High-performance certified window and door systems built for extreme weather durability, acoustic insulation, and thermal efficiency.
Pioneering precision engineering, architectural luxury, and scalable manufacturing capability for international commercial and high-end residential developments.
Established in 2014, Grandex Door Solutions Co., Ltd. is a premier entry door manufacturer operating from a modern 35,000 m² facility. With 16 years of industry expertise and 8 years of dedicated export experience, the company generates an annual export revenue of USD 28 million. Grounded in strong OEM and ODM trade backgrounds, our products primarily serve North America and Western Europe, supported by a network of over 1,200 supply chain partners. We cater to leading building material distributors, real estate developers, and commercial contractors. Quality is integral to our operations: supported by strict ISO 9001 certified internal testing and third-party laboratory verification, our 45-member QA team ensures rigorous quality control throughout production. Driven by an active R&D division with 85 specialized engineers, we introduced 120 new door designs last year and offer full custom solutions spanning custom dimensions, security locks, surface finishes, and decorative glass panels.
An architectural paradigm shift toward monumental openings, seamless design, and advanced thermal performance.
Modern commercial architecture and luxury residential estates increasingly demand oversized entry systems that transcend traditional hinged door limits. Custom OEM pivot entrance doors allow panel widths exceeding 2,500 mm and heights reaching up to 6,000 mm. By distributing mass along a vertical pivot axis rather than side hinges, structural loads are directly transferred into the foundation, facilitating smooth operation of panels weighing over 800 kg.
With stringent international energy codes (e.g., North American NFRC and European EnEV), thermal performance is paramount. Modern pivot systems utilize multi-chambered polyamide thermal break extrusions (PA66 GF25) paired with double or triple-glazed Low-E insulated glass units (IGUs). This structural configuration minimizes heat transfer, prevents interior condensation, and maintains U-factors under 0.24 BTU/h·ft²·°F.
Commercial developments in coastal environments—such as High-Velocity Hurricane Zones (HVHZ) in North America—require high dynamic wind-load and missile-impact resistance. OEM pivot doors undergo rigorous ASTM E1886/E1996 and TAS 201/202/203 testing, integrating SentryGlas® (SGP) structural interlayers and multi-point locking rods that withstand design pressures exceeding ±100 PSF.
