Product Overview & Technical Data
Product Overview
Three-seal frame system for European climate zones. 6063-T5 aluminium extrusion, 30 mm PA66-GF25 thermal-break strip, K-value from 1.5 W/(m²·K), acoustic reduction ≥ 35 dB. Delivered as full 75 Series profile suite (frame · sash · beading · mullion · adapter).
When designing wide-opening balconies, patios, and luxury architectural facades, choosing the right sliding door aluminium profile is crucial for structural stability and smooth operation. The JP108 heavy-duty system delivers exceptional performance, combining robust engineering with modern aesthetics.
Key Technical Features of JP108 System
Engineered for demanding residential and commercial applications, the sliding door aluminium profile utilizes high-grade 6063-T5 aluminum extrusion. It features a 108 mm frame depth designed to support oversized glass panels while maintaining superior weather resistance.
Key technical specifications include:
Profile system: JP108 heavy-duty sliding door series with a 108 mm frame.
Material grade: Premium 6063-T5 aluminium extrusion.
Weather sealing: Dual weather-stripping for optimal air and water tightness.
Load capacity: Tandem stainless-steel rollers rated for 400 kg leaf weight per panel.
Application: Wide-opening balconies, patios, and full-height grand entrances.
Advantages of Heavy-Duty Aluminium Profiles
Investing in a high-performance sliding door aluminium profile ensures long-term durability and smooth daily operation. The reinforced mullions and heavy-duty tracks prevent sagging and resist high wind loads, making it an ideal choice for coastal or high-rise buildings.
Triple-Seal Weather Barrier
Outer weather seal + equal-pressure chamber + inner airtight seal. Rain, dust and condensation are managed independently.
Multi-Cavity Extrusion
Frame and sash both use a 3+ chamber cross-section — the trapped air acts as an additional insulation layer.
Isothermal Extrusion Control
Closed-loop temperature control during extrusion holds billet temperature within ±5°C, giving consistent grain size and surface.
Long-Rod Hot-Shear
Aluminium billets are hot-sheared instead of sawn, cutting material loss and eliminating cross-section deformation.
Chromium-Free Pre-Treatment
RoHS-compliant pre-treatment line, no hexavalent chromium — safer for factory workers and downstream fabricators.
20.8 mm Universal Beading
Same beading profile fits frame, in-swing sash, out-swing sash, mullion and adapter — cuts SKU count and fabrication error.
