Roof support bar and roof rise frame are suitable for communication room with no advantage of its height than the surrounding building, and it needs the high strength structure for the building.The roof bracing pole is 15-20 meters high and the triangle is fixed on the roof with reinforced concrete anti-beam. The whole structure is relatively simple and the weight is relatively light. Product advantages: suitable for building in the roof, peak and other areas, products are easy to move and quick installation.

★ 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.
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.
