1.   Production decription

Qingdao Liangta Steel Structure Co., Ltd. ,are manufacturing transmission line tower,telecommunication towers ,monopoles ,substation structures since 2009.
I have been in this field close 10 years ,seen  a lot of things happened in our industry ,In the beginning few years ,i think i know steel tower very well ,while apparently ,i did not .

I am aggie ,the sale manager of Qingdao liangta steel structure Co.,Ltd.If you need us to quote a price or just communicate about the electric transmission tower ,please contact me directly.

Electrical transmission towers Voltage from 10-1000KV

The electrical transmission  towers meet ASTM Standards,GB/T standards and related standards .

Steel grades
Tower legs: Chinese standard Q345B, which equal to ASTM A572 Grade 50
Others members: Chinese Q235B, which equal to ASTM A36
Bolts: Chinese grade 6.8 and 8.8, which equal to ASTM A394

Dimension and tolerance for angle : GB/T1591-1994, Equal to EN 10056-1/2
Hot dip galvanization: GB/T 13912-2002, which similar to ASTM A 123

The welding :AWS D1.1 or CWB standard

If the thickness of the material not less than 5mm,The min average thickness of the galvanization of transmission

steel tower is more than 86um.

Type test and preshipment test is accepted .

If needed ,we even can supply an engineer for help installing the transmissions steel towers .

2.   Product capacity

We have 5 auto production line for electric transmission angle steel  towers Manufacturing,We can supply 3000 tons lattice steel tower

every month .Else we have enogh site for installing more production line if needed.

We also have plasma cutting machine ,14m bending machine and auto welding machines for pole towers .

​

​3.   Technical support

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 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

This the zinc thinckness requirement of ISO1461:

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.
