Durable Decorative Bionic Telecommunication Tree Tower

Company introduction: 
  Hangzhou Debao Electromechanical Manufacturing Co,. Ltd was founded in 2003. It's a professional manufacturer in communication tower, electrical tower, galvanizing process and decorative antenna and so on. With 163.8 million RMB registered capital and 700 employees, Debao has become the largest hot-dip galvanizing production base around East China( total 780 tons production capacity). Also, it is the manufacturing base of Zhejiang University Chemistry Laboratory galvanizing products and enterprise credit AAA company with ISO certificate. 
  We have 10000 square meter office building and 46000 square meter workshop equipped with high-level production lines for communication tower and hot-dip galvanizing, which constitute a strong guarantee for the company's high operation efficiency. Per market demand, Debao launched a series of landscaped tower, bionic tower, decorative antenna, portable mobile base station, which have been widely used by operators now.

Qualification:
Business license, tax registration certificate and organization code certificate, quality management system, occupational health management system, environmental management system, enterprise credit AAA. 

Construction Process:
1.Raw material inspection 
Check steel specification, grade and heat number when coming, and then send sample to the laboratory for testing. Welding material needs re-rest of welding; Purchased tower attachments also need retest. Any non-conforming material should be avoided to enter into the production line.

2.Mark sample number
After sample plate and rod made, all the samples need to be approved by customers, then reviewed and marked number. Marked number with digital control, steel tower needs to retain head margin when cutting according to process requirement, diameter of both tube ends need the conformance with matching welding tube. The deviation is not more than ± 1.5D/1000, the total height deviation is no more than H/1500.

3.Rolling tube
After marked number and qualified, then turn to roll tube. To keep the ellipticity of the sheet plate, rolling on rolling machine where roller can move horizontally, then weld the connecting line and recheck. Visual inspection after rolling, the roundness should not exceed 3mm.

4.Welding
After tube bending, inspection and approval, it goes to automatic welding. Before welding, bevel angle is 25 degrees, also welding edge needs removing rust, burrs and dirt, electrode must be dried, coating drops or rust core are not allowed, and damp solder is also not allowed. Clean each welding line and inspect, then re-weld after clear defects. After welding slag and spatter need to be cleaned up. Select T-joints and 20% nearby welding line on main tower UT test to achieve GB11345-1989BII.

5.Flange installation
The flange needs automatic welding and UT test qualified. After installation and appearance inspection, inspect the angle dimension, so as to make sure the tower get installed smoothly.

6.Test assembly
Each section of the tower needs assembly test. The technical department will make a complete inspection, including the welding line mechanical property, the tower dimensions (length deviation, connection flatness and straightness, tower tube ovality, tube diameter deviation) must comply with requirement before turning to next stage.

7.Galvanizing 
After tower assembly test galvanizing will apply. Hot dip galvanizing coating thickness needs 86um <M<200um and anti-corrosion more than 30 years. Visual inspection after galvanizing, residual point will be not more than 1 cm2, smooth surface, no zinc tumor and thorns.
 
8.Inspection after galvanizing 
Test assembly again after galvanizing qualified, and the requirements are the same with previous test assembly. If there is deviation it needs correction, then turn to next stage.

9.Painting
Grinding zinc coating by sand blasting or abrasive paper to make the surface flatness and smoothness but not to damage zinc coating, then spay 6 layers painting to make sure the tower's service life.

Bionic Tower
Bionic tower is one kind of communication tower integrating into surroundings like buildings and plants. This tower is suitable for installing in scenic spots and squares. One more thing is bionic tower has good appearance, simulation and high durability. Following process and design are mainly applied:

Bionic tree
According to customer-supplied basic wind pressure, we will make a design against strength, stiffness, stability and wind(snow) loading capacity, then re-check. The main body is made from high strength fire-proofing material which is mixed with color glue and hemp, then combine to base tower, then use gardening bark to decorate the surface, which is conformed with basic principles of environics, structural mechanics and bionics etc.
Bionic branch
Branch is made of seamless tube and stainless steel wire. First, assembly weld to hollow frame; Second, bind stainless steel wire on the frame; then forming with glass fiber; Last, bolt to the main body.

Bionic leaf
About leaf, pine needle is the main model. The material is polymer nano which is wind resistance, sun blocking, fire proofing and not easily deformed.
