Window of model steel door heat preservation and heat insulation performance
Window of model steel door is cavity structure, good heat insulation performance, the heat transfer performance is very small, only l / 357 for steel, aluminum 1/250, visible plastic doors and Windows insulation, heat preservation effect is remarkable, especially for those modern buildings with heating air conditioning equipment. The relevant departments to investigate, i.e., use of window of model steel door than using wooden doors and Windows of the room winter indoor temperature can be high 4-5 degrees; The northern region has better effect to use double deck glass. Built according to the institute's institute test, single glass steel, aluminium window heat transfer coefficient of 64 w/M2K; Heat transfer coefficient of the single glass model steel window is around 47 w/M2K; Normal double glass steel, aluminium window heat transfer coefficient is 3. About 7 w/M2K; The double glass plastic steel window heat transfer coefficient is about 2. 5 w/M2K. Doors and Windows accounts for 30% of the area of the building envelope, the heat dissipating capacity 49%, therefore, model steel window has a good energy-saving efficiency.
The physical properties of window of model steel door
The physical properties of window of model steel door is mainly refers to: PVC the air permeability of window of model steel door (air tightness), rain water permeability, water tightness, wind resistance and heat preservation and sound insulation performance. Because window of model steel door profiles with unique chamber structure, and the welding process and into Windows and doors, in all the gaps when the installation of window of model steel door are equipped with doors and Windows sealing strip and wool top, therefore has the good physical properties.
The corrosion resistance of window of model steel door
Window of model steel door because of its unique formula and has good corrosion resistance, the second model steel window corrosion resistance depends on the use of hardware, normal circumstances hardware for metal products, industries and the corrosive environment, such as food, medicine, health, chemical industry and coastal areas, wet moist areas, and the use of anti-corrosion hardware (engineering plastics), which is 10 times that of window of model steel door service life.
Window of model steel door weatherability
Window of model steel door with special formula, raw material adding ultraviolet ray absorbent, and low-temperature impact resistance agent, thus improve the weatherability of window of model steel door. Long-term use in temperature climate environment, between a 30 ~ 70 degrees, sun, rain, change of dry, wet, no discoloration, metamorphism, such as aging, embrittlement phenomenon. Model steel window instance in Western Europe more than 30 years, its material intact.
Window of model steel door fire retardancy
Spontaneous combustion, combustion of window of model steel door, away from the fire, self-extinguishing, safe and reliable, conform to the requirements of the fire, the performance is more enlarged the scope of the use of window of model steel door.
Window of model steel door insulation performance
Window of model steel door with different profile excellent electrical insulation, conductive, high safety coefficient.
Window of model steel door tightness
Quality of window of model steel door is smooth and fine quality both inside and outside are consistent, that don't have to ask surface treatment, easy to machining, after cutting, welding, machining, doors and Windows product length, width and diagonal can within the plus or minus 2 mm, machining accuracy, the Angle of strength can reach more than 3000 n.
The sound insulation performance of window of model steel door
Mainly lies in the area accounted for about 80% of the glass of the sound insulation effect, some of the sound insulation of window of model steel door products on the market according to the principle of sonic resonance transmission and lotus root, adopt different glass composite structure, such as hollow glass model steel window, ordinary double deck glass, door window sound insulation effect. In terms of door and window structure, the use of high quality glue, plastic sealing parts, window of model steel door sealing effect is remarkable
