The quality of UPVC profiles is mainly determined by its design and manufacturing process. A good UPVC profile should be a reasonably designed multi-cavity body with thick walls. The formula contains anti-aging and anti-UV additives. From the outside, it should have a smooth surface and a bluish-white color. Color is also an important indicator of […]

The production method of plastic steel doors and windows is mainly through mechanical automation. Stabilizers, colorants, fillers, UV absorbers, etc. are added according to a certain proportion, and the molded materials are extruded, and then the door and window frames are made by cutting, welding or screwing. fan. In order to enhance the rigidity of […]

Stable chemical properties: UPVC has good chemical stability, can adapt to different environments and climate conditions, and is not susceptible to corrosion and aging. High mechanical strength: UPVC has high mechanical strength and can withstand greater pressure and tension, making it more durable. Strong corrosion resistance: UPVC has strong resistance to chemicals such as acids, […]

Good plastic steel doors and windows should have excellent physical properties and can adapt to various environments, such as places with strong winds, heavy rain, high heat, high cold, corrosive gases and other harsh environments. Plastic steel doors and windows are mainly made of polyvinyl chloride (PVC) resin as the main raw material, plus a […]

UPVC profile is a hard material made of polyvinyl chloride resin as raw material and added with additives such as plasticizers and stabilizers. It has the characteristics of light weight, easy processing, corrosion resistance, good insulation performance and low price. It is widely used in construction, automobile, shipbuilding, chemical industry and other fields. UPVC profiles […]

The specific gravity of UPVC material is only 1/5 of cast iron, which means that transportation and installation are easier and the cost is reduced. UPVC has excellent acid and alkali resistance, except for strong acids and bases or strong oxidants close to the saturation point. UPVC material cannot conduct electricity and is not corroded […]

Conduct acceptance according to design requirements and relevant regulations, check the allowable deviations in shape and size of finished UPVC doors and windows, and store them neatly indoors. The installation work should be carried out after indoor painting and outdoor painting, leveling, roughening and other wet work are completed. The joint position of the door […]

Polyvinyl chloride (UPVC) resin is used as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, UV absorbers, etc., and is extruded into molded materials. Door and window frames are made by cutting, welding or screwing, and equipped with sealing strips, tops, hardware, etc. In order to enhance the rigidity of the […]
