We have been making every effort to provide high quality TV Antenna
Tower. On one hand, auto-cad and prototype software are applied
inprototype to ensure the precision of workshop drawings. A sample
tower will be made for inspection before mass production. In mass
production,we adopt advanced management to monitor the precise
manufacturing progress of towers, to ensure each piece qualified.
On the other hand, we equip our mechanical and chemical Labs with
modern facilities, so that many routine experiments, such as
Bearing Stress, Preece Test, Stripping Test and Five Elements
Analysis etc, can be carried out smoothly, so as to ensure that our
finish products meet with the ASTM or ISO standards.
The following is the quick details of our factory:
1. Capacity
| Maximum Production Capacity of Steel Tower per annum | 100,000 TON per annum |
| Maximum Capacity of Galvanizing Plant per annum | 100,000 TON per annum |
2. Test
| Factory test | Tensile test,Elements analysis, Sharpy test(impact test), Cold
Bending, Preece test, Hammer tes |
3. Quality control
100% inspection: Each member will be checked by our QC team to
ensure all members are qualified before delivery.
4. Package
Set-wisely packing or member-wisely packing as per client's
requirements.
Tower members: One steel tower is separated into several bundles.
Bolts: Packing material is robust nylon bag or steel drum.
5. Experiences
Our products have been exported to more than 40 countries, such as
Finland, Macedonia, Colombia, Venezuela, Chile, Cuba, Myanmar,
South Korea, Kazakhstan, Pakistan, Philippines, India, Indonesia,
Ethiopia, Sudan, Rwanda, Ghana, Benin, Nigeria, South Africa, UAE
