Glass Entry Door

Exterior Aluminum French Doors with Security Grid Design — Black Frame and Tempered Glass for Patio and Main Entrance (DERCHI Brand)

French grid elegance, light meets security — this DERCHI brand Exterior Aluminum French Doors with Security Grid Design innovatively integrates a security grid structure into the classic French door symmetrical double-opening design, dramatically enhancing security protection while preserving French doors' transparent daylighting advantage.

Black aluminum alloy frames clean and powerful, paired with large-area tempered glass panels enabling visual continuity between indoor and outdoor spaces with light flowing freely. The security grid constructed from precision aluminum profiles serves as both anti-theft barrier and decorative element — grid lines harmonizing with French door frame geometric proportions, presenting architectural aesthetics where modern meets classic.

Material & Craftsmanship

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

DERCHI Exterior Aluminum French Doors with Security Grid Design

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
