Effective protection against unauthorised access
Our burglar and safety grilles are designed to provide a robust and reliable physical barrier in environments where high security is required. Manufactured in aluminium, stainless steel, or galvanised steel, the grilles can be tailored to meet specific project requirements in terms of size and configuration.
They can be installed as a complement to roof hatches, floor hatches, or access covers, or used as a standalone solution. The grilles are particularly suitable for protecting technical installations such as electrical systems, water and drainage infrastructure, and other critical assets where both security and accessibility are essential.
With flexible opening options—fixed, lift-out, or hinged designs—and the possibility of locking arrangements, these grilles offer a solution that combines functionality, safety, and long service life.
Our burglar and safety grilles are ideally combined with our range of roof hatches or access covers.

Can security grilles for hatches be customised?
Yes, security grilles can be custom-made in different sizes, materials, and designs to fit roof hatches, floor hatches, and access covers.
How are security grilles installed?
