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 | Bolted joints for seismic resistance, optimized section for lighter weight and easier transport |
| Steel Column | H300×300 ~ H500×500 (ASTM A36) | Supports floors and frame | Embedded seismic connectors, hot-dip galvanized (zinc ≥85 μm) for humid conditions |
| Crane Beam | W24×76 ~ W30×99 (ASTM A572 Gr.60) | Load-bearing beam for cranes | High-load design (5–20t cranes), end beams with shear-resistant plates |
2. Enclosure system products (weatherproof + anti-corrosion)
Roof Purlins: From C12×20 to C16×31, hot dip galvanized, with a distance of 1.5-2m. They are ideal for color-coated steel panels and typhoon resistance up to level 12.
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-condition.
Support System: Galvanized round steel Φ12~Φ16 and angle (L50×5 steel angle) for bracing strengthen the sideway stability against the wind force of hurricane).
3. Supporting auxiliary products (localized construction adaptation)
Embedded components: Hot-dip galvanized steel plate (10–20 mm thickness) for concrete footing, popular in Costa Rica and other Central American countries.
Bolts: Instead of welding at the job site, high strength bolts (grade 8.8, hot dip galvanized) are used, reducing 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), compliant with local environmental requirements.
STEEL STRUCTURE PROCESSING
| Processing Method | Machines Used | Description |
|---|---|---|
| Cutting | CNC plasma/flame cutters, shears | Plasma or flame cutting for steel plates/sections; shearing for thin plates with precise 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 for H-columns/beams; manual welding for gusset plates; CO₂ welding for thin parts |
| Holemaking | CNC drilling, punching machines | Drilling bolt holes with CNC; punching small batches with precise size and position |
| Surface Treatment | Shot/sand blasting machines, grinder, galvanizing line | Rust removal, weld grinding, hot-dip galvanizing for bolts and structural supports |
| Assembly | Assembly platforms, measuring tools | Pre-assembly of columns, beams, and supports; disassembled after dimensional inspection |

FAQ
Q: What are the specifications of your steel structures?
A: Our steel are American standards used like ASTM A36, A572, A588. A36 is a non-alloy steel having good formability and weldability; A588 is weather-resistant for indoor and outdoor use.
Q: How is steel quality guaranteed?
A: From trusted mills with stringent QC. All steel is tested for chemical, mechanical, and undergoes NDE (ultrasonic, magnetic particle) testing.
Q: How to control the rust in hot and humid areas?
A: We apply hot-dip galvanizing (zinc ≥85 μm). For additional protection, acrylic anti-corrosion paint offers 10 years of UV protection and durability.
Q: Corrosion treatment and strength of steel does it have impact on steel?
A: No. Galvanizing or other anti-corrosion treatments can protect steel without diminishing strength, maintaining performance and extending service life.
Q: Are your products designed to meet the seismic requirements in the Americas?
A: Yes. We employ high-seismic-resistant nodes (bolt-connected joints), as well as conduct local seismic intensity-based calculations so as not to cause brittle weld failures.
Q: How about the stability for the whole structure?
A: Designs Include the well organized load-bearing (portal frame , columns, crane beams) and the supporting system (tie bars, corner braces) which has double function of lateral stability reinforcement under normal and extreme.
