Crafted from thickened 2.5 mm aviation-grade 6063-T5 aluminum alloy extrusion (0.87 kg\/m), this specialized sliding rail features an inward-curved concave running groove tailored for concave-profile hanging rollers and buffer pulleys. Ideal for pocket doors, heavy sliding kitchen dividers, bathroom partitions, and commercial interior doors, it prevents derailment, absorbs carriage vibration, and delivers long-term durability without sagging or deformation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003ePrecision Concave Guide Geometry:\u003c\/strong\u003e Engineered with an inward-curved concave raceway that self-centers the hanging roller carriage, preventing lateral play, wheel slippage, and rail derailment.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eThickened 2.5 mm Aluminum Alloy Extrusion:\u003c\/strong\u003e Heavy wall thickness and structural reinforcement ribs provide a solid 0.87 kg per meter profile, supporting heavy architectural solid wood and framed glass doors up to 120 kg (265 lbs).\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eSilent High-Speed Rail Technology:\u003c\/strong\u003e Optimized contact contour minimizes rolling friction and resonance, delivering smooth, whisper-quiet door operation inspired by high-speed rail transit tracks.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eIntegrated Soft-Close Buffer Mounting Slot:\u003c\/strong\u003e Features dedicated internal channels for seamless installation of two-way hydraulic soft-close dampers and mechanical limit stops.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eCorrosion-Resistant Anodized Finish:\u003c\/strong\u003e Premium matte anodized black finish resists moisture, bathroom humidity, scratching, and oxidation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Heavy-Duty Overhead Sliding Door Track with Concave Guide Rail\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Extruded 6063-T5 Aluminum Alloy\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eWall Thickness:\u003c\/strong\u003e 2.5 mm (Thickened profile)\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eLinear Weight:\u003c\/strong\u003e 0.87 kg \/ meter (0.58 lbs \/ ft)\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eAvailable Finishes:\u003c\/strong\u003e Anodized Matte Black \/ Architectural Silver\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eStandard Length:\u003c\/strong\u003e 1.0 meter (Custom lengths up to 3.0m available for project orders)\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eCompatible Hardware:\u003c\/strong\u003e Concave-wheel hanging rollers, 4-wheel\/8-wheel buffer carriages, and two-way soft-close dampers\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eDoor Weight Rating:\u003c\/strong\u003e Up to 120 kg (265 lbs) per door leaf (paired with heavy-duty roller kits)\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eApplications:\u003c\/strong\u003e Kitchen sliding doors, bathroom glass doors, interior room dividers, pocket doors, and hospitality suites\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWholesale \u0026amp; OEM Capabilities\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eFactory-Direct Supply:\u003c\/strong\u003e Ningbo Dimon manufactures architectural sliding track systems for door fabricators, commercial interior contractors, and hardware distributors.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eCustom Fabrication:\u003c\/strong\u003e Precision cut-to-length services, custom pre-punched mounting hole patterns, and custom powder-coated or anodized architectural finishes.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eExport Packaging:\u003c\/strong\u003e Individual protective film sleeves with heavy-duty rigid paper corner guards, packed in export wooden crates or reinforced master cartons.\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Ningbo Dimon Metal Products Co.,Ltd","offers":[{"title":"1 meter","offer_id":47111216070795,"sku":null,"price":85.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0575\/0295\/7707\/files\/ca44465ba740e92764a5e562a31ad611.jpg?v=1793864960","url":"https:\/\/nbdimon.myshopify.com\/zh\/products\/concave-buffer-sliding-door-track","provider":"Ningbo Dimon Metal Products Co.,Ltd","version":"1.0","type":"link"}
