Complete Your Project

Creating a complete landscape design? Customers who purchase this edging often also use:

• 3" Zero Flex Edging - For lower-profile applications in the same weathering steel finish
• 6" Heavy Duty Edging - For even taller raised bed applications
• Multiple Sections - Most landscape projects require 5-10 sections depending on the area

💡 Pro Tip: The 7mm thickness makes this edging significantly stronger than standard 1.6mm edging - perfect for commercial applications or areas with heavy foot traffic and equipment. CorTen weathering steel develops a beautiful rust patina over 3-6 months, which actually protects the steel and ensures decades of durability. The 4" height is ideal for raised beds and areas where you need to retain more soil or mulch.

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.
