The wall thickness of bridge broken aluminum doors and windows directly affects the quality of bridge broken aluminum doors and windows. Different wall thickness of bridge broken aluminum has different prices, so we must consult clearly when selecting bridge broken aluminum. The common wall thickness is 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, etc.
Why do different wall thickness of the broken bridge aluminum doors and windows have different prices? The main reason is that the bridge broken aluminum is aluminum profiles, and the material is calculated by tons. One ton of the same aluminum rod can produce more thin bridge broken aluminum profiles, and the production of thick bridge broken aluminum profiles is less. This will increase the price of bridge broken aluminum raw materials from the cost.
Broken bridge aluminum doors and windows miscellaneous brand is generally between 1.0 mm-1.2 mm, if the domestic famous brand of broken bridge aluminum, then the production of bridge broken aluminum doors and windows are in accordance with the national standard requirements, the lowest is 1.4mm wall thickness, and the better bridge broken aluminum doors and windows 70 series is 1.8mm wall thickness.
When we choose the broken bridge aluminum doors and windows, we need to know not only the model of the broken bridge aluminum, but also the wall thickness, because some of the broken bridge aluminum models meet your requirements. For example, you want to break the bridge aluminum 70 series, but the price of the broken bridge aluminum 70 series with the wall thickness of 1.4mm and the wall thickness of 1.8mm is very different.
Broken bridge aluminum purchase, another is to see the heat insulation strip. According to the national standard, PA66 nylon material must be used, because only the strength, temperature deformation coefficient and mechanical properties of PA66 nylon are very close to those of aluminum alloy, and have good anti-aging ability, the use of PA66 nylon thermal insulation strip can ensure that there is no dislocation between the insulation strip and the aluminum alloy in case of temperature change and mechanical deformation, so as to ensure the overall strength and durability of the product. At present, many manufacturers in the home decoration market choose PVC plastic heat insulation strip products. Because the strength of PVC is far lower than that of aluminum alloy, the deformation coefficient is much different from that of aluminum alloy, and the anti-aging ability is general, so the use of this type of material will seriously affect the safety and service life of doors and windows.
If you don't know how to check the heat insulation strip, you'd better choose the well-known bridge breaking aluminum brand. The regular well-known bridge breaking aluminum brand adopts PA66 heat insulation strip, which can ensure the quality and heat insulation effect of bridge broken aluminum doors and windows from the material.
