Security grill doors: the most durable solution

Well-suited to both doors and windows, and to both commercial and industrial purposes, a protective grille helps safeguard your business or your company’s buildings against any intrusion.

Protecting your windows

In areas that are vulnerable or prone to intrusions, windows represent a potential danger to the security of your premises if they aren’t equipped with a good anti-intrusion system. If you have windows that open directly onto the street or that are at ground level, it’s essential to install protective grilles! For added security, we also recommend outfitting the doors to a warehouse or shop with protective grilles, since they’re also likely to be broken. While you might think that grilles make your building look like a prison, they’re now designed to look more attractive, coming in several different models and often custom made according to your needs. It’s also possible to choose more or less ventilation depending on your field of business. Generally speaking, a protective grille for a window consists of several vertical bars spaced 12 cm apart. They are then welded to around two horizontal bars which are themselves attached to the wall. For shop or warehouse doors, there are sliding lattice-style protective grilles that are just as strong.

To choose a protective grille, you should consider the material used to manufacture it. The best materials for a reliable and weatherproof grille are:

Iron and wrought iron

  • Sturdy
  • Elegant
  • Customizable if desired
  • Durable

An incomparably strong material, iron or wrought iron offers a wide variety of protective qualities for buildings. As the basic element of steel and cast iron, it’s the most flexible metal for manufacturing items such as protective grilles. Used to manufacture the bars, iron is an unparalleled material that combines security and aesthetics and is simply impossible to break.

Steel

  • 100% recyclable
  • Easy to paint
  • Doesn’t rust
  • Strong and durable

Just as resistant as its big brother iron, steel also lets you customize your protective grilles. While it’s naturally rust-resistant, it should still be protected against corrosion and is therefore not recommended in coastal areas or regions that experience harsh weather.

Aluminum

  • Light
  • Durable
  • Strong
  • Doesn’t rust

Resistant to changing weather and naturally rust-proof, aluminum is often preferred. It also happens to be much lighter than – but just as strong as – steel and iron. The final argument in favour of aluminum: it’s often cheaper than other materials.

Tips

For maximum protection for your windows, the iron or steel bars should be firmly attached or anchored to the wall to a depth of at least 5 centimetres so that they’re inaccessible.

In addition, to ensure the longevity of your protective iron grilles, you can apply one or two coats of rust-proof paint before the final installation, then repeat the operation once a year!

Now that you have some idea of the most suitable material for your needs, you can choose a protective grille. They’re available in kits, ready-to-install, or custom-made, depending on the specifics of your premises. Finally, you just have to measure the exact dimensions and choose the installation type according to the place to be protected.
