No, the cost of guard rails is dependent on the shape, size, and length of the rails that are needed. For example, curved guard rails can cost you around $260 for a 4.0 metre piece that has galvanised coating and $550 for the same length that is finished in a safety yellow powder coat.
Other types of guardrail, for example, circular guard rail is more expensive and can cost around $1,350 for a 500 mm circle. Straight lengths are generally cheaper than special-shaped pieces and can roughly cost $60 per metre if galvanised and $120 per metre if powder-coated to safety yellow.
