Single tube tower and communication rod are belong to the pipe tower technology, including the working platform for connecting the tower body and the upper parts of the tower body.It provides a maintenance door under the bottom of the tower. the working platform should be provided with a door-to-door hole, and the antenna support is fixed on the fence of the working platform. Those utilities are characterized in that the climbing ladders are composed with the inside and outside connector of the main body, the main climbing ladder rod is fixed connected with the supporting frame, and the supporting frame is coupled with the connecting bracket inside the wall of the tower body. Advantages: simple structure, reasonable; beautiful; easy installation and use, less land. The flat surface should be necessary.

★ 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.
