What Are The Profiles Of Aluminum Window Material?

Aluminum Alloy doors and windows, refers to the use of Aluminum Alloy extrusion for frame, frame, fan material doors and windows called Aluminum Alloy referred to as windows and doors, aluminum doors and windows. Aluminum alloy doors and windows, including aluminum alloy as the force bar (bear and transfer the weight and load of the rod) substrate and wood, plastic composite doors and windows, referred to as aluminum wood composite doors and windows, aluminum plastic composite doors and windows.

The quality of aluminum alloy doors and windows can be roughly judged from the selection of raw materials (aluminum profiles), aluminum surface treatment and internal processing quality, the price of aluminum alloy doors and windows, etc..

Look at the materials. Aluminum Alloy used aluminum doors and windows of high quality, thickness, strength and oxide film, shall conform to the relevant provisions of the national standard, the main force Aluminum Alloy window rod wall thickness should be 1.4 mm or more, the main force Aluminum Alloy door rod wall thickness should be more than 2 mm, the tensile strength per square metre 157 mm Newton, yield strength to reach 108 per square millimeter of Newton, film thickness should reach 10 micron. If it fails to meet the above standards, it is inferior aluminum alloy doors and windows, can not be used.

Two look at the processing. High quality aluminum alloy doors and windows, exquisite processing, installation stress, good sealing performance, switch freely. Aluminum Alloy doors and windows of inferior, choose aluminous profile series and specifications, processing by saw cutting instead of crudely made, milling, no installation required, poor sealing performance, the switch does not freely, not only air leaks and glass burst phenomenon, and encountered strong winds and force, easy to push and pull part or glass fall or drop destroy, wounding.

Three look at the price. In general, the quality of aluminum alloy doors and windows because of high production costs, the price is inferior to the quality of aluminum alloy doors and windows to be about 30% higher. Some aluminum alloy doors and windows made of 0.6-0.8 mm aluminum alloy with wall thickness, the tensile strength and yield strength are much lower than the relevant national standards, and the use is very unsafe. In addition, the processing of aluminum alloy doors and windows more self-employed, they do not understand the structural features and performance of aluminum alloy doors and windows. In order to reduce the cost of shoddy work, shoddy, the hidden trouble of the product is large, the general should not be used. The best choice of regular aluminum alloy doors and windows manufacturers products. Here is a special point: the thickness of the national standard profiles is 1.4mm, if suppliers choose 1.2mm or 1.0mm wall thickness and even thinner material, it is not up to standard products, please pay attention to when you buy.

Four, look at the material

There are 6 main aspects in material and material:

The thickness: Aluminum Alloy sliding window of 70 series, 90 series two, Aluminum Alloy housing interior sliding doors with 70 series. The number of aluminum alloy series indicates the number of millimeters in the thickness of the doorframe. Common aluminum alloy sliding window has 55 series, 60 series, 70 series, 90 series of four kinds. Selection should be based on the window size and the local wind pressure value is determined as shall be not less than 70 series Aluminum Alloy closed balcony sliding window.

The strength: tensile strength should be 157 per square millimeter of Newton, yield strength to reach 108 per square millimeter of Newton. When you buy it, you can bend the profile appropriately and let it go back to its original state.

3: the same color Aluminum Alloy profile color should be consistent, such as color, that is not to buy.

The flatness: check the Aluminum Alloy profile surface, should not sag or bulge.

The gloss: avoid buying Aluminum Alloy doors and windows opening on the surface of the bubble (white) and ash (black), crack, burr, profile leather and other obvious defects.

The oxidation degree of oxide film thickness should reach 10 micron. When choosing, light the surface of the profile to see if the oxide film on the surface can be wiped off.
