The substructure construction is stainless steel and is built in sections which are usually the same width as the lanes. Each section is supported at the front and rear: the front legs are bolted onto a special anchoring plate inserted on the overflow gutter and the rear legs sit on the pool deck itself. A strong ABS grid covers the structure, producing a seamless and wall and top surface. The corners are also in ABS and can be supplied in suitable contrasting colors.
