Grates

A grate for drainage of liquid from a surface, the grate comprising:

• a plurality of elongate grate pieces, each grate piece having a solid body with a first end and a second end, each grate piece having at least the first end angled with respect to the body, wherein an edge of the first end of a grate piece is welded to and abuts an adjacent grate piece, and an edge of the second end of the grate piece is welded to and abuts another adjacent grate piece so as to form the grate, and wherein the edge of the first end and the edge of the second end are parallel to each other and to the solid body, wherein a second plurality of the grate pieces, each having the extremities of the first and second ends cut-off at an inclined angle, are welded together to form a section of the grate with vertical curvature, and
• a gap is formed between each of the respective bodies of the grate pieces to permit the drainage of liquid between the grate pieces.

A grate comprising:

• an assembly of elongate grate pieces, wherein each grate piece includes a solid planar body with a first planar end and a second planar end and the first planar end is angled with respect to the solid planar body, and the first planer end has an edge parallel to the planar body and the second planar end has an edge parallel to the solid body;
• a plurality of the elongated pieces each have an edge of the first planar end abutting and welded to an adjacent one of the grate pieces, and an edge of the second planar end abutting and welded to the second planar end of another adjacent one of the grate pieces, wherein the length of the first end is longer than the length of the second end, and
• a gap between each of the solid planar bodies of the adjacent grate pieces.

• a plurality of elongate grate pieces, each grate piece having a solid body with a first end and a second end, each grate piece having at least the first end angled with respect to the body, wherein the first end and the second end of the body of the grate piece each take the form of a leg, the first leg being longer than the second leg, and wherein an edge of the first end of a grate piece is welded to and abuts an adjacent grate piece, and an edge of the second end of the grate piece is welded to and abuts another adjacent grate piece so as to form the grate, and wherein the edge of the first end and the edge of the second end are parallel to each other and to the solid body, and
• a gap is formed between each of the respective bodies of the grate pieces to permit the drainage of liquid between the grate pieces.
