How advanced manufacturing, German-engineered hardware, and competitive pricing are reshaping the global fenestration supply chain
When it comes to sourcing premium aluminum doors and windows for residential or commercial projects, the global supply chain is increasingly turning its attention to China. With advanced manufacturing infrastructure, rigorous quality control, and competitive factory-direct pricing, Chinese manufacturers have emerged as formidable players in the international fenestration market. Among them, ALPES has established itself as a trusted partner for architects, builders, and developers worldwide — from the Middle East to Australia — delivering custom system windows and doors that meet the highest international standards.
Manufacturing Excellence at Scale
Operating from a 100,000 m² production base across two manufacturing centers in Foshan and Zhaoqing, Guangdong, ALPES represents the new generation of
china sliding door manufacturers that combine scale with precision. The company's factories are equipped with cutting-edge production technology, enabling consistent quality across diverse product lines including casement windows, sliding windows, tilt and turn systems, and heavy-duty sliding doors. This dual-facility setup ensures production flexibility and the capacity to handle large-volume orders without compromising on delivery timelines.
Material Quality That Meets Global Standards
What sets leading
tilt and turn window manufacturers apart is their commitment to material integrity. ALPES uses 6060-T66 grade aluminum profiles with thicknesses ranging from 1.8mm to 2.5mm — meeting and exceeding the latest national standards. The multi-chamber thermal break systems incorporate PA66GF25 insulation strips, achieving K-values as low as 1.3 on the flagship AW90 Passive Window. This level of thermal performance is critical for projects in both hot climates like the Middle East and cooler regions like Australia, where energy efficiency directly impacts long-term operational costs.

German Engineering, Global Partnerships
ALPES integrates hardware from world-renowned German brands including ROTO, Winkhaus — a company with 169 years of engineering heritage, CMECH (German Red Dot Design Award winner), and Wehag. These partnerships ensure that every window and door system delivers smooth operation, long-term durability, and enhanced security. For projects requiring
vertical bi-folding doors manufacture capabilities or custom configurations, the company's engineering team works closely with clients to develop tailored solutions that align with specific architectural requirements and regional building codes.
Proven Global Project Experience
ALPES has successfully delivered projects across multiple continents, demonstrating its ability to adapt to varying architectural styles, climate conditions, and regulatory frameworks. Notable installations include luxury villa projects in Saudi Arabia and Dubai, UAE, high-end residential developments across the Middle East, and modern aluminum window and door systems for Australian villas. This diverse project portfolio underscores the company's capability to serve both luxury residential and commercial markets globally.
Comprehensive Product Range
The casement window lineup includes the C120 outward-opening system window with a nail-free rolled press mesh structure and ROTO transmission box, the C113 featuring full glue-injection process with CMECH hardware, and the C116 with an ultra-slim 28mm frame and optional German Wehag hardware. Each model incorporates triple sealing systems, multi-chamber thermal break designs, and 304 stainless steel high-load hinges.
The TS130 sliding window combines push-pull convenience with casement-level sealing performance through its side-pressure mechanism, supported by German ROTO hardware, 200kg load-bearing pulleys, and an eight-point locking system. It also offers extended functions including inward-opening sash mesh, integrated glass railing, and anti-theft grille options.
The AW90 Passive Window achieves an industry-leading thermal K-value of 1.3 through its dual-matrix eight-layer sealing system, making it one of the most energy-efficient aluminum windows available. With 360° locking points and Winkhaus hardware, it delivers both thermal performance and security. The AW113 series complements this with a versatile tilt and turn configuration suitable for a wide range of architectural applications.
For door applications, the SL155 thermal break sliding door offers a 400kg load capacity with a 20-wheel self-balancing pulley system and single sash dimensions up to 2800mm × 2600mm. The SL126/182 series features locally reinforced profiles up to 3.0mm in critical zones, patented eave-style waterproof design, and 27A super large insulating glass with inert gas filling for superior thermal efficiency.
Customization Without Compromise
Every project is unique, and ALPES embraces this reality with extensive customization options. Standard color choices include Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee, with custom color matching available for bespoke architectural requirements. Glass configurations range from standard insulated glass to specialized tint and style options, all configurable to meet specific thermal, acoustic, and aesthetic needs. The company also offers various screen mesh options including black high-definition anti-PM2.5 mesh and stainless steel mesh in multiple grades.
