Angular or Tubular Towers?

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:

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
