Questions & Answers

Have a Question?

Ask a Question
  • Do I really need anchors or bracing? If so, how many do I need? Which style do you recommend?

    Yes, anchors/bracing are important to the long-term stability of the edging.  In almost all cases, 2 per section is recommended. There are 2 choices:  1.  The universal turnbuckle style simply clips to the back of the edging bracket and is extended via a chain diagonally where a peg is pounded into the ground.  2.  The anchor post is screwed to the side of the bracket on the back of the edging and pounded into the ground vertically. The anchor post works well in normal soil conditions.  Concrete should be used around the post.  The universal turnbuckle brace works both in normal and soft ground conditions.  Please note that in soft ground conditions, concrete is recommended around the peg and nails as well. As far as ease of install.  Neither is hard to install, but the Universal turnbuckle style is probably the easier of the 2 methods. Note: When connecting 2 flexible Sections together to form a circle you would not need bracing, anything larger you would.

  • Can the rigidline and flexline be joined together?

    Yes, the rigidline and flexline both have the same connectors, so they can be joined together.  In fact, the 9.5”, 15.75”, and 22” can all be connected together at the top.  This helps in situation where there is a slope, and you need to bury a portion of the edging.

  • What type of saw should I use if I need to cut the edging?

    The manufacturers recommend an angle grinder.  The main point in selecting a saw to cut with is that it uses a metal cutting saw blade and that you are comfortable using it.  If you are not comfortable using a saw, we highly recommend getting a professional’s assistance.

  • When do I need to use a joining sleeve?

    Joining sleeves are used to reconnect edging that has been cut.  If you cut the edging, therefore cutting off the pre-built in connectors, and then need reconnect it to another piece and joining sleeve is used to re- join the pieces.

  • What is included in the price of a single section of edging?

    Included in the price of the edging are 1 – 7 foot section, a joining plate to connect the edging to the next section, and 5 long twisted nails.  Bracing/anchors, premade corners, and joining sleeves are purchased separately.

  • What are the dimensions of the corners?

    Each arm of the corner is 10 inches.  So, 10 inches, then the 90 degree bend and another 10 inches.

  • Hi! I am in the process of re-landscaping. How much of this would I need to order to create a 6' diameter circular garden with a 3' diameter insert . . . and how many braces would I need? Thanks so much!

    Good morning,
    I am so sorry for the delay in response.

    A couple of things:

    The 3' diameter ring wouldn't be possible with this particular edging (due to the flexiblility of the product) as the minimum diameter you would be able to make is 4.5'.  This can be done by connecting 2 sections together.

    For a 6' diameter ring, you would need 2.66 pieces of edging, so a total of 3.  You would have to cut a piece off and then you would need an joining sleeve to reconnect.  If your project allows for a slightly larger circle, it is always recommended...and easier to use the full lengths of the sections and just connect 3 sections together.  3 sections would give you a diameter of 6.76'.

    You wouldn't need bracing.  Bracing is recommended for long runs, but the nature of the circle would support itself.

    So, for your project, with the suggestions, you would need a total of 5 sections. (and 1 joining sleeve if you want to make the cut for the 6' circle)

    There's a great video that shows how to install circles (especially the smaller one) https://www.youtube.com/watch?v=SAF5Ht8Oe5Y

    I hope this helps.  If you have any other questions, please let me know!!


  • Would this be usable in a veggie garden and be food safe or just for plants?

    Good morning,
    I am so sorry for the delay in response.  Yes, the steel edging is pefectly safe for us in vegetable gardens.  It is mostly composed of Neat Iron (Fe) around 98 percent.  The other elements in much smaller increments are:

    So, nothing in there that should be of any harm when growing veggies.

Really Good Product

I'm so glad that I found this product from Henderson Garden Supply. My landscape design called for Corten steel edging, but I had difficulty finding something that would be relatively easy to install. Problem solved! I can't say enough about how easy to install, so sturdy, so easy to work with,... is this product. I really do love it and it looks great.

Fantastic Product

Things that impress me about this product:
a) Looks great. Can't wait to see how it weathers and changes color.
b) Very sturdy. The parts for mounting are very heavy duty, as is the product itself.
c) Very easy to install. It takes a bit of elbow grease to bend it, but even then it's easy to install. The project went much faster than I had expected.

First off, shipping to the west coast took less than a week. I am so glad I had my plan for this diy project traced out and ready to go.
The QR code on the side of the panels was really efficient compared to paper instructions. This was a large project to take on. I had my neighbor on stand by if I needed his assistance after reading some reviews. Luckily, I was able to assemble it all by my self. In less than four hours.
The nails and anchors were very useful. With the Oregon rain. The patina is already starting to come through.
I highly recommend this product! It was much cheaper than concrete, blocks, or boring retaining walls.

I used two of the 7 ft 15 inch pieces to make a 4.5 ft round garden bed. I can't comment on how they weather since I just put it together, but I'm excited to see the rust patina.

These are incredibly heavy duty, well-made, and worth the cost. You have to be fairly handy to make the ring, but follow the directions on the video (you must use a ratchet strap), get a helper, and you should be fine. The result is worth it.

I highly recommend this product - it's unusual that a non-pro would have direct access to this level of quality product. It is expensive, but less costly than it would be to have a landscape company install it.
