Our security grilles are very simple to fit and come hot dip zinc galvanised as standard. They are heavy duty and are a true deterrent to unwanted visitors!
The galvanising process undertaken is completed to British Standard BS EN ISO 1461 and offers our products superb protection against corrosion. This process is far superior to standard wet spray primer systems and will stand the test of time.
We also powder coat in-house, and we offer a range of colours allowing you to match the grilles to your windows.
If you choose to have your grille powder coated, we will galvanise the grille prior to powder coating process as standard.
PRODUCT DETAILS
The grilles are fully welded and made from strong 40mm x 8mm thick Mild Steel to create the frame and anti- spread bracing bars. The infill bars are 12mm solid round steel and are also fully welded. The anti-spread mid bars are fully drilled allowing the infill bars to pass through them. The bars are then again fully welded offering maximised strength and a neat finish.
The bars are spaced at gaps no greater than 100mm in line with building regulations.
The laser cut mounting tabs are fully welded and have a 12mm I/D hole to allow for M10 fixings into a wide variety of materials such as brick, wood and blockwork.
The moutings on the grille are set with a 60mm spacing between the back of the grille and the face of the mouting which will allow
windows to be opened to vent. If you require a large spacing please let us know and we can quote for this.
CHOOSING YOUR SIZE
Firstly measure the opening width and the opening height. (These are the measurements of the window opening in the brickwork)
STEP 1 -
Measure the width of your window reveal and add at least 150mm (15cm) to this measurement to make sure you have adequate space either side of the opening to allow for a secure fixing.
STEP 2-
Measure the height of the opening and select the closest height from our range to suit.
