Entrance Sliding Door 4 panels on 2 tracks WE 70

TOSTEM’s WE 70 entrance sliding door 4 panels 2 tracks is developed using Japanese standard manufacturing technology. The door system ensures stable mechanical performance, high structural durability, and smooth operation under various usage conditions.

Frame System and Waterproofing

The door frame is fabricated from extruded aluminum alloy with an anodized or powder-coated surface finish, ensuring color durability and corrosion resistance. The bottom frame profile features an integrated grooved drainage module that directs and evacuates rainwater outward, maintaining airtightness and effectively preventing water backflow into interior spaces.

Handle Mechanism and Multi-Point Lock

The door handle is ergonomically designed to create balanced opening and closing force while reducing operational friction. The safety locking system utilizes a multi-point mechanism, enhancing resistance to prying and ensuring security for the building.

Latch Mechanism and Adjustability

The outer sash is equipped with a flexible adjustable latch, allowing fine-tuning of the clearance and sealing pressure between the sash and frame during installation. Consequently, the door system achieves high stability, maintains airtightness, and minimizes misalignment over long-term use.

Integration with Fixed Partitions

The WE 70 entrance sliding door 4 panels 2 tracks allows direct coupling with fixed glass partitions without the need for horizontal transom bars. This solution optimizes design continuity while expanding line-of-sight and increasing natural daylight penetration.

Sliding Insect Screen System

The door system is equipped with a co-axial sliding insect screen installed inside the frame. This structure prevents pest intrusion while allowing air circulation and maintaining an unobstructed field of view.

Technical Specifications and Performance Standards

The door frame has a depth of 72 mm; for the 3-track sliding configuration, the frame depth reaches 104 mm. The bottom frame height is 35 mm, supporting glass thicknesses of 5 mm, 6 mm, and 8 mm. The system complies with JIS testing standards with performance metrics including: wind pressure resistance S-1 (800 Pa), water tightness W-2 (150 Pa), air tightness A-3, and sound insulation up to 25 dB. These values affirm the product’s mechanical stability, weather resistance, and acoustic efficiency, meeting the technical requirements of diverse residential and commercial projects.
