PHR Security Grilles & Gates London
Specialist manufacturers, suppliers & installers since 1974



By specialising in the manufacture and installation of security gates and security grilles, we offer a diverse approach to delivering requirements that balance well across constraints in time and cost, whilst providing a high quality solution.


Our manufacturers and installers also survey and measure, and they oversee the job from design to installation. They are your single point of call.

We have good control over our contingencies and our timing primarily depends upon our own stock materials. We don't use 3rd party manufacturers to supply your grilles and gates.

Friendly Prices

We purchase raw materials direct from suppliers to manufacure our own security grilles and collapsible gates. With our wealth of experience in manufacturing we understand our materials and the best way to source them, and this keeps our prices low!

Collapsible Gates

Habitable and sustainable, collapsible gates are considered the most versatile retractable security grille option to choose for windows and doors. When in the unsecured position the lattice retracts within the grilles structure to minimise its appearance. This makes collapsible gates a viable option for fire and safety compliance, and often a preferred grille option for aesthetical reasons.

For a range of permanently fixed grille solutions which could offer a better range of ideas to suit your security needs, check window bar grilles or window mesh grilles.

  • Thickest Materials Available
  • Individually Made, No Mass Stock Assembly Sizes
  • Push to Lock Mechanism
  • Fully Adaptable to Best Suit Windows & Doors
  • Minimal Bunching Space When Gates Are Open. Check Here!

Our collapsible gates are operated from a simple push-to-lock mechanism and are not built into the gate. If necessary, it is possible to change the locks for alternative types after they're installed.

We manufacture each individual gate by hand and have the capability to make specific adjustments to suit a range of requirements. Some of our customers like to prioritise and maintain detailed building features which they value more than grilles, and we like to understand this.

To protect windows from burglary and break-ins, installing window bar grilles are often considered the ultimate solution. A bar grille is a type of security grille that consists of steel bars welded within a frame and fixed to a window to restrict unwanted access. There is no strict rule as to how they're made, but there are some common styles which are often seen within London and other towns and cities. You can find more information on that here.

Unlike retractable grille types, Bar Grilles are often the static grille option which is why they are commonly specified and used for strong, high security needs. It is possible to add removable/hinged features for safety purposes, but before considering this be sure to look into collapsible gates which are considered the most suitable grille for opening and closing. They can be made in various ways to suit a range of openings and installed both internally and externally.

A security grille with minimal gaps as it's main feature, mesh grilles are well applied to offer a restrictive form of access. Whilst offering a reasonable level of overall security, mesh grilles help prevent breaking glass and restrict objects or hands to pass through it's barrier.

  • Diamond Expanded Mesh in Different Sizes
  • Square or Rectangular Weld Mesh in Different Sizes
  • Security Mesh Caged Grilles
  • Manufactured Specifically to Suit Each Window/Door
  • Often The Chepaest Security Grille Choice

We can offer a range of mesh to suit a specification. As standard, we offer expanded diamond mesh and square weld mesh types.

Mesh is often used as a fixed grille solution, but it is of course possible to add hinges or removable framed sections.

As similarly described for security window bars, bar grille doors offer an additional barrier specifically for doors and other walk-through openings. To increase security to an existing door a bar grille door can offer some additional security features and provide a good extra level of protection. As an individual door it can offer a barrier to passages whilst maintaining visiblity and air flow.

  • Individually Made, Not From Stock Sizes
  • Insurance Approved BS3621 Lock
  • Manufactured to Match Existing/Additional Doors
  • Steel Artwork or Steel Sheeted Options Available
  • Great Additional Barrier to Doors

We manufacture and install our bar doors to include a british standard (BS3621) lock which is typically approved by insurance companies. Our standard locks can be changed at a later date and are reasonably avaiable for public purchase.
