Grating

A grating assembly for a support structure comprising:

• a grating comprising a piece of metal including a perimeter edge and a surface bound by the perimeter edge, the piece of metal defining an array of uniform surface modifications on the surface of the piece of metal;
• and
• a structure attached to the grating by at least one fastener such that the structure engages the surface of the piece of metal, the at least one fastener extending through an area of the surface that is not occupied by the array of uniform surface modifications, the area being surrounded on all sides by the array of uniform surface modifications, wherein the perimeter edge is defined by first sides and second sides each extending between the first sides, the structure comprising a grab iron attached to the grating, the grab iron comprising a bar for grasping the grab iron and a pair of openings receiving fasteners to attach the grab iron to the grating, the fasteners extending through areas of the surface that are not occupied by the array of uniform surface modifications.

A method of forming a grating for a support structure comprising:

• placing a piece of metal into a device;
• creating an array of uniform surface modifications in the piece of metal using the device such that the uniform surface modifications are arranged in a repeated pattern across a surface of the piece of metal, the repeated pattern of uniform surface modifications being consistent across the surface but for only a pair of spaced apart areas of inconsistency where the uniform surface modifications are not formed in the surface, each area of inconsistency being surrounded on all sides by the array of uniform surface modifications, the pair of areas of inconsistency providing an indication of where to attach a structure to the grating.
