Door and window encyclopedia: 6 indicators of aluminum alloy door and window materials

1. Thickness: There are 70 series and 90 series of aluminum alloy sliding doors. The 70 series of aluminum sliding doors in the house can be used. The number of series indicates the number of millimeters of the thickness of the door frame. Aluminum alloy sliding windows are available in 55 series, 60 series, 70 series and 90 series. The selection of the series should be based on the size of the window and the local wind pressure. The aluminum alloy sliding window used as a closed balcony should be no less than the 70 series.

2. Strength: The tensile strength should be 157 Newtons per square meter and the yield strength should be 108 Newtons per square millimeter. When purchasing, you can use your hand to bend the profile moderately, and you should be able to recover after loosening your hand.

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

4. Flatness: Check the surface of the aluminum alloy profile without any depression or bulging.

5. Gloss: Aluminum alloy doors and windows avoid the appearance of open air bubbles (white spots) and ash (black spots), as well as cracks, burrs, peeling and other obvious defects.

6. Oxidation degree: The thickness of the oxide film should reach 10 microns. When you purchase, you can scratch the surface of the profile to see if the oxide film on the surface can be wiped off.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Specification

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
