Robust

Robust

Alumax-Robust family of internal floating roofs were developed in response to the market demand for a high quality, high strength aluminum pontoon roof that can readily accommodate a mechanical shoe seal and not be subject to the failure modes that plague conventional lightweight designs. All Robust roofs meet or exceed the requirements of API 650 Appendix H.

Robust eliminates the typically weak and failure prone problems found in standard aluminum roofs. Broken leg gussets, legs ripped through deck sheeting, cracks in the welds of pontoon end caps, hydrocarbon vapor leakage through deck bolting along with many other common AIFR problems are a thing of the past.

The Robust unique structural arrangement is based on an extremely efficient strength to weight ratio deck support system. This high strength deck system allows for complete support of the roof independent of the pontoons.

The unique rim channel design incorporating the same superior strength given to the deck structure allows for the mounting of primary shoe seals and secondary seals without any modifications to the standard roof.

Design Features

  • ATECO IFR’s are designed to meet or exceed the requirements of API-650 Appendix-H.
  • Heavy Duty Design – 500 lbs/ft2 Loading Capacity.
  • High Section Modulus Main “H” Beam and Sheeting Clamp Channel.
  • 10″ Seamless 2,5 mm Pontoons, High Strength , High Quality Aluminium Alloy.
  • %100 Pre-Fabricated ( All components Pre-Punched in the workshop ).
  • Bended Peripherical Rim Channel ( Special Design ).
  • Gas-Tight Bolting Channel ( Special Clamping System ).
  • All Stainless Steel Fasteners.
  • 1 1⁄2″ – 3 mm High Strenght Support Legs At The Rim and Centre Deck.
  • All Centre Deck Legs Are Connected To The IFR Frame, Not to Pontoon Ends. This Eliminates The Possibility Of Pontoon End Cracking Due To IFR Flexing In Service. 
  • Unique, Easy and Speedly Installation.
  • Screwed Test Port. ( Pop-Rivet Test Port Not Accepted ).
  • Cable Suspended Design Option. 
  • Hybrid IFR’s with all-stainless steel wetted parts available.
