? What’s the difference between Tubular Towers and Angular tower

The question of whether to use angular or tubular towers is always at the background of every project, the answer is not straight forward, because each type of tower is suitable to certain applications. As apparent from Mer Telecom’s line of telecom towers, we have incorporated both designs in order to supply cost effective towers to a wide variety of applications.

What’s the Tubular Steel Poles

Tubular steel poles are another of the major types of transmission towers. They are made up of hollow steel poles. Tubular steel poles can be manufactured as one large piece, or as several small pieces which fit together.

What’s the Lattice Steel Tower?

Lattice steel towers are made up of many different steel structural components connected together with bolts or welded. Many different types of lattice steel towers exist. These towers are also called self-supporting transmission towers or free-standing towers, due to their ability to support themselves. These towers are not always made of steel; they can also be made of aluminum or galvanized steel.

Angular VS Tubular Comparison Table:

Angular Towers Tubular Towers
Members are available in several steel grades Better weight/strength ratio
Members are available in many sizes Lower wind drag brings to smaller foundations
Material is usually less expensive More efficient cross section for buckling
Available in 90° sections, can be bent to 60° Less eccentric connections brings to smaller elements
Fabrication is less expensive (no welding) Large variety of sizes
Transportation is more efficient (better weight/volume ratio) Transportation is more expensive
All surfaces are exposed to the galvanization process All tubes must be open ended to ensure complete galvanizing on the inside

Angular sections are preferred for most small towers with relatively light loads, mainly because of the wide range of sizes, simple connections and low manufacturing cost.

For bigger towers and heavier loads, tubular sections are becoming more useful and more economical. While the costs do differ from one telecom towers manufacturer to another, it is true that the cost of manufacturing is significantly higher, mainly because of the welding process, but the weight to strength ratio is much lower than in angular sections.

What is the Tubular Tower ?

Tubular Tower, which belongs to the technical field of Tubular Tower, includes a work platform for connecting the tower body and the upper part of the tower body. Defines the bottom of the tower wall openings, which wall defines the position of the work platform openings, the antenna holder fixed to the working platform fences, wherein the connector body is provided by a column ladder main rod connected to the main pole and ladder provided The ladder formed by the crosspiece is fixedly connected with the supporting frame of the ladder main rod, and the supporting frame is screwed and matched with the connecting bracket arranged on the inner wall of the tower.

1. All of our material are purchased from famous mill factory to assure the quality
2. A mill certificate issued by the mill factory with stamp and signature must be provided before unload the material in our factory; otherwise we have our reason to refuse the material.
3. Before put into production, all the material must pass the chemical and physical analysis to make sure that they have met the requested strength and component.

The single Tubular Tower includes a tower and a work platform connected to the upper part of the tower body. The antenna bracket is fixed on the fence of the working platform, and is characterized in that the ladder is composed of a ladder block connected to the main pole of the ladder and the main pole of the ladder. The main pole of the ladder is fixedly connected with the supporting frame, and the supporting frame and the supporting frame are arranged on the tower. The inner wall of the connection bracket is screw-fitted.

The advantages of a single Tubular Tower are:. The structure is simple and reasonable; the appearance is beautiful; the installation is easy to use and the floor area is smaller than that of the angle steel tower. In terms of safety, the angle tower is higher than the single tower tower, although the single tower tower is the protagonist. However, if the single-Tubular Tower is to achieve higher safety, only the rod diameter should be increased, the wall should be thickened, and high-strength steel should be used for the material. There will be high cost.
