Prefabricated Steel Frame Structure Building Multi-story Steel Apartment Buildings Factory Q355B Steel Structure Warehouse
Steel Structure Building Construction
Steel structure building is constructed with superior high strength steel, which can provides excellent seismic performance, wind resistance, quick construction and modern design.The optimize load-bearing system and lightweight components enable them to span longer span, reduce foundation load and can be used in severe environment.With modular design of prefabricated parts for installation time can be further reduced as well as labor costs.
Steel Structure House
Durable, energy efficient long term houses with pre-engineered constructs system. With more advanced insulation materials home E comfort is improved, while energy consumption is lowered. Constructed from recyclable steel, these houses are eco-friendly, rapidly assembled, cost-effective and easily modified to accommodate modern housing needs.
Steel Structure Warehouse
Without the need for steel warehouses with large clear span, high space utilization, and fast erection. Their flexible design caters to column free layouts from 20 to 100+ meters for optimised storage and forklift operations. Additional features including insulated panels, skylights, ventilation, and crane systems, allow for use in logistics, cold storage, and industrial warehousing— meanwhile the relatively low structural weight accelerates construction and reduces up keep.
Steel Structure Factory Building
Steel factory buildings offer large, unobstructed areas for open production with no interior columns Custom Designed Steel Buildings Breaking the Mold Gone is the cookie-cutter steel building style of the past. This makes them perfect for build-to-suit for manufacturing, processing plants, and work shops and warehouses. They are easily adapted for overhead cranes, mezzanines, and heavy machinery and provide long service life, safety and easy future expansion.

1. Overseas Branches & Spanish-Speaking Support
We have offices overseas staffed with professional Spanish-speaking teams in order to maintain communication with clients in Latin America and Europe. Our team takes care of customs clearance and documentation and organizes the logistics, so you can enjoy a consistent supply and accelerated imports.
2. Ready Stock for Fast Delivery
We have a sufficient stock of the commoned steel materials, such as H-beams, I-beams, HSS and other standard structural steel. Having stock on hand enables us to deliver products quicker and more reliably, which is a critical factor when dealing with urgent and time-sensitive projects.
3. Professional Packaging Solutions
All products are packed in a standard seaworthy way with steel frame bundling, waterproof layering and edge protection. During loading, this will protect a safe loading, good stability for long distance transport and getting no hurt in destination port.
4. Good Quality Efficient Shipping & Delivery Service
We work with trustworthy domestic shipping agents with delivery term including FOB, CIF a... DDP. Sea, rail or road - we will ensure timely shipping schedules and provide you with the logistics tracking facility to efficiently monitor every stage of your delivery.
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.

Packaging
The steel products are carefully packed to prevent its surface from being damaged and to avoid the deformation in the handling and transportation. Each part is packaged with waterproof material like plastic film or anti rust paper, smaller accessories are put in wooden box to keep indoors. All sections and bundles are labeled with the clear marking for safe unload and easy installation on site.
Transportation
Steel fabrications can be shipped by container or break bulk vessel according to size and port of destination. Big or heavy pieces are banded with steel strapping and wooden blocks are placed on end to keep the load stable while travelling. International transportation standards are observed in all logistics processes to guarantee the timely delivery and safe arrival even at long distance and for overseas shipping.
About material quality issues
Q: Standards compliance What are the standards applicable in your steel structures?
A: Our steel structure complies with the American Standards such as ASTM A36,ASTM A572 etc. for example: ASTM A36 is a general purpose carbon structural, A588 is a high – weather – resistanc structural suitable to be used in severe atmospherics.
Q: How do you control the quality of steel?
A: The steel materials are from the well-known domestic or international steel mills which has strict quality control system. When they arrived, the products are all tested rigorously, including the chemical composition analysis, the mechanical properties testing and the nondestructive testing, such as the ultrasonic testing (UT) and magnetic particle testing (MPT), to check if the quality meets with related standards.
