Our TUFF-DOR collection provides LPCB (Loss Prevention Certification Board) security doors certified to LPS 1175 SR2, SR3 and SR4 as required.

TUFF-DOR 3.1 is certified to SR3 (Issue 7) to defend against opportunist attacks. This includes deliberate forced entry using a wide selection of attack options, including a gas torch, scissor jack, and a pad saw.

Our ultimate security door – TUFF-DOR 4.1 – is certified to SR3 (Issue 7). Testing includes replicating experienced attempts of forced entry using heavy duty tools, such as a disc grinder, jigsaw, and a sledgehammer.

Each TUFF-DOR is specially constructed to individual project requirements, with every door featuring internal reinforcement in strategic locations. As such, our TUFF-DOR range has been installed in a range of industries and environments including Government and defence buildings, airports, emergency service premises, financial services and high value retail outlets.
