There are several common specifications of lightning protection towers, including GFL angle steel lightning tower, GJT round steel lightning rod tower, GH steel pipe pole lightning rod tower, and other forms of metal towers.
GFL lightning protection towers are mainly used for lightning protection projects in various buildings, especially in refineries, gas stations, chemical plants, coal mines, warehouses, and flammable and explosive workshops. It is even more important to install lightning protection towers in a timely manner. Due to climate change, lightning disasters continue to worsen. Nowadays, many buildings are equipped with lightning protection towers, especially stainless steel decorative iron towers on the roofs, which have diverse shapes, beautiful appearances, and novel and unique designs. They are widely used in buildings such as rooftops, squares, and green spaces in residential areas, making them complement each other and become iconic decorative buildings in cities. The principle of lightning protection tower is the same as that of lightning rod. Reduce lightning disasters.
Using steel pipes as the tower column material, the wind load coefficient is small and the wind resistance is strong. The tower column is connected by an external flange, with bolts under tension, which is not easily damaged, saves steel, has a small follow-up, occupies a small area, saves land resources, is conveniently located, has a light weight of the tower body, is easy to transport and install, has a short construction period, and is designed with a wind load curve that changes smoothly. It is not easy to collapse in rare wind disasters and reduces casualties of people and animals.
The design complies with national steel structure design specifications and tower mast design regulations, and the structure is safe and reliable Anti damage ability: Wind level 10/Earthquake level 6 Lightning protection principle: Lightning current arrester is a non inductive, low impedance metal inner conductor down conductor, which transports the lightning current after flashover to the ground and prevents the protected antenna tower or building from side impact and electrification In most cases, the impact of static electric field cables is less than 1/10 of the impedance of the iron tower, which avoids the electrification of buildings or iron towers, eliminates lightning strikes, limits the current intensity of landmines, and reduces the harm of counterattacks and induced overvoltages to the protected equipment. The protection range is calculated according to the GB50057 rolling ball method

Lightning protection tower Design basis:
1. Building lightning protection design code (GB50057-94)
2. High rise structure design code (GBJ135-90)
3. Steel structure design code (GB50017-2003)
4. Construction and acceptance code for tower and mast steel structure (CECS80:2006) Lightning protection tower is a common type of lightning protection tower.
A tower type lightning protection device used to protect buildings from lightning strikes. Install a lightning protection tower next to the protected building to connect it to the ground grid, achieving the effect of triggering lightning and preventing accidents.
