The seamless steel pipe is usually used as the main material of the four tubes tower, which has low wind load coefficient and strong wind resistance. The main body adopts the outer flange connection, the bolt has been pulled, so it is difficult to destroy so that it can reduce the maintenance cost. The tower body has a positive triangle distribution, which accords with the physical law of triangle stability and saves steel materials,small area, reduce the cost of civil construction, convenient location. Light weight of tower, new trefoil cutting plate foundation, it reduces foundation cost. Truss structure design, convenient transportation and installation, short construction period. The tower with wind load curve design and smooth lines so it can avoid human and animal casualties. The design conforms to the national code for steel structure design and the design of tower mast structure Specification, this product is safety and reliability.scope of use: filed self-supporting tower, roof tower.

Product Details Comparison


Our Products
Each soldering seam is full,without solder slag,without solder skips,meet technical requirement.
Other factory’s products
The other factory’s products have solder slag and solder skips,hidden danger.


Our Products
Zinc thickness is:99.7μm.
Other factory’s products
If the zinc thickness is not enough, after some times, it will be rust,hidden danger.

 We are very strictly in controlling the thickness of all the parts in hot-dip galvanization,all those parts stay with corrosion for years.If the process of hot dip galvanization is not good, it is easy to be rusted and affect the safety of the tower.

Product Quality Standard

1. All the original materials and finished products should be 100% checking.

2. We already obtain the  ISO 9001:2008, ISO14001:2005 and OHSAS18001 quality and safety certificate.
