Industrial Steel Structure Buildings for Warehouse, Workshop and Factory Construction
Steel Truss Frame Structure for Modular Building The Engineered Steel Building is a kind of spatial structure, in the construction of building, the steel components are combined in different ways to constituted the rigid frame. Triangular shape delivers more strength and stability with less material and is more ideal for long span and open room.
Outstanding Features
High Strength-to-Weight Ratio -- Triangular truss geometry enables high load capacity with less steel.
Wide Clear Span It has wide max.depth. No more internal columns needed.
Multi-Purpose Design – For use in warehouses, workshops, manufacturing plants, and auditoriums & sportshalls.
Pre-Fabrication & Rapid Assembly – Steel components are pre-cut and formed off-site, then rapidly bolted on-site together.
Durability - With suitable corrosion protection (galvanizing, painting or coating) a steel building can endure for many years.
Parts
Top Chord: The upper horizontal or sloped member of the truss.
Bottom Chord: The bottom horizontal member is in tension.
Web Members Triangular cells are made of diagonal and vertical members.
Connections: Bolted or welded seams connecting the members
Bracing (Optional): Additional lateral restraint for longer spans.

1. Overseas Branches and Multilingual Communication Support (Spanish, Russian, etc.)
To better meet the needs of overseas markets, we collaborate with other overseas offices to serve global clients primarily in English and Spanish.
Our team streamlines customs clearance processes, document preparation, and export requirements to meet your delivery deadlines and help you complete imports faster.
2. Ample Stock, Fast Delivery
We maintain a sufficient inventory of standard raw materials for hot-rolled steel structures (H-beams, I-beams, and steel structure fittings).
This means shorter delivery cycles, allowing customers to quickly obtain reliable products to meet the needs of "urgent" projects.
3. Professional Packaging
All products are packaged in standard sea freight packaging; customized packaging is also available for enhanced protection against damage.
This ensures safe loading, prevents displacement during long-distance transport, and ensures no damage upon arrival at the destination port.
Treatment on surface Display: Epoxy zinc-rich coating, Galvanized(hot dip galvanized layer thickness≥85μm service life can reach 15-20 years), black oiled, etc.

Packing Details
All steel parts are well packed for surface finishing and shape maintaining during handling and transportation. Main members are wrapped in watertight plastic film or anti-rust paper, while bolts, connectors and other small accessories are put in wooden boxes. For your convenience, each package is labeled so you can identify, unload and install safely and efficiently on site.
Delivery
Prefabricated Steel Building are delivered via container vessel or bulk vessel depending on the size of the project, the dimensions and the destination. Large and bulky items are tightly strapped with steel straps or wooden crats to prevent moving in the journey. Every order is processed following international transportation standards to be delivered safely and on-time.
Q1: Can you make Steel Building as per our drwaings?
A: Yes. We offer customizedplant design, fabrication and engineering services from your drawings or aimed at your project needs.
Q2:Which steel grades you are using?
A: We use ASTM A36, ASTM A572, ASTM A992, Q235B, Q355B and other structural steels that meet international standards as our typical materials.
Q3: What kind of surface treatment can be chose?
A: Finishes offered include painted, hot-dip galvanized, epoxy-coated and various other protective formats ideal for different service environments.
