110kv Angle Steel Tower
Tower description
Transmission tower is a tall structure, usually a steel lattice tower, use to support an overhead power line. We render these products with the help of
diligent workforce having vast experience in this field. We go through detailed line survey, route maps, spotting of towers, chart structure and technique document while providing these products.
Our product covers the 11kV to 500kV while include different tower type for example suspension tower, strain tower, angle tower, end tower etc.
Additionally, we still have a vast designed tower type and design service to be offered while if clients have no drawings.

TESTS
X.Y. Tower has a very strict test protocol to ensure all products we fabricate is quality. The following process is applied in our production flow.
Sections and Plates
1. Chemical composition (Ladle Analysis)
2. Tensile Tests
3. Bend Tests
Nuts and Bolts
1. Proof Load test
2. Ultimate Tensile Strength test
3. Ultimate tensile strength test under eccentric load
4. Cold bend test
5. Hardness test
6. Galvanizing test
All the test data are recorded and will be reported to the management. If any flaws are found, the product will be repaired or scraped directly.
Hot-dip galvanizing
Quality of Hot-dip galvanizing is one of our strength, Our CEO Mr. Lee is an expert in this field with reputation in Western-China. Our team has vast experience in HDG process and especially good at handling the tower in high corrosion areas.
Galvanized standard: ISO:1461-2002.

Package and shipment
Every piece of our products is coded according to the detail drawing. Every code will be put a steel seal on each piece. According to the code, clients will clearly know a single piece belong to which type and segments.
All the pieces are properly numbered and packaged through the drawing which could guarantee no single piece missing and easily to be installed.
Shipment
Normally, the product will ready in 20 working days after deposit. Then the product will take 5-7 working days to arrive at Shanghai Port.
For some countries or regions, like Central Asia, Myanmar, Vietnam etc., China-Europe freight train and carriage by land may be two better options of transportation.
After-sales Service
An after-sales manager will be assigned to do the after-sales service for clients.
We will provide package instructions and installation drawing to clients which can help construction team to install towers.
If construction team meet any problem when they assembly the tower, we would like offer any help we can. Including we can give guidance via video connection or other methods.
For some projects, we will prepare some spare pieces of products to clients for free in order to prevent some unforeseen circumstances.
The warranty time of the product is 50 years.
