Product Overview & Technical Data
Product Overview
Three-seal frame system for European climate zones. 6063-T5 aluminium extrusion, 20 mm PA66-GF25 thermal-break strip, K-value from 1.6 W/(m²·K), acoustic reduction ≥ 32 dB. Delivered as full JP65 profile suite (frame · sash · beading · mullion · adapter).
Key technical specifications include:
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.
