Marine Grade Polished Stainless Steel. This elegant Balustrade was created to enhance this multi storey home without obscuring panoramic ocean views. Stainless Steel is all Polished 316 (marine) grade. We used 50.8mm tube for the toprail and 20mm tube for infill bars with a shaped, flatbar intermediate brace in curved areas to maintain spacings without sacrificing view. Posts were double fin style for this project made from mild steel hot dipped galvanised after fabrication and powdercoated to match existing colour schemes with outstanding results.
