| Software they used | TTA,STWXP,TMA,LMA,Daoheng |
4. Quality control
We have very strict quality control in every steel towers .
Material incoming control:chemical and physical test
Zinc coating thinknes inspection
We usually has two ways of trial assembly for 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.
