Custom Top Hung Sliding Door

Narrow Profile for More Light

The WT-103 features a concealed linear track, no edge banding, a low-profile floor rail, and flush panel alignment. With a frame as narrow as 57 mm, this design reduces visual obstruction and increases the glass-to-frame ratio, letting more daylight into the room.

Verified Safety Standards

Each panel uses 2.0 mm wall-thickness aluminum, exceeding China's GB national standard. The door includes Opike-brand hardware, rollers rated for 80 kg, 8 mm tempered glass, and dual-direction soft-close buffers that protect against finger pinching during daily use.

Adaptable to Multiple Room Types

The WT-103 supports two-track, three-track linked, pocket door, and concealed door configurations. Single panels reach up to 1200 mm wide. Homeowners use it as custom sliding closet doors, bathroom dividers, or kitchen partitions — each layout is adjustable to the opening size.

Large-Scale Dimensions

Panel height extends to 2600 mm. Fixed glass sections cover up to 3.12 square meters. These dimensions allow wide openings without structural compromise, making this narrow sliding door suitable for floor-to-ceiling applications in both new builds and renovations.

U-Factor (U.S./1-P) – 0.39

The U-Factor measures how much heat transfers through the door. A lower number means less heat loss. The WT-103 top hung sliding door scores 0.39, indicating strong thermal insulation. This helps keep rooms warm in winter and cool in summer. It supports energy savings by reducing the need for constant heating or cooling.

Wind Pressure Resistance – 3K Pa

This value shows the maximum wind force the door can handle without deformation. The WT-103 Series sliding door resists wind pressure up to 3K Pa. The frame and top hung track system hold the door panel steady under high wind loads. This makes the door suitable for buildings in areas exposed to strong winds.

SHGC – 0.25

SHGC stands for Solar Heat Gain Coefficient. It measures how much solar heat passes through the glass. The WT-103 scores 0.25, meaning it blocks 75% of solar heat. This prevents rooms from overheating on sunny days and reduces cooling costs. Sliding glass door manufacturers use this metric to rate a door's ability to control solar energy intake.

Water Tightness – 300 Pa

This rating measures how well the door prevents water entry during rain. The WT-103 Series narrow sliding door withstands water pressure up to 300 Pa. The seal structure directs water away from the frame, reducing the risk of leaks. This keeps interior spaces dry during heavy rain and wind-driven storms.

Air Tightness – 4.5 m³/(m·h)

Air tightness indicates how much air passes through the closed door. The WT-103 limits air leakage to 4.5 m³/(m·h). Less air leakage means fewer drafts indoors. This helps maintain a stable indoor temperature and reduces the load on heating and cooling systems. The seal also helps block dust and outdoor pollutants from entering.

Sound Insulation – 30 dB

The door reduces outside noise by up to 30 dB. This level of reduction lowers traffic, construction, and street noise entering the room. The WT-103 Series narrow sliding door uses glass and frame construction that blocks sound transmission. This creates a quieter indoor space for homes, offices, and other environments where noise control matters.

Apartment

The WT-103 Series narrow sliding door saves floor space in apartments where room layouts are limited. The top hung design removes the need for bottom tracks, keeping floors clean and unobstructed. This door allows residents to divide living areas, bedrooms, or kitchens without losing square footage. It opens and closes with minimal effort, making it suitable for daily, high-frequency use in compact settings.

Home Office

The WT-103 Series top hung sliding door separates a home office from living areas without permanent walls. The narrow profile fits standard door frames and tight openings. It reduces noise transfer between rooms, supporting focused work during the day. When not in use, the door slides open to reconnect the office with the rest of the home. This solution supports flexible space use for remote workers.

Hotel

Hotels need doors that handle frequent use and maintain a clean appearance. The WT-103 Series sliding door runs on a top hung system, which reduces floor wear and lowers maintenance needs. It fits bathroom entries, closet openings, and room dividers. The narrow frame maximizes the visible glass area, letting natural light pass between spaces. Custom sliding closet doors using this system keep guest room interiors consistent.

Office Building

The WT-103 Series top hung sliding door provides a space-saving entry for office buildings. It works in meeting rooms, partitioned workspaces, and corridor access points. The top hung mechanism requires no floor rail, keeping walkways clear and safe. The door supports integration with building access systems. Its narrow frame allows a wide opening within a limited wall span, improving traffic flow in high-use areas.

Outdoor

For outdoor use, the WT-103 Series sliding door connects indoor spaces with patios, balconies, and garden areas. The top hung system keeps the bottom track-free, preventing water and debris buildup at the threshold. The door frame resists weather exposure and holds function across temperature changes. This design provides a clear transition between indoor and outdoor zones while maintaining a sealed barrier when closed.

Residential building

The WT-103 Series narrow sliding door addresses common space limits in residential buildings. It serves as an entry door, balcony access, or room divider. The top hung system runs without bottom tracks, reducing tripping risks for families with children or elderly members. This door fits standard wall openings and supports custom sizing from sliding glass door manufacturers. It delivers a long-lasting solution for daily residential use.

Exterior

The WT-103 Series top hung sliding door functions as an exterior door for building entrances, storefronts, and covered walkways. The frame handles wind load and weather exposure. The track-free bottom edge prevents dirt buildup and eases cleaning. This door allows wide openings for foot traffic or ventilation while maintaining security when locked. It suits both new construction and renovation projects that require a narrow sliding door at exterior positions.

Villa

Villas often feature wide openings and open-plan layouts. The WT-103 Series sliding door fits these spaces with custom panel sizes and configurations. The top hung mechanism supports large glass panels without a floor rail, preserving floor finishes. This door connects living rooms to gardens, pools, or terraces and provides unobstructed views with natural light.
