1. Introduction to home decoration aluminum alloy doors and windows

Home decoration aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles and fan materials. They are called aluminum alloy doors and windows. , referred to as aluminum doors and windows. Aluminum alloy doors and windows include doors and windows that use aluminum alloy as the force-bearing rod (a rod that bears and transmits its own weight and load) as the base material and wood and plastic composite doors and windows, referred to as aluminum-wood composite doors and windows, and aluminum-plastic composite doors and windows.

2. Characteristics of aluminum alloy doors and windows for home decoration

The profiles and glass styles of aluminum doors are divided into north and south. The main features of the north are thick aluminum and calm styles. The most representative one is the lattice style, and the most distinctive one among the lattice strips is Tange. The main features of the south are diverse aluminum shapes and lively styles. The most representative one is the patterned glass style, which includes patterned patterns, ice sculptures, shallow sculptures, crystal shells, etc. Among them, the iconic manufacturer is Guangzhou Xinbiao.

Aluminum alloy for home decoration - How to choose aluminum alloy doors and windows for home decoration

1. Size deviation

It is better to have the smallest size deviation of aluminum alloy door and window frames.

2. Aluminum alloy door and window components

The connection of aluminum alloy door and window components should be firm, and corrosion-resistant filling materials need to be used to make the connection parts sealed and waterproof.

3. Identification of logos

Regular manufacturers or manufacturers with production licenses will indicate the product logo on obvious parts of their aluminum alloy products, including: manufacturer name or trademark , product name, product model or mark, manufacturing date or serial number. There should be obvious words and signs on the packaging box such as "moisture-proof", "handle with care" and "up".

4. Surface quality

The surface quality of aluminum alloy doors and windows directly affects the decorative effect of the entire wall after installation. When checking the surface quality of doors and windows, you should pay attention to the following aspects: There should be no obvious damage to the decorative surface of doors and windows, which means that the protective film on the surface of doors and windows should not have signs of scratches or scratches. There should be no obvious color difference between the colored surfaces of adjacent components on doors and windows. There should be no aluminum chips, burrs, oil spots or other stains on the surface of doors and windows, and there should be no spilled adhesive at the assembly joints.

5. Look at the material

There are 6 main aspects for reference in terms of materials:

Flatness: Check the surface of the aluminum alloy profile, there should be no depressions or bulge.

Color: The color of the same aluminum alloy profile should be consistent. If the color difference is obvious, it is not suitable to purchase.

Oxidation degree: The thickness of the oxide film should reach 10 microns. When purchasing aluminum alloy doors and windows, you can lightly scratch the surface of the profile to see if the oxide film on the surface can be wiped off.

Glossiness: Aluminum alloy doors and windows should avoid purchasing profiles with open bubbles (white spots) and ash (black spots) on the surface, as well as obvious defects such as cracks, burrs, and peeling.

Strength: The tensile strength should reach 157 Newtons per square millimeter, and the yield strength should reach 108 Newtons per square millimeter. When purchasing aluminum alloy doors and windows, you can use your hands to bend the profile appropriately, and it should be able to return to its original shape after letting go.

Thickness: There are two types of aluminum alloy sliding doors, 70 series and 90 series. For aluminum alloy sliding doors in residential buildings, 70 series can be used. The series number indicates the thickness of the door frame in millimeters of construction dimensions. There are four types of aluminum alloy sliding windows: 55 series, 60 series, 70 series and 90 series. The series selection should be based on the size of the window opening and the local wind pressure value. Aluminum alloy sliding windows used for enclosed balconies should be no smaller than 70 series.
