Made to Measure Square Hole Grilles
Designs and Uses

Cast iron grilles can be used for either drainage, as gutters or for ventilation. If used for vents they can be fitted externally or internally and either built into walls (either brick or stone) to fit flush with the wall surface and secured in place with mortar or plaster. We can also drill them so they can be screwed to the wall to fit over a hole or for added security were the grille is mounted flush with the brickwork.

We do sell a lot of these grilles to go over round ducting holes used as outlets for various extractors from the kitchen, bathroom and even industrial areas. We have a guide to download that shows various size grilles over different sized bore holes available here.

The grilles are supplied undrilled.
We can drill these grilles at a cost of £5 per grille with 5 mm diameter holes, countersunk to take securing screws (not supplied) but please be aware the width of the border along the sides is quite narrow.
Therefore we drill the grilles within the top and bottom borders as close to the corners as possible.
ITEM - Drilling

Drill 4 holes in corners of square hole grilles
 
5mm hole + countersunk


£5 per grille

(Please alter quantity to match number of grilles requiring drilling)


Please Note

 
The photographs on the right and below show examples of 5" (127mm) gratings cut to various lengths (clearly showing 5 rows of holes).

The grille we make for you is unique - it won't be made until you order it. Therefore, apart from these illustrations, we do not have photographs of the exact grille to show you.

Customers can gain a good idea of how their grille will look when it is finished. This illustration shows three  5" (127mm) square hole grilles cut to various lengths and the specifications below that show the number of rows, hole sizes and grille thickness for all the grille heights available ranging from 4" 100mm up to 15" 380mm.

British Designs and British Castings

All our cast iron grilles shown here are made in the UK, they are cast in long lengths in foundries in Scotland and cut to size and painted in our workshop in Devon, England. 

All purchases made from The Cast Iron Air Brick Company  support British manufacturing...........

Because all our products are made in UK





Painted Grilles

Our cast iron products contain iron, nearly 100% iron to be precise and this iron will rust if it isn't kept protected from moisture and air.  These grilles are supplied primed and then painted using a two-part professional epoxy black gloss paint which will need repainting from time to time.
