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.
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.
Angular VS Tubular Comparison Table:
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 |
