internal floating roof
ATECO’s ALUMAX-ROBUST ™ Full Contact Floating Roof™ is the most efficient aluminum floating roof available.

• Eliminate vapor space below floating roof.
• Fully welded, pressure tested panels ensure extended maintenance free life and maximize structural strength.
• Average diameter ALUMAX-ROBUST ™ IFR provides 350% excess buoyancy.
• Metallic skins are 2.5 times the API minimum thickness.
• Eliminate product compatibility issues with the installation of an ATECO shoe seal (standard equipment) on the ALUMAX-ROBUST ™ internal floating roof.
• Decrease vapor loss even further by using our cable suspension system.
• Patented Double Clamped joint provides maximum strength and vapor retention. Independent laboratory testing has proven it to be 16 times more efficient than the U.S. EPA default factor.

Our patented, welded module Aluminum ALUMAX-ROBUST Full Contact IFR is designed for owners who prefer the benefits of the full contact aluminum floating roof concept.

ATECO’s welded module design eliminates costly failures and product compatibility concerns associated with an exposed adhesive design. Factory-installed test ports allow future field-testing of each module so that the tank can be certified gas free without concern that dangerous vapors or product may be trapped inside the module.

ATECO Aluminum ALUMAX-ROBUST Full Contact IFRs have been designed around strength and safety, Eliminating concerns of leaking modules and product entrapment associated with other designs.

• No exposed failure prone adhesives
• Module skins are more than 2-1/2 times the API required minimum thickness to reduce corrosion effects and increase strength
• Each module is tested and certified leak free prior to shipment
• ATECO’s standard Aluminum ALUMAX-ROBUST Full Contact IFRs have enough strength and buoyancy to be fitted with single or double shoe seals
• Our standard ALUMAX-ROBUST IFR can support 750 pounds on the outer edge while floating with buoyancy to spare
