AL220 Aluminium Roof Mounted Lattice Tower - 18.9 metres, Stainless Guy Wires

With the surging demand for wireless point-to-multipoint services, WISPs face the challenge of maximizing site and spectrum utilization. Traditionally, tall 'telomasts' have been used, but these are not suitable for multiple sectors and high-gain dishes. APAC has met this challenge head-on with our innovative ultra-lightweight, climbable, aluminum lattice towers that can be easily raised on a roof with a small team.

Key Features of APAC's Roof Lattice Towers:

• Modular Design: The towers consist of a large universal-joint base plate, modular 3.1-meter lattice sections, guy wires, and customizable headframes. This design allows for flexibility, enabling the construction of towers as short as 3.1 meters, with full structural engineering certification up to 37.2 meters (or 21.7 meters in Wind Region C).

• Sturdy and Lightweight: Our AL220 aluminum lattice modules feature three upright columns made from 40x3 round tube, with 25x3 round tube lattice braces welded by certified boom welders. This construction ensures incredible strength while maintaining a lightweight design, allowing technicians to safely climb the full height.

• Safety First: The tower base is built with a 50-tonne rated, fully machined billet aluminum universal-joint. This design allows axis locking for safe and easy raising. The solid structural grade aluminum components provide absolute peace of mind regarding the tower's integrity.

Additional Benefits:

• Lightweight and easy to raise
• Fully engineered design
• Climbable to a full height of 18.6 meters
• Low maintenance due to durable aluminum construction
• Equipped with 6 mm 7x19 galvanized steel guy wires
• Convenient 3100 mm section lengths

APAC's aluminum lattice towers are the perfect solution for WISPs looking to optimize their wireless services efficiently and safely.
