Our engineer and drawer has lots of designing ,lofting experience of lattice steel towers .

Which we can supply a overall solution of all the towers .

4. Quality control

We have very strict quality control in every angle steel towers .

Material incoming control:chemical and physical test

Zinc coating thinknes inspection

We usually has two ways of trial assembly for lattice steel towers : trial assembly before galvanzation

and after galvanization.

6. Hot dip galvanization and painting

7. Package and delivery

Package we usually do as our clients requirment .Usually for angle steel towers,We use steel wire to make it into bundle and use special material to protect the Zinc.
