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 and wall load-bearing beam | Seismic resistant bolted joints and section optimized for weight reduction and easy transportation. |
| Steel Column | H300×300 ~ H500×500 (ASTM A36) | Supports floors and frame | Inserts Seismic connectors, hot-dip galvanized (zinc layer min. 85 μm) for humid conditions. |
| Crane Beam | W24×76 ~ W30×99 (ASTM A572 Gr.60) | Load-bearing beam for cranes | High capacity design (5–20t hoists), end beams fitted with shear plates |
2. Enclosure system products (weatherproof + anti-corrosion)
Roof Purlins: From C12×20 to C16×31, hot dip galvanized, at a distance of 1.5-2m. They are excellent for color coated steel panels and typhoon resistance of 12 level.
Wall Purlins: Z10×20 to Z14×26 with anti-rusting paint (dried salt spray over 1000 hours) - also has ventilation holes to ventilate the tropical factory moisture-condit.
Support System: Galvanized round steel Φ12~Φ16 and angle (L50×5 steel angle) for bracing strengthens the sideway stability against the wind force of hurricane).
3. Supporting auxiliary products (localized construction adaptation)
Precast component:Hot-dip galvanized steel plate (thickness: 10–20 mm) for concrete footing, commercially available in Costa Rica, imported into other Central American countries.
Bolts:High strength bolts (grade 8.8, hot dip galvanized) are used in place of welding at the job site, minimizing the erection time.
Fire & Corrosion Protection: Water based intumescent coating (≥1.5 h fire protection), UV resistant acrylic anti-corrosive coating (≥10 years service life), meeting local environmental regulations.
STEEL STRUCTURE PROCESSING
| Processing Method | Machines Used | Description |
|---|---|---|
| Cutting | CNC plasma/flame cutters, shears | Plasma, flame cutting for steel plates/sections, shearing for thin plates with accurate size. |
| Forming | Cold bending machine, press brake, rolling machine | Cold bending for C/Z purlins, gutters, edge trims rolling for round support bars. |
| Welding | Submerged arc, manual arc, CO₂ welders | Submerged arc welding for H-columns/beams; manual welding for gusset plates; CO₂ welding for thin sections. |
| Holemaking | CNC drilling, punching machines | Bolt hole drilling with CNC; punching small batches with exact size and position. |
| Surface Treatment | Shot/sand blasting machines, grinder, galvanizing line | Rust removal, welding grinding, hot-dip galvanizing for bolts and structural supports. |
| Assembly | Assembly platforms, measuring tools | Columns, beams and bracings pre-assembled; taken apart after dimensional checks. |

PACKAGING AND SHIPPING
Packaging:
The steel is well packed with surface protection and stiffness maintaining agent for handling.
Small accessories are packaged in wooden boxes, with waterproof wrapping, plastic or rust-proof paper.
Boxes and bundles are labelled clearly so that they may be safely unloaded and efficiently installed.
Transportation:
Container or bulk vessel shipping depending on load size and destination.
Bulky or heavy goods are restrained from moving using steel strapping and wood blocks.
All delivery conform to international transport regulations for delivery security and reliability.
