Casement Aluminium Window Profiles – Hinged Window Extrusions | Shengxin

Casement Aluminium Window Profiles are the workhorse of hinged window systems. A casement window opens outward or inward on side hinges, like a door, and our profiles are engineered specifically for that movement. The outer frame, sash, and glazing bead are designed as a matched set, with integrated hinge grooves, weather seal channels, and multi-point locking cavities that make fabrication straightforward and performance reliable. Whether the window opens left, right, or from the top, these profiles deliver a smooth, secure, and weathertight operation.

Made from 6063-T5 aluminium, the profiles are lightweight yet rigid, with multi-chamber hollow sections that improve thermal performance and structural strength. The hinge groove accepts standard casement friction stays and butt hinges without additional machining, while the Euro-groove slot (15/20 mm) is ready for espagnolette locks and shoot bolts. For energy-efficient projects, a thermal break version with PA66 GF25 insulation strips is also available, reducing frame Uf values to as low as 1.8 W/m²K.

Shengxin has over 30 years of aluminium extrusion expertise and manufactures these profiles entirely in-house — from billet casting to final anodizing or powder coating. This ensures consistent dimensions, clean sightlines, and a finish that lasts the life of the window. For a complete window package, see our insulated window frame system, which pairs these casement sections with matching hardware and gaskets.

Features & Benefits

• Purpose-built for hinged operation: Integrated hinge grooves and reinforced sash corners withstand years of repeated opening and closing without sagging or misalignment.
• Excellent weather sealing: Triple EPDM gasket channels (inner, centre, outer) create a continuous seal against wind and rain. The profiles are tested to EN 1026 for air permeability and EN 1027 for water tightness.
• Multi-point locking ready: The sash profile accepts standard espagnolette hardware, allowing shoot bolts and corner drives for secure multi-point locking on tall casement sashes.
• Thermal break option: A PA66 GF25 insulated version dramatically reduces heat transfer, making casement windows suitable for cold climates and energy-code compliance.
• Slim, clean sightlines: The sash and frame profiles are designed to maximise glass area while maintaining structural integrity, giving the window a modern, minimal appearance.
• Easy fabrication: All profiles share common glazing bead and gasket geometry, simplifying stock holding and workshop setup. We can also supply pre-cut and machined sections to your window schedule.

Casement Window Profile Components

Each casement window system uses the following matched profile types. All are extruded from the same alloy batch for colour and dimensional consistency.

All components can be supplied cut-to-length or fully machined with hinge cut-outs and locking slots per your fabrication drawings.

Technical Specifications

As part of our complete range of aluminum profiles for doors and windows, these casement sections can be ordered alongside matching fixed-light, tilt-turn, and door profiles for a consistent window suite.

Applications of Casement Aluminium Window Profiles

• Residential side-hung windows: The most common casement style, offering maximum ventilation and easy cleaning. Our profiles support sashes up to 1200 mm wide and 1800 mm high with standard hardware.
• Top-hung and awning windows: The same outer frame and sash profiles can be configured for top-hinged operation, ideal for high windows or areas where an outward-opening sash could be obstructed.
• French casement pairs: Double sash configurations with a central mullion are easily fabricated using our profiles, creating a wide, unobstructed opening when both sashes are open.
• Thermally broken casement windows: With the PA66 thermal break option, these profiles meet energy code requirements in cold climates while retaining the classic casement aesthetic.
• Commercial and institutional buildings: Durable, low-maintenance casement profiles are suitable for schools, offices, and public buildings where easy operation and long service life are required.

Casement Aluminium Window Profiles FAQ

Custom Casement Window Profile Solutions

If your project requires a custom frame depth, a unique sightline, or a specific thermal performance target, Shengxin's custom casement profile service can design and extrude profiles to your exact drawings, delivered ready for fabrication.

How It Works:

1. Send your drawing — 2D PDF/DWG or 3D STEP/IGES file showing the profile geometry and performance requirements.
2. Our engineers review — we assess extrudability, structural performance, and suggest optimisations for fabrication efficiency.
3. Receive a quotation — including die cost, unit price, and lead time.
4. Approve a sample — we extrude a trial section and send it for your approval.
5. Full production — consistent quality, delivered on schedule with full documentation.
