LPS1175 SR3 Heavy Duty Steel Roller Shutter
Our steel shutters go up to level 4 whilst our aluminium versions will reach level 2. Please be aware, due to the nature of these shutters, they must be installed using certain fixings and must be installed in very specific ways in order to achieve the “LPS1175” security rating.
The LPS 1175 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 a 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.
