Profile series: 55/60/70/80 series (numbers represent profile section width, the larger the series, the stronger the insulation performance).

2. Corner code and corner piece assembly

Corner code: made of aluminum alloy material, with surface galvanized or sprayed treatment, used for 45 ° splicing of profiles.

Corner piece: made of stainless steel material, with a thickness of ≥ 1.5mm, enhancing the strength of the corner (wind pressure resistance performance ≥ 5000Pa).

2、 Sealing system (key for waterproofing and dust prevention)

1. Sealing strip

Material: Ethylene propylene diene monomer (EPDM), weather resistance ≥ 10 years, Shore hardness 60 ± 5.

Type:

Equal pressure adhesive strip: used between window sashes and window frames to form an equal pressure chamber and reduce rainwater infiltration.

Glass sealing strip: Double channel sealing design, with dust-proof outer layer and waterproof inner layer.

2. Sealed wool strip

Material: Silicified polypropylene fiber, with strong anti-aging performance, used for dust prevention at the bottom of window sash.

Specification: Width ≥ 6mm, height ≥ 4mm.

3、 Hardware System (Function Implementation Core)

1. Handle and transmission

Handle: made of zinc alloy or stainless steel material, surface electroplated, with opening and closing times ≥ 50000 times.

Transmission: Made of stainless steel material, with a connecting rod diameter of ≥ 8mm, ensuring synchronous opening of the window sash.

2. Hinges and sliding braces

External hinge: made of 304 stainless steel, with a load-bearing capacity of ≥ 80kg and an opening angle of 90 °.

Internal opening and sliding support: Concealed design, with a load-bearing capacity of ≥ 100kg, supporting ventilation with an inward tilt of 15 °.

3. Lock point and lock seat

Mushroom head locking point: diameter ≥ 12mm, enhances anti-theft performance (meets RC2 level standard).

Lock seat: made of zinc alloy material, galvanized on the surface, with a clearance of ≤ 0.5mm when matched with the lock point.

4、 Glass system (thermal insulation and sound insulation core)

1. Hollow glass

Structure: 5mm+12A+5mm (double-layer hollow), or 5mm+12Ar+5mm+12A+5mm (three-layer hollow).

Spacer strip: Warm edge spacer strip (such as TPS flexible seal) to reduce the risk of condensation at the edge of the glass.

Inflation: Optional argon gas filling (K value reduced by 0.3-0.5W/m ² · K).

2. Glass pressure strip

Material: Aluminum alloy or PVC, matching the color of the profile, with a gap of ≤ 0.3mm after installation.

5、 Auxiliary accessories (installation and functional enhancement)

1. Fixed parts and connectors

Expansion bolt: M8 × 80 stainless steel material, used for fixing window frames and walls.

Connecting piece: made of aluminum alloy material, with a thickness of ≥ 2mm, used for connecting window frames and sub frames.

Waterproof and insulation materials

2. Foam adhesive: made of polyurethane material, with a thermal conductivity of ≤ 0.024W/m · K, filling the gap between the window frame and the wall.

Waterproof breathable membrane: PE microporous membrane, with a water vapor transmission rate of ≥ 500g/m ² · 24h, to prevent rainwater infiltration.

3. Decorative components

Corner protector: Made of PVC material, it prevents the profile from being bumped during transportation.

Decorative cover: made of aluminum alloy material, covering screw holes to enhance aesthetics.
