What Is 4 Legged Angular Steel Tower?
The angle steel tower is an iron tower whose main body is made of angle steel. It is the most common type of communication angle tower and is now spread all over the country. Angular sections are preferred for most towers with relatively light loads, mainly because of the wide range of size, simple connections and low manufacturing cost.
4 legged angular steel tower is a kind of self-supporting communication tower. It can also be called 4 legged angular steel communication tower, telecommunication tower, antenna tower.
4 legged angular steel tower are higher steel structures used all over the world for communication applications. Their function is to support antennas for telecommunications, broadcasting and WIFI internet. 4 legged angular steel tower usually comes with pre-designed accessories, just like platforms, ladders with cable tray, antenna brackets, aviation light brackets and fall prevention device, etc.
4 legged angular steel tower are based on either ground or building, and they are commonly designed in trusses structure to carry the wind loads and seismic loads. 4 legged angular steel tower is easy to process, transport and install. The overall rigidity of the angle steel tower is large, the bearing capacity is strong, and the technical application is mature.

A lattice tower is a freestanding framework tower made of steel or aluminium sections. It has a latticed framework type of structure with upright leg elements and interconnecting struts and braces. It can be used for power lines, radio towers, observation towers, or wireless transmission equipment. It is usually triangular or square in plan view and can range from 20 to 400 ft. tall. It is flexible, stable, wind resistant, and easy to access for maintenance and upgrades. The Eiffel Tower is the most famous example of a lattice tower.
