<p>A metal swimming pool wall is designed to extend around a pool. Metal members extend outwardly from the pool and are apertured adjacent their outer ends to be bolted or rivetted to a metal strip having corresponding apertures. By determining, at various locations about the pool, that the spacing between adjacent bolted or rivetted holes in the strip shall be longer, equal or shorter than the spacing of the wall metal member, the pool may be shaped to be concave inward, straight or convex respectively.</p> |
