Why choose TI for your commercial security grilles?

10,947 businesses have already chosen us, and we want you to choose us too – and we promise we won’t let you down.

As a small business, security grilles may not be your first priority, but they can add an extra element of protection and also act as a deterrent to burglars. If you have valuable equipment in your offices such as computer systems, security grilles may be required by your insurance company – plus they’re much cheaper in the long run than inflated policy costs or replacing stolen items.

When you choose TI as your security partner, we’ll make sure you get the most cost-effective and appropriate commercial security grilles for your individual requirements, while also offering many other benefits:

  • Speed: we provide free surveys, fast and transparent quotations and ensure your security grille installation or upgrade suits your timescale.

Your small business security grilles – features and benefits

From brand new commercial security grilles to installation upgrades, we have the technical know-how to give you the very best experience…

  • Grilles for commercial premises

    Our grilles are perfect for commercial applications such as business offices, preventing access through windows and doors.

  • Fixed security grilles

    Cheap to install, these static grilles are ‘jail bar’ style and are fitted inside the windows – they reduce some of the incoming light though, so for a brighter and less intrusive solution, you may prefer the expandable variant.

  • Expandable security grilles

    expandable grilles are often used in office parks and larger commercial units. They are fully lockable from inside the windows or doors but can be unlocked and slid open during working hours to ensure a nicer and brighter environment.

  • Comply with insurance requirements

    If you have computers or valuable items in your premises, you may be required to have security grilles installed – we’ll make sure you’re fully compliant.

  • Keep windows open – but secure

    Some fresh air in the working environment is great for productivity, and security grilles allow you to keep the windows open if you wish, while still keeping your offices secure.

  • Measure and price your security grilles

    To measure your grilles and get an instant price, please refer to the measuring guide and price list. If you decide you want to purchase, let us know and we’ll come along and take final, accurate measurements. Please note that prices don’t include any alterations/building works that may be needed, but we’ll provide a quote for this once we’ve visited your premises.
