Abstract
Decking with a panel of uniform thickness sheet metal has a repeating pattern of top flanges and bottom flanges connected by webs therebetween. At least one flange is made up of a plurality of folded-layer segments adjacent to each other in a stacked position to increase the thickness of the flange. Additionally a structural member extending along a longitudinal axis has a uniform thickness plate folded back onto itself about the longitudinal axis or an axis parallel to the longitudinal axis to increase the thickness and provide greater resistance to buckling in response to compressive forces. Such structural members not only provides certain structural advantages but also may provide an aesthetically pleasing appearance.

Decking comprising a panel of uniform thickness sheet metal having a repeating pattern of top flanges and bottom flanges connected by webs therebetween, wherein at least one flange is comprised of a plurality of folded-layer segments adjacent to each other in a stacked position to increase the thickness of the flange.
Decking comprising a panel of uniform thickness sheet metal having a repeating pattern of top flanges and bottom flanges connected by webs therebetween, wherein at least one flange is comprised of a folded-layer segments adjacent to each to increase the thickness of the flange, wherein the panel further comprises:
- a) a series of adjacent top flanges and a series of adjacent bottom flanges;
- b) wherein each top flange has a first and second end and each bottom flange has a first and second end;
- c) wherein the first end of one bottom flange is connected to the second end of one top flange and the second end of the bottom flange is connected to the first end of a different top flange;
- and
- d) wherein at least one flange is folded to make up multiple folds defining two separate spaced-apart switch-back configurations with a gap therebetween providing a portion of the flange with a three deep layer.
A structural member extending along a longitudinal axis comprising a uniform thickness plate folded back onto itself about the longitudinal axis or an axis parallel to the longitudinal axis to provide greater resistance to buckling in response to compressive forces.
A method for forming decking comprising the steps of, beginning with a uniform thickness structural member, bending the member to provide a repeating pattern of top flanges and bottom flanges connected by webs therebetween, wherein at least one flange is comprised of a plurality of folded-layer segments adjacent to each other in a stacked position to increase the thickness of the flange.
A method for forming piling comprising the step of beginning with a uniform thickness structural member extending along a longitudinal axis, bending the member onto itself about the longitudinal axis or an axis parallel to the longitudinal axis to provide greater resistance to buckling in response to compressive forces.
Decking comprising a panel of uniform thickness sheet metal having a repeating pattern of top flanges and bottom flanges connected by webs therebetween, wherein at least one flange is comprised of a plurality of folded-layer segments adjacent to each other in a stacked position to increase the thickness of the flange and wherein the sheet metal is a single folded sheet with minimum discontinuities thereby providing an aesthetically pleasing appearance.
