Solid guardrails, be they wood or metal, can also be made porous through cuts. This curving stair — easily one of the most elegant on Houzz — is a beautiful design that bridges art nouveau and modern/contemporary design. The flower-like pattern cut in the steel varies from solid to areas with spindly lines, but the overall effect is of something solid and heavy. No doubt this effect is related to the material, the color, and the way the steel plates extend beyond the steps.
