Aluminum Forged Door Body: Aluminum forging process with aluminum alloy formed under high-temperature forging pressure — metal grain refined and densified, strength and toughness far exceeding ordinary cast aluminum or extruded profiles, door structure solid and durable with refined forging texture and quality on the surface.
Double Tempered Insulated Glass: Door face configured with double tempered glass + insulating cavity — tempered glass with high safety (shattering into granules without causing injury), insulating layer effectively blocking heat conduction, maintaining excellent thermal insulation while introducing natural light.
Polyurethane Foam Board Infilling: Door body interior filled with polyurethane foam board (PU Foam Board) — polyurethane being one of the most outstanding thermal insulation filling materials available, with extremely low thermal conductivity ensuring overall door insulation reaching high standards.
4mm-30mm Variable Profile Thickness: Profile thickness selectable from 4mm to 30mm — thin profiles for lightweight requirements, thick profiles meeting high security levels and extreme environment demands, flexibly adapting to different project performance standards.
Hidden Hinge System: Hinges completely concealed between door body and frame — door face appearance pure with zero exposed hardware, enhancing aesthetics while eliminating hinge-side security vulnerabilities.
Smart Lock / Key Lock Dual Options: Configurable with smart lock (fingerprint/password/card/APP remote) or traditional key lock — meeting different usage scenarios and security management requirements.
Waterproof Sealing Structure: Door body + frame + glass triple sealing design — ensuring zero water penetration during heavy rain, suitable for outdoor main entrance long-term use.

Frequently Asked Questions (FAQ)
What materials make the DERCHI aluminum forged door superior to standard doors?
The door body is crafted using a high-temperature aluminum forging process that refines and densifies metal grain, offering far greater strength than cast or extruded aluminum. It features double tempered insulated glass for safety and light, plus a solid polyurethane foam core for exceptional thermal insulation.
Can the profile thickness be customized for specific project requirements?
Yes, the profile thickness can be selected between 4mm and 30mm. Thinner profiles satisfy lightweight requirements, while thicker profiles are available for high security and extreme weather demands.
How does the door perform under severe weather and heavy rain?
The door features a triple-sealing structure across the body, frame, and glass, ensuring complete waterproof performance with zero water penetration even during heavy rain. Additionally, the aluminum alloy construction remains 100% rust-free for life.
What locking mechanism options are supported?
