How does the steel T-profile work?

Call usMessage us on WhatsApp in your language

The T-profile is a 4 mm T-shaped steel piece that is glued and screwed underneath the bottom slat of the shutter. Joined to the slat, it gives it the rigidity it lacks.

The key is the shape. A flat piece can be bent; a T, because of its shape, does not bend to either side. So, with the T joined to it, the bottom slat can no longer bend in the middle.

The profile works together with the bolts at the ends, which slot into the wall. The T stops the slat bending; the bolts stop it being lifted.

It is explained piece by piece in how the T-profile reinforcement works and in shutter security.
