Flat steel is a simple and fast solution for the reinforcement of glass rebates. It’s unavoidable for structural reasons, particularly when using triple glazing or for particularly large elements. The use of flat steel further improves the structure in the direction of the wind load, what is an important aspect in the construction of windows for many applications.

The replacement for flat steel developed by Gebhardt-Stahl is the pre-perforated alternative to conventional glass rebate reinforcements with flat steel. Our flat steel replacement even stabilizes large elements with triple glazing.

Reinforcement profiles are necessary for structural reasons and in many cases, they are also required for screw connections in the frame. Sometimes, however, it is advantageous when there’s no need to drill through the steel: the drilling process is faster, the drills have a significantly longer service life, and no hot swarf (which can damage the PVC) is removed.Even in such cases, in order to avoid making compromises in terms of the structure, Gebhardt-Stahl offers “handle-free” steel reinforcements as a substitute for standard sash reinforcements.

Large windows often have to deal with structural problems. The same thing also occurs with larger PVCu windows with roller shutter housings. In order to remedy this situation, we have developed stiffening elements, which give the elements the required stability.
