards. Each batch of angle steel is accompanied by a detailed quality inspection report, verifying dimensional accuracy, coating thickness, and mechanical performance, ensuring compliance with project specifications and industry regulations.
Widely applied in construction and industrial projects worldwide, the 100X100mm Equal Carbon Gi Angle Steel St37/S235jr serves as a core structural component in commercial buildings, residential complexes, industrial workshops, bridges, railings, and municipal infrastructure. Its combination of premium materials, hot-dip galvanizing protection, standardized equal-leg design, and reliable performance makes it a preferred choice for engineers, contractors, and project managers seeking a cost-effective, durable, and versatile structural solution for their projects.
