Heavy Duty Security Shutters

Where the highest level of security is paramount, the following security shutters are accredited by some of Europe’s leading regulators, including SBD (Secured by Design) and LPS1175 security rated levels 1-4. 

The LPS1175 test stipulates the allowable toolset and minimum time at each security rating level to prevent forcible entry through a building element.

The test (carried out by the Building Research Establishment) measures the time to make a hole big enough to get a person through (minimum of an elliptical shape 400mm x 225mm). It must be stressed that the test is carried out by individuals who already know the product inside-out – including any “weak spots”.

These ratings will generally be rated SR1-5. Please see below for a description of what each rating will protect you against:

SR1: Opportunist attack by bodily force using minimal tools (e.g. screwdriver, knife, pliers, etc) for 1 minute

SR2: More determined opportunist attack with tools of a higher mechanical advantage (e.g. SR1 tools plus bolt cutters, claw hammer, drill, etc) for 3 minutes

SR3: Deliberate forced entry of protected premises using bodily force and a selection of attack options (e.g. SR2 tools plus short axe, chisels, crowbar, gas torch, etc) for 5 minutes

SR4: Experience attempts at forced entry with higher tool levels (e.g. SR3 tools plus felling axe, sledgehammer, steel wedges, disc grinder, jigsaw, etc) for 10 minutes

Due to the nature of these shutters, they must be installed using certain fixings and in very specific ways in order to achieve the LPS1175 security rating
