Indispensable for stability
Steel reinforcement profiles are essential to ensure that PVC windows remain stable and durable. These are located in the frame and sash and ensure optimum load distribution and dimensional stability.
The reinforced centre chamber plays a decisive role here: it transfers forces to the robust steel profiles in a targeted manner and ensures that the window functions reliably even after many years of use.
Reinforcing sections therefore not only make windows more stable, but also a reliable component for any building.
Sash profiles
The sash is the movable part of a window that can be opened and closed. It consists of a sturdy frame in which the glass is installed and must be able to withstand both high loads and the effects of the weather.
Our steel profiles for window sashes reinforce the sash frame and thus ensure greater stability and dimensional stability. They minimise the risk of deformation and increase resistance to weathering, ensuring the durability of the window.
- For side entrance doors
- For windows
- For balcony doors
- For lift and slide doors
- For front doors
Frame sections
The frame is the fixed frame of a window or door that holds the entire system in the wall opening. It forms the stable base on which the window sash or door is mounted.
Our frame sections provide additional stability and strength. They prevent deformation and increase the durability of the frame, even under heavy loads or in extreme weather conditions. This makes the entire construction more robust and resistant.
- For wide and narrow frames
- Especially suitable for front doors
- Perforation can be optionally incorporated
Post sections
The post is a vertical profile that connects window or door frames and provides additional stability, especially for large windows or multi-leaf doors. It takes on a load-bearing function and supports the load distribution within the system.
Our post sections increase the load-bearing capacity and torsional rigidity of the entire window system. They prevent deformation and guarantee a stable and durable construction, even with large or complex window elements.
- For wide and narrow posts/transoms
- Available in custom lengths
Coupling sections
Coupling is a connection between several window elements that makes it possible to realise larger glass surfaces or complex window constructions. It ensures that the individual window frames are stably connected to each other and that the entire system functions as a unit.
Our steel coupling sections increase the stability and strength of the connection. They prevent deformation and ensure that the coupling functions reliably even under high loads, making the overall structure durable and resistant.
- For concealed couplings
- Available in custom lengths
3D model before series production
Do you need a sample before going into series production? Modern 3D printing makes it possible. On request, you can receive a free, precisely manufactured 3D model of your section. We use the fused deposition process to produce models up to 30 cm long from bio-based PLA plastic.
