Quality standard for aluminum alloy doors and Windows (I)

Quality of window of aluminium alloy door can be judged roughly from raw material (aluminium profile) the respect such as the price of window of window of select material, aluminium material surface processing and interior processing quality, aluminium alloy. Below Changshu City Li 'an aluminum alloy doors and Windows company xiaobian first take you to understand two points in detail -- with materials, processing and price!

First, look at the material.

Aluminum used in the aluminum alloy doors and Windows, ply, intensity and oxidation film, etc., shall comply with the relevant standards, aluminium alloy window main stress bar wall thickness should be in 1.4 millimeter above, aluminium alloy door main stress bar wall thickness should be in 2.0 millimeter above, tensile strength of millimeter of every square metre 157 Newton, succumb intensity should achieve every square millimeter 108 Newton, The oxide film thickness should reach 10 microns. If not up to the above standards, is inferior aluminum alloy doors and Windows, can not be used.

Two, look at the processing.

Aluminum alloy doors and Windows, fine processing, exquisite installation, good sealing performance, switch from such as. Inferior aluminium alloy door, choose aluminous profile series and norms blindly, processed and manufactured in order to curium cut replaces mill processing, not according to the requirements for installation, sealed performance is poor, switch does not freely, not only rain of air leak leakage and occurrence glass glass cracking phenomenon, and encounter blast and outside force, blow push-pull part or glass easily fall or touch fall, destroy content cuts.

Three, look at the price.

Under normal circumstances, aluminium alloy door window because production cost is high, the price than inferior aluminium alloy door window wants tall 30% or so. Some have wall thickness only 0.6-0.8 mm aluminum profile aluminum door window that makes, tensile strength and yield strength are set under concerned standard greatly, use very unsafe. In addition, the self-employed door of processing aluminium alloy door is more, they do not know the structural characteristic of aluminium alloy door window and its performance. In order to reduce the cost of jerry-building, shoddy, the hidden danger of the product is larger, generally should not be used. Choose the product of manufacturer of normal aluminium alloy door window. Here to note in particular: the standard profile thickness is 1.4mm, if the supplier chooses 1.2mm or 1.0mm wall thickness or thinner materials, are substandard products, please pay attention to the purchase.
