Product Description
We design, fabricate and install lattice towers across the China for some of the biggest names in the meteorological, telecommunications, utilities and aviation sectors.
From initial conception through to final installation and rigging, as well as ongoing maintenance, we provide a full turnkey service. What's more, we don't rely on 'off the shelf' solutions. We work closely with our customers to understand what they need, ensuring that our lattice towers are designed and manufactured to their precise requirements.
We have fabricated, installed, maintained and upgraded a number of lattice towers across China, including guyed masts, rooftop towers, transmission towers, radar towers and free-standing steel towers.
We have experienced teams of designers, project managers, steel fabricators, civils and installation teams who will look after every aspect of the project from start to finish, meaning you have greater control from the very start of any project knowing that you will be working with one supplier for that turnkey solution.
