APPLICATION

Warehouses and Logistics Centers: Prefabricated steel sructure buildings enable rapid, economical construction of warehouses and distribution centers. Modular components permit rapid construction while providing structural integrity and durability.

Industrial factories and plat production:High load-bearing industrial processes are supported by robust steel frameworks, such as H-beam, I-beam, steel plate. These are well-suited for equipment platforms, production lines and factory floors.

Bridges and Infrastructure Projects: Steel construction is prevalent in the building of bridges, highways, and energy infrastructure because it can meet complex engineering requirements with strength, accuracy and flexibility.

Commercial and public buildings: Prefabricated steel frames offer a modern and flexible solution for commercial construction, such as for office buildings, shopping centres and sports halls.

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
Portal Frame Beam	W12×30 ~ W16×45 (ASTM A572 Gr.50)	Primary load-bearing beam for roof and wall systems	Seismic-grade bolted connections; lightweight structural optimization for easier inland transportation
Steel Column	H300×300 ~ H500×500 (ASTM A36)	Main vertical support for floors and structural frames	Seismic-resistant connectors; hot-dip galvanized coating (Zn ≥ 85 μm) for high-humidity environments
Crane Beam	W24×76 ~ W30×99 (ASTM A572 Gr.60)	Designed for overhead crane systems (5–20 tons capacity)	High-strength design with shear plate end connections; optimized structural weight reduction for cost efficiency

2. Enclosure system products (weatherproof + anti-corrosion)

Roof Purlins
C12×20 to C16×31 sections, hot-dip galvanized finish, with spacing of 1.5–2.0 meters.
Designed to support color-coated steel roofing panels and engineered to withstand typhoon wind speeds up to Level 12.

Wall Purlins
Z10×20 to Z14×26 profiles with anti-corrosion coating (salt spray resistance exceeding 1000 hours).
Integrated ventilation openings to reduce internal condensation, making them suitable for tropical factory environments.

Bracing & Support System
Galvanized round steel bars (Φ12–Φ16) and angle steel (L50×5) used for structural bracing.
Enhanced lateral stability to resist hurricane-level wind loads and improve overall frame rigidity.

3. Supporting auxiliary products (localized construction adaptation)

Precast Part: Hot-dipped galvanized steel plate (thickness 10–20 mm) for concrete footing, for sale in Costa Rica and for import in other Central American countries.

Bolts: High strength bolts (galvanized, grade 8.8) are used in place of welding in field, minimizing the assembly time.

Fire & Corrosion Protection: Water based intumescent coating (≥1.5 h fire protection), UV stable acrylic anti-corrosive coating (≥10 years service life), following local environmental protocols.
