Colonial Castings

Colonial CastingsColonial Castings is an Australian owned company that has been making quality safety screen panels to suit safety doors for over 20 years. Rust will never be a problem as all door inserts are gravity die cast in 100% recyclable aluminium, which is also known for its durability and strength.

The frames are constructed from extruded aluminium.

To capture that added touch of personal style and individuality, we offer you a wide choice of colours in a hardy powdercoated finish. Naturally the powdercoating is covered by a 24 month guarantee. To extend the life of the surface we recommend doors should be washed down regularly especially in salt water environments.

As a Invisi-Gard dealer we have the distinct advantage of being able to incorporate the advanced qualities of Invisi-Gard into your preferred Colonial Castings safety doors to provide added security as well as individuality. Click on the link to view a brochure.
