When a project needs aluminum windows and doors, the usual route means juggling several suppliers — each with its own catalog, its own quality bar, and its own lead time. ALPES was built to remove that hassle. As a China-based system window and door manufacturer, ALPES runs what is effectively a one-stop aluminum windows and doors mall: a single source for casement windows, sliding windows, tilt and turn windows, sliding doors, swing doors, folding doors, entry doors, and sunrooms, all produced to the same consistent standard under one roof.
The idea behind the ALPES product mall is simple: instead of matching different window and door types from different factories, you work with one team that designs, manufactures, and delivers the full set. That matters more than it sounds. When the casement windows, sliding doors, and entry doors on a project all come from the same production line, the profiles match, the finishes match, and the hardware behaves the same way across the whole building. It also simplifies procurement — one quotation, one set of drawings, one delivery schedule, and one point of contact from design to installation.
The range covers the openings that appear in almost every residential and commercial project. On the window side, there are outward-opening casement windows, space-saving sliding windows, and European-style tilt and turn windows. On the door side, the catalog includes heavy-duty sliding doors, swing doors, folding doors, and secure entry doors, plus sunrooms for projects that want a year-round indoor-outdoor space.
Windows are where most projects start, and the ALPES range is built around three opening styles that suit different rooms and climates.
Casement windows. As a casement window manufacturer, ALPES offers outward-opening systems in three frame widths — the C120, C113, and C116. All three use 6060-T66 aluminum profiles with 1.8–2.0mm wall thickness and PA66GF25 thermal break strips. The C120 adds a nail-free rolled press mesh structure and an integrated door-and-window design that switches between modes instantly. The C113 uses a full glue-injection process with CMECH hardware that has been tested for 30,000 cycles. The C116 keeps a slim 28mm press line and a 22mm mullion to maximize the view, with 304 stainless steel high-load hinges and an easy flat-channel drainage system.
Sliding windows. For rooms where an outward-opening window is not practical, the TS130 side press window combines push-pull and swing hinge action, so it opens without taking up indoor space. A four-sided continuous sealing strip gives it casement-level sealing, and German ROTO hardware, 200kg load-bearing pulleys, and an eight-point locking system keep it secure. It is a common choice for kitchens, balconies, and high-rise apartments.
Tilt and turn windows. The AW90 Passive window is the flagship of the tilt and turn windows range, reaching a thermal K-value as low as 1.3. It combines a 360-degree distribution of locking points, a dual-matrix eight-layer sealing system, and Winkhaus hardware from Germany, backed by a 240-hour salt spray corrosion test and 5,000N shear resistance. The AW113 series rounds out the collection for projects that need a more standard tilt and turn profile.
Doors carry the heaviest traffic and the biggest openings, so the ALPES door range is engineered around load capacity, sealing, and smooth operation.
Sliding doors. As a sliding door supplier, ALPES offers four main systems. The SL155 thermal break sliding door uses a 20-wheel self-balancing pulley system with a 400kg load capacity and supports a single sash up to 2,800mm wide and 2,600mm high, opening an area of up to 7.5 square meters. The SL112/167 heavy-duty system drives sashes of up to 220kg with a 45mm high-ｄｒｏｐ bottom track for instant drainage. The SL126/182 series comes in two versions — a 96mm sash for maximum daylight area (up to about 7 square meters per sash) and a 75mm narrow-edge version with a patented 38mm slim frame for panoramic views. All sliding doors feature multi-point locking and continuous four-side sealing.
Swing, folding, and entry doors. Beyond sliding systems, the catalog includes swing doors for balconies and private entries, multi-panel folding doors that tuck away to open a room to a terrace, and entry doors with anti-theft locking and thermal break insulation. These complete the door collection so a single supplier can cover the whole building envelope.
For projects that want more than a window or a door, ALPES also builds all-season sunrooms. These structures filter UV light while letting in soft natural daylight, creating a comfortable space that can be used year-round. Combined with the window and door lines, they make the ALPES mall a genuine one-stop solution for the full exterior envelope.
The consistency across the product range comes from shared materials and partners. All profiles are 6060-T66 grade aluminum with thicknesses from 1.8mm to 2.5mm, meeting or exceeding new national standards. Thermal break systems use PA66GF25 multi-chamber insulation strips, helping windows reach K-values as low as 1.3. Hardware is sourced from established European brands — ROTO, Winkhaus, and Wehag from Germany, and CMECH — so the moving parts match the quality of the frames. Standard finishes include Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee, with custom color matching available on request.
Buying the whole package from one factory brings advantages beyond convenience. ALPES operates a 100,000 square meter production base across two centers in Foshan and Zhaoqing, Guangdong, which gives the capacity to handle large projects and to keep schedules moving. Products are manufactured to international building codes, drawing on experience in markets from the Middle East to Australia. Because you buy directly from the factory, customization — sizes, colors, glass types, and hardware — is handled in-house, and pricing stays competitive without a middleman.
That experience shows up in real projects. ALPES has delivered luxury villa projects in Saudi Arabia and Dubai, residential developments across the Middle East, and modern villa projects in Australia, where thermal performance and security requirements are strict. Each of these projects pulled multiple product lines from the same catalog, which is exactly how the mall is meant to work.
Choosing windows and doors is rarely a single-product decision. The ALPES aluminum windows and doors mall exists so that architects, builders, and developers can specify the entire opening package — casement, sliding, and tilt and turn windows; sliding, swing, folding, and entry doors; and sunrooms — from one manufacturer with one quality standard. If you are planning a project and want to compare options across the full range, contact the ALPES team for a quotation and let the product range speak for itself.
