Security, Vault and Strongroom Doors

There is a large selection of security doors of various types and levels of burgular resistance, these include:

  • External door sets to meet LPS 1175, which has Burglary Resistance Grades 1 - 5,
  • Vault and strongroom doors, which provide the highest grade of protection.

JP Lock and Safe can supply, install, maintain, repair and upgrade any type of security, vault or strongroom doors.  We have agreements with several UK manufacturers and can customise door sets to meet a wide variety of needs.

In simple terms, the higher the security rating, the longer it will take to defeat the door and the greater the range of tools that will be needed.

Wooden door sets from 20 years ago are no match for modern criminals. The wooden substrate will deteriorate over time unless regularly maintained. Door furniture such as hinges or locks may well be worn causing doors to operate incorrectly, leading to greater wear and creating vulnerabilities for criminals to exploit.  It would be irresponsible of us to publish a long list of the ways that wooden doors could be defeated, but rest assured its a pretty long list.

For commercial properties we would recommend metal security doors. These will meet the Insurance requirements and provide reliable operation for years to come. We have been installing metal doors for over a decade and although a few have (rather foolishly) tried, we are proud that nobody has managed to get through one of our security doors yet.

We will be pleased to provide you with a quotation for the supply and installation a Doorsets to meet your specific requirements, including

  • Security level, bespoke dimensions, overall colour.
  • Various frame types and sizes to suit inward or outward opening.
  • Lock mechanism(s), including keyed, or emergency exit variants, outside access (if required).
  • Door stays, restrictors, dampers or closers.
  • Vision Panels (0-2), Letter and Kick plates.
  • Alarm contacts and/or interface for door control systems.

Example of a Security Door for a Commercial Kitchen

An old wooden inward opening door in a commercial kitchen was subjected to an attack using a gas cylinder as a crude battering ram.

We initially secured the door and specified a replacement to meet current Insurance and Fire Regulations.

We changed the inward opening wooden door to an outward opening steel door:

  • Changing the direction of opening increased the kitchen working space for the customer,
  • Opening in the 'Direction of Travel ' also improved compliance with Fire Regulations,
  • A heavy duty Crash Bar mechanism was added to comply with both the Fire Regulations and Insurance Conditions,
  • An outward opening door can't be kicked in or battered down,
  • The door was fitted without any external features, so itcan't 'jemmied' or pulled open from outside,
  • We added a stay open device, so that the door can easily be kept open when required,
  • A white powder coated finish was chosen to allow allow easy cleaning.

Example of a High Security Stockroom Door

We assessed the security features of a solid metal security door between a stockroom and the outside street.  The door was manufactured by a local engineering company long before the LPCB had developed their door testing standards.  Our assessment report was used by the customer to sucessfully demonstrate to their insurers that although the door was old it was more than adequate for its intended purpose.

However the key operated lock on the door was unreliable and due to its obsolete design a like for like replacement was not possible. Additionally the Fire Officer wanted keyless exit because of the lenght of the alternative exit route.

We were able to specify and fit a heavy duty lock that exceeded the insurers requirements and also allowed keyless exit to comply with the Fire Officers requirements.  Additionally we incorporated a signal into the Intruder Alarm system that positively confirms the door is locked before the alarm system is set. This gave additional reassurance for the customer and the Insurance company since the locks status is permanently monitored and logged in the intruder alarm aswell.

Loss Prevention Standard 1175 - Security Ratings

All LPS1175 doors are designed to provide resistance to physical attack by individuals over specified periods of time and usingvarious toolkits.  Higher grades of resistance are achieved where it takes substantially longer (or a greater number of tools) to defeat the door.

The Security Ratingsare described below

SR1: Opportunist attack of up to 10 minutes by bodily force using minimal tools (e.g. screwdriver, knife, pliers, etc)

SR2: More determined opportunist attack of up to 15 minutes with tools of a higher mechanical advantage (e.g. SR1 tools plus bolt cutters, claw hammer, drill, etc).

SR3: Deliberate forced entry of protected premises lasting up to 20 minutes using bodily force and a selection of attack options (e.g. SR2 tools plus short axe, chisels, crowbar, gas torch, etc).

SR4: Experienced attempts at forced entry for up to 30 minutes with higher tool levels (e.g. SR3 tools plus felling axe, sledgehammer, steel wedges, disc grinder, jigsaw, etc).

SR5: Serious attempts at forced entry for up to 30 minutes with high performance battery power tools (e.g. SR4 tools plus circular saw and 750W reciprocating saw with specialist blades). SR5 provides a significant step up in protection level from SR4 – using state of the art cutting tools. However these tools are readily available to anybody with serious intent.
