Polycarbonate roofing tiles have been familiar with the domestic market for nearly a decade and currently have hundreds of brands for this material from dozens of brands. But how quality? The manufacturers and business people who used to say that good stuff also has less quality stuff; "The bad kind, just exposed to the rain about half a year has been sharp, opaque, take his hand to break it out like rice paper!"
To not be confused good - bad
Between a polycarbonate roofing product such that the origin and quality of the product is ambiguous, ambiguous, not checked by the authorities, it is a disorder. Businessmen usually publish this sign, the other is from Taiwan, Indonesia, Malaysia, China, Europe, America ... but in fact, most are made in China. There are foreign brands outsourcing in China to follow their own standards are good quality products, Chinese products good stuff also; But poor quality is also rampant because of ... immediate profit. There are domestic enterprises to China to order the brand name "tumultuous" and follow the standards ... as you like; Just stickers - announced ... x up is to sell, at any price ... to. Because of the lack of quality accreditation of any standard, the good mix of good - bad hard to know and selling price ... let loose - brass mixed up!
The professional producer on this type of roofing said that the plastic has many types and why polycarbonate must be chosen to make roof - light roofing. Because it has technical characteristics such as strength, high strength; Transparent, light transmission is close to the glass but light and hard to break. Because of such advantages, polycarbonate resins are 2-3 times higher than other types of resin. Consequently, low quality products use other plastics or scrap polycarbonate, so the quality is low - perishable, rapidly aging. So how can consumers choose the right polycarbonate roofing?

The best way is to choose from the units of origin, know the origin, publish the quality and they have warranty, they are responsible for the product they sell. That's how consumers protect themselves, choose wisely.
The unit supply polycarbonate sheet light poles of Germany best.
Roofing panels are suitable for use in public, industrial and residential buildings. From the decorative light roof, can bend to the dome ... to make signs, light boxes, billboards can use this polycarbonate panels. Prior to that market demand, E-power Engineering Co., Ltd imported polycarbonate roofing sheet from Germany. German polycarbonate light absorber against ultraviolet (UV) - anti-aging; There is also a layer of UV on the surface to protect all the polycarbonate roofs; Especially human and competitive price.

How to choose and note when installing German Polycarbonate Sheet
At present, in Vietnam market, Polycarbonate sheet (PC plate, Smart roof, light roof) are sold very widely with many different brands. And this product is widely applied in: glazed roof, door, sky, ...
Thanks to the advantages: Lightweight, durable, easy to install, and have high light transmission ... So more and more people are known and used as light material and decoration. However, in many cases these works do not have the quality and aesthetics as required after a period of use, such as: Sheet color turns yellow, there is water stagnation inside, moss and Dust accumulation, broken, broken ...
There are two main reasons for these fast-falling phenomena:
Quality of Polycarbonate Sheet:
On the market there are many different plates imported from different countries with different quality depending on the price of the plate. Generally for buildings, the life of polycarbonate sheets must be at least 5 to 10 years. However, there are many panels that have not been used outdoors for a long time. The main reason is the uneven and thin UV quality, and the high proportion of PC resin used in low plate production reduces the cost of plate production, leading to poor quality of the panels.

Incorrect installation and installation method:
Technical Department of E Power Engineering Co., Ltd offers a number of recommendations in design and construction of polycarbonate panels in lighted roofs to help you have aesthetic and Durable over time.
A, Polycarbonate sheet of Germany:
- Weather resistant from -40 degrees to + 115 degrees Celsius
- Light transmission: maximum 83%
- G Value from 0.86 - 0.12
- U Value up to 1.15 W / m2K (multi-layer structure) and 0.64 W / m2K (double structure)
- Capable of 200 times greater impact force than glass
- Maximum noise to 43 DB
- 10 year warranty from manufacturer
B. When designing a roof with a PC Panel: Requires roof slope> 5 degrees. With the slope of the roof, it will help drain the rain well and quickly, while helping to protect the roof by rainwater and reduce the roof lightening. The roof panels are covered by a sheet to help prevent dirt, water.
C. During installation: The panels are joined together by a U-bolt, tight fitting, do not screw on the sheet is not waterproof.
Popular application of polycarbonate panels
Polycarbonate sheet is extremely durable material. Polycarbonate has high impact resistance, sound resistance, fire resistance and durability for many years in extreme weather and weather conditions. Polycarbonate has many advantages over Glass (Glass) and Acrylic (PMMA), because it does not break, is lightweight, and has good UV resistance. Some of the common applications for polycarbonate sheets are described below:
Roof shade, roof cover:

Ultraviolet filtration capability is an important consideration when selecting roofing materials in the light receiving area. Polycarbonate panels have the ability to block up to 99.9% of ultraviolet light, while allowing light to pass through. These properties make the polycarbonate panels ideal for light-absorbing partitions such as: lighted roofs, awnings, glass roofs, sky wells, car roofs.
Roof for swimming pool:
The polycarbonate sheet is very suitable for swimming pool roofs, as it has the ability to protect against ultraviolet rays for swimmers inside. This makes the pool area safer for swimmers, and reduces the risk of sunburn and other complications from overexposure to sunlight. In addition, the weather resistance makes these roofs used for years without damage or aging.
Patio, skylight:
With its characteristic features: lightweight, ductile, easy to install and durable weather. Therefore, polycarbonate sheets are widely used in lighting items in civil engineering: roofs, skylights and drying yards in Vietnam.
