Engineered for high structural performance, hurricane resistance, and modern architectural aesthetics.
Grounded in 16 years of manufacturing rigor and backed by an international tier-1 supply network.
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.
Addressing the convergence of physical access security, IoT connectivity, and modern architectural envelope requirements.
The global construction market is experiencing a rapid transition from legacy key-and-tumbler mechanisms toward integrated biometric access control. As commercial developments and high-end residential towers prioritize contactless entry and dynamic authorization, our custom OEM aluminum fingerprint door solutions bridge the gap between architectural hardware and enterprise-grade electronic security.
Modern building codes across North America (IECC) and Europe (EPBD) strictly dictate thermal conductivity thresholds (U-factors). Grandex integrates multi-cavity polyamide thermal break systems within 6063-T6 extrusions, mitigating thermal bridging while accommodating heavy biometric lock mortises without compromising structural deflection standards.
For real estate developers and building product distributors, supplier stability is paramount. Utilizing over 1,200 verified raw material and hardware sub-vendors, Grandex ensures consistent batch alloy composition, micro-gap milling precision, and reliable lead times for high-volume international shipments.
Combining high-grade metallurgical profiles with semiconductor-level security hardware.
Our aluminum entrance door structures utilize 6063-T6 architectural grade aluminum extrusions engineered for high moment of inertia and flexural strength.
Execution across our 35,000 m² state-of-the-art production facility managed by 45 specialized QA personnel.
Verified by independent third-party laboratories to meet global structural and thermal regulations.
Our hurricane-rated aluminum smart door lines undergo rigorous Large Missile Impact Testing (TAS 201/202/203) for Florida HVHZ (High-Velocity Hurricane Zones). Certified NFRC thermal performance ensures compliance with ENERGY STAR® commercial baseline values.
Tested in accordance with Australian Standard AS2047 for air infiltration, water penetration resistance (up to 600Pa), and ultimate strength tests, making our systems compliant for coastal developments in Sydney, Melbourne, and Brisbane.
Full CE marking compliance covering mechanical durability, burglar resistance (RC2/RC3 rating according to EN 1627), and electromagnetic compatibility (EMC directive) for integrated biometric lock hardware.
Architectural deployment optimized for specific project environments.
Combining salt-mist resistant anodized aluminum profiles with high-security biometric entry. Eliminates structural degradation caused by ocean breezes while ensuring seamless, keyless access for villa owners.
Integrated panic bar panic hardware with biometric override and PTAC louver support. Tailored to meet high guest turnover demands, remote access management, and strict fire evacuation compliance.
Narrow-frame thermal break sliding and casement entrance setups that maximize natural light transmission while offering individual multi-tenant biometric security integration.
Driving next-generation innovation in biometric access hardware and sustainable aluminum systems.
Transitioning from 2D semiconductor fingerprint sensing to multi-modal AI edge computing modules, combining 3D facial recognition, palm vein analysis, and sub-dermal fingerprint mapping within a single low-power unit.
Native integration of the universal Matter over Thread standard across all OEM lock options, enabling out-of-the-box interoperability with Apple HomeKit, Google Home, Samsung SmartThings, and Amazon Alexa.
R&D development into micro-photovoltaic thermal break profile inserts that harvest ambient daylight, creating self-powered smart aluminum entrance doors that require zero manual battery replacements.
