Bowa was Choi Yong-called full-wave modified asphalt plant fiber tile, it is by single fibreboard plant at a high temperature dipping modified bitumen from its color technology is the use of patented coloring process, and thermosetting resins used solid color, color penetration The thickness of material to ensure that in-Choi Yong-Bowa lasting such as the new color.
In this complex process made of a Wing-color wave watts flexible, durable and widespread use, materials and colors more than the traditional tiles Jingde Zhu stood the test of time.
Choi Yong-Bowa in the classification
Choi Yong-in-tile Bowa There are currently three types: Wing-a-ling, the United States in the Nanjing-based, Luoma Ning type. 
  



  Wing-ling-a standard size (length x width): 2000 (mm) x 950 (mm)
Wave height and wave distance: 37mm, 95mm
Wave: 10, and other wave
 
  The United States in the Nanjing-based standard-size (length x width): 2000 (mm) x 1055 (mm)
Wave height and wave distance: 24mm, 49/97mm
Wave: 15 wavelet
 
  Luoma Ning-standard dimensions (length x width): 2000 (mm) x 1055 (mm)
Wave height and wave from: 29/24mm, 48/96mm
Wave: seven big wave / 8 wavelet
 

Standard Color:

Choi Yong-in-the characteristics of Bowa
Light: every square foot of about 3 kg.
Aesthetics: a variety of colors and difficult to fade, strong sense of three-dimensional.
Superior performance: do not waterproof layer, insulating layer optional, and has excellent noise and anti-corrosion properties.
Construction simple: can easily cut the required size, with a nail in the fixed-PURLIN, PURLIN of steel or concrete roof.
Durable: life for more than 30 years.
 
Quality assurance
Choi Yong-Bowa in the housing construction by the French Technical Center CSTB (No.5/04-1779) that the communications technology products, including China and adopted the JC503-92, GB8040 ~ 8042-87, the various international Quality standard test. Bowa was Choi Yong-Ning of China easily passed the test centre of the chemical building materials 2,000 hours of artificial aging test (the national standard of 250 hours).
