The development of steel profiles

From white to color: color profiles change the steel doors and windows in the past monotonous white, with the building as a whole with the perfect color. Color profiles market share rose rapidly, especially in some high-end residential area widely used.

Plastic doors and windows and plastic windows do not like?

According to the material plastic doors and windows can be divided into PVC plastic doors and windows and glass fiber reinforced plastic (FRP) doors and windows. The following are the same as the " 1, PVC plastic doors and windows 1) In all kinds of building windows, PVC plastic windows in saving energy production profiles, recycling of recycled materials and the use of energy consumption has a prominent advantage in the insulation and energy saving has excellent performance and low cost. The following are the same as the " 2) In order to increase the rigidity of the window, in the window frame, sash, the tread profile of the force bar, should be based on the strength of the wind pressure design and other requirements to determine what kind of reinforced steel. The following are the same as the " 3) Coextrusion of UPVC resin with colored polymethyl methacrylate (PMMA) or acrylonitrile-styrene-acrylate copolymer (ASA), as well as coating on white profiles, can be coated with a variety of textures and A variety of surface color decorative effect.
