The name is almost the same. The But the performance seems very different who can give me an explanation!
The full name of steel and plastic is a total of plastic and plastic, is the use of PVC crust micro-foam, and special-shaped steel lining co-extrusion method, and then by high-strength steel angle components into a door and window products. This high-tech patent products available, successfully overcome the ordinary steel doors and windows exist wind pressure performance, can not be high-rise building problems. At the same time also played the advantages of two kinds of steel materials - plastic micro-foam technology, excellent insulation, insulation, and high-strength type of special-shaped steel. Steel plastic materials also have no deformation, long life, environmental protection and other advantages.
Plastic composite window is PVC-U as the main component of the extrusion molding doors and windows materials, which is a building materials plastics.
PVC plastic doors and windows in the country is widely referred to as composite steel doors and windows, plastic doors and windows is based on polyvinyl chloride (PVC) resin as the main raw material, with a certain proportion of stabilizers, colorants, fillers, impact modifier, Ultraviolet absorbers (shielding agents) and other additives, the extrusion of the material.
??? Through the cutting, welding, etc. made of doors and windows of the frame fan, equipped with sealing tape, tops, hardware and other accessories made of doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the cavity need to add reinforced steel (steel Lining), this kind of doors and windows called plastic doors and windows.
