Sliding Door 3 panels on 2 tracks SFS WE 70

The WE 70 SFS 2-track 3-panel sliding door is a premium aluminum door system developed by TOSTEM, meeting requirements for stable operation, resistance to harsh environment, and modern design. Manufactured under international JIS standards, the product ensures safety, airtightness, and long-lasting durability, while maintaining a reasonable investment cost for various types of projects.

Frame construction and technical specifications

The door frame is designed with a depth of 72 mm, enhancing structural rigidity and overall system stability. The three-track version features a depth of 104 mm, offering better load-bearing capability during continuous operation. The bottom frame height of 35 mm improves water resistance while ensuring convenient passage. Glass thickness options range from 5 mm, 6 mm, to 8 mm, fulfilling diverse requirements for sound insulation, thermal insulation, and safety.

Waterproof and drainage system

The bottom frame features an integrated specialized drainage mechanism that swiftly directs and disposes of rainwater. This design prevents water infiltration into the interior, keeping the space dry and stable even under severe weather conditions.

Ergonomic handle and safety lock

The handle is ergonomically designed for a comfortable, firm grip during operation. A high-quality safety lock is also carefully fitted, providing anti-prying capabilities and enhancing the overall security of the door system.

Outer sash adjustable latch mechanism

The outer sash latch offers flexible adjustment, enabling users to easily align the clearance during use. This mechanism helps maintain long-term sealing, ensures operational stability, and extends the lifespan of the door system.

Direct integration with fixed glass sashes

The door structure allows for direct connection to fixed glass sashes without requiring additional horizontal mullions. This solution delivers a seamless surface, broadens the view, and optimizes natural daylighting for the interior space.

Sliding insect screen

The door system is equipped with an interior-mounted sliding insect screen, effectively blocking pests from entering. This mechanism promotes natural ventilation while maintaining a clean, open living environment.

Operational performance to international standards

According to JIS standards, the WE 70 SFS 2-track 3-panel sliding door achieves wind pressure resistance at S-1 (800 Pa), watertightness at W-2 (150 Pa), and airtightness at A-3. Sound insulation reaches 25 dB, creating a quiet environment suitable for both residential and office spaces. These parameters confirm the product’s stability, reliability, and sustainable operational efficiency.
