Collapsible Security Grilles

Collapsible Security Grilles

Security is a concern to everyone these days. Be it at work, when travelling and of course at home. We always want to ensure that our homes and treasured possessions are protected, but the primary concern is to protect our families. Since criminals get more sophisticated and determined, we always aim at reviewing our ideas of security.

Do you think electrical devices are offering you the best security? Well, yes, but this is up to a point. These devices may alert you or your security providers but the question is how long will it take for a response? Before help can reach you, the attack can be over, and your valuables taken or worse, someone might be injured.

Therefore, your solution is to have effective physical barriers that can be used together with the electrical system. This will help keep everything and everyone in your home or workplace safe. For this reason, here at KP Engineering we offer you the best and high quality security grilles.

Internal Concertina Grilles

These are door grilles or window grilles that are fitted from the inside of the house. This can be retractable window security grilles, retractable sliding grilles, doorway grilles, steel folding shutters or window grilles.

These products are made of top quality galvanised steel. Moreover, they are powder coated; hence, the products are resistant to scratching, chipping or any other wear due to the thermal bonding that they undergo.

I was very fortunate to find and use KP Engineering to design, make and fit some balustrades and a handrail to some steps that I have which seperate the top part of my garden from the bottom. Contact was extremely easy and the whole job was managed with ease by Ketan. The measurements were exact and included the curvature of the two top balustrades. The fitting was also managed extremely efficiently and the guys who did the work were extremely polite, tidy and despite the rain completed the work quickly. I couldn't be more delighted with the end result. I wasn't aware that my garden could be improved so much with the addition of the railings. Overall, I have no hesitation in saying that this Company does what it says, on time, efficiently and with a great design team as well.

KP Engineering Works Ltd were a pleasure to work with from the outset through to completion. They spent good time ensuring the measurements were perfect, and kept us up to date with each element of the design, build and installation. The product looks great and it really is built to a high quality, with high quality fixings mounting to the wall. I highly recommend working with the KP Engineering team.
