Black Aluminum Alloy Frame: Premium aluminum alloy profiles with anodized or powder-coated classic black surface — black frame lines clean and powerful, forming striking contrast with various exterior wall colours, highlighting door architectural presence and modern character.
Tempered Glass Panels: Door face configured with large-area tempered glass — tempered glass 3-5x stronger than ordinary glass, shattering into small granules without causing injury, ensuring safety while achieving maximum natural daylighting and visual transparency.
Security Grid Structure: Glass areas configured with aluminum alloy security grid — grid profiles structurally engineered with precisely designed spacing and thickness, effectively preventing human passage (anti-theft) without excessively blocking sightlines or light.
French Door Symmetrical Design: Classic French Door double-opening symmetrical structure — left and right door panels with equal proportions and symmetrically echoing grids, embodying French architecture's order aesthetics and elegant proportions.
Aluminum Alloy Weather Resistance: Aluminum naturally rust-free — black surface treatment UV-resistant and weather-proof, no fading or deformation from long-term outdoor patio use, maintenance-free with long lifespan.
Sealing System Design: Professional weatherstripping between frame and glass — ensuring waterproof and windproof performance, effectively blocking rainwater and sand intrusion in patio installation environments.

Yes. Aluminum alloy is naturally rust-free, and our UV-resistant black surface finishing prevents fading and corrosion. Equipped with professional weatherstripping, these doors effectively seal out wind and rainwater.
Absolutely. While standard black frame is our classic design, all door dimensions, grid patterns, colors, and glass specifications can be fully customized to fit your specific architectural openings.
We utilize premium safety tempered glass which is 3 to 5 times stronger than standard glass. In the unlikely event of breakage, it shatters into small blunt granules to prevent injury.
Factory custom production typically takes between 15 to 25 days following design confirmation. Delivery times vary by location, and all items are shipped with protective export packaging.
These doors are essentially maintenance-free. We recommend wiping the aluminum frame quarterly with a neutral cleaner, cleaning the glass with standard glass cleaner, and lubricating the hardware hinges every 6 months.
