Fabricated Structure
Product Overview
Fully engineered angular lattice towers built from tested structural steel, drilled on CNC lines, and hot-dip galvanized in Nepal's largest kettle for lifelong corrosion protection. Every tower is trial-assembled before dispatch so field erection is bolt-for-bolt predictable.
Designs are prepared to IS 802, ASCE 10 and utility-specific loading trees, with wind and seismic cases modelled for the delivery region.
