Himfr.com Reveals the Reasons behind the Varying Prices of Plastic-coated Steel Doors and Windows

Posted on: Monday, 24 August 2009, 09:00 CDT

BEIJING, Aug. 24 /PRNewswire-Asia/ -- Himfr.com, one of China's leading B2B search platforms with more than 30 B2B industry websites to its name, reveals why the prices of plastic-coated steel doors and windows vary so greatly.

Plastic-coated steel doors and windows have become some of the best-selling construction materials. Although people have long been aware that plastic-coated steel doors and windows are more durable as well as more heat- and noise-resistant than other materials, plastic-coated steel doors and windows vary greatly in terms of performance and price. The cheaper options average around 100 yuan per square meter, and the expensive options are in the thousands of yuan. What causes such a big difference in price? Himfr experts will reveal this secret.

Compared with other door and window materials, plastic-coated steel doors and windows are 30% more effective in terms of noise insulation and noise reduction. If combined with double-insulated glass, the effect will be even better. The superior thermal insulation, sound insulation, resistance to aging, anti-erosion and airtight qualities of plastic-coated steel doors and windows are not only due to their material composition, but are also achieved through plastic-coated steel doors and windows' structure, processing technology and hardware components such as glass, sealing tape and so on. The different requirements for different types of doors and windows also have a considerable impact on price and quality.

Varying material composition is the main reason behind price differences. The main material used in plastic-coated steel doors and windows is a special formula of rigid poly-vinyl chloride, or PVC. Although the PVC used may be the same, resins and additives used during the manufacturing process may not be. These differences are not evident to the naked eye, but will impact the material's anti-ultraviolet and anti-aging functions. In addition, the material structure will also directly affect price and quality. Steel liners enhance the strength of plastic-coated steel doors and windows, providing impact resistance and anti-pressure capabilities.

The quality of steel liners in plastic-coated steel doors and windows varies greatly. High-grade steel liners used in galvanized steel are approximately 2.5 mm thick, while some small-scale production operations only use steel and anti-rust lacquer, which is relatively thin at about 1.5 mm. Use of the latter kind of liner in the corners of plastic-coated steel doors and windows by manufacturers in an effort to conserve steel liner is considered jerry-building. This difference is also not visible to the naked eye, but will impact the quality of the product.

Differences in processing technology will affect the quality of plastic-coated steel doors and windows. In particular the door, if not welded well, will fracture under a certain degree of pressure. Therefore, when buying plastic-coated steel doors and windows, one should pay attention to whether the corners are welded by hand. If welded manually, the thermal insulation and anti-pressure properties will not be up to standard.

Hardware fittings and other materials used come in different grades. As far as hardware fittings go, the prices and quality of imported brands tend to be higher. Of course, in order to cut costs, some small manufacturers may reduce spending on parts. For example, they may use a single layer of materials instead of applying double-sided locking hardware fittings. In addition, other materials used, such as glass and sealing tape, also affect the quality. Products built with professionally-manufactured sealing tape are very durable and resistant to erosion, while low-quality products cannot withstand high temperatures and ultraviolet radiation, and under such conditions easily change colors and show age.

Himfr 's experts suggest consumers choose a reliable brand that can guarantee product quality. Furthermore, reliable brands have near-perfect after-sales service and good track records for success, which is worth considering.
