As a professional manufacturer with 35 years of experience in the field of aluminum profiles for doors and windows, we have developed the core product of the Sliding Window Series – the balcony and kitchen aluminum heavy-duty sliding door Aluminum Profile system for high-frequency use scenarios such as balconies and kitchens. This product line strictly follows the international manufacturing standards of Aluminum Profiles For Windows And Doors, providing durable and systematic solutions for overseas buyers.

Ultra-quiet transmission system

Adopting automotive-grade double-bearing pulleys and matching German imported EPDM sealing strips (EPDM), the industry-leading level of opening and closing noise value ≤25dB is achieved. The measured data is 63% lower than that of traditional sliding doors, which is particularly suitable for residential kitchens and viewing balconies that require a quiet environment.

Engineering-grade structural strength

The 1.4mm Thermal Break aluminum profile frame is strengthened by T5 heat treatment, with a cross-sectional moment of inertia of 182cm³/m and a vertical load bearing capacity of over 1200N/m². With 4mm tempered glass (compliant with EN12150 standard), the overall wind pressure resistance level meets the ASTM E330 Class 4 certification requirements.

Long-term weathering protection

The surface treatment adopts a three-coat and two-bake process, with a film thickness of ≥45μm, and passes the 3000-hour neutral salt spray test (far exceeding the ultra-high precision requirements of GB/T5237). The original nano-ceramic coating technology ensures that the ΔE color difference value is ≤1.5 (ISO 7724 standard) after long-term use.

Systematic waterproof design

The high and low rail structures achieve an 8° drainage slope, and are combined with 304 stainless steel diamond yarn (mesh density 200 mesh) to form a double waterproof barrier. The built-in water guide groove in the track can quickly discharge 200ml/min/m of accumulated water, perfectly coping with heavy rain weather.

This series of aluminum profiles can be seamlessly connected with the Casement Window Series casement window system, supporting highly customized combinations. The base material is compatible with surface treatment processes such as powder coating and fluorocarbon coating, and a full range of RAL color cards are available.

Each batch of profiles is controlled by the ISO 9001 system and is equipped with a traceable 18-digit material code. The tolerance of key dimensions is controlled within ±0.15mm (GB/T 14846 AA grade standard) to ensure efficient assembly at global project sites.

Our Aluminium Profiles For Windows And Doors product line has been successfully applied to more than 3,000 engineering projects in North America, the Middle East and other places. We can now provide full-chain ODM/OEM services from profile extrusion, surface treatment to hardware matching, and support customized exclusive technical solutions according to project requirements.
