Telecom Mast Construction

Telecommunication Steel Wireless Towers

LEO provides wireless tower design and construction up to 120m. Tower types include lattice wireless towers, monopole wireless towers, and guyed wireless towers.

Field Support

Our professional team provides ongoing support in the field. From site walks to site maintenance, we specialize in getting sites on air and maintaining operational integrity.

Fabrication and Galvanizing

Our wireless tower is fabricated by solid steel pipe with angle or bracing members, which provides great strength, low weight and wind resistance, and economy in the use of materials. Lattices of triangular cross-section are most common, and square lattices are also widely used. After fabrication all towers are delivered to the galvanizing facility to be Hot DIP Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.

Engineering Design

LEO TOWERS will guarantee the overall safety of the tower. LEO TOWERS will submit design calculation report for member design of tower and overall structural stability of the structure, which is signed by a charted structural Engineer. LEO will supply the skeleton to scale, showing the assembly of the structures, the antenna mounting levels, other detail drawings etc. The calculation method to be adopted for tower design will be decided by LEO TOWERS with the consent of the client.

All materials will comply with G, BS, ASTM or equivalent standards. The permissible stress of the materials will comply with GB BS, or equivalent. The standards adopted for all materials will be stated separately. Mast will be designed based on GB, BS 8100, TIA/EIA-222-G-2006, IS 802 & IS875 or equivalent international standards.

The wind loading on the tower and antennas mounted on it will withstand a ground level wind velocity of 140 Km/h and survival speed of 180 Km/h including with height in accordance with latest BSI CP3: Chapter V: Part 2: British Standard (BS). Antennas considered when calculating wind areas include six GSM antennas, two each 600 mm diameter microwave dishes, one 1.2m Microwave, plus feeders for GSM and MW antennas.

Effective Windage Area Allowance

Allowance will be given to the effective windage area of feeder runway, feeders, platforms and guard rails, ladder and ladder guards. LEO submits complete data showing the drag factor from various angles of wind on the antenna offered.

Performance and Special Requirements

Besides conforming to the drawing and design, the materials and fabrication of tower components shall conform to Chinese Standard or other international standard. If any special requirement, we can design and discuss with client.
