MEGATRO Three tube or tribular Telecom Tower
This photo refers to our Three tube or tribular Telecom Tower it is widely used in our Chinese market. Some of technical features of this tower as follow:
Tower typeMEGAYRO Three tube or tribular Telecom Tower
Define Three-tube tower refers to tower column is made of steel pipe, and the Tower body section is a three-side-shaped free-standing high-rise steel structure.
Main Features Tower column of three tube towers. The steel pipe is made, the section of the tower is three-side shape, it is a kind of tall steel structure different from the angle steel tower, the welding work is very heavy.
Applicable wind pressure ≤ 0.65 kn/M2
Applicable height ≤50M
Maintenance Platform According to the antenna hanging high and antenna size, flexible adjustment platform spacing, increase the number of platforms or holding Poles.
Disadvantages Advantages: Compared with the traditional angle steel tower, the section of the tower is three-side shape, the number of components is reduced, the economy is good, the area is small, the structure is simple, the construction is convenient and the installation period is shortened significantly. Luck requirements for two times are low.
Disadvantages: Three Tube tower stiffness Weaker Anti-twist Difference, not suitable for microwave tower, height should not be higher than 55m; the shape belongs to the ordinary tower, no landscape considerations. There are many components and many nodes, so it is more difficult to relocate and reuse.
Applicable scenarios1)Three tube towers applyThe scene is wide, especially suitable for the small area of the proposed site, save the construction land.
2 Industrial Development zone, such as suburban areas, county, township, rural areas, such as low demand for landscape, easy to land expropriation areas.
Construction period 3-5-day installation of tower body: Type Foundation Construction: 30-40 days, prefabricated Foundation can shorten the time limit greatly.
Base form Depending on the geological situation, Three-tube towers can be the basic forms used are: Prefabricated assembling foundation, Independent Foundation,Foundation of Raft Board, Pile Cap Foundation and other basic forms.
Cost11000-12500 per ton

Today, with over 10 years of experience and our commitment to excellence, MEGATRO remains an industry leader in the manufacture and design of steel tubular & angular & monopole structures for all Highway, Municipal, Custom, telecom, lighting and electric Utility applications. MEGATRO has a complete staff of professional engineering personnel trained in the PLS Pole program and three different manufacturing processes for producing steel towers, poles and other supports. We utilize the latest versions of PLS-CADD, PLS-POLE, TOWER, AutoCAD and other CAD software.

The structure shall be designed according to load combinations given as per IEC 61936-1 and as illustrated below:
Normal loads
1 Dead weight load
2 Tension load
3 Erection load
4 wind load
Exceptional loads
1 Switching forces
2 short-circuit forces
3 Loss of conductor tension
4 Earthquake forces

Moreover, MEGATRO is fully equipped and qualified to carry out Design Engineering services which includes:
√ Overhead Transmission line steel tower & Telecom steel tower
   Basic Design and Analysis
√ Shop Erection Drawings
√ As-Built Drawings

MEGATRO performs in-house design activities specializing in electrical overhead transmission &telecom tower steel works, which include wind and earthquake loading, static analysis, stress analysis by finite element methods and fatigue. Our Engineering Department is boasting of highly qualified engineering who are conversant with international codes and standards.
