  • How to identify whether plastic steel profile doors and windows are harmful?

    Window and Door Profile has the advantages of high air pressure and compression strength, good sealing and tightness, small infiltration of gas and precipitation, low thermal conductivity, thermal insulation, environmental protection and energy saving, sound insulation, noise reduction, thermal insulation, and resistance to embrittlement. It has quickly replaced plastic steel doors and windows, aluminum alloy doors and windows.

  • How to identify the quality of PVC Profiles?

    The high-quality profile has uniform size, reasonable internal cavity structure, soft color, smooth protective film, no bubbles, and the wall thickness of the extension part is generally 2mm;

  • What is the production process of uPVC Profile?

    As an energy-saving insulation material, uPVC Profile has inherent advantages. Non-metallic materials have poor heat transfer capacity, which promotes the low heat transfer coefficient of plastic steel profiles. It is very easy to achieve low thermal conductivity when making windows and doors. It is an ideal energy-saving insulation material.

  • How should uPVC Profile be cleaned and maintained?
