Complete Your Project
Creating a complete landscape design? Customers who purchase this edging often also use:
-
4" Heavy Duty Edging - For lower-profile raised beds in the same weathering steel finish
-
3" Zero Flex Edging - For pathways and borders around your raised beds
-
Multiple Sections - Most raised bed projects require 4-8 sections to create a complete bed
💡 Pro Tip: The 6" height is perfect for raised vegetable gardens and deep-rooted plants, providing ample soil depth while the 7mm thickness ensures the edging won't bow under soil pressure. CorTen weathering steel develops a beautiful rust patina over 3-6 months, which actually protects the steel and ensures decades of durability. Calculate your bed size and order enough sections to complete your project - most 4'x8' raised beds require 6-7 sections.

About CorTen Weathering Steel
CorTen is a high-grade weathering steel alloy developed to eliminate the need for painting. When exposed to the elements, it forms a stable, rust-like appearance that protects the steel from further corrosion. The edging arrives in its natural black/gray state and will develop the characteristic rust patina over time, with the timeline depending on your local weather conditions.
