Corten Retaining Wall Steel Post How To
Corten retaining wall system, corten panels connected to corten steel angle posts set in concrete.
All fixing bolts and screws are hidden
Corten steel angle posts set in concrete pile holes
Our system is ideal for retaining walls 600mm tall up to 1200mm
We are also able to supply taller or shorter retaining walls if required using the same system.
Corten wall braced while concrete sets
All parts in our corten retaining wall system come ready to install, with no special tools required
The steel is either screwed or bolted together
Corten post ready for next panel to be screwed or bolted on
This is an engineer designed system, using the strong steel posts set in concrete pile hole construction method.
This gives you a narrow retaining wall, ideal for where space is limited.
90deg external corner joiner
The modular layout has over 100 different panel sizes to choose from, this enables you to build corten retaining walls that suit almost any location
Change of direction at panel joins
Internal changes of direction at panel joins may not require corner joiners
Corten panel ready for next post to be bolted on
To build the wall you start at one end and continue construction by adding panels and posts
Hole already dug for next post, Add bracing as required, to hold wall in place, lastly pour concrete around support posts.
Secure capping brackets to posts with TEK screws
Capping comes with M10 nuts and bolts to connect to brackets
Retaining wall drainage info
A well built corten retaining wall with proper drainage will easily last 30-50yrs plus, depending on the environment

All parts predrilled for easy assembly
The modular design of Corten panel walls allows for faster installation These panels can be easily put together with minimal required tools and expertise.
Our corten retaining wall system is DIY friendly and all parts come pre drilled ready to install with no special tools required. You should not need to do any cutting or welding of the corten.
The steel is either TEK screwed or bolted together
Corten retaining wall with capping
Corten steel requires no maintenance, as over time it develops a crystalline rust patina that dramatically reduces further corrosion
Posts set in concrete pile holes
Generally the retaining wall pile hole depth is equal to the height of the retaining wall. However in softer soils or walls supporting sloping ground, driveways, or buildings, the post and pile retaining wall method solves this by adjusting the post spacings and pile depths.

Avoid thin corten, which after as little as 10 years may be structurally inadequate
Temporary Braces
Corten support posts, with temporary timber bracing, before concrete is poured into pile holes
Temporary Braces
Corten support posts, with temporary timber bracing, at bottom of post. The corten steel posts have pre-drilled holes, making it easy to add the timber braces.

Longer posts used in softer soils
The modular design of Lego-type corten walls and support posts set in concrete pile holes ,creates a very strong and stable structure that can withstand significant lateral pressure from soil behind the wall.
Corten side returns for steps
Corten walls can be designed to accommodate a variety of curves and angles, making them suitable for use in a wide range of landscaping projects. They can also be built to various heights to meet specific needs.

Corten Steel Care and Maintenance
Corten steel, also known as weathering steel, is a high tensile steel that forms a protective layer of rust or patina when exposed to the elements. This patina shields the steel from further corrosion, giving it a characteristic reddish-brown color.
To form this protective patina, corten steel needs repeated cycles of wetting and drying. If buried or otherwise prevented from experiencing these cycles, corten steel will not develop the patina and will rust at a similar rate to mild steel.
To extend the lifespan of corten steel, ensure all retaining walls have adequate drainage to prevent hydrostatic pressure buildup. Poorly drained retaining walls with saturated soils will shorten the lifespan of unprotected corten steel.
For this reason, it is recommended sealing the insides of planters and the backs of retaining walls made of corten steel with a bitumen sealer.
Thin (1.0mm to 1.5mm thick) unprotected steel when buried has quite a short lifespan
By following these simple care and maintenance tips, you can ensure that your corten steel structures will last for many years to come.

We work with landscapers, architects, engineers, and Diyers to provide corten retaining wall layouts that are easy to assemble, we provide these retaining wall layouts for free. Please contact us via email
Internal and external curved pieces available
Our corten retaining wall system is DIY friendly and all parts come pre drilled ready to install with no special tools required. You should not need to do any cutting or welding of the corten.
Internal and external curved pieces available
These panels come pre-made Just screw them together – it’s like giant Lego for grown-ups!
Premade curved panels allow you to create beautiful, natural-looking curves in your wall. This is great for following the contours of your land or adding a bit of softness to your landscaping.
Rounded corner using quarter panel
Corten walls can have rounded internal or external corners
Then curved panels come in serval radii and heights

Corner joiner angle tolerance
The side folds can be site bent to create a 5deg to 10deg additional change in direction
This allows the installer to cope with angels that are not exactly 45deg or 90deg

The side folds can be site bent to create a 5deg to 10deg additional change in direction
To reduce the change in direction, the top fold can be trimmed by the installer
