The ball-top arched metal garden railing panel is heavy-duty and has high-quality fencing. Fits a total POST-TO POST GAP of 1830mm, we already account for the hinge gaps required. The physical width is 1810mm. The height to the top of the ball finial is 455mm rising to 625mm in the centre. The side frame height is 362mm. Electro-galvanized for added rust resistance and powder-coated black, the finish must be inspected, and any chips touched up. The galvanizing is not a 100% rustproof guarantee. Like any outdoor metal product, it may need to be painted every couple of years to ensure a long life. Comes with angle brackets and bolts, but no screws. Nuts and bolts must be painted after fitting to prevent the onset of rust. Made from solid metal frames 25mm x 10mm and Infill bars 12mm in diameter.
