Rsj Beam
Introduction
An Rsj Beam stands for Rolled Steel Joist Beam. It is a type of structural steel beam commonly used in construction and engineering for supporting loads over long spans.
Feature
High-strength structural support
The Rsj Beam is made of S275JR or S355JR structural steel, with yield strengths of 275 MPa and 355 MPa respectively, and tensile strengths between 430-580 MPa.
Optimized cross-section design
The "I"-shaped cross-section of the I-beam gives it a higher moment of inertia (cross-section bending stiffness) in the vertical direction. Compared with ordinary H-beams, the web of this product is thinner but taller, and has stronger bending resistance at the same weight.
Excellent corrosion resistance
Our products are hot-rolled to form a dense oxide layer on the surface, and their corrosion resistance in a dry environment is better than that of ordinary carbon steel.

Application
Building Construction
Used as primary support beams in residential, commercial, and industrial buildings. They carry loads from walls, floors, and roofs.
Wall Openings and Lintels
Installed above doors, windows, or large wall openings to support the structure above without sagging or cracking.
Loft Conversions
Used to replace or strengthen existing joists during attic or loft renovations, providing enhanced load-bearing capacity.
Bridges and Walkways
Serve as core structural elements in small bridges and pedestrian walkways due to their high strength-to-weight ratio.
