4. Quality control
We have very strict quality control in every electric power tower.
Material incoming control:chemical and physical test
Zinc coating thinknes inspection
We usually has two ways of trial assembly for angle 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 fixed angle steel by
steel wire to bundles and use special material to protect zinc .
For fasteners ,we use bucket ,bag or box.
