7mm Diamond Security Doors
K&B Security Doors and Shutters' heavy duty 7mm diamond grille for security doors and security screens (also referred to interchangeably as security windows) is an affordable alternative to stainless steel .316 marine grade woven Supa Shield Security Doors.
It's a long-lasting security screen solution that provides a strong visual and physical deterrent to would-be intruders.
Hinged and sliding doors to suit both aluminium and timber applications are available, as are French, stacker, double-hung, awning and bi-fold doors.
We also stock decorative cast panel steel security doors.
All security screen doors manufactured by K&B have three hinges for added protection, are riveted to the aluminium door frame and made with solid aluminium corner stakes which strengthen the security doors ability to absorb impacts.
All of our products are custom-made at our Meadowbrook plant in Brisbane, Queensland, with the choice of single or three point locking systems (also known as triple locks).
All of our products are offered in an array of designs and colours to suit any taste, or match any décor.
Steel bars are a complete security solution as it is the strongest possible product with which to protect your home and keep your family safe.
K&B can supply and fit custom-made steel bars, security windows and security doors, factory direct in Brisbane, Toowoomba, the Gold Coast and Sunshine Coast.
All steel products are zinc-plated and galvanised (to prevent rusting and corrosion) before the powder-coat is applied.
