Custom Aluminum Sliding Window
Aluminum casement doors are known for their clean lines, reliable hinged operation, and excellent sealing performance. They open inward or outward through a sturdy casement door frame, providing wide ventilation, strong wind resistance, and effective noise and temperature insulation. As a professional manufacturer, HTS-ALU specializes in custom aluminum casement doors and offers a full range of design choices—from slim modern frames to elegant French-style options and contemporary all-black minimalist looks.
Our product range includes various aluminium casement door systems—from lightweight models ideal for bathrooms and interior spaces to heavy-duty large-format doors for patios, balconies, and main entrances.
Choose from anodizing, powder coating, electrophoresis, PVDF, or realistic wood-grain textures. Classic colors include black, white, bronze, champagne, and timber tones to suit modern, French-style, or minimalist narrow-frame designs.
Available enhancements include thermal-break aluminum profiles, insulated double glazing, laminated safety glass, and advanced laminated + insulated triple-layer units for improved energy efficiency, sound insulation, and security.
HTS-ALU designs and manufactures casement glass door systems tailored to your needs—covering size, style, opening direction (in-swing or out-swing), hardware selection, glazing configuration, and complete casement door frame integration for both interior and exterior applications.
Types of Aluminum Casement Doors
Aluminum casement doors are available in several opening styles to fit different room layouts and architectural needs. Popular options include inward-opening and outward-opening designs, along with larger casement patio doors that provide generous views and convenient exterior access. Depending on the project, you can also choose narrow-frame styles for a modern minimalist look, full-glass designs for maximum daylight, or divided-lite configurations for a more traditional aesthetic.

Applications of Aluminum Casement Doors
Aluminum casement doors are suitable for homes, apartments, offices, villas, and commercial buildings. They work well in bedrooms, kitchens, and study areas as interior door casement solutions, while their strong resistance to weather makes them ideal exterior door casement options for balconies and terraces. Large openings—such as casement patio doors—enhance daylighting and outdoor connectivity in modern architecture.
