  • Diameters in excess of 25 m/82 ft
  • Custom sizes and shapes available
  • Fabricated elbows
  • Easy to ship, install
  • Accelerated assembly, easier fitting of plates
  • Smaller crews needed, lower installed costs
  • Added safety, structures can be built from one side
  • Facilitates curved structures (horizontal and vertical)
  • Allow for leak-resistant structures
  • Ideal for remote sites
  • Lower cost tank storage option
  • Structures can be dismantled and removed
  • "THE EDGE" is available on our industry proven Super•Cor Structural Steel Plate
