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: Hot-dip galvanized purlins C1220–C1631 with the spacing of 1.5 - 2m are suitable for color-coated roofing sheets and can apply typhoon up to 12-level in the weather.

Wall Purlins: Z10×20–z14×26 ventilated purlins with holes painted to reduce condensation in tropical factory conditions.

Support System: Lateral stability is enhanced by Φ12–Φ16 round-steel bracing and L50×5 angle corner braces, which also guarantee dependable operation at speeds equivalent to hurricane winds.

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 Description
Cutting	CNC plasma/flame cutting machines, shearing machines	CNC plasma/flame cutting for steel plates/sections; shearing for thin plates; ensures precise dimensions.
Forming	Cold bending machine, press brake, rolling machine	Cold bending for C/Z purlins; bending for gutters and edge trims; rolling for round support bars.
Welding	Submerged arc welding machine, manual arc welder, CO₂ gas-shielded welder	H-beams and columns welded by submerged arc; gusset plates welded manually; thin-walled sections welded with CO₂ gas.
Holemaking	CNC drilling machine, punching machine	CNC drilling for bolt holes; punching for small-batch production to ensure accurate hole size and position.
Treatment	Shot blasting/sand blasting machine, grinder, hot-dip galvanizing line	Rust removal via blasting; weld grinding for smooth finish; hot-dip galvanizing for bolts and supports.
Assembly	Assembly platform, measuring fixtures	Components (columns, beams, supports) are pre-assembled, dimension-checked, then disassembled 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.

FAQ

Regarding Material Quality

Q: What are the quality standards of your steel structures?
A: Our steel complies with American standards like ASTM A36 for (carbon structural steel) and ASTM A588 (high weather resistant steel for aggressive atmospheres).
Q: How to test the quality of steel?
A: We buy from a handful of good mills and test everything upon receipt, chemically, mechanically, and NDT (radiography, ultrasonic, magnetic particle, and visual) to the extent that is dictated by the applicable standards.
