Buying aluminum windows and doors for a villa, apartment building, hotel, or commercial project is a bigger decision than it looks. The frame system, the glass package, the hardware, and the way the units are packed for export all affect how the building performs years after installation. For buyers who want a reliable supply at factory-direct prices, ALPES, a system window and door manufacturer based in Foshan and Zhaoqing, Guangdong, China, offers a practical route: custom aluminum system windows and doors manufactured to international building standards and shipped worldwide.
China has a mature supply chain for aluminum windows and doors, and Guangdong sits at the center of it. Factories there serve residential, villa, apartment, hotel, and commercial projects, which means buyers get more customization flexibility, clearer cost comparison, and access to different performance levels, from standard systems to high-performance thermal break aluminum windows. Working directly with a manufacturer such as ALPES removes the middle layers, so the price reflects the factory cost and the technical team can answer questions about profiles, glass, and hardware directly.
The more complete the information you send, the more accurate the quotation and the fewer surprises during production. Before you contact a supplier, prepare the following:
ALPES manufactures a full line of aluminum system windows and doors, so one supplier can cover the whole project. As a casement window supplier, the company offers the C120, C113, and C116 outward-opening systems, built with 6060-T66 profiles, thermal break insulation, and optional integrated mesh. For projects that need space-saving openings, the TS130 side press window combines push-pull and swing hinge operation to deliver casement-level sealing without taking up indoor space.
The tilt and turn line includes the AW90 passive window, which reaches a K-value as low as 1.3 with 360-degree locking point distribution and an eight-layer sealing system. On the door side, the SL155, SL112/167, and SL126/182 thermal break sliding doors handle load capacities up to 400kg and offer single sashes large enough for panoramic openings. Whether the requirement is a standard casement, a large sliding door, or a passive-house window, the range is designed to be configured to the project rather than forced into it.
The value of a window or door sits in the materials and the way they are put together. ALPES uses 6060-T66 aluminum profiles with wall thicknesses from 1.8mm to 2.5mm, meeting or exceeding the new national standards. The thermal break systems use PA66GF25 multi-chamber insulation strips, and hardware comes from ROTO, Winkhaus, CMECH, and Wehag, all German-engineered brands known for durability and smooth operation. Production runs across a 100,000 square meter facility with two centers in Foshan and Zhaoqing, and the company manufactures according to international building codes for export markets.
Custom orders are the norm rather than the exception. Standard frame colors include Ice Cream White, Aurora Gray, Starry Sky Gray, and Brown Coffee, with custom color matching available. Glass can be specified in various insulated configurations with multiple tint and style options, and screen mesh choices range from 40# and 80# stainless steel mesh to black high-definition anti-PM2.5 mesh. Buyers can also add glass railings, anti-theft grilles, and inward-opening mesh depending on the system.
A clear order workflow protects both pricing accuracy and production accuracy. A typical custom project with ALPES follows these steps:
For overseas projects, keeping records at key stages helps buyers follow the job status even when they are not in China. Production records may include frame fabrication photos, corner assembly details, glass preparation, hardware installation, and finished product photos. QC records cover quantity checks, dimensional logic, appearance, opening direction, labels, and accessories. Each unit is labeled to match the approved drawings, such as W01 and W02 for windows and D01 and D02 for doors, so the site team can identify every item quickly after unloading.
Export packing typically includes protective film on the aluminum profiles, corner protectors, foam or pearl cotton wrapping, extra glass protection, and wooden reinforcement for sea freight. For oversized sliding doors and large fixed glass panels, the glass and frame may be packed separately for transport safety, with installation guidance provided for the local team.
The biggest concern for overseas buyers is often installation after the goods arrive. Tell the factory early how the units will be installed and what the wall structure is, so the right fixing accessories and frame details are prepared before production. After arrival, unload carefully, check the quantity against the packing list, inspect for transport damage, and have a professional installer fit the units. Then test opening, closing, locking, and sliding before sealing between the frame and the wall to achieve weather tightness and waterproofing.
Procuring aluminum windows and doors from a manufacturer like ALPES means getting custom systems, verified materials, and factory-direct pricing from a single source. Whether you need an aluminium sliding window manufacturer, a tilt and turn window supplier, or a complete door package, the same technical team handles the whole order.
