Wrought iron security doors and custom made security doors by Trellidor Australia are a visible and practical deterrent against intruders for your home or business.

The security doors and security doors system are galvanised or zinc plated then powder coated for maximum protection against the suns rays and the oceans salt.

Protect and enhance your home with steel security doors. Either design your own or choose from Trellidor’s comprehensive range of 30 standard designs.
