Plastic steel windows/ UPVC windows

Plastic steel window (UPVC window) ,including Ordinary white plastic steel windows, two-color coextruded steel windows, full color plastic steel windows, coated plastic steel windows.

The advantages of plastic steel windows are good sound insulation, heat insulation, fire resistance, air tightness, water tightness, corrosion resistance, insulation and so on. The disadvantage is ,after all, it is PVC plastic profile,after a long time, the surface shall turn yellow and the shape of the window shall be deformed. The service life will be 20-30 years.

The price ratio of plastic steel windows is the main reason of its hot sales.

Plastic steel doors and windows’ main raw material is Poly Vinyl Chloride (PVC) resin,plus a certain proportion of stabilizer, coloring agent, filling agent, ultraviolet absorbent and so on, through extrusion into profiles, and then through cutting, welding or screw connection to make doors and windows frame fan,fitted sealant strips, hair Bar, hardware and so on,at the same time to enhance the rigidity of the profile, steel lining (reinforcement) is needed in the profile cavity if more than a certain length, thus this kind of doors and windows are called plastic steel doors and windows. therefore, the price of the plastic steel window is a little more expensive than the other types of plastic steel windows. In addition, the process of making the plastic steel doors and windows has its own process, and the construction scheme of the plastic steel window is also quite different from others.

The plastic steel doors and windows without steel liner are only considered as plastic doors and windows.,the real plastic steel windows are with the steel lining added. The anti wind pressure performance of the plastic steel doors and windows mainly depends on the specifications of the reinforcement of the steel lining in the cavity.The larger the section size of the lining steel, the greater the thickness, then the greater the moment of inertia, and the better the anti wind pressure performance.The steel lining cavity is larger and can be loaded with larger steel lining. Under the same thickness of steel lining, the moment of inertia is relatively larger, so it has relatively better wind resistance performance, which makes it suitable for use in high-rise buildings, and is not easy in damage and deformation.

The industry standard "non plasticized PVC plastic window" JG/T140-2005 (door standard is JGT180-2005), the third pages sixth section  6.2.1 ,there is regulation "the minimum wall thickness of reinforced steel should not be less than 1.5mm".      Our company mostly adopt window thickness =1.5mm, wall thickness of doors =2.0mm, cold galvanizing treatment on the surface of steel lining
