Designed for cost-sensitive yet quality-focused projects, this Q235B angle steel delivers optimal cost-performance ratio, serving as a reliable structural material for industrial, construction, and fabrication applications worldwide.
Core Material: Q235B Carbon Structural Steel
Q235B is a premium variant of the classic Q235 general-purpose carbon structural steel grade, complying with GB/T 700 standards. The letter "Q" denotes yield strength, with 235 representing a minimum yield strength of 235 MPa, and the suffix "B" indicates that the material meets the requirement of room-temperature (20℃) impact toughness, distinguishing it from lower-grade Q235 variants. This grade features a well-balanced chemical composition with controlled carbon content (typically 0.12%-0.20%), ensuring superior ductility, toughness, and weldability, while maintaining adequate structural strength for light to medium-duty applications.
Compared to other Q235 grades, Q235B undergoes strict quality control during smelting and rolling, resulting in a uniform internal microstructure free from porosity, inclusions, and micro-cracks. This ensures consistent batch-to-batch mechanical performance, including a tensile strength range of 375-500 MPa, excellent cold formability, and compatibility with all standard welding, cutting, and bending processes. The B-grade impact toughness enhances the material's resistance to dynamic loads, reducing the risk of brittle fracture in structural applications, making it a more reliable choice than basic Q235 grades.
Production Process & Prime Quality Assurance
Our Q235B angle steel is manufactured via advanced hot-rolling technology, using high-purity continuous-cast steel billets that undergo rigorous raw material inspection to ensure purity and compliance with GB/T 700 standards. The production process involves multi-pass precision rolling at controlled high temperatures (above 1000℃), followed by controlled cooling and high-precision straightening to maintain perfect flatness, verticality, and dimensional consistency.
To guarantee prime quality, every batch of Q235B angle steel undergoes comprehensive quality testing, including chemical composition analysis, mechanical property verification (yield strength, tensile strength, impact toughness), and dimensional accuracy measurement. The finished product features a smooth, clean surface with minimal oxide scale, free from visible cracks, scratches, or mechanical damages, and a uniform cross-section throughout the entire length. This strict quality control ensures that the product meets the highest industrial standards for structural steel, delivering long-term reliability and performance.
