Primor Metal Door Co., Ltd. is a specialized OEM/ODM manufacturer transforming architectural blueprints into high-performance, export-ready door systems.
We do not lock projects into static catalog dimensions. Our engineering department reviews complete CAD/BIM window schedules, verifies wind load structural calculations, and issues shop drawings for sign-off prior to profile extrusion and CNC cutting.
Utilizing structural polyamide (PA66-GF25) thermal insulation bars inside 6063-T6 aluminum profile extrusions. Effectively eliminates thermal bridging, prevents interior frame condensation, and reduces overall building HVAC load.
Equipped with heavy-duty top and bottom motorized drop-bolts, side latching points, and anti-drill hardened steel plates. Seamlessly compatible with modern biometric 3D face scanners, keypad access, and smart home automation systems.
From solid cast aluminum decorative door faces to real wood-grain thermo-transferred finishes and AAMA 2605 compliant PVDF coatings, our surfaces withstand coastal salt spray, intense UV exposure, and severe temperature fluctuations.
Units are fully labeled by rough opening tag number, wrapped in protective foam film, and enclosed in heavy-duty fumigated plywood crates to ensure zero-defect arrival across international sea freight routes.
Supported by a physical presence across key international hubs including North American showrooms (Los Angeles, Bay Area, Houston, Dallas, Phoenix), offering local project teams physical profile samples and mock-ups.
Architectural exterior pivot doors have evolved from niche luxury millwork features into primary thermal and structural envelope components for high-end residential and commercial projects. As building codes worldwide tighten around thermal performance (such as NFRC standards in North America and EnEV in Europe), traditional pivot doors faced severe criticism regarding perimeter air infiltration and water penetration. Recent industrial R&D has reshaped pivot door technology to solve these critical engineering challenges.
Modern architectural trends demand larger openings—often exceeding 3,000mm in width and 4,000mm in height, with total leaf weights scaling up to 1,000 kg (2,200 lbs). The core technological advancement enabling this scale is the dual-way hydraulic concealed floor closer embedded directly into the bottom rail or floor slab:
Non-thermal aluminum pivot doors act as heat conductors, compromising indoor climate control and creating condensation damage on interior finishes. OEM manufacturing now incorporates multi-chamber aluminum profiles split by glass-fiber reinforced Polyamide (PA66-GF25) thermal insulation strips. When paired with triple-pane Low-E insulated glass units (IGU) filled with 90% Argon gas, total system U-factors drop below 0.19 Btu/h·ft²·°F (U-value ≤ 1.1 W/m²K), achieving full compliance with Energy Star and Passive House design parameters.
The mechanical key is rapidly being phased out of luxury entrance design. Modern OEM factory lines embed mechatronic multi-point locks directly within the aluminum profile stiles. These systems utilize motor-driven drop bolts triggered by encrypted biometric sensors, 3D facial recognition cameras, or building management systems (BMS) over IP/Zigbee protocols. Emergency battery backups and concealed manual mechanical bypass keys ensure uncompromised access during power outages.
The global procurement market for luxury fenestration systems is undergoing a structural shift. Developers, general contractors, and importing distributors are moving away from local intermediary catalog suppliers towards direct-with-factory OEM/ODM manufacturing partnerships. This transition is driven by three macro-economic procurement factors:
Architects no longer design around standard off-the-shelf door dimensions; instead, they expect the factory to conform to unique opening geometry. High-value construction projects demand bespoke frame depths, custom glass tinting, specific powder-coat RAL colors, and integrated sidelights. Direct OEM sourcing enables complete flexibility from early schematic CAD design to final manufacturing.
Procuring windows, sliding patio glass walls, garage doors, and massive front entry pivot doors from separate vendors often leads to finish discrepancies, misaligned sightlines, and finger-pointing when site installation issues arise. Global B2B buyers now prioritize manufacturers capable of fabricating the full exterior opening package under one roof—ensuring identical fluorocarbon anodizing batches, consistent thermal specifications, and unified factory warranties.
With coastal urbanization accelerating globally, wind-load resistance standards (such as ASTM E330, EN 12210, and Florida Building Code TAS 201/202/203 for High-Velocity Hurricane Zones) are mandatory. B2B buyers require factories that provide verified structural test reports, FEA (Finite Element Analysis) calculations, and hurricane-impact laminated glass options to satisfy local building officials.

Technical and commercial answers for architects, general contractors, developers, and global importers.
Our OEM pivot doors utilize a dual-seal perimeter system. The vertical stiles feature continuous EPDM rubber gaskets combined with magnetic compression strips. For the critical top and bottom horizontal rails, we integrate automatic mechanical drop-down seals that automatically extend upon door closure, forming an airtight barrier against floor thresholds without dragging during swing operation.
To provide a technical proposal and quotation, please supply your architectural elevation drawings, window/door schedules, or rough opening dimensions (Width x Height x Wall Depth). CAD (.dwg/.dxf) or PDF files indicating opening directions, glass specifications, and smart lock preferences allow our engineering team to generate precise shop drawings within 24–48 hours.
Our heavy-duty floor-concealed hydraulic pivot systems support maximum single door panel dimensions up to 2,000mm in width and 4,500mm in height, with a maximum load capacity of 1,000 kg (2,200 lbs). All heavy-capacity units undergo factory cycle testing exceeding 100,000 open-close operations under maximum load conditions.
Yes. We factory-install motorized mechatronic lock bodies (such as Dormakaba, GU, or customized OEM smart locks) that seamlessly connect with dry-contact relay inputs, RS485, Zigbee, Z-Wave, or KNX smart home protocols. Biometric scanners, keypads, and video intercoms can be flush-mounted directly into the aluminum door stile or pull handle.
For coastal environments within 5 km of seawater, we specify marine-grade pre-treatment anodizing (25+ microns) or AAMA 2605 compliant PVDF fluorocarbon coatings. These surface treatments withstand 3,000+ hours of continuous salt spray testing without blistering, chalking, or color fading.
Every unit is fully assembled and tested at the factory before being disassembled into marked components or packed as pre-hung frames. Components are wrapped in anti-scratch foam film, edge-protected with heavy cardboard, and enclosed within fully sealed, fumigated ISPM-15 compliant plywood crates suitable for crane handling and containerized sea transport.
