When a construction project reaches the glazing stage, the choice of an aluminum windows and doors partner can shape everything from the building envelope’s thermal performance to the final delivery schedule. For developers, contractors, and distributors managing residential or commercial projects, the difference between a transactional supplier and a true manufacturing partner is measured in quality consistency, communication, and long-term reliability.
ALPES, a system window and door manufacturer based in Foshan, Guangdong, China, has built its business around exactly this kind of partnership. With a 100,000 m² production base across two manufacturing centers in Foshan and Zhaoqing, the company produces premium aluminum system windows and doors for projects around the world.
What a Manufacturing Partner Should Offer
A project partnership is more than a purchase order. The right partner brings engineering depth, consistent quality, and the ability to adapt standard systems to project-specific requirements. ALPES supports this through:
- Materials that meet international standards. ALPES uses 6060-T66 grade aluminum profiles with thicknesses from 1.8mm to 2.5mm, meeting or exceeding new national standards. Multi-chamber thermal break systems with PA66GF25 insulation strips deliver K-values as low as 1.3 on the AW90 Passive Window.
- Hardware from trusted European brands. ROTO, Winkhaus, CMECH, and Wehag hardware are integrated into the systems, giving projects reliable operation and security performance.
- Customization without compromise. From profile color matching to insulated glass configurations, ALPES tailors each system to the project’s architectural and climatic demands.
A Product Range Built for Real Projects
Every project has different openings, orientations, and performance requirements. ALPES covers them with a focused product line:
- Casement windows. The C120, C113, and C116 outward-opening systems combine multi-cavity thermal break profiles with nail-free rolled press mesh and triple sealing for wind, rain, and noise resistance. As a casement window manufacturer, ALPES offers 1.8mm profile thickness options with ROTO transmission boxes and anti-pry lock points.
- Sliding windows. The TS130 side press window combines push-pull and swing hinge operation, saving indoor space while delivering casement-level sealing through a four-sided continuous sealing strip and an eight-point locking system.
- Tilt and turn windows. The AW90 Passive Window achieves a K-value of 1.3 with 360° locking point distribution, 240-hour salt spray corrosion resistance, and 5,000N shear resistance. Winkhaus hardware adds 169 years of German engineering to the system.
- Sliding doors. The SL155, SL112/167, and SL126/182 thermal break sliding doors support large openings up to 7.5 m², with 400kg load capacity pulley systems, dual-matrix eight-layer sealing, and options for glass railings and rolling screens.
For projects that need a dependable aluminum sliding window supplier or sliding door supplier, this range means fewer vendors to coordinate and a single quality standard across the whole building envelope.
How the Partnership Process Works
A well-run project partnership follows a clear path from first inquiry to installation support:
- Requirement definition. Share your project drawings, performance targets, and climate conditions. ALPES engineers review the specifications and recommend the right profile systems and glass configurations.
- Design and sampling. Custom color matching and glass options are confirmed, and samples are produced so the finish and hardware feel can be verified before mass production.
- Production with quality control. Production follows documented quality checks, from raw material verification to surface treatment and assembly, so issues are caught before units leave the factory.
- Packing and logistics. Units are packed for long-distance freight with protective wrapping and reinforced crates, minimizing the risk of transit damage.
- Installation support. Clear documentation and direct communication with the project team help ensure correct installation and a smooth handover.
Proven Experience Across Climate Zones
ALPES has delivered aluminum windows and doors for luxury residential projects in demanding environments, including villas in Saudi Arabia, high-end residences in Dubai, residential projects across the Middle East, and modern villas in Australia. These projects demonstrate the company’s ability to handle extreme heat, strong solar exposure, and architectural requirements that call for both performance and aesthetics.
