High Voltage DC Power Transmission Line Tower Steel Structure
1. Production decription
Features:
- Various towers are all lattice structure. Bars are composed of
single equilateral angle steel or combination of angle steel.
- The materials are generally Q235B, Q355B(16Mn) and Q420 The
connection between the bars are crude bolts.
- Hot dip galvanized anti-corrosion. Very convenient for
transportation and construction erection.
- To the towers, which vertical distance from horizontal ground to
first-floor crossarm hang point is below 60 meters, we set foot
nails on one of main legs to facilitate the construction workers to
climb onto the tower for operation.

There are four major categories of transmission towers:suspension
tower , terminal tower , tension tower , and transposition tower .
Some transmission towers combine these basic functions.
2. Product capacity
We have 5 auto production line for electric angle steel towers
Manufacturing,We can supply 3000 tons angle 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 thinkness inspection
5. Trial assembly
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.
