Free Standing Tower. These towers are made to EIA/TIA specifications. The towers are fully hot dipped galvanized after fabrication to assure best corrosion protection available. All metal is mill certified. All of the towers components are 100% inspected before they are shipped. This inspection includes clean bolt holes, removal of galvanized drips that will cut and harm installers, all components fit correctly, and all instructions, labeling are correct, and all welds and fabrication is done correctly. 

A partially guyed tower is a tower structure which consists of a free-standing basement, in most cases of concrete or of lattice steel with a guyed mast on the top. The anchor basements of the guyed mast can be on the top of the tower or on the ground.

A guyed mast is a tall thin vertical structure that depends on guy lines for stability. The mast itself has the compressive strength to support its own weight, but does not have the shear strength to stand unsupported, and requires guy lines to resist lateral forces such as wind loads and keep it upright. Guy lines are diagonal tensioned cables attached to the ground, usually spaced at equal angles about the structure’s base.

1. The tower is resistant to wind and typhoon above level 12, and the seismic intensity is 8 degrees. Under the effect of the average maximum wind speed in the local 30 years, the torsion angle and deflection of the tower shall not exceed ±0.4°, and the horizontal displacement at any point on the tower shall not exceed 1/100 of the height of the point.

  2. The verticality of the tower ensures that the vertical deviation of the tower center should not be greater than 1/1500 of the height of the whole tower, and the vertical deviation of the adjacent two layers is ≤1/750.

3. The tower body material is hot-dip galvanized and anti-corrosive.
