The 30 x 80 exterior door is a custom‑manufactured aluminum entry system built for B2B projects. It combines a thermally broken profile, heavy‑duty locking, and broad configuration choices to meet demanding commercial and residential specs.
- Made to order in 30" x 80" (762 x 2032 mm) with adaptable rough opening allowances for straightforward installation.
- Multi‑point locks and reinforced frames raise security at primary and secondary entrances.
- Certification packs (NFRC, CE, AS2047, etc.) can be supplied with the project‑specific door configuration.

Product Details
For buyers specifying this door size, DERCHI’s system starts with a polyamide thermal break that separates the inner and outer aluminum profiles, limiting conductive heat loss. Front panels use two sheets of aviation‑grade aluminum, each 4 mm thick, with a 12 mm oriented strand board back panel and a polyurethane foam core. The lower section is reinforced with 304 stainless steel and a 1.8 mm magnesium alloy steel sheet, creating a rigid assembly resistant to warping and forced entry.
Compression is handled by multi‑layer EPDM gaskets; together with the thermally‑broken sill, they control air and water ingress. Every door is fabricated to order, so hardware choices—hidden hinges with anti‑pry technology, smart locks, closers—can be selected without compromise. Architects and contractors gain a durable front‑entrance solution that supports site‑specific egress arrangements and matches the building’s finish palette.
Product Features
Thermal isolation: Polyamide bars interrupt direct metal‑to‑metal contact, slowing heat flow and helping projects approach energy‑code targets without oversized frames.
Weather‑tight sealing: Three EPDM gaskets form a compression barrier against wind, dust, and rain, keeping interior finishes dry across seasons.
Load‑bearing hinge: The 304 stainless steel hinge has been endurance‑tested to 100,000 cycles and holds over 150 kg, so it stays smooth even in lobbies and corridors.
Impact‑resistant shell: Aviation aluminum panels and the magnesium‑alloy‑reinforced lower gear raise surface strength for busy building entryways.
Configurable locking: Combine multi‑point locks, super C‑class cylinders, or fingerprint‑based access to match site security plans.
Finish and glass freedom: Wood‑grain foil, RAL powdercoat, decorative or low‑E glass—all specifiable to align with architectural intent.

Customizable Styles
Size adaptability: While nominal dimensions are 30 x 80 inches, the custom door can be fine‑tuned to match as‑built openings or blueprint dimensions.
Surface finish: Realistic wood textures, textured powder coatings, and any RAL color maintain consistent branding or design language across a project.
Glazing: Clear, frosted, tinted, or low‑E double‑glazed units can be installed; thermal performance varies with the glass specification.
Swing direction: Inswing or outswing, left‑ or right‑handed, set to suit circulation plans and local egress requirements.
Sill and threshold: Thermally broken sills and adjustable thresholds are available to improve weather resistance and meet accessibility needs.
Hardware Accessories
304 stainless steel handle: Resists corrosion in coastal or high‑humidity environments and stays clean with minimal upkeep.
Zinc alloy handle: Offers diverse profiles and finishes to complement the door panel’s look without sacrificing durability.
Smart lock: Fingerprint, password, and IC card access eliminate physical keys and allow usage tracking—useful for hotels, offices, and managed apartments.
Super C‑class lock cylinder: Anti‑pick and anti‑drill construction raises the security level for projects with strict safety demands.
Door closer: Adjustable closing speed prevents slamming; when tuned correctly, it can assist in meeting accessibility guidelines.
Basic Parameters
Performance Item | Available Information | Buyer Notes |
|---|---|---|
Thermal Insulation | Polyamide thermal break, EPDM seals, polyurethane core lower heat transfer; U‑factor and SHGC depend on glass selection. | Request project‑specific U‑factor and SHGC data from DERCHI according to your climate zone and glazing. |
Wind Pressure Resistance | Engineering depends on frame size, anchorage, and site conditions; tested values available per configuration. | Confirm wind load ratings with the supplier for the intended building height and local codes. |
Water Tightness | Multi‑layer EPDM gaskets and sloped sill manage water drainage; test ratings available upon request. | Ask for water penetration test results if the door will face driving rain exposure. |
Air Tightness | Compression seals limit air leakage; performance is influenced by installation quality and frame tolerances. | Request air infiltration data for the chosen configuration to assess HVAC load impact. |
Sound Insulation | Insulated core and heavy panels reduce noise transfer; dB rating is not standard and varies with glass. | Request acoustic test reports if sound control is critical for the project. |
