A stainless steel flue box is a heat-resistant enclosure component designed to collect, contain, and direct exhaust gases, smoke, heat, and combustion by-products from fireplaces, grills, ovens, ventilation systems, and industrial heating equipment.

A stainless steel flue box is:

  • A stainless steel exhaust enclosure designed to capture and guide heat, smoke, and gases
  • A heat-resistant transition component connecting cooking or heating equipment to ventilation systems
  • A durable and corrosion-resistant solution for high-temperature exhaust applications

It is used to:

  • Collect and direct smoke, fumes, and combustion gases
  • Improve exhaust airflow and ventilation efficiency
  • Protect surrounding structures from excessive heat exposure
  • Provide a safe and reliable connection between equipment and flue systems
