Plastic-steel windows are a form of window that has been actively promoted by the state in the mid-1990s after wood, iron and aluminum alloy windows. Due to its lower price and better performance, it is still widely used. The frame of this window is made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., and extruded materials; it is the most commonly used window category for modern buildings.

Plastic -steel doors and windows are based on polyvinyl chloride resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., after extrusion molding, and then The door and window frame fan is made by cutting, welding or screwing, and is equipped with sealing strips, tops, hardware, etc., and at the same time, to strengthen the rigidity of the profile, the steel lining needs to be added in the cavity of the profile exceeding a certain length (enhanced Reinforcement), the portal window made in this way, called plastic steel doors and windows. Therefore, the price of plastic steel window is generally slightly more expensive than other types of plastic steel windows. In addition, the process of making plastic steel doors and windows also has its own unique process. The construction scheme of plastic steel window is also quite different from other.

1.The specifications and models of plastic-steel windows should meet the design requirements. The quality and mechanical properties of the windows conform to the requirements of the current national standards, and have a factory certificate.

2. The three basic physical properties of the window against wind pressure, air infiltration and rainwater infiltration should meet the requirements and design requirements of the three performance classifications in the current national standards, and the quality inspection report of this level is attached.Plastic steel window pulleys and slidesThe engineering design has no specific requirements for insulation and sound insulation performance.

3. The models, specifications, performance and requirements of hardware, fasteners, reinforced steel and metal plate used in the window shall comply with the relevant provisions of the current national standards.

4, the variety, specifications and quality of glass should comply with the provisions of the current national product standards, and have product certification. Tempered glass must be used for a single piece of glass greater than 1.5 m2.

5, window and hole sealant should have elasticity and adhesion.
