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 beam for roof/wall load-bearing	Seismically capable nodes use bolted flanges instead of welds, which are brittle, and are optimized for lighter, more convenient transport.
Steel Column	H300×300 ~ H500×500 (ASTM A36)	Supports frame and floor loads	The seismic base plate connectors are hot-dip galvanized (≥85 μm) for providing a minimum corrosion protection in humid atmosphere.
Crane Beam	W24×76 ~ W30×99 (ASTM A572 Gr.60)	Load-bearing for industrial crane operation	Heavy-duty (5–20 ton cranes) with end beams equipped with shear resistant plates.

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

Roof Purlins: C12×20–C16×31 (hot-dip galvanized) with center distance of 1.5–2m is applicable for the installation of color-coated steel sheet and has the anti-typhoon up to level 12 ability.

Wall Purlins: Z10×20-Z14×26 (anti-corrosion painted) with ventilation holes to reduce condensation in tropical factory environment.

Support System: A bracing (Φ12–Φ16 hot-dip galvanized round steel) and corner brace (L50×5 steel angles) enhances lateral stiffness and ensures excellent performance under winds up to hurricane.

3. Supporting auxiliary products (localized construction adaptation)

1.Paneles integrales: Placas de acero galvanizado (10–20 mm), con la misma capacidad de soporte que las cimentaciones de concreto normales en Centroamérica.

2.Conectores: Con tornillos de alta resistencia grado 8.8 galvanizados en caliente; sin soldaduras.

3.Recubrimientos: Pintura intumescente base agua (≥1,5 h) y pintura acrílica anticorrosiva con protección UV (vida útil ≥10 años), cumple con la normatividad ambiental local.

STEEL STRUCTURE PROCESSING

Processing Method	Processing Machines	Processing
Cutting	CNC plasma/flame cutting machines, shearing machines	CNC plasma/flame cutting (for steel plates/sections), shearing (for thin steel plates), with controlled dimensional accuracy
Forming	Cold bending machine, press brake, rolling machine	Cold bending (for C/Z purlins), bending (for gutters/edge trimming), rolling (for round support bars)
Welding	Submerged arc welding machine, manual arc welder, CO₂ gas-shielded welder	The H-beams and columns are submerged arc welded, the gusset plate is arc welded manually and the thin walled sections are welded with co2 gas.
Holemaking	CNC drilling machine, punching machine	CNC drilled for bolt holes and punched for short runs, guaranteeing hole size and location.
Treatment	Shot blasting/sand blasting machine, grinder, hot-dip galvanizing line	Rust removal (shot blasting/sand blasting), weld grinding (for deburring), hot-dip galvanizing (for bolts/supports)
Assembly	Assembly platform, measuring fixtures	Pre-assemble components (columns + beams + supports), disassemble after dimensional verification for shipment

STEEL STRUCTURE TESTING

1. Salt spray test (core corrosion test) Complies with ASTM B117 - ISO 11997-1 for Salt Fog Corrosion Resistance for use in Central American Coasts.	2. Adhesion test Crosshatch (ISO 2409/ASTM D3359) and Pull-off (ISO 4624/ASTM D4541) to control adhesion and peel strength of the coating.	3. Humidity and heat resistance test ASTM D2247 (40 C/95% RH) to inhibit blistering and cracking in rain.
4. UV aging test ASTM G154 is recommended for protection against UV-induced fading and chalking in pnl exposure in automobiles.	5. Film thickness test Dry (ASTM D7091) and Wet (ASTM D1212) Film Thickness Measurements to Achieve Necessary Corrosion Protection.	6. Impact strength test ASTM D2794 (drop hammer) protects coatings during transport and storage.

SURFACE TREATMENT

Surface Treatment Display: Epoxy zinc-rich coating, galvanized (hot dip galvanized layer thickness ≥85μm service life can reach 15-20 years), black oiled, etc.

PACKAGING AND SHIPPING

Packaging:
The steel structure is tightly packed to ensure safe delivery: large components are wrapped in waterproof sheets, small parts assembled and labeled in wooden boxes to facilitate unloading and building.

Transportation:
It is possible to transport steel structures by container or bulk ship and big components can be fastened with steel straps and wooden wedges to comply with deliver standards.

FAQ

Regarding Material Quality

Q: What are the quality standards of your steel structures?
A: Our steel is in accordance with American standards such as ASTM A36 for (carbon structural steel) and ASTM A588 (high weather resistant steel for aggressive environments).

Q: How to test the quality of steel?
A: We purchase from a few good mills and test all material on receipt, both chemical, mechanical, and non destructive tests (radiography, ultrasonic, magnetic particle and visual) to the extent that is required by applicable standards.
