Explore our flagship engineered doors tested for extreme wind loads, thermal insulation, and architectural elegance.
A global leader in engineering, manufacturing, and exporting insulated entry door systems for high-end residential and commercial developments.
Established in 2017, Foshan Primeval Doors Industry Co., Ltd. operates from a modern manufacturing facility of 12,000 m². Backed by 11 years of industry engineering experience and 5 years of international export trade, the company generates an annual export revenue of USD 8,500,000.
Quality control is strictly enforced through systematic IQC-IPQC-FQC inspection procedures along with rigorous thermal conductivity and salt-spray corrosion testing. A skilled QC team of 22 inspectors oversees every step of the production process. Supported by 420 trusted supply chain partners, our trade background covers direct OEM export and private-label customization, serving primary markets in Australia, New Zealand, and North America.
Our client base consists mainly of residential building supply importers, architectural designers, and regional wholesalers. Driven by continuous innovation, our R&D group of 38 engineers introduced 75 new entry door products last year. Customization options include custom frame depths, double-glazed decorative glass inserts, powder-coated color palettes, and heavy-duty weatherproofing seals.
Understanding the science behind high-efficiency structural insulation, U-Factor reduction, and acoustic decay in modern architectural entry systems.
We utilize Polyamide 66 reinforced with 25% glass fiber (PA66-GF25) structural insulation strips. This creates an impermeable thermal break inside the aluminum extrusion, effectively stopping thermal bridging, reducing frame heat transfer by up to 65%, and preventing interior condensation.
Our Insulated Glass Units (IGUs) incorporate double or triple-pane tempered safety glass filled with 90% Argon gas. Soft-coat Low-E (Low Emissivity) multi-layer silver coatings reflect infrared light, dramatically lowering SHGC (Solar Heat Gain Coefficient) while preserving high visual light transmittance.
Using multi-chamber profiles combined with structural silicone glazing (SSG) and continuous EPDM automotive-grade weatherstripping, our insulated entry doors achieve Sound Transmission Class (STC) ratings up to 42 dB and withstand extreme wind loads up to ±5000 Pa.
| Performance Standard | Technical Metric / Specification | International Standard Compliance |
|---|---|---|
| Thermal Transmittance (U-Value) | U-Factor ≤ 1.2 to 1.8 W/m²·K (0.21 - 0.31 BTU/h·ft²·°F) | NFRC 100/200, Energy Star V7.0 |
| Solar Heat Gain Coefficient (SHGC) | Customizable from 0.18 to 0.35 depending on Low-E stack | AS2047, NFRC certified |
| Structural Wind Load Performance | Design Pressure (DP) up to ±70 PSF (3350 Pa to 5000 Pa) | Florida NOA / Miami-Dade HVHZ |
| Acoustic Insulation Rating | STC 38 - 45 dB / OITC 32 - 38 dB | ISO 10140-2 / ASTM E90 |
| Air Infiltration & Water Resistance | Air Leakage < 0.1 cfm/ft²; Water Resistance 750 Pa | AS4420.2 / ASTM E331 |
Every insulated entry door undergoes 10 meticulous manufacturing stages overseen by 22 dedicated IQC, IPQC, and FQC inspectors.
Our 12,000 m² workshop is fully outfitted with heavy-duty CNC machinery ensuring millimeter-level tolerances across all custom profiles.
Our 38 R&D engineers convert architectural concepts into millimeter-precise CAD schematics and structural FEA calculations.
Why Tier-1 global contractors and building material distributors partner with Foshan Primeval Doors Industry Co., Ltd.
Situated in Foshan—the world's capital of aluminum extrusion and architectural hardware—we leverage direct access to 6063-T5/T6 primary aluminum billets, powder coating giants (AkzoNobel, Tiger), and elite hardware ecosystems, reducing unit costs by 25-35% without quality trade-offs.
We engineer entry solutions configured to pass localized building codes seamlessly: NFRC Energy Star rating for USA/Canada, Florida NOA for high-velocity hurricane zones (HVHZ), AS2047 & AS1288 certification for Australia/New Zealand, and CE markings for European Union directives.
To eliminate international shipping damage, all units receive 5-layer protective packing: protective film, foam corner protectors, vacuum-sealed plastic wrapping, and fully enclosed IPPC-stamped fumigated plywood crates optimized for container utilization.
Clear engineering and commercial answers designed for architects, wholesalers, and project managers.
Standard aluminum extrusions conduct heat rapidly, making them inefficient in hot or freezing climates. Thermal break entry doors utilize a low-thermal-conductivity polyamide barrier (PA66-GF25) inserted between the interior and exterior aluminum profiles. This structural break drastically stops thermal transfer, prevents interior condensation, and cuts HVAC energy bills by up to 30%.
Our profiles undergo rigorous physical testing for deflection, water penetration, and air infiltration under NFRC and AS4420 standards. For Florida NOA and hurricane zones, we integrate heavy-wall 6063-T6 aluminum alloys, PVB/SGP laminated impact glass inserts, and German multi-point locking hardware to withstand design pressures exceeding ±70 PSF.
We offer total flexibility including custom frame depths (60mm to 150mm), customized glass insert patterns (frosted, Low-E, tinted, smart electrochromic glass), surface finishes (powder coating, fluorocarbon PVDF, anodizing, wood grain transfer), and hardware configurations (German Siegenia, Hoppe, Roto, or high-security smart biometric locks).
Standard OEM production lead time is 25 to 35 days from technical drawing confirmation. Our flexible manufacturing setup accommodates low MOQ orders for custom villa projects (down to 10 sets) as well as full-container volume orders (20GP / 40HQ) for commercial developers.
