RockCurb® Radius Sections can be used when the project incorporates curves. Gentle arches or circles can be accommodated by using a combination of radii and straight sections. A complete selection of internal and external radii are available with either a 12” or 18” height in two profiles. The 18” RockCurb® Radius Section is available in both the angled Battered Profile and the rounded Bullnose Profile. The 12” section is available in the Battered Profile only and a limited number of external radii.
