Discover how professional manufacturing, German engineering, and global expertise come together to deliver windows and doors that last a lifetime.
When it comes to outfitting a luxury villa, a modern commercial building, or a high-end residential project, the quality of your windows and doors can make or break the final result. Aluminum windows and doors have become the go-to choice for architects, builders, and property developers worldwide — and for good reason. They offer unmatched strength, sleek aesthetics, and long-term durability. But finding the right manufacturing partner is just as important as choosing the right material. That is where ALPES comes in.
The ALPES Difference
ALPES is a professional system window and door manufacturer based in China, with a 100,000-square-meter production base and two major manufacturing centers in Foshan and Zhaoqing, Guangdong. With years of deep industry experience, ALPES specializes in high-end aluminum system windows, doors, sunrooms, and lift-up windows. The company exports to multiple countries worldwide, serving luxury residential and commercial projects across the Middle East, Australia, and beyond.
Whether you are a contractor sourcing for a large-scale development or a homeowner looking for premium custom solutions, working with a trusted
casement window manufacturer can make all the difference in project outcomes. ALPES brings factory-direct pricing without compromising on quality, giving you the best of both worlds.
Premium Materials and Precision Engineering
At the heart of every ALPES product is the 6060-T66 grade aluminum profile — an ultra-high-precision material that delivers superior structural rigidity and deformation resistance. Profile thicknesses range from 1.8mm to 2.5mm, meeting and exceeding the latest national standards. This is not commodity-grade aluminum; it is engineered material built for decades of performance.
Thermal performance is a key priority. ALPES employs multi-chamber thermal break systems with PA66GF25 insulation strips, achieving K-values as low as 1.3 on the AW90 Passive Window. This means exceptional energy efficiency — keeping interiors warm in winter and cool in summer while reducing heating and cooling costs. The dual-matrix eight-layer sealing system provides comprehensive protection against wind, rain, noise, and temperature extremes.

A Product Range Built for Every Project
ALPES offers a full spectrum of aluminum window and door solutions, each engineered with specific performance characteristics to match different architectural demands:
Casement Windows: The C120, C113, and C116 series feature outward-opening designs with nail-free mesh structures, full glue-injection corner reinforcement, and triple sealing systems. The C116 series boasts an ultra-slim 28mm frame and 22mm mullion for maximum visibility and a sleek, modern appearance.
Tilt and Turn Windows: The AW90 Passive Window achieves a remarkable K-value of 1.3 with 360-degree locking point distribution and an eight-layer sealing system. The AW113 series adds further versatility. For builders seeking the highest standards,
tilt and turn window manufacturers like ALPES deliver European-style functionality with Asian manufacturing efficiency.
Sliding Windows: The TS130 Side Press Window combines push-pull and swing hinge functionality with eight-point locking and 200kg load-bearing pulleys, offering space-saving operation without sacrificing sealing performance.
Sliding Doors: Four thermal break sliding door models — SL155, SL112/167, SL126/182(96), and SL126/182(75) — offer configurations from two to four tracks, with load capacities up to 400kg and single sash openings up to 7.5 square meters. As a professional
aluminum sliding window supplier, ALPES ensures every product meets rigorous quality standards before leaving the factory.
German Hardware and Rigorous Quality Standards
ALPES partners with world-renowned hardware brands to ensure every window and door operates smoothly, locks securely, and withstands decades of daily use. These partnerships include ROTO (Germany), Winkhaus (Germany, with 169 years of engineering heritage), CMECH (Red Dot Design Award winner, 30,000-cycle tested), and Wehag (Germany). The hardware is not an afterthought — it is integrated into the design from the start.
Quality is built into every step of the manufacturing process. The full injection-molding structural adhesive process creates seamless, monolithic corner structures. High-strength corner reinforcements with complete corner sealing add further structural integrity. The AW90 Passive Window has passed 240-hour salt spray corrosion resistance testing and demonstrates 5,000N shear resistance strength — numbers that speak to serious engineering commitment.
Global Project Experience You Can Trust
ALPES has successfully delivered projects for luxury villas and high-end developments in Saudi Arabia, Dubai, Australia, and across the Middle East. The company's ability to manufacture according to international building codes and adapt to diverse architectural requirements makes it a reliable partner for global builders and developers. Each project reinforces ALPES's reputation for delivering on time, on specification, and on budget.
Custom Solutions Tailored to Your Vision
Every project is different, and ALPES understands that. The company offers four standard color options — Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee — with custom color matching available upon request. Various insulated glass configurations with multiple tint and style options can be specified. From custom dimensions to specialized finishes, ALPES provides flexible solutions with competitive direct-from-factory pricing that eliminates middleman markups.
