Key features
  • Weathering steel forms a dense patina which protects it from oxygen, slowing corrosion for a useful life of 50 to 120 years.
  • Weathering steel doesn’t need any further protection eliminating, in most cases, the need for galvanising, painting and ongoing maintenance.
  • The natural and evolving patina of weathering grade Celsius® blends in perfectly with the natural environment.
  • All Celsius® hollow sections are true hot finished, so free from internal stresses and with tight corner radii to maximise weldable-surface and enhance aesthetic appeal, whilst avoiding the risk of brittle fracture which occurs in some cold formed products.
  • The corner radius on squares and rectangles is 2T max. This exceeds the requirements of EN 10210:2006.
  • Weathering grade Celsius® has a low CEV of 0.44 max. This guarantees excellent weldability.
  • Suitable for galvanising (where necessary) and for low temperature applications (40J @ -20°C). 
  • Batch-tested and fully traceable, supplied with a full 3.1 test certificate.
  • All Celsius® sections are CE marked and fully compliant with the Construction Products Regulation.
  • Available in a wide range of circular, square and rectangular hollow sections with a wall thickness up to 16mm.
  • Full technical support in material selection and application available.
