When sourcing hot rolled structural steel profiles, dimensional tolerance is one of the most critical technical points. Tolerance defines the acceptable deviation from the nominal size, weight, straightness and shape of I-beam, H-beam, channel steel, angle steel and other sections. It directly affects fabrication, bolt fitting, welding and final structural safety. At Shandong Xinqiao Industrial

Steel is the backbone of global construction, infrastructure, machinery and manufacturing. The last two decades (2005–2025) have witnessed one of the most dramatic reshufflings of the global steel supply map. The balance of crude steel production has moved away from mature Western industrial economies toward fast-growing Asian markets, while new production hubs have emerged across

Heavy-Duty I Beam vs Light I Beam: How to Choose the Right I-Beam for Your Project I-beams are one of the most widely used hot-rolled structural steel profiles for building frames, support systems, platforms and engineering works. When sourcing steel beams, buyers often encounter two common terms: Light I Beam and Heavy-Duty I Beam. These

When buying structural steel such as H beams, angle steel, channel steel and flat bars, you will often encounter the term MTC (Mill Test Certificate) based on EN 10204 standard. Many buyers only ask for “an MTC” without specifying the certificate type, which leads to delays, inspection rejection or disputes at the port. EN 10204
