New and innovative developments for design and installation of deep corrugated buried flexible steel structures

Extreme long spans and high earth covers on buried flexible structures have long presented challenges to the design engineer. For deep corrugated products the technical challenges are primarily associated with joint capacities and bending moments. Atlantic Industries Limited has two new products: Ultra-Cor and four sided flanges for Ultra-Cor and Super-Cor plate. Ultra-Cor plate has a corrugation profile that is deeper than Super-Cor, resulting in a large flexural capacity. In many applications, Ultra-Cor will permit bigger spans, heavier live loads, and lower rise structures. Four sided flange connections for Ultra-Cor and Super-Cor plate permit one sided assembly, simplify the assembly process, increase connection capacity and provide a means to more easily construct water-tight buried structures. These new products and features enable buried structure solutions for a wider range of applications.
