UPVC door and window components

Window frame: This is the main part of UPVC doors and windows. It uses UPVC (polyvinyl chloride) as the main raw material, combined with auxiliary materials such as stabilizers, colorants, fillers, and ultraviolet absorbers, and is extruded into molded materials. The strength and stability of the window frame are very good, and it has excellent […]

Material and color: The main raw material of UPVC doors and windows is polyvinyl chloride (PVC-U) resin, which has good anti-aging performance, corrosion resistance and thermal insulation. The color of high-quality UPVC profiles should be white with a hint of green, and this color is not easy to age, discolor or deform under the wind […]

First of all, the main raw material of plastic steel doors and windows is polyvinyl chloride (UPVC) resin, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc. After a series of process treatments, such as extrusion molding, it is made into door and window frames and sashes by cutting, welding or screwing. Plastic […]

In today’s increasingly environmentally friendly, energy-saving and comfortable living environment, UPVC doors and windows, as a new type of building material, are gradually gaining favor. UPVC doors and windows are made of polyvinyl chloride (PVC-U) resin as the main raw material, through advanced production processes and formulas, combined with reinforced steel, hardware, glass, sealing materials, […]

Strength and pressure resistance: The greater the wall thickness of the profile, the higher its overall strength and pressure resistance. This means that thicker wall thickness can better resist deformation or cracking when subjected to external pressure or impact, ensuring the structural stability and safety of doors and windows. Sound insulation and thermal insulation performance: […]

Appearance and color: First, observe whether the surface of the UPVC profile is smooth and the color is uniform. High-quality UPVC profiles usually appear bluish-white or bluish-white. This color is not only beautiful, but also has good anti-aging properties. Avoid choosing profiles that are yellowish in color or have obvious color differences, as they may […]

Visual inspection: Observe the glossiness of doors and windows from a distance to see if there is any obvious color difference. Use a ruler to measure the dimensions of doors and windows and check for deformation. Touch the surface of the door and window at close range with your hands to check whether it is […]

Generally speaking, if the doors and windows are frequently opened and closed, or are in a relatively harsh environment (such as frequent contact with rain, sand, dust, etc.), then the frequency of maintenance should be higher. This ensures that the performance and appearance of the doors and windows are maintained in good condition. Specifically, every […]

First of all, pay attention to the quality and formula of UPVC profiles. High-quality UPVC profiles should have a multi-cavity design, thick walls, and anti-aging agents and anti-UV additives added to the formula. Such profiles can remain non-aging, discolored and deformed in the outdoor environment, thereby ensuring the long-term use of doors and windows. On […]

First, pay attention to the source and composition of UPVC materials. UPVC material itself is an environmentally friendly material. It is made from vinyl chloride monomer through polymerization reaction, and certain additives such as stabilizers, lubricants, etc. are added. Ensuring that materials come from reliable sources and do not contain harmful substances is the basis […]
