Steel Structure Components — The Building Blocks, Fabricated Right
Every steel structure — from a workshop to a bridge to a stadium — is made from components. Most suppliers cut and weld them by hand. We use CAD-CAM intelligent production lines where design data drives CNC equipment directly. The difference shows up on site: components that fit, joints that align, bolts that go in without a sledgehammer.
A Structure Is Only as Precise as Its Least Precise Component
In steel structure construction, field problems almost always trace back to component fabrication: a beam that is 3mm too long, a bolt hole that is 2mm off-center, a weld that was laid by a different welder than the one who qualified the procedure. These are not catastrophic individually. But on a 500-ton steel structure, they compound — misalignment cascades through connections, and by the time the roof goes on, tolerances have been eaten up.
Our CAD-CAM production lines eliminate this risk. The structural design model — the same model that the engineer analyzed — is exported directly to CNC cutting machines, drilling lines and robotic welding stations. There is no "interpretation" step where a foreman reads a drawing and sets up a machine. The digital model IS the production instruction.
What We Manufacture
H-Beams & Tapered Beams
Welded H-beams (custom section, not standard mill sections) and tapered portal-frame beams. Fabricated on our automatic H-beam welding line — web-to-flange welding with submerged arc, automatic straightening, and CNC flange straightening.
- Section height: 200-1500mm
- Web thickness: 4-32mm
- Flange width: 100-500mm
- Length: up to 16m (longer by splice)
- Steel grade: Q235B, Q355B, Q390B, Q420B
Rectangular hollow section columns fabricated from four plates, including our proprietary cross-to-box column design for high-rise seismic structures. Internal diaphragms, stiffeners and base plates all integrated in-shop.
- Section: 200x200 - 1000x1000mm
- Plate thickness: 6-50mm
- Internal diaphragm welding
- Seismic detailing per GB 50011
Insulated Sandwich Panels
Continuous production line for insulated wall and roof sandwich panels. PU/PIR, EPS or mineral wool core between pre-painted steel skins. Used for our industrial building envelope systems.
- Core: PU/PIR, EPS, Rockwool
- Skin: 0.4-0.6mm pre-painted steel
- Thickness: 50-200mm
- Thermal: 0.22-0.42 W/m2K
- Fire: Class A (rockwool)
Corrugated Web Beams
Beams with corrugated (sinusoidal) webs instead of flat plates — higher shear resistance per unit of steel, no need for intermediate stiffeners, and an aesthetic that architects appreciate for exposed structures.
- Corrugation: sinusoidal/trapezoidal
- Web height: 300-1500mm
- Wave: 155-280mm wavelength
- Shear: 30-50% higher than flat web
Purlins, Bracing & Accessories
C-channel and Z-purlins (cold-rolled), tie rods, cross bracing, sag rods, base angles, eave struts, ridge flashing, gutter systems. Everything needed to complete the structure beyond primary members.
- Purlin: C/Z sections, 80-300mm
- Bracing: round bar, flat bar, angle
- Gutter: coated steel, 0.6-1.2mm
- Fasteners: high-strength bolts Specs
Surface Treatment & Coating
Shot blasting (Sa 2.5) to bare metal, followed by epoxy primer + polyurethane topcoat. For corrosive environments: hot-dip galvanizing (60-120 microns zinc) or zinc-rich primer + epoxy + PU system. Coating thickness verified per project spec.
- Blast: Sa 2.5 (ISO 8501-1)
- Paint: 2-4 coat epoxy/PU system
- Galvanize: 60-120 microns zinc
- DFT: 120-280 microns (per spec)
