Steel Structure Industrial Building:Steel structure industrial buildings are strong, lightweight, and ideal for fast, large-span construction.

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	The high seismic nodes employ bolted flanges to prevent brittleness in welds and have been structurally optimized to minimize the weight for ease of 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) to provide the minimum corrosion protection for use in moist environment.
Crane Beam	W24×76 ~ W30×99 (ASTM A572 Gr.60)	Load-bearing for industrial crane operation	Robust construction (5–20t cranes) with end beams with shear-resistant connection plates.

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

Roof Purlins: C12×20–C16×31 (hot-dip galvanized) with 1.5–2m centers is suitable for color-coated steel sheet installation and can resist typhoon load up to level 12.

Wall Purlins: Z10×20-Z14×26 (anti-corrosion painted) with ventilation holes to minimize dampness in tropical factory conditions.

Support System: Bracing (Φ12–Φ16 hot-dip galvanized round steel) and corner braces (L50×5 steel angles) increase lateral rigidity and guarantee good performance in winds of hurricane strength.

3. Supporting auxiliary products (localized construction adaptation)

1.Partes incrustadas: placas de acero galvanizado de 10 a 20 mm, se adapta a cimentaciones de concreto conocidad en Centroamérica.

2.Conectores: Pernos de alta resistencia grado 8.8, galvanizados en caliente, no es necesario soldar en el sitio, facilitando el montaje.

3.Revestimientos: Pintura ignífuga a base de agua (≥1,5 h) y pintura acrílica anti-corrosiva con protección UV (vida útil ≥ 10 años), en cumplimiento con las normativas ambientales locales.

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) Meets ASTM B117 and ISO 11997-1 salt spray standards, ideal for Central America’s coastal environment.	2. Adhesion test Crosshatch test (ASTM D3359) for coating adhesion, pull-off test (ASTM D4541) for peel strength.	3. Humidity and heat resistance test Conforms to ASTM D2247 (40°C/95%RH) to avoid blistering and cracking of the coating during rainy weather.
4. UV aging test Complies with ASTM G154 to protect against UV caused color fading and chalking under the exposure of the rain forest.	5. Film thickness test Dry film thickness was measured by ASTM D7091 and wet film thickness by ASTM D1212 to achieve the required corrosion-resistant thickness.	6. Impact strength test Complies with ASTM D2794 (drop hammer impact) to safeguard against harm in the course of shipping and handling.

FAQ

Regarding Material Quality

Q:What are the quality standards of your steel structure?
A: Our steel structure complies with American standard such as ASTM A36,ASTM A572. ASTM A36 is a normal carbon structural steel, and A588 is high weather-resistant structural steel for severe atmospheric environment.

Q:How do you check the quality of steel?
A: We purchase with quality in mind and work with mills that have proven quality and a good track record. Every material is subject to a full inspection at the time of delivery, such as: chemical analysis inspection, mechanical properties inspection, observation through non-destructive testing radiography, ultrasonic testing, magnetic particle testing, visual inspection complies to whatever standards needed.
