Engineered for mission-critical commercial hubs, institutional facilities, and modern building automation networks requiring thermal integrity, impact resistance, and continuous access control.
Grandex Door Solutions operates an integrated engineering campus calibrated to provide international enterprise partners with uninterrupted production volume, tight tolerance controls, and traceable quality governance.
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.
Commercial building operators and Tier-1 general contractors require data-proven reliability, energy mitigation, and universal accessibility across modern access points.
Global commercial facilities prioritize zero-contact portals. Modern automatic doors mitigate pathogen transmission vectors in high-density hospitals, transport hubs, and corporate campuses via dual-tech Doppler and active infrared sensor arrays.
Driven by strict ASHRAE 90.1, Title 24, and EN ISO 10077 standards, procurement models demand integrated thermal-break aluminum extrusions paired with argon-filled low-E glass to systematically lower HVAC cycling loads.
Architects require kinetic entryways that speak standard protocols—BACnet, Modbus, and LonWorks. Real-time cycle metrics, drive motor amp-draw variations, and sensor recalibrations streamline preventative maintenance before seal breakdown.
Tailored architectural entrance systems engineered for varying operational stresses, envelope constraints, and life-safety imperatives.
Integrated emergency breakout systems engineered to withstand continuous duty cycles (>2,000,000 actuations). High-torque brushless DC motors provide quiet operation and anti-pinch safety curtains prevent pedestrian entrapment.
Airtight perimeter sealing coupled with non-turbulent air migration layouts. Features interlock algorithms, touchless wave-to-open sensors, and anti-static architectural finishes resistant to heavy hospital disinfectants.
Heavy-duty thermal-break frames matched with reinforced drive belts and high-yield structural anchoring. Engineered to counter negative wind-load vortexes while keeping air curtain systems synchronized during high-traffic shifts.
Take an inside look at our 35,000 m² production ecosystem. Full CNC automation, multi-axis profile machining, and rigorous physical property diagnostics underpin every door leaving our factory floor.
From passive infrared detection to AI-powered computer vision arrays, Grandex leads the trajectory of commercial automatic doors into intelligent spatial interfaces.
Replacing traditional radar cones with neural-network-driven optical sensors. The door calculates foot-traffic trajectories, opening strictly when cross-path pedestrians intend entry—preventing unnecessary climate control escape.
Micro-LiDAR modules integrated into header profiles map volumetric clearance in 3D, creating zero-deadzone virtual curtains that identify wheelchairs, carts, and crawling infants without mechanical pressure pads.
Next-gen operator gearing coupled with micro-regenerative motor controllers recapture rotational inertia during deceleration phases, converting dynamic movement into auxiliary power for internal transceivers.
Integrated microprocessors continuously cross-check load resistances across nylon rollers and drive belts, scheduling OTA updates and pushing maintenance tickets before wear induces field failures.
Our engineering outputs conform to strict safety directives, building codes, and structural integrity mandates across the world’s most stringently regulated markets.
Engineered to comply with ANSI/BHMA A156.10 (Standard for Power Operated Pedestrian Doors), ADA clearance requirements, UL 325 safety protocols, and Florida Building Code (FBC) impact certifications for hurricane-prone corridors.
Full conformance to EN 16005 (Power Operated Pedestrian Doorsets - Safety in Use) and the Machinery Directive 2006/42/EC. Featuring dual fail-safe redundant safety circuits, emergency breakout monitoring, and acoustic attenuation ratings.
Precision-tested to satisfy AS 5007 (Powered Doors for Pedestrian Access and Egress) along with full NATA-accredited AS 2047 fenestration structural standards for structural deflection, water resistance, and air infiltration metrics.
Explore our complete manufacturing spectrum—spanning soundproof accordion systems, thermally decoupled storefronts, and hurricane-certified structural fenestration.
In-depth responses covering engineering specifications, sensor integration parameters, and custom factory tolerances.
Our automated systems feature redundant safety mechanisms compliant with EN 16005 and ANSI A156.10 standards. These include combined microwave motion detection and dual-curtain active infrared presence sensors. In the event of a power outage or fire alarm activation, our mechanical counterbalance or spring-loaded breakout systems provide emergency panic opening instantly.
Yes. Utilizing polyamide (PA66) thermal breaks, multi-cavity aerospace-grade 6063-T5 or 6063-T6 aluminum alloys, and triple-pane Insulated Glazing Units (IGUs) filled with argon gas and Low-E coatings, we consistently hit NFRC-certified U-factors down to 0.20, drastically minimizing solar gain and building conduction losses.
Across our 35,000 m² production facility, Grandex deploys double-head precision cutting saws and CNC machining centers holding linear tolerances within ±0.2 mm and angular tolerances within ±0.1°. This precision prevents door sash binding, extends roller system operational life, and ensures hermetic perimeter seal contact.
Every commercial operator control board we build features modular dry-contact and RS485 communication interfaces. We readily accommodate direct BMS tie-ins for remote lock schedules, biometric access modules, fire safety override loops, and cycle count logging for facility management teams.
