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) | Roof and wall main load-bearing beam | Seismic-resistant bolted joints, optimized cross-section for lighter weight and easier transport |
| Steel Column | H300×300 ~ H500×500 (ASTM A36) | Supports frame and floors | Embedded seismic connectors, hot-dip galvanized (zinc ≥85μm) to resist humid conditions |
| Crane Beam | W24×76 ~ W30×99 (ASTM A572 Gr.60) | Industrial crane load-bearing beam | High-load capacity (for 5–20t cranes), end beams with shear-resistant connection plates |
2. Enclosure system products (weatherproof + anti-corrosion)
Roof Purlins: C12×20 to C16×31, hot-dip galvanized, with a spacing of 1.5–2 m. Suitable for color-coated steel panels and typhoon resistance up to level 12.
Wall Purlins: Z10×20 to Z14×26 with anti-corrosion paint and has ventilation holes to prevent moisture build up in tropical factory conditions.
Support System: Hot dipped galvanized round steel Φ12–Φ16 and corner braces (L50×5 steel angle) for bracing enhance the sideways stability against the force of hurricane winds).
3. Supporting auxiliary products (localized construction adaptation)
Embedded components: Hot-dip galvanized steel plates (10–20 mm thickness) for concrete foundations, popular in Costa Rica and others in Central America.
Bolts: On site welding is replaced by high-strength bolts (Grade 8.8, hot-dip galvanized) which cuts down on the construction time.
Fire & Corrosion Protection: Water-based intumescent coating (≥1.5 h fire resistance) and UV-resistant acrylic anti-corrosive coating (≥10 years service life), complying with local environmental regulations.

PACKAGING AND SHIPPING
Packaging:
The steel is compressed to shield the surface and maintain stiffness in the processing and shipping. Products are usually packaged in waterproof wrapping, plastic or rust-proof paper, and small accessories are packed in wooden box. Each panel or pack has clear labeling for safe and efficient off-loading and for an easy installation on site.
Transportation:
The steel building supplies are transported by container or bulk carrier based on size and destination. Heavy or oversized pieces are strapped with steel and braced with wood to prevent shifting or bowing in transit. Every consignment conforms to international transport standards offering prompt delivery and safe handling for distance/labor and over sea transport.

FAQ
Q: What standards do your steelwork comply with?
A: Our steel is to American standards for example ASTM A36, A572, A588. A36 is a plain carbon steel with good formability and weldability, whereas A588 is a weather friendly steel suitable for corrosive atmospheres.
Q: How do you ensure the quality of the steel?
A: We buy our steel from trusted mills that have rigorous QC. All the materials are tested chemically, mechanically, and they are NDE tested (Ultrasonic, MP) to comply with standard.
Q: How can I prevent corrosion problems in a Hot, humid area?
A: Andhot-dip galvaniz (zinc≥85μm) for the moisture proof. For superior corrosion protection, over 10 years despite of UV, acrylic anti-corrosion paints are coated.
Q: Does corrosion prevention treatment impact on the strength of the steel?
A: No, galvanizing, phosphating or anti-corrosion coatings do not reduce the strength. TheyProtect the steel and allow the steel to maintain its performance and service life.
Q: Are your structures capable of meeting seismic requirements in the Americas?
A: Yes. We design high-seismic-resistant nodes (bolt-connected joints) that absorb earthquake energy and prevent brittle weld fractures. Seismic calculations are in accordance with local intensity.
Q: How do you maintain overall stability?
A: The designs employ well thought out load-bearing elements (portal frames, columns, crane beams) and a system of supports (tie bars, corner bracing) that provide lateral stability under both normal and extreme loading conditions.
