This Ball Top Metal Garden Railing panel features a frame shoulder height of 360mm and a height of 455mm to the top of the ball finials. It is designed to fit a post-to-post gap of 1830mm (6ft). The panel is electro-galvanized for enhanced rust resistance and powder-coated in black. While galvanizing offers added protection, it is not a complete rust-proof guarantee. Like all metal products, this railing may require inspection and touch-up painting every few years to ensure longevity. It includes angle brackets and bolts, but no screws. The construction features thick and sturdy 25mmx10mm frames with 12mm infill bars. Optional bolt-down metal posts are available separately; search for BP50X500 POST for flat-top posts or BP50X500B POST for ball-top blank metal posts.
