DTC Углеродистая сталь H‑Beam | Q235B Q355B Структурная сталь I-Beam

Product Overview

DTC carbon steel H‑beam is a hot ‑ rolled structural steel profile with an H‑shaped cross‑ section, manufactured from Q235B or Q355B carbon steel. The parallel flange and web structure delivers excellent load ‑ bearing capacity in both vertical and horizontal directions. Our H‑beams are widely used in building frames, warehouse construction, bridge supports, industrial plants and various steel structure engineering projects.

Core Product Advantages

• High Load‑ Bearing CapacityH‑shaped section provides strong bending resistance and structural stability
• Parallel Flange Design: Uniform flange thickness for easy connection and welding fabrication
• Cost-Effective Structure: Higher strength ‑t‑ weight ratio compared with traditional I‑beams
• Multiple Material GradesQ235B for general structures, Q355B for high ‑strength heavy ‑load applications
• Easy Fabrication: Standard dimensions simplify cutting, welding and on ‑ site assembly
• Wide Size Range: Various web heights and flange widths to meet different design requirements

Available Steel Grades

• Q235B carbon steel – standard structural grade
• Q355B low ‑ alloy steel – high ‑strength heavy ‑load grade
• SS400, A36 equivalent grades for export projects
