When you are planning a residential villa, a commercial building, or a large-scale development, the windows and doors you choose do more than frame a view. They control energy costs, protect occupants, and define the look of the whole facade. That is why more architects and developers are turning to a professional aluminum windows and doors builder who can deliver both performance and design in one package. ALPES, a system window and door manufacturer based in Foshan, Guangdong, China, has built its reputation on exactly that combination.
For years, ALPES has focused on one thing: engineering high-end, durable, and reliable custom aluminum system windows and doors. The company operates two production centers in Foshan and Zhaoqing with a combined manufacturing facility of 100,000 square meters, and exports to countries across the globe. Whether your project needs casement windows, sliding windows, tilt and turn units, or large sliding doors, ALPES offers a comprehensive product line built to international building standards.
One of the strongest reasons to work with ALPES is the breadth of the product range. Instead of juggling multiple suppliers for different openings, you can source every window and door from a single, reliable partner.
As a casement window manufacturer, ALPES offers outward-opening systems such as the C120, C113, and C116. These windows combine 6060-T66 aluminum profiles with multi-chamber thermal break systems, delivering K-values as low as 1.6. They feature nail-free rolled press mesh structures, triple sealing strips, and hardware from ROTO and CMECH, making them a dependable choice for homes and commercial buildings that need strong wind-pressure resistance and clean sightlines.
For spaces where outward opening is not practical, the TS130 side-press sliding window is an ideal solution. It pairs push-pull and swing hinge technology with a four-sided continuous sealing strip, achieving casement-level sealing performance without taking up indoor space. German ROTO hardware, 200kg load-bearing pulleys, and an eight-point locking system make it both smooth to operate and secure.
The AW90 passive window is the flagship of the tilt and turn range, and it is where ALPES shows what its engineering can achieve. With a thermal K-value of 1.3, 360-degree locking point distribution, and an eight-layer dual-matrix sealing system, it is designed for projects that demand the highest energy efficiency. As one of the leading tilt and turn window suppliers, ALPES equips these units with Winkhaus hardware backed by 169 years of German engineering, with optional C-Slot ROTO hardware.
For panoramic openings that connect indoor and outdoor living, ALPES supplies a range of heavy-duty sliding doors. The SL155 thermal break sliding door uses a 20-wheel self-balancing pulley system with a 400kg load capacity and supports single sashes up to 2800mm wide and 2600mm high. The SL126/182 series offers lift-sliding options with locally reinforced profiles up to 3.0mm and patented eave-style waterproofing. As a sliding glass door manufacturer, ALPES designs these doors for large daylight areas, strong wind-pressure resistance, and effortless operation.
The performance of any window or door starts with the materials. ALPES uses 6060-T66 grade aluminum profiles with thicknesses from 1.8mm to 2.5mm, meeting or exceeding the new national standards. The thermal break systems rely on PA66GF25 multi-chamber insulation strips, which keep interiors warm in winter and cool in summer while reducing condensation.
Hardware is another area where ALPES does not compromise. The company partners with internationally recognized brands including ROTO, Winkhaus, CMECH, and Wehag, all from Germany, ensuring that every handle, hinge, and locking point operates smoothly and lasts for decades. Combined with full glue-injection corner processes and triple sealing systems, these details add up to windows and doors that perform reliably in demanding climates.
Every project has its own architectural language, and ALPES supports that with flexible customization. Standard color options include Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee, with custom color matching available on request. A wide range of insulated glass configurations, including multiple tints and styles, lets you balance privacy, solar control, and aesthetics. Whether you need a specific profile width, a particular opening method, or a bespoke finish, ALPES can tailor the product to your specifications.
Scale matters when you are supplying windows and doors for large projects. ALPES manufactures in two production centers covering 100,000 square meters in Foshan and Zhaoqing, Guangdong, using advanced production technology and manufacturing according to international building codes. This combination of capacity and precision means consistent quality across every batch, reliable lead times, and competitive direct-from-factory pricing for importers, contractors, and developers.
ALPES products have been installed in luxury villa projects in Saudi Arabia and Dubai, residential developments across the Middle East, and modern villas in Australia. These projects demand high-temperature durability, superior thermal insulation, and compliance with strict local building codes. The fact that ALPES continues to be chosen for these demanding environments is a practical demonstration of the quality and reliability of its systems.
Choosing the right aluminum windows and doors builder comes down to three things: product quality, manufacturing capability, and the ability to customize. ALPES delivers on all three. With a complete product line, premium materials and hardware, a 100,000 square meter production base, and proven experience in international projects, ALPES is positioned to support everything from a single villa to a large commercial development.
