Aluminium Casement Door

❶High-Precision Extruded Profiles

One-step hot extrusion from national standard 6063-T6 tempered aluminum without thermal break cavities. Uniform wall thickness and multiple reinforcing ribs boost torsion and bending resistance. Electrostatic powder coating features strong adhesion against moisture and mild acid erosion. Matched die-cast frames and sashes minimize assembly tolerance for uniform installation and no sash misalignment after long-term use.

❷EPDM Continuous Sealing Gasket

One-piece extruded EPDM rubber forms a full perimeter seal without segmented joints to avoid air and water leakage. Foam inner layer fits gaps evenly under compression, resisting UV aging and low-temperature cracking. It is fixed via clamping slots instead of glue for easy single-strip replacement, maintaining steady airtight and dustproof performance with simple maintenance.

❸Double Tempered Insulated Glass

Standard 5mm+9A+5mm double tempered insulated glass with official 3C certification and finely ground edges for precise cutting. Dry air inside the cavity reduces noise transmission. Broken glass forms blunt particles to prevent cuts, and frosted, chameleon or patterned glass is optional for privacy partition scenarios.

❹Dedicated Glass Edge Gaskets

Co-extruded hard-soft gaskets lock into profile grooves and wrap glass edges to absorb vibration noise and seal tiny gaps against moisture intrusion. The material resists mold and water soaking in humid kitchen and bathroom areas, firmly fixing the glass panel without shaking or glue detachment.

❺CNC Bent Hollow Aluminum Spacer

CNC one-time bent aluminum spacer leaves only one joint sealed with butyl glue to cut moisture infiltration paths. The hollow structure resists bending and fits custom glass sizes far better than spliced spacers, fundamentally lowering fogging risk and suiting long-term service in rainy and humid southern regions.

❻High-Absorption Molecular Sieve Desiccant

4A molecular sieve pellets fill the spacer cavity to absorb free water molecules and residual vapor and stop condensation on inner glass surfaces. Filling quantity is proportioned to cavity volume to prevent premature failure or rattling, keeping the insulated glass dry and transparent without fogging or whitening.

❼45° Miter Glue Injection Joint Craft

45° miter joints are mechanically locked with stainless steel corner brackets then filled with structural glue via injection holes. Dual reinforcement of hardware and adhesive prevents joint gap and frame wobble under repeated opening force. Fully sealed splicing seams block rainwater seepage through corner gaps completely.

❽Anti-Rust Casement Opening Hardware

Thickened zinc alloy and stainless steel hinges with wear-resistant copper bushings bear standard door weight and stay smooth after tens of thousands of uses. Magnetic single-point lock and simple handle deliver easy operation. Passivated anti-rust treatment avoids jamming and oxidation in damp spaces, and separable spare parts cut overall maintenance cost effectively.
