What color of the broken bridge aluminum windows best to see
First look at the bridge aluminum doors and windows of the profile. According to the national building materials standards, broken aluminum profiles should be used aluminum grades: 6063 or 6061, (these two materials for details please visit my website) these two alloys, with good stiffness, strength, corrosion resistance, the current Some of the illegal factory with industrial aluminum alloy or recycling recycled aluminum alloy extrusion profile, its strength, stiffness, corrosion resistance is much lower than the national standard, if the use of such materials profiles, will leave great hidden dangers. Second, look at the profile wall thickness. The national standard requirements of broken aluminum wall thickness should not be less than 1.4 mm, the current home improvement market, many products below the thickness of this standard, most of the non-fixed point small factory products. Then look at the insulation bar.
Whether the appearance of the profile is beautiful, mainly depends on the spraying material and quality, high-grade products generally use fluorocarbon spraying, home improvement and more use of powder coating, powder coating is divided into imported powder and domestic powder, national fixed-point production enterprises to use imported powder, Production, many small profile plant, simplified spraying process, no cadmium treatment equipment, spray quality can not be guaranteed. Pay attention to more than a few aspects, then you pick out the broken bridge aluminum doors and windows can be said to be the best.
GB66 nylon material must be used, because only PA66 nylon strength, temperature coefficient of deformation, mechanical properties and aluminum alloy is very close, and has good anti-aging ability, the use of PA66 nylon insulation to ensure that in the face of temperature changes, Mechanical deformation of the insulation bar and aluminum alloy does not produce a position between the wrong product to ensure the overall strength and durability. The current home improvement market, many manufacturers choose PVC plastic insulation products, because the PVC strength is much lower than the aluminum alloy and the deformation coefficient and aluminum alloy a lot of difference, anti-aging ability in general, so the use of such profiles will seriously affect the safety and life of doors and windows. There is the surface of the spray.
