Explore our custom-engineered entry door solutions combining tempered impact-resistant glass, precision metal profiles, and heavy-duty structural hardware.
In contemporary residential estates and high-visibility commercial architectures, the front entry door serves as the defining structural nexus between exterior site physics and interior environmental comfort. Modern glass entry doors are no longer simple decorative timber frames holding single-pane clear glass; they have evolved into highly complex structural assemblies capable of managing extreme wind loads, severe thermal flux, acoustic infiltration, and forced-entry deterrence.
Unlike standard butt-hinged swing doors that transfer all gravity loads to vertical jambs, oversized glass pivot doors rely on heavy-duty top and bottom floor pivot pins. DERCHI engineers floor pivot hardware rated up to 800 kg (1,760 lbs), permitting glass leaves spanning up to 2,000 mm in width and 4,000 mm in height while maintaining fingertip operating forces under 15 Newtons.
By employing 6063-T5 high-tensile aluminum alloy profiles separated by Technoform® PA66-GF25 (25% glass fiber reinforced polyamide) thermal break strips, our glass entrance doors achieve U-values as low as 1.4 W/(m²·K). This thermal barrier eliminates condensation, minimizes thermal bridging, and preserves interior climate control across extreme microclimates.
Utilizing multi-cavity triple-sealed EPDM gasket loops combined with argon gas-filled double or triple Insulated Glass Units (IGUs), our exterior glass assemblies provide Sound Transmission Class (STC) ratings up to STC 42 and pressure resistance certified beyond 3,000 Pascals (Pa).

Situated in Foshan, Guangdong—the world’s premiere manufacturing capital for architectural aluminum and hardware—DERCHI delivers unparalleled cost-to-performance efficiency through total vertical supply chain integration.
DERCHI controls every step: raw 6063 aluminum billet extrusion, automated vertical powder coating lines (AkzoNobel® certified), fluorocarbon (PVDF) spraying, and anodizing lines. This eliminates sub-supplier markups and guarantees batch-to-batch color consistency.
Our 180,000 m² factory operates 5-axis CNC machining centers capable of milling hardware locks, hidden floor pivot pockets, and concealed door closer tracks with a tight machining tolerance of ±0.1 mm across profiles up to 6 meters in length.
Every glass leaf undergoes strict automated inspection: 1) Profile alloy hardness check, 2) Powder coating film thickness testing (≥60µm), 3) Glass double-seal dew-point verification, 4) Pre-assembly air/water chamber test, and 5) Fumigation-free plywood crate packaging.
From initial concept and architectural CAD shop drawings to containerized ocean shipment and on-site technical installation support.

Individual openings wrapped in protective EPE foam, packed into reinforced plywood crates with custom loading maps for rapid site sorting.
Architectural demand is rapidly shifting away from bulky, traditional door stiles toward ultra-slim profile profiles (vertical stiles as narrow as 20–30 mm). By embedding the aluminum structural sub-frame directly into surrounding masonry or curtain wall channels, DERCHI glass entry doors maximize daylight opening percentages while achieving a continuous glass-to-edge aesthetic.
Modern luxury doors are converting to concealed electromechanical multi-point locking systems. DERCHI integrates German-engineered dormakaba® and GU® motorized locks compatible with facial recognition, fingerprint readers, keypad access, and smart home automation systems (Control4, Crestron, KNX) for seamless hands-free entry.
Switchable privacy glass allows clear glass entry doors to instantly transform into opaque barriers at the touch of a button or mobile app command. By laminating Polymer Dispersed Liquid Crystal (PDLC) films inside tempered double-glazed units, DERCHI delivers dynamic privacy control without needing window blinds or drapes.
Emerging Next-Gen VIG technology replaces gas-filled insulating cavities with a high-vacuum chamber. This achieves center-of-glass U-values as low as 0.6 W/(m²·K) in a glass unit only 10 mm thick, drastically reducing leaf weight while exceeding triple-glazing thermal insulation standards.
Exposed to severe salt-spray environments and hurricane wind pressures, coastal luxury villas require marine-grade anodized or 30-micron PVDF-coated aluminum frames combined with SentryGlas® hurricane impact-resistant laminated glass to preserve ocean views safely.
High-traffic commercial entrances demand heavy-duty hydraulic floor pivots rated for over 1,000,000 operational cycles, integrated panic exit push bars, ADA-compliant low-profile thresholds, and auto-closing hydraulic controls.
Combining dark charcoal or matte black powder-coated aluminum French grid frames with energy-efficient Low-E tempered glass gives residential estates an industrial chic statement with modern thermal insulation performance.

In-depth answers to critical technical, structural, and logistical questions frequently asked by overseas architects, engineers, and project developers.
Standard DERCHI glass pivot systems accommodate leaf heights up to 4,000 mm (13.1 ft) and leaf widths up to 2,000 mm (6.5 ft). Utilizing heavy-duty hydraulic floor pivots engineered with internal thrust bearings, our systems comfortably support continuous leaf weights up to 800 kg (1,760 lbs). For extra-large openings exceeding these dimensions, our engineering department designs custom steel-core reinforced sub-frames with twin top-stay stabilizers.
Pivot doors naturally present sealing challenges at the top and bottom pivot axes. DERCHI solves this using drop-down automatic acoustic bottom seals (concealed mechanism that drops an EPDM gasket when the door shuts), dual continuous perimeter EPDM weatherstripping gaskets, and magnetic interlock sealing fins along vertical stiles. In lab testing under ASTM E331, our systems prevent water penetration at test pressures up to 450 Pa.
We supply a complete engineering compliance packet with every export shipment. This includes ISO 9001 quality system credentials, CE mark declaration of performance certificates (EN 14351-1), Australian AS2047 and AS1288 test reports issued by NATA-accredited laboratories, NFRC thermal performance calculation reports, and hurricane impact test summaries (TAS 201/202/203) for coastal U.S. projects.
Engineering CAD drafting and approval takes 3 to 7 working days. Once shop drawings are signed off and deposit confirmed, sample door orders ship in 15 to 20 days. Full container load bulk production (FCL) requires 25 to 35 calendar days depending on surface finish (PVDF coating or custom anodizing requires an extra 5 days). Ocean transit time varies from 14 days (US West Coast / Southeast Asia) to 30 days (Europe / US East Coast).
Yes. Our in-house tooling center develops custom extrusion dies within 12 to 15 days. If your project schedule mandates matching an existing architectural profile system (e.g., Reynaers, Schüco, or Cortizo), our technical team produces an equivalent shop drawing comparison matrix showing profile thickness, thermal break width, hardware compatibility, and cost savings achievable by sourcing direct from our Foshan factory.
Every glass door leaf is clad in PE protective film, fitted with heavy EPE foam corner shields, sealed inside moisture-proof poly-wrapping, and bolted vertically inside fumigation-free ISPM-15 compliant plywood crates. Crates feature integrated steel lifting lugs and base runners for forklift loading, ensuring zero glass breakage across thousands of sea freight shipments.
