Rail sections specified to be installed on curves having a radius of 5 feet (1.5 m) to 150 feet (45.7 m) can be curved in our fabrication facilities prior to delivery. Rail can be curved either convex or concave as required. Terms convex or concave refer to the direction curved, outward or inward, relative to the traffic face of the rail.
 
Note: Follow the steps for each piece of rail section in the curved run. The arc may not be consistent and each consecutive piece of rail may differ in radius from the previous one. Please consult with an individual approved by the governmental authority specifying and supervising the installation of the guardrail.
