Lightning tower

Introduction：

Lightning tower is mainly used in lightning protection project of various buildings, Main types: GFL angle steel lightning rod tower, GJT round steel lightning rod tower, GH steel pipe pole lightning rod tower, and so on.

Structure features：

1. Lightning tower mainly adopts round steel, angle steel, steel tube as material of pylon. Small wind load coefficient, strong wind resistance. With excellent stability， pylon is connected by flange or bolts

2. Generally, most shapes are equilateral triangle (saving steel and land resource). Light weight, convenient for transportation and installation, and short construction period.

Functions：

Lightning tower is mainly used in lightning protection project of various buildings, particularly refinery, gas station, chemical plant, coal mine, explosive depot, inflammable and explosive workshop, should be placed lightning tower timely. Considering the climatic change and increasing Lightning disasters, more buildings are in great need of lightning towers, especially roof stainless steel tower. Great variety of styles and gorgeous appearance make lightning tower widely used in the green space on the roof, square, and residential area. Surrounded by the constructions, lightning tower becomes the symbolic ornamental building in the city.
