As a committed aluminum sliding door supplier Osaka buyers have come to rely on, DERCHI delivers custom aluminum sliding door systems engineered in our Foshan manufacturing base. We serve importers, contractors, and developers across the Kansai region with scalable solutions for residential and commercial projects.
70,000㎡ Foshan factory with 600+ employees ensures consistent bulk supply for aluminum sliding door supplier Osaka orders.
Series like Q9 slim frame, Q5 residential, and 135D waterproof cover diversified project needs, from luxury villas to commercial buildings.
Full OEM/ODM services allow custom profiles, glass, colors, and hardware engraving to match your brand requirements.
As an aluminum sliding door supplier Osaka projects depend on, DERCHI equips each system with 6063-T5 aluminum frames, double or triple glazing, EPDM seals, and silent roller mechanisms. The hidden drainage track efficiently handles Osaka’s frequent rain, while multi-point locks and anti-sway wheels add stability.
When specifying sliding glass doors Osaka architects prefer, performance differentiation is essential. DERCHI’s Q9 series offers 2.2mm profile thickness and wind resistance up to 5 kPa for coastal or high‑rise sites, while the Q5 series delivers reliable 30dB sound insulation at a lower cost. The 135D’s double‑pane waterproof design makes it suitable for exterior and interior openings in renovation projects. As an aluminum door manufacturer Osaka partners trust, we tailor each order—from glass type and track layout to hardware pairing—to meet Japanese building demands.

Application Scenarios
Apartment: Q5 sliding doors fit small Osaka balconies without swing clearance. They reduce street noise by 30dB, and slim frames preserve interior daylight.
Home Office: A frosted‑glass aluminum door separates workspace from living areas quietly; its sleek look matches modern renovation projects.
Hotel: Q9 slim frames provide wide garden views and 5kPa wind resistance for upper‑floor rooms. Silent rollers ensure undisturbed guest sleep.
Office Building: Heavy‑duty sliding doors with 4.5kPa wind rating handle high traffic. Multiple tracks allow seamless lobby access and egress.
Outdoor: For rooftop or garden installations, buyers should confirm water tightness ratings and corrosion‑resistant coatings suit Osaka’s rainy summers. Barrier‑free sills may be required.
Residential Building: Q5 series offers cost‑effective thermal performance (~2.5 W/m²K) and durable operation for multi‑unit developments, with custom colors to match façades.
Exterior: Exposed sliding doors must withstand wind and rain. We recommend 135D with 350Pa water tightness; however, project‑specific weather testing is essential before finalizing.
Villa: Q9 doors open onto gardens with glass panels up to 18㎡. High wind load resistance (5kPa) keeps interiors safe during typhoons while framing scenic views.
