Our CrimeShield Perforated Window Security Mesh is manufactured to order, with a typical lead time of 3–4 weeks from order confirmation and final specification. Each panel is made to measure to suit the required opening, fixing arrangement and frame finish.

Lead times may vary depending on order quantity, panel sizes and bespoke frame colours. Where a specific BS or RAL colour is required for the aluminium frame, additional manufacturing time may be required. We will confirm the expected lead time at quotation or order stage.

Typical installation methods include:

• Reveal Fix – Installed within the structural opening

CrimeShield panels can also be supplied on a supply-only basis, subject to the installer ensuring suitable fixings and installation methods are used for the supporting structure.
