Round Steel Beam is a cylindrical structural steel member used as a load-bearing or transfer element in steel structures, typically applied in truss systems, support frames, pipe structures, and industrial equipment frameworks.
Key Features
High Load Resistance
Made from Q235B / Q355B steel (≥235 / 355 MPa), allowing the member to carry tensile and compressive loads without deformation.
Uniform Stress Distribution
Circular cross-section distributes load evenly along the axis, reducing local stress concentration compared to flat sections.
Flexible Connection Options
Can be connected by welding, end plates, or threaded joints depending on structural requirements.
Multi-Layer Corrosion Protection
Shot blasting + primer + topcoat (≥120 μm) or galvanizing reduces rust in outdoor and industrial environments.
