500KV Transmission Line Angle Steel Lattice Tower ,Double Circuit
Q345B Electrical Pylons
1. Production decription
Qingdao Liangta Steel Structure is in the field of steel lattice
tower manufacturing since 2009.
During these years ,we learn and move step by step ,and improve a
lots .If possible ,We want to move together with u lately .

2. Product capacity
We have 5 production line for manufacturing angle steel tower ,We
can supply 3000 tons angle steel towers
per month .And we have enough room to place more angle steel towers production line if needed .
| Numbers of angle production line | 5 |
| production capacity per month | 2000 tons |
3. Technical support
Our engineer and drawer has lots of designing ,lofting experience
of angle steel tower .
Which we can supply a overall solution of all the towers .
| Service you can get from our engineer | tower design,tower lofting ,tower weight calculation and loading
plans |
| Software they used | TTA,STWXP,TMA,LMA,Daoheng |
4. Quality control
We have very strict quality control in every steel lattice tower
Material incoming control:chemical and physical test
Zinc coating thinknes inspection
5. Trial assembly
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.
