Product Introduction
Galvanised H Beam
1. Product Definition & Manufacturing Process
Galvanised H Beam = hot‑rolled H beam (or welded H beam) + hot‑dip galvanized coating
Base H beam grades: Q235B, Q355B, SS400, ST37‑2, A36, S235JR
Galvanizing process: Immersed in molten zinc (approx. 450°C) after fabrication – forms a metallurgically bonded zinc‑iron alloy layer
Coating thickness per ASTM A123 / ISO 1461: average 50–100µm (local min. 40–85µm), providing 15–25 years of corrosion protection in normal atmospheres
2. Key Advantages & Performance Features
Long‑term corrosion resistance – Zinc layer sacrificially protects exposed steel edges and scratches; eliminates need for periodic painting
Excellent adhesion & uniformity – Coating does not flake during handling, cutting, or welding (touch‑up primer recommended at cut ends)
High strength with reduced weight – H beam shape provides superior load‑bearing capacity with less steel compared to solid sections
Easy on‑site handling – Pre‑galvanized beams arrive ready to install – no surface preparation required
Cost‑effective life cycle – Higher initial cost than uncoated steel, but lower total cost over 20+ years (no maintenance or repainting)
3. Common Use Scenarios & Applications
| Industry / Setting | Specific End Uses |
|---|---|
| Outdoor structures | Carports, canopies, pedestrian bridges, open‑sided warehouses |
| Coastal & marine | Dock supports, seawall reinforcement, jetty structures |
| Power & utilities | Transmission towers, substation frames, solar tracker mounting rows |
| Agricultural | Livestock sheds, grain storage buildings, greenhouse frames |
| Industrial platforms | Maintenance walkways, mezzanine floors, conveyor supports |
| Infrastructure | Highway sign gantries, noise barrier supports, railway platform roofs |
| Commercial buildings | Mezzanine floors in retail spaces, exposed architectural beams (industrial look) |
Typical span lengths: 6m, 9m, 12m – custom lengths cut‑to‑size before galvanizing to preserve coating integrity
4. Dimensional Range & Customisation Options
Size range: H100×100 to H900×300 (other sections available: welded H beams on request)
Web height: 100mm – 900mm | Flange width: 100mm – 300mm
Thickness: Web 6–16mm | Flange 8–28mm (depending on size)
Length: 5.8m / 6m / 9m / 12m or cut‑to‑length as required
Zinc coating thickness: 55µm, 85µm, 100µm average – specify based on exposure severity (C3 to C5 environment per ISO 9223)
Additional services:
Pre‑fabrication: Cutting, drilling, welding (before galvanizing)
Post‑galvanizing: End caps, touch‑up primer on cut ends, bundling for export
