Product Detail
Product attributes
① Building type:
Portal frame structure
② Main steel structure type:
There are many welded H-shaped components used in the main steel structure of such buildings, as well as truss and other component types.
③ Secondary steel structure:
Support between columns, horizontal support, tie bars, etc.
④ Cladding system:
C-type/Z-type purlins, round steel, corner braces, sleeves
Roofs and walls often use profiled color steel plates, ALC or EPS wall panels

Why choose steel structure buildings?
1. High construction efficiency:
All components are prefabricated in the factory, and the construction site only requires simple assembly, making the construction process relatively safe.
2. Cost savings:
Steel structures are the cost leaders in materials and design for most projects. Its manufacturing and installation costs are low, and it requires less maintenance compared to other traditional building methods.
3. Nice Durability:
Steel structures have good seismic resistance, wind resistance, corrosion resistance, and long service life.
4. Space utilization:
Compared with concrete structures, steel structures can increase the usable area by approximately 6%.
5. Environmentally friendly:
Steel is the material with the highest recycling rate in the world, with an annual recycling capacity of 65 million tons per year, effectively reducing environmental pollution caused by the production of building materials.

Packaging and Delivery
1.Packing steel components and pipe into bundles with steel straps;
2.Wrapping the ends of steel components with fabric;
3.Packaging parts in iron boxes.
Regular goods will be transported in 40ft OT(Opening Top) containers and 40ft HQ (High Cubic)containers.
If we use 40ft HQ, steel pallets are required to pack the goods, and then the pallets are pushed
into the container.When unloading, the entire pallet is pulled out of the container, which can better protect the steel components and quickly unload.
The sea freight for 40HQ is cheaper than the sea freight for 40OT, while due to the using of pallets, the cost will increase.
For 40ft OT, all goods are loaded one by one onto the container using a crane. Because OT are special containers, in this case, the sea freight of 40ft OT is higher.
If you have any other special packaging requirements, please let us know.
