Door & Window Grilles


Rivers Locking Systems manufactures heavy duty steel door and window grilles. Rivers security grilles are available in a variety of designs and are custom made to protect any door or window vulnerable to forced or unathorised entry.

Door configurations include, but are not limited to, single leaf swinging, double leaf swinging, single leaf sliding and double leaf sliding door grilles.  Window grilles can be face fixed or between jamb fixed.

Grille perimeter frames are generally fabricated from steel RHS section or angle.  Security bars are no less than 10mm solid square bar at approximately 110mm centres.  Steel sections are specified based upon the security risk, aesthetics and overall door leaf size.


Rivers door and window grilles are used in commercial and industrial buildings where unauthorised access is to be restricted or existing door and window security is inadequate.   Rivers security grilles have been used in government buildings, schools, retail stores, warehouses, distribution centres, factories, banks, office buildings, council amenities buildings, showrooms, shopping centres and alike.


Swinging door grille hardware includes heavy duty ball bearing hinges and pad bolts or mortice bolts.  Sliding door grilles utilise top & bottom tracks complete with guides & rollers.  Hardware is not applicable on fixed window grilles.


It is recommended that any externally mounted security grilles are hot dip galvanised.  Internal door grilles may be grey primed. Durable polyester powder coat can be applied in any standard Dulux colour upon request. Special colours are available.


Rivers security grilles are designed to be securely bolted to the surrounding structure using either security fasteners or dome head bolts that are fixed though the entire thickness of the wall.  Refer to sales staff in relation to installation.
