Buying Security Shutters – What to Look For

Security Shutters are growing in popularity in South Africa. Homeowners are looking for a home security solution that’s attractive and adds value while offering protection. Security Shutters tick all the boxes, but they can be expensive.

If you’re ready to invest in security shutters, you’ll want to get the most value for your money. While many shutter manufacturers offer discounts, you don’t want to compromise on your security. Here are some things to look for when you’re shopping around for security shutters.

Quality Materials

Security shutters are usually made from aluminium, a widespread metal that is lightweight yet strong. At House of Supreme, we use a high-grade aluminium alloy (6063-T6) to manufacture our Security Shutters. It is easy to extruded smooth yet complex shapes from this grade of aluminium. That’s why it’s used for window and door frames and of course, shutters.

Aside from looks, this grade of aluminium is strong enough to withstand 190 MPa (megapascals) of pressure. And thanks to a thin surface layer of aluminium oxide, it’s corrosion-resistant, which means it won’t rust or fade.

Designed for Strength

The strength in security shutters doesn’t only come from the type of metal used. A lot has to do with the design of the aluminium profiles or frame stiles. The stiles are the strips you see on the left- and right-hand side of the louvres, and they are connected to the top and bottom rails.

Thicker frames might be more secure, but they can also spoil the look of your shutters. To overcome this, House of Supreme has designed security shutter frames with a hidden ribbing. This adds strength to the frames while maintaining an elegant, ‘slimline’ appearance.

Security Shutter Features – Bolts & Louvres

Locks, bolts, and other security features are what set security shutters apart from decorative shutters. What you need to be aware of here, is the quality of these features.

For example, many security shutters have a two-way lock system. This consists of two bolts that, when you turn the key, shoot out of the frame into the top and bottom tracks to secure the shutter. Bolts made from an inferior material such as plastic or even aluminium won’t offer much resistance to a determined intruder. Stainless-steels bolts, like the ones we use in our security shutters, are far superior and offer a much tough barrier to criminals.

On our shutters, the top bolt extends 11.5 mm into the top frame and 16.5 mm into the bottom track. Together with tensioned rods, thicker walls and an internal structure designed for strength and stability, our security shutters are the best on the market.

If you’re concerned that criminals may be able to crowbar the louvres apart, that’s an area we’ve covered, too. The louvres on our security shutters are reinforced with hardened steel pins through the end-caps, securing the louvres the frame. As a result, the louvres may suffer a little damage from an attack, but they’ll never pop out of the frame.

Strong Details

Attention to detail is crucial when it comes to security because criminals will exploit even the smallest weakness to gain entry to your home. That’s why, on our security shutters, we use hinges with shouldered or tapered pins that cannot be removed or punched out to remove the panels. These hinges also have nylon inserts to ensure the panels open and close without making a sound. This is another example of how we combine strength, aesthetics, and practicality to produce a security shutter you’ll want in your home.
