How to choose Window and Door Profile

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. Has quickly replaced plastic steel doors and windows, aluminum alloy doors and windows.

  1. The structure of Window and Door Profile

Window and Door Profile takes professional Western hard polyethylene (pvc) plastic profile as the main material, plus hardware components. The profile is a porous structure inner cavity, and the main cavity is lined with steel made of cold-rolled thick steel plate, which is used to improve the compressive strength of plastic steel doors and windows. The wall thickness of the profile should be above 2.5mm.

  2. Manufacturing of Window and Door Profile

Window and Door Profiles are generally produced in processing plants with special laser cutting and automatic welding machines for plastic steel doors and windows. They are produced by fully automatic assembly lines and automated technology, and the quality can be ensured.

  3. Common problems when purchasing Window and Door Profile.

 Window and Door Profile has been rapidly promoted and popularized in the engineering and construction industry with its excellent practical effects of environmental protection and energy saving. As a "low-carbon and environmentally friendly" product, it is increasingly favored by many customers. As everyone knows, environmental protection and energy saving do not mean environmental protection. Toxic plastic steel doors and windows not only pollute the environment, but also endanger health.

  1. Look at the packaging logo

  Look at the product name, national standard, company name, place of production, quality grade, etc. on the packaging design or label. If the basic content indicates whether it is complete, whether there is overlap or error in the overprinting of the text or pattern design. If the content of the packaging logo is incomplete, the text or graphic design and printing have overlaps or errors, it must be produced by a small and medium-sized profile company, and it is best not to purchase.

  2. Look at the color of the product

  The toxic Window and Door Profile is white in color. Although it is white, it gives people a "stupefied" visualization, that is, it is dark or white and blue, and the smoothness is obvious. After a period of application, it is affected by sulfur and sulfate in the air. Environmental pollution is gradually dark gray. The color of the non-toxic plastic steel profile is authentic, like ivory, with a smooth feeling, translucent, bright and gentle. It feels like it penetrates into it, and it will not appear dark gray when it is polluted by the sulfur and sulfate in the air.

  3. Look at the actual effect of the application

  Under the long-term effects of sunlight and heat, lead-salt plastic-steel doors and windows produce lead smoke on the surface, which can cause lead poisoning symptoms and lead environmental pollution. After lead enters the body, except a part of it is excreted in excrement and sweat, most of it is deposited in the spinal cord and melted into the night of blood, harming the software of the hematopoietic system, the central nervous system of the human brain, the genitourinary system and the male reproductive organs. Lead can also block blood production in the human body, causing iron deficiency anemia, causing headaches, dizziness, drowsiness, drowsiness, severe constipation and body aches. Application of organotin plastic steel doors and windows is not prone to the above symptoms.

  4. Look at the quality inspection confirmation

  After choosing Window and Door Profile, be sure to ask the agent for the product quality inspection certification. If the new test item in the certificate or test report is marked with lead content, it is confirmed that the product is a PVC profile.

  5. Look at the name of the product profile

  Toxic Window and Door Profile generally use high-quality and low-cost lead salt thickener as the key raw material. This type of raw material contains lead content, and the name is "PVC profile". Non-toxic plastic-steel doors and windows use non-toxic, zero-pollution, carbon alcohol organotin T-137 thickener, which is in compliance with environmental protection regulations, and the name is "VPVC profile".
