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

4. Quality control

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

Material incoming control:chemical and physical test

Zinc coating thinknes inspection

We usually has two ways of trial assembly for tranmsmission 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 transmission steel towers,we fixed angle steel by

steel wire to bundles and use special material to protect zinc .

For fasteners ,we use bucket ,bag or box.
