How to fix gratings correctly
Gratings are used in many areas, for example as covers for light shafts, steps or as floor coverings in industrial halls. Good fastening is essential to ensure that gratings are secure and stable.
Types of grating fastenings
There are two main types of grating fastenings: clamps and direct bolting.
Clamps
Clamps are the simplest and most cost-effective way to attach gratings. They are hooked into the mesh of the grating and secured with a screw or bolt. Clamps are available in different sizes and designs so they can be used on gratings with different mesh widths and shapes.
Hook screws
Hook bolts enclose a support structure and secure the grating against shifting and lifting. Hook bolts are combined with a clamp top. Depending on the design of the hook bolt, a screw or nut is required for fastening.
Direct mount fastenings
Direct mount fastenings are screwed directly into the grating or the subsurface. They offer a high level of stability and safety, but are also somewhat more expensive than clamps. Direct screw connections are available in various designs, for example as drilling screws or set bolt fastenings.
Fastener sets
Fastening sets are combinations of clamps or hook screws that are tailored to the application and are provided pre-assembled or loose as a set.

Which grating fastening is the right one?
The choice of the right grating fastening depends on various factors, such as the size and type of grating, the support of the grating and the safety requirements. In addition, the intended use and location are decisive for the selection of the correct corrosion protection.
Safety fastening in fall areas
In areas where there is a risk of falling, an additional safety fastening is required. This prevents the grating from being moved or lifted off. Various fastening options are available for securing light shaft gratings, for example as chains, brackets or locks.
Installation of grating fastenings
The installation of grating fastenings is generally relatively simple. The exact procedure depends on the type of fastening. With clamps, these are hooked into the mesh of the grating and fixed with a screw or bolt. With direct screw connections, the screws or the set bolt fastenings are placed directly into the support.
Conclusion
Gratings should always be securely and stably attached. The choice of the right fastening depends on various factors. When installing grating fastenings, the exact procedure must be observed.
