Manufacturing

Queensbury Shelters manufactures and despatches all of our products from our Portsmouth Factory.

We operate a material requirements planning system (MRP) – a production planning, scheduling and inventory control system used to manage our manufacturing processes.

The typical manufacturing processes involved in building one of our shelters is as follows:

  • Steel Fabrication
  • Aluminium Process
  • Pre-treatment of Aluminium/Sheet Metal Work
  • Pre-treatment of steelwork (done off site)
  • Powder coat of all shelter components
  • Assembly of shelters
  • Despatch of shelters

Our shelters are predominantly manufactured from fabricated steel sections which are cut, formed and welded in our steel bay. Cut and CNC machined aluminium extrusions are used for our glazing systems.

Our in-house pre-treatment process is used for both aluminium and sheet steel material. This three stage cleaning, rinsing and coating process ensures superior performance for powder coated materials. The final coating is a Reactive Coating Technology (RCT) treatment that meets the requirements of BS 6496 and BS 6497 for Zinc and Aluminium.

The hot zinc spray pre-treatment of steelwork is subcontracted to an external provider and meets BS EN 22063:1994 and BS 5493:1977.

All our shelter components are then powder coated to a standard RAL colour of our customer’s choice.  The powder is electrostatically applied to the materials to a thickness of between 75 – 125 microns. Samples are taken of each batch of work to ensure adherence of the finish.  We keep records of these batches to allow future investigation if required.

Assembly and dispatch work is the next stage in the manufacturing process. This includes tapping of the threads in pre-drilled holes, any pre-wiring of posts and gantries and assembly of glazing components, including rubber.  All components are then wrapped ready for despatch and clearly identified.
