Corrugated Boxes- Design and Construction  
                    
                    Steel Boxes and Skid Boxes 
                    Triangular Bead top Flange is standard on all Shanafelt corrugated boxes construction. Considering all directional stresses, this type of flange is two  and a half times stronger than conventional double roll flange construction. It  provides the additional strength and rigidity needed at the top of our corrugated  boxes to resist material impact.                     
                    Corrugations of 1/2 in. radius on 3 in. centers  provide the necessary strength and rigidity in the corrugated boxes’ sides. This full radius extends around the  outside corners of the corrugated box without distortion. These features make  Shanafelt corrugated boxes the best  in the industry.  |
