products details
Ruicheng Steel is a professional manufacturer and exporter of Hot Rolled Steel I Beams. Our I-beams (also known as Universal Beams or I-Sections) are produced through advanced hot rolling processes, ensuring uniform grain structure and excellent mechanical properties.
Unlike H-beams, our I-beams feature tapered flanges, making them lighter yet incredibly strong in the vertical direction. They are widely used as cross-sections in construction where high vertical load support is required. We maintain a large inventory of common grades like Q235B and SS400 to ensure fast delivery for global projects.
