Electrical transmission towers Voltage from 10-1000KV
The electrical transmission towers meet ASTM Standards,GB/T standards and related standards .
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 .
|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 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
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.
