When it comes to outfitting commercial buildings with windows that balance performance, aesthetics, and durability, ALPES stands out as a premier casement window supplier and system window manufacturer from China. With a 100,000 m² production base spanning Foshan and Zhaoqing, ALPES delivers high-end aluminum windows and doors engineered to meet international building standards for luxury residential, hospitality, and commercial projects worldwide.
Commercial properties demand windows that can withstand heavy daily use, large glass panels, and varying weather conditions — all while maintaining a polished appearance. ALPES designs its commercial aluminum window systems with exactly these priorities in mind. Every product is built using 6060-T66 grade aluminum profiles with thicknesses ranging from 1.8mm to 2.5mm, meeting and exceeding China's new national standards for structural integrity.
PA66GF25 multi-chamber thermal break systems deliver K-values as low as 1.3 (AW90 Passive Window), significantly reducing energy costs for commercial buildings.
Partnered with ROTO, Winkhaus, CMECH, and Wehag — all German-engineered hardware brands — ensuring 30,000+ operation cycles and long-term reliability.
Dual-matrix eight-layer sealing systems and full injection-adhesive corners deliver unmatched water tightness, wind resistance, and sound insulation.
Four standard colors (Ice Cream White, Aurora Gray, Starry Sky Gray, Brown Coffee) plus custom color matching to suit any architectural style.
ALPES offers a full lineup of commercial aluminum window and door systems, each engineered for specific functional and aesthetic requirements. From high-rise office facades to luxury villa developments, the product portfolio covers virtually every commercial application.
As a leading casement window supplier, ALPES offers three distinct casement window series: the C120, C113, and C116 outward-opening models. Each features 6060-T66 aluminum profiles with 1.8–2.0mm wall thickness, PA66GF25 thermal breaks, and premium German hardware. The C120 series includes a nail-free rolled press mesh structure and anti-pry lock points from ROTO, making it ideal for ground-floor commercial spaces where security is a top concern. The C116 stands out with its slim 28mm frame and 22mm medium mullion, maximizing glass area for panoramic views — perfect for showrooms and premium retail spaces.
For commercial projects that demand flexible ventilation and easy cleaning, ALPES tilt and turn windows are the solution. The flagship AW90 Passive Window achieves a remarkable K-value of 1.3, meeting passive house standards and delivering exceptional energy efficiency for climate-controlled commercial buildings. With 360° locking points, 240-hour salt spray corrosion resistance, and Winkhaus hardware (169 years of German engineering), these windows are built for performance and longevity. The dual-opening design — tilt mode for secure ventilation and full swing mode for egress and cleaning — makes them a practical choice for hotels, office buildings, and multi-story residential complexes.
The TS130 Side Press Window redefines what sliding windows can achieve by combining the space-saving advantages of sliding design with the sealing performance of casement windows. Its four-sided continuous sealing strip and side-pressure rubber seal deliver casement-level weather resistance, while the eight-point locking system and German ROTO hardware ensure security and smooth operation. With 200kg load-bearing pulleys and options for integrated glass railings and anti-theft grilles, this model is well-suited for hotel balconies, apartment buildings, and commercial spaces with limited exterior clearance.
As an experienced sliding door supplier, ALPES manufactures four heavy-duty sliding door series designed for commercial entrances, patio areas, and interior partitions. The SL155 Thermal Break Sliding Door features a four-track design with single sash dimensions up to 2800mm × 2600mm, creating opening areas of up to 7.5㎡ — ideal for resort lobbies and restaurant patios that need to connect indoor and outdoor spaces seamlessly. The SL126/182 series offers lift-sliding functionality with reinforced profiles up to 3.0mm thick in critical zones, handling large panel sizes up to 2.5m × 3.0m while maintaining wind pressure resistance and structural integrity.
ALPES manufactures all its commercial window and door systems according to international building codes, making the company a trusted partner for projects across the Middle East, Australia, Europe, and beyond. The company's track record includes luxury villa projects in Saudi Arabia, Dubai, and Australia — each requiring custom solutions tailored to local climate conditions, aesthetic preferences, and structural requirements.
