APPLICATION

Steel Structure Building: Steel structures are supported by high strength steel, which brings the great advantages of being earthquake-proof, wind-proof, speedy in construction and flexible in space.

Steel Structure House: Steel structure homes adopt lightweight steel framing construction that they save energy, protect environmental, have thermal insulation, and least investment duration.

Steel Structure Warehouse: Steel structure warehouse with being large span, high space utilization, rapid installation, easy to design.

Steel Structure Factory Building: Steel structure factory buildings have a strong load bearing capacity and large areas can be designed without the need for columns, which makes these buildings ideal for manufacturing and industrial applications.

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	High-seismic node design (bolted connections to avoid brittle welds), optimized section to reduce self-weight for local transport
Steel Column	H300×300 ~ H500×500 (ASTM A36)	Supports frame and floor loads	Base embedded seismic connectors, hot-dip galvanized surface (zinc coating ≥85μm) to resist high-humidity corrosion
Crane Beam	W24×76 ~ W30×99 (ASTM A572 Gr.60)	Load-bearing for industrial crane operation	High-load design (suitable for 5~20t cranes), end beam equipped with shear-resistant connection plates

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

Roof purlins: C12×20~C16×31 (hot-dip galvanized), spaced 1.5~2m apart, suitable for color-coated steel plate installation, and resistant to typhoon loads up to level 12.

Wall purlins: Z10×20~Z14×26 (anti-corrosion painted), with ventilation holes to reduce humidity in tropical factories.

Support system: Bracing (Φ12~Φ16 hot-dip galvanized round steel) and corner braces (L50×5 steel angles) enhance the structure's lateral resistance to withstand hurricane-force winds.

3. Supporting auxiliary products (localized construction adaptation)

1.Embedded parts: Steel plate embedded parts (10mm-20mm thick,HOT galvanized),suitable for the concrete foundation normally used in Central America;

2.Connectors: High-strength bolts (grade 8.8, hot-dip galvanized), It eliminates the need to weld on site and reduces the period of construction;

3.Water-based fire retardant paint (fire resistance ≥1.5h) and acrylic anti-corrosive paint (UV protection, life span ≥10years) that meet the local environmental protection regulations.

STEEL STRUCTURE PROCESSING

Processing Method	Processing Machines	Processing
Cutting	CNC Plasma/Flame Cutting Machines & Shears	CNC plasma/flame cutting (for steel plates/sections), shearing (for thin steel plates), is under controlled dimension 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 apparatus, handheld arc welder, CO2 gas-shielded arc welder	SAW (for H-shaped columns and beams), MMAW (for gusset plates), CO₂ gas shielded arc welding (for thin-walled parts)
Holemaking	CNC drilling and punching machine	CNC drilling (for bolt holes in connecting plates/components), punching (for batch small holes), with controlled hole diameter and position tolerances
Treatment	Shot blasting/sand blasting machine, grinder, hot-dip galvanizing line	Elimination of rust (shot blasting/sand blasting), grinding of weld (for deburring), hot-dip galvanizing (for bolts/supports)
Assembly	Assembly platform, measuring fixtures	Pre-assemble elements (columns + beams + supports) and disassemble after dimensional verification for shipping.

STEEL STRUCTURE TESTING

1. Salt spray test (core corrosion test) Standards ASTM B117 (neutral salt spray) / ISO 11997-1 (cyclic salt spray), suitable for the high-salt environment of the Central American coast.	2. Adhesion test Cross-hatch test using ASTM D3359 (cross-hatch/grid-grid, to determine peeling level); pull-off test using ASTM D4541 (to measure peel strength between coating and steel substrate).	3. Humidity and heat resistance test Standards ASTM D2247 (40°C/95% humidity, to prevent blistering and cracking of the coating during rainy seasons).
4. UV aging test Standards ASTM G154 (to simulate strong UV exposure in rainforests, to prevent fading and chalking of the coating).	5. Film thickness test Dry film using ASTM D7091 (magnetic thickness gauge); wet film using ASTM D1212 (to ensure corrosion resistance meets specified thickness).	6. Impact strength test Standards ASTM D2794 (drop hammer impact, to prevent damage during transportation/installation).

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:
Steel structures are rigorously packaged to protect the surface and ensure the structure during the process of handling and shipping. The parts are usually wrapped with a waterproof material such as plastic film or rust-proof paper, while the smaller accessories are packed into wooden boxes. On the other hand, all the bundles or sections are individually identified, making it easy to unload safely and install competently at the site.

Transportation:
Steel structure can be transported in container or by bulk ship according to size and destination. Large or heavy items are strapped using steel straps with wood on either edge to prevent movement and damage while in transit. All logistcs are performed under international transport standards for ensuring delivery on time and safe arrival, even for long distance or international shipping.

FAQ

Regarding Material Quality

Q: What standards are your steel structures in compliance with?
A: Our steel structure meets with the American Standards like ASTM A36,ASTM A572 and so on. For instance, ASTM A36 is a general purpose carbon structural, A588 is a structural with high – weather – resistanc suitable to be used in severe atmospheric environments.

Q: How can you guarantee the quality of steel materials?
A: We obtain steel materials from the reputable domestic or overseas steel mills which have stringent quality control system. All the products are subject to rigorous tests when they arrive, included is the analysis of the chemical composition, the testing of mechanical properties and the non-destructive testing such as Ultrasonic testing (UT) and Magnetic Particle Testing (MPT) in order to testing the quality whether accorded with related standards.
