Product Description

Large-span lifting and sliding doors are ultra-large door systems that open and close horizontally by lifting the door leaf vertically off the track. A single leaf can reach widths exceeding 6 meters and heights exceeding 4 meters. They are designed for applications requiring barrier-free access, high daylighting, or flexible space partitioning. Their core features include a large span, low friction, and excellent sealing. Combining mechanical lifting with intelligent control technology, they deliver a "light push, snap-together" experience. They are widely used in high-end residences, commercial spaces, industrial plants, and public buildings.

1. Aluminum Doors Structure Type

Monorail Lifting and Sliding Structure

Design Principle: A lifting mechanism is installed at the bottom of the door leaf. A motor or manual crank lifts the door leaf vertically 10-15 mm, releasing it from the track and sliding it horizontally.

Advantages: Low track flatness requirements make them suitable for applications with slightly sloping floors (such as courtyard entrances). A single leaf can support up to 800 kg and has a span exceeding 6 meters.

Dual-Track Synchronous Lifting Structure

Mechanical Innovation: Two doors lift and slide synchronously, utilizing a sprocket drive system to ensure consistent movement with an error of ≤1mm.

Application Scenarios: Meeting rooms, exhibition halls, and other spaces requiring full opening, with an opening area of over 80%, creating a "column-free" effect.

Folding, Lifting, and Sliding Structure

Folding Logic: Aluminum Folding Doors consist of 3-5 hinged modules that fold and stack on one side after lifting, saving space.

Data Support: When folded, the door occupies a width of only 0.3 meters (compared to 1.2 meters for traditional sliding doors), making it suitable for narrow areas such as balconies and terraces.

Intelligent Electric Lifting Structure

Drive System: Integrates a servo motor (0.75-2.2kW) and a planetary reducer, supporting variable frequency speed regulation (0.1-0.5m/s) and soft start/stop.

Intelligent Control: Automatic opening and closing can be achieved via a mobile app, voice assistant, or sensors (such as wind and rain sensors and infrared motion sensors), with support for scheduled scheduling and remote monitoring.

2. Material Features

High-Strength Aluminum Alloy Frame

Alloy Options: 6063-T5 or 6061-T6 aluminum alloys are used. The former boasts a tensile strength of ≥160 MPa and an elongation of ≥8%, making it suitable for complex cross-section extrusion. The latter, with a strength of 310 MPa, is suitable for load-bearing structural components.

Surface Treatment:

Fluorocarbon spray coating: Thickness ≥40 μm, acid rain corrosion resistance (no rust after 2000 hours of salt spray testing), color retention ≥90%, suitable for coastal areas or heavily polluted areas.

Wood Grain Transfer: Thermal transfer technology simulates natural wood grain (such as oak and walnut) for a realistic feel, meeting the needs of high-end interior designs.

Tempered Glass and Composite Panels

Glass Configuration:

Double-layer insulated tempered glass (6mm + 12A + 6mm): Double Glass Entry Aluminum Commercial Doors offer a sound insulation performance of 32 dB (RW) and a thermal insulation coefficient (U-value) ≤2.8 W/(m²·K). Laminated safety glass (8mm + 1.52mm PVB + 8mm): 5 times the impact resistance of ordinary glass, remains intact even if shattered, and complies with EN 12600 1B1 safety standards.

Composite panels: Optional aluminum honeycomb panels (density 0.8g/cm³), rock wool panels (fireproof Class A), or PC endurance panels (light transmittance ≥88%) are available to meet insulation, fire protection, or lighting requirements.

High-performance sealing and hardware system

Sealing strips: Utilize an EPDM and silicone composite structure, temperature resistant from -50°C to +150°C, with a compression rebound rate ≥70%, ensuring airtightness (airtightness grade 4) and watertightness (watertightness grade 3).

Pulley assembly:

Load-bearing pulleys: Utilize high-chrome steel bearings with PA66 and GF30 wheel bodies. Each pulley has a load capacity of ≥500kg and a lifespan exceeding 100,000 push and pull cycles. Guide wheels: Equipped with self-lubricating graphite bushings, with a friction coefficient of ≤0.1, reducing push and pull resistance by over 50%.

3. Advantages

Extremely wide access and light-dense capabilities

With a single door width exceeding 6 meters and a height of 4.5 meters, it can accommodate forklifts and large equipment. With over 80% glass coverage, daytime daylighting reduces lighting energy consumption by over 30%.

Case Study: A car showroom implemented a 12-meter-wide electric lift-and-slide door, increasing daily visitor traffic by 40% and significantly enhancing the display quality of its exhibits.

Low-friction and long-life design

The lift mechanism reduces friction between the door leaf and the track, extending the pulley life to over 150,000 cycles (compared to 50,000 cycles for conventional sliding doors). The aluminum alloy frame meets AAMA 2603 corrosion resistance standards and requires no replacement for 20 years.

Highly Sealed and Energy-Efficient

The multi-stage sealing design (brush + gasket + airbag) combined with insulating glass achieves a K value of ≤2.0W/(m²·K) for the entire door, saving 50% less energy than ordinary doors. Airtightness reaches GB/T 7106-2008 Level 8, effectively blocking PM2.5 and noise.

Quick Installation and Modular Expansion

The use of pre-assembled frames and standardized components reduces on-site installation time by 60%. Later additions of motorized systems, fingerprint locks, or sunshades are supported, reducing initial investment costs.

4. Aluminum Lift And Slide Doors: Suitable for high-end residences and villas.

The courtyard entrance door features a powered folding and lifting structure, equipped with an intelligent security system (facial recognition + remote alarm), providing dual functions of "one-touch opening and closing + security protection."

Interior partitions: A wood-grain transfer aluminum frame and laminated glass divide the living and dining areas while maintaining visual transparency.

Commercial and Public Buildings

Main entrances of shopping malls: 10-meter-wide, double-track lifting doors allow for rapid passage during peak hours and close at night to create an enclosed space, enhancing security.

Stadiums and exhibition centers: Folding lifting doors allow for quick separation of activity areas, adapting to events or exhibitions of varying sizes.

Industrial and Logistics Facilities

Loading and unloading doors of factories: Utilizing a steel frame and rock wool composite panels, they offer a fire resistance rating of ≥1.5 hours, meeting fire safety regulations. The electric lifting system supports high-frequency opening and closing (over 200 times per day).

Cold storage doors: Integrated low-temperature sealing strips (non-hardening at -40°C) and electrically heated rails prevent frost formation and reduce cooling loss by 30%.

Special Environmental Applications

Flood control gates: A lifting structure with waterproofing strips allows for rapid closure during flood warnings, with a water pressure resistance of up to 0.5 MPa (equivalent to a water depth of 5 meters).

Soundproof room doors: Utilizing double-layer steel panels and sound-absorbing foam (NRC ≥ 0.9), they offer a sound insulation rating of 45 dB, making them suitable for recording studios or equipment testing rooms.

5. Industry Trends

Balancing Lightweight and High Strength: Developing carbon fiber-reinforced aluminum alloys (50% stronger, 30% lighter), pushing the performance limits of traditional materials.

Intelligent Upgrades: Integrating AI cameras (behavior analysis), environmental sensors (temperature, humidity, and PM2.5), and 5G communication modules enables remote monitoring and predictive maintenance.

Sustainable Design: Utilizing recycled aluminum alloys (≥75%) and a removable structure, the doors support full lifecycle recycling and meet LEED v4.1 certification requirements.

Large-span lifting and sliding doors, with their core advantages of "extra-large size, intelligent convenience, energy efficiency, and safety," are becoming a benchmark solution for modern building entrances and space dividers, driving the industry's transformation toward "boundaryless design" and "green intelligence."
