Steel grills for windows and doors

Window Grills & Security Grilles

Window grills are steel bars or grilles fitted to a window to stop break-ins and damage while still letting the light in. We make them to measure for homes and businesses and fit them from our base in Horwich, Bolton, across Greater Manchester, Liverpool, Merseyside, Preston and the rest of the North West.

What we do

Window Grills & Security Grilles We Manufacture & Fit

Steel bar grill fixed over a white sash window in Wavertree, Liverpool

Fixed Window Grills

Steel bar grills fixed over the outside of a window. In Wavertree, Liverpool, we fabricated and fitted three high-strength window grills to a house.

Sliding Security Grilles

Steel sections joined so the grille slides aside out of sight, behind blinds or curtains, during the day. At night it pulls across and locks.

Grilles For Doorways

Sliding grilles for doors can be made with a hinged lift-up track, so there is no rail left across the floor to trip over when the grille is open.

Grills For Businesses

Grills for shop, office and unit windows that need protecting overnight, manufactured to fit each opening.

Window Security Grills That Still Let The Light In

Physically protecting windows and doors is one of the most effective ways to put off burglars, thieves and vandals. A grill does that without boarding the window up, so the room still gets daylight.

Window grills are being used more and more on local houses and businesses. We make each one to measure from steel sections, so it fits the window it is made for.

Window Grills Or Window Shutters?

A grill keeps intruders out and lets light and air through. Where a window keeps getting broken, a roller shutter covers the glass completely. For the RSPCA clinic in Wigan, which was regularly being broken into, we fitted roller shutters to all the windows and doors.

If you are not sure which suits your building, we can look at the windows and advise.

Cost

How Much Do Window Grills & Security Grilles Cost?

Grills are manufactured to measure, so the price depends on the windows. These are the main things that change it. We give free, no-obligation quotes.

  • Factor 1

    Number & Size Of Windows

    More windows, or larger ones, need more steel and more fabrication time.

  • Factor 2

    Fixed Or Sliding

    A sliding grille that folds away and locks has more parts than a fixed bar grill.

  • Factor 3

    Doorway Grilles

    A hinged lift-up track for a doorway adds to the price of a standard grille.

  • Factor 4

    Locking

    A sliding grille needs a lock so it can be secured shut at night.

  • Factor 5

    Fixing & Access

    What the grill fixes into, and whether upper windows need ladders or access equipment.

FAQs

Window Grills & Security Grilles: Your Questions Answered

The questions customers ask us most. If yours isn't here, give us a call.

Do window grills block the light?

No. A grill is made of steel bars or sections with space between them, so light still comes in. A sliding grille can also be pushed aside out of sight during the day.

Can a window grill be opened?

Yes, if you choose a sliding grille. It slides aside behind blinds or curtains during the day and pulls across and locks at night. Fixed grills stay in place.

Can you fit grills to doors as well as windows?

Yes. Doorway grilles can be made with a hinged lift-up track so there is no rail across the floor to trip on.

Are window grills manufactured to measure?

Yes. We fabricate each grill from steel sections to fit the window or door it is made for.

Do you fit window grills on houses?

Yes. We fit them to homes and businesses. In Wavertree, Liverpool, we manufactured and fitted three high-strength grills to a house.

Where do you fit window grills?

Across the North West, including Greater Manchester, Liverpool, Merseyside and Preston, from our base in Horwich, Bolton.
