Chamber and Screen

Project Scope
For a new chamber and screen Steelway Brickhouse had to meet with strict operator requirements and enable the easy operation and removal of the screen when the need arose.
Access Cover


  • Manufacture and supply an access cover 4300 x 2900mm
  • Opening of 3000 x 1000mm
  • Removable covers to comply with manual handling guidelines
  • Torsion spring assisted for one person operation
  • The access covers also needed to be locked
  • A galvanised coating in line with UK corrosion values

Access Cover Solution

To meet with these requirements a hybrid design was created based around the Defender. The sales and technical team worked extremely closely with both the designer and contractor, to design and build an access cover with the following specification:


  • Fabricated mild steel multiple access cover and frame
  • 16 cover sections with 4 hinged access covers & 12 lift out
  • Hinged access covers with torsion spring assistance
  • Lift out access covers to include provision for M16 eye bolt lifting
  • Single Sealed
  • Loading capability in line with FACTA classification AA
  • Unique keyless locking system
  • Recessed locking boxes for utility padlocks
  • Galvanised to BS EN ISO1461

Design Collaboration

As part of the collaboration process, a meeting on site was undertaken to survey the area and understand the requirements. This was undertaken not only from a fabrication point of view, but to offer the best solution around health & safety requirements, operator preferences, and to ensure that delivery, offload and installation could be undertaken easily and effectively.

With the site survey information to hand and backed with the understanding of the project, any further design requirements or alterations were accounted for with ease. The access cover requirements changed a number of times before the final design and the technical department worked closely with the designer to accommodate the changes.

Once the design of the screen and chamber were finalised, 3D modeling technology was used for a visual representation of the product. This allowed for design validation and also an error free fabrication, especially important when using lazer cutting technology.

To make sure the team was happy and the contractor knew exactly what to expect upon delivery, the drawing was submitted for final approval, prior to commencement of manufacture. The unit was fabricated and delivered to site within 4 weeks.

The contractor was prepared for the installation with the cross sectional and rebate information given and had no problem installing the unit.

A final visit to site was undertaken to examine and check the units were operating correctly and ensure all parties were happy with the product supplied and the service given.
