There is no standard size security gate because every opening has different measurements even if they look the same. We custom-make your security gate to fit the measurements we take on site and this contributes to the strength of the security barrier.

To give you a fair quote we need to measure the opening and quote according to the product you’ve chosen. Window and door openings all have different measurements, security risk levels, handles that have to be accommodated and different substrates for our products to be fastened to, so we really do need a site visit to quote accurately. Our quotes don’t carry any obligation and we’re happy to carry out a free security assessment of your entire property while we’re there.

No. Trellidor products can only be installed by Trellidor appointed franchises that are authorised to carry our specialised installation tools. Warranties are invalid if our products have not been installed by authorised technicians, including second-hand Trellidor barriers. If you are uncertain whether or not the person trying to sell you a Trellidor product is authorised to do so, please check with your nearest Trellidor franchise.

All Trellidor security systems carry a warranty in terms of quality, defective workmanship, materials and corrosion resistance, no matter where they’re installed. In RSA we also comply with the Consumer Protection Act. By following our suggested maintenance regime you will ensure maximum longevity of your barriers and the full validity of our warranty. It is essential to keep your receipted invoice in a safe place to use as evidence of your purchase should the need to claim arise after installation. Find out more about our warranties.

No responsible security barrier manufacturer should ever claim to have an impenetrable product. Given the right opportunity, thieves can always find a way to get into your home or workplace. Good quality, well-engineered security barriers, such as the Trellidor range, give you the best chance of either being alerted by an attempted break-in and able to call for help or to escape through an emergency exit route because they will hold up under attack far longer than poor quality or DIY barriers do. Take a look at the Trellidor security barrier range.
