Steel-plastic co-extrusion doors and Windows have a strong ability to resist deformation

Steel-plastic co-extrusion doors and Windows are for the empty steel window put on a "quilted jacket", through the special assembly equipment will be a variety of rod balanced connection, the doors and Windows have a strong rigidity, and the empty steel lining is the use of galvanized cold tie steel rolling molding, with high dimensional stability and corrosion resistance.

(1) The sound insulation effect is obvious

Steel-plastic co-extruded profiles and 5+9A+5 hollow glass doors and Windows can reduce noise 33 decibels or more (test results), compared with other profiles, the middle of the surface of the steel lining and profile is 3-5mm hard microfoamed plastic, has a strong ability to absorb noise, its anti-noise performance is similar to wood, much higher than other metal materials, It can completely reduce the indoor noise to below 50 decibels, meet the requirements of ecological housing, and create a warm environment for residents to take quiet in the noise.

(2), sand-proof

The main way of sand into the living room is doors and Windows, people in northern areas suffer from the harm of sandstorm weather, poor sealing performance of doors and Windows can not block the invasion of sand is a common fact, but before the installation of almost all doors and Windows test results are qualified products, the lowest air tightness can also reach three levels, so why can not block the sand! In addition to the human factors of shoddy production, it is mainly caused by the deformation of doors and Windows in the process of use, and unreliable materials cause the deformation of doors and Windows, there are gaps, and sand and dust enter the gap. Steel-plastic co-extrusion doors and Windows are not deformed for a long time, so they can resist the intrusion of wind and sand, especially the door and window rods of the flat opening mode are rigid, and the sealing principle similar to that of the refrigerator has a more reliable long-term stable airtight effect.
