PRODUCT DETAIL
Core steel structure products for factory construction
1. Main load-bearing structure (adaptable to tropical seismic requirements)
| Product Type | Specification Range | Core Function | Central America Adaptation Points |
|---|---|---|---|
| Portal Frame Beam | W12×30 ~ W16×45 (ASTM A572 Gr.50) | Main roof/wall load-bearing beam | Seismic joints use bolted flanges instead of welds, reducing weight and easing transport. |
| Steel Column | H300×300 ~ H500×500 (ASTM A36) | Supports frame and floor loads | Base plates hot-dip galvanized (≥85 μm) to resist humidity-induced corrosion. |
| Crane Beam | W24×76 ~ W30×99 (ASTM A572 Gr.60) | Supports industrial crane loads | End beams reinforced with shear plates for 5–20 ton cranes. |
2. Enclosure system products (weatherproof + anti-corrosion)
-
Roof Purlins: C12×20–C16×31 (hot-dip galvanized), spaced 1.5–2 m, suitable for color-coated steel sheet installation, with anti-typhoon capacity up to level 12.
-
Wall Purlins: Z10×20–Z14×26 (painted for corrosion resistance), with ventilation holes to minimize condensation in tropical factory conditions.
-
Support System: Bracing rods (Φ12–Φ16 hot-dip galvanized) and corner braces (L50×5 steel angles) improve lateral stiffness and ensure stability under hurricane-level winds.
3. Supporting auxiliary products (localized construction adaptation)
1.Composite Panels: Galvanized steel plates (10-20 mm) offer load-bearing capacity similar to that of standard foundation slabs in Central America within precast panel systems.
2.Connectors: Class 8.8 high strength galvanized bolts; no welding.
3.Coatings: Water-based intumescent paint (≥1.5 h) + UV protected anticorrosion acrylic paint with a durability of ≥10 years considering local environmental conditions.
