Precision-fabricated thermal break profiles, structural double-tempered insulated glazing, and multi-point security hardware manufactured under strict ISO 9001 and CE compliance protocols.
In modern fenestration engineering, CE marking is not merely a export formality—it is a rigorous baseline certifying structural integrity, thermal transmittance, watertightness, and wind-load performance for international building safety.
Engineered with continuous EPDM triple-gasket seals and precision miter joints. Our exterior door systems achieve Class 4 performance (600 Pa test pressure), ensuring minimal uncontrolled air leakage and enhanced heating/cooling efficiency.
Featuring hidden multi-stage drainage channels and pressure-equalized sub-frames. Tested under extreme artificial rain up to Class E1050 (1050 Pa), preventing moisture ingress even in severe coastal hurricane conditions.
Constructed from high-tensile 6063-T6 aluminum alloys with reinforced structural mullions. Certified up to Class C5 / B5 (structural deflection limits exceeding L/300 under high static wind pressure).

As global building standards shift toward net-zero operational carbon, severe weather resiliency, and industrial prefabrication, architectural aluminum door procurement is undergoing a structural evolution.
International developers increasingly demand Environmental Product Declarations (EPDs). Future procurement prioritizes aluminum billets smelted using renewable hydro-power and high-recycled-content extrusions, reducing upstream embodied carbon by up to 65%.
Architectural aesthetics lean heavily toward minimal interlock profiles (16mm to 21mm visual width). Structural silicone bonding allows large glass panes to act as load-bearing components, pushing single-panel dimensions above 12 square meters without structural compromise.
Commercial and luxury residential buyers require seamless access control. Modern exterior doors integrate motorized concealed drives, facial recognition biometrics, and multi-point smart solenoids compatible with KNX and Crestron building management protocols.
To reduce expensive on-site labor and assembly errors, overseas procurement is transitioning from knock-down (KD) kits to pre-assembled, unitized frame-and-door modules fitted with factory-glazed units, pre-tested hardware, and expansion joint sub-frames.
Accelerated weathering standards mandate PVDF (Fluorocarbon 3-coat system) coatings and hard-anodized marine-grade surface treatments (>25 microns) capable of surviving 1,000+ hours of salt spray exposure (ASTM B117) for coastal developments.
Leading architectural firms require Revit and IFC BIM files before issuing tender documents. Direct-from-factory suppliers offering digital parametric door objects streamline project approvals and eliminate dimensional clashes prior to manufacturing.
Founded in 2004 in Foshan—China’s global center for aluminum processing—Doorreme operates a modern 123,000 m² production base equipped with automated German Elumatec CNC machining centers and Italian powder coating lines.
With over 800 skilled employees and a dedicated R&D engineering staff, we produce up to 500,000 m² of architectural windows, doors, and curtain wall systems annually, serving commercial contractors, developers, and distributors across 140+ countries.
Direct answers to the most common questions raised by architects, general contractors, real estate developers, and international importers.
We supply certified Factory Production Control (FPC) documentation and official Type Testing Reports (ITT) issued by accredited European Notified Bodies. Each export shipment includes a formal Declaration of Performance (DoP) matching your project specifications.
Our standard structural wall thickness ranges from 1.6mm up to 3.0mm using primary 6063-T6 architectural grade aluminum extrusions, complying with EN 755 and EN 12020 standards for structural rigidity under heavy wind loads.
Yes. 100% of our production is engineered to order. We customize door dimensions, frame elevations, surface treatments (RAL powder coating, AkzoNobel PVDF, wood grain sublimations, or anodizing), and custom grid designs according to your architectural CAD drawings.
We utilize high-grade Technoform PA66 GF25 (25% glass fiber reinforced polyamide) thermal break strips inserted between outer and inner aluminum profiles. Combined with Low-E insulated glass units filled with Argon gas, we achieve U-values down to 0.8 - 1.4 W/m²K.
All door glass units feature fully tempered safety glass complying with EN 12150 and ANSI Z97.1. We offer double glazing (e.g., 5mm+18A+5mm), triple glazing, PVB/SGP laminated security glass for hurricane-prone regions, and acoustic PVB layers for sound reduction up to 45 dB.
Standard production cycles are 25 to 35 business days following final approval of technical CAD production drawings and color sample sign-offs. Accelerated production lines are available for urgent commercial construction schedules.
Doors are packaged using a 5-layer protective system: foam wrapping, protective corner guards, waterproof shrink film, individual corrugated cartons, and non-fumigation solid plywood steel-banded crates with forklift bases.
Yes. We supply comprehensive installation manuals, 3D exploded view assembly diagrams, and video tutorials. For major commercial curtain wall and complex door projects, our technical engineers can provide remote online guidance or site dispatch service.
