Glass and metals

Processing companies in this demanding sector are often faced with economic and environmental challenges and opportunities such as:

  • Innovating new or modified products to meet market demands.
  • Minimising operating costs such as energy and recycling to recover valuable metals
  • Pressure to minimise internal engineering costs.
  • Improved equipment reliability.


RB Group is well versed both technically and commercially in this sector and is often chosen as a natural engineering consultancy partner.


Long-term collaboration with many clients in the design, construction, refurbishment and project handling of:

  • Furnaces for zinc galvanising.
  • Rockwool manufacturing line.
  • 3 glass furnaces and 2 glass coating plants in Chile and the UK.
  • Lead battery recycling, lead refining and silver recovery plant.
  • Catalytic converter manufacturing for car exhausts.
  • Turnkey facility to ‘wash’ gemstones and increase their value.



RB Group provides support through part or all of the entire project lifecycle, thereby avoiding major pitfalls which can result in a project overrunning, being delayed, or under-performing. Examples include:

  • GAP analysis leading to improved productivity.
  • Preparing cases for capital justifications and sanctioning.
  • Horizon scanning to develop innovative solutions to enhance plant operating performance and reduce operating costs.
  • Achieving planning permissions.
  • Obtaining approval from regulatory authorities such as the HSE, EA.
  • CDM.
  • Procurement.
  • Site services, infrastructure, and supervision of sub-contractors ensuring adhesion to programme.


Several RB Group engineers come directly from a manufacturing environment having designed and built furnaces, mills and coating lines all over the world and at all scales, in the following areas:

  • Civil, structural, architectural, process, mechanical, electrical, control, automation, steel and lead processing, and recycling.
  • Separation and treatment of by-products such as metal slag, for metal recovery and conversion into construction materials.
  • Blast and induction furnaces, oxygen lances.
  • Hot-duct designs including both water and evaporatively-cooled.
  • Heat treating.
  • Plate glass coating.
  • Iron smelting.
  • Steel rolling and coating.
  • Rockwool fibre and glass fibre insulation.
  • Precious metals processing including silver extraction and platinum.
  • Gemstone washing with molten salts.
