Features and benefits
  • Primary standard EN10255 Grade S195.
  • Hot-finished process route, delivering consistent performance, mechanical properties and improved ductility, compared to competitor cold-formed options that may suffer from internal stresses and increased risk of failure during manipulation.
  • The perfect replacement for BS1387, which is now a withdrawn and unsupported standard.
  • CE marked to CAT 4 (water) for added confidence and application suitability.
  • Controlled, high frequency induction welding process.
  • Rigorous process control produces uniform and exacting tolerances.
  • Produced to a composition designed to eliminate any tendency for strain age embrittlement in service.
  • Fine grain practice for enhanced ductility and weldability.
  • Through product tracking ensures complete traceability.
  • INFIRE™ tube for fire defence applications.
  • A1 fire rated.
  • Readily available in a range of sizes.
  • Our pre-grooved tube offers project savings as well as other installation benefits.
  • Rigid, robust and well proven in use over many years.
  • Sustainable and fully recyclable.
  • Supported by a team of dedicated UK account managers and technical staff.
