Nothing. The patina forms and then stabilises on its own. Do not paint or seal it, which prevents the weathering that protects the steel underneath.

About this product
Steel that rusts on purpose, and then stops.
High grade corten supplied already weathered, in interlocking 1075 mm sections. The finish designers ask for by name.
Corten is the edging people have usually seen somewhere and then come looking for.
It is weathering steel, A606-4, an alloy formulated so the first layer of rust is dense and tightly bonded. Once it has formed it slows further corrosion instead of accelerating it the way ordinary rust does on mild steel.
That is why it never needs painting or sealing, and why the finish is the product rather than a coating on top of it.
Ours is supplied already weathered, so it looks right the day it goes in rather than after a winter of raw grey steel.
Same 1.5 mm gauge and 1075 mm interlocking sections as the black steel range.
Weathering steel was developed to remove the need for painting structural steel. The alloy is mixed so that the surface oxide is dense and tightly bonded, and once that layer has formed it slows further corrosion rather than flaking off and exposing fresh metal underneath.
In a garden that means edging you install and then genuinely forget about. Nothing to paint, nothing to seal, nothing to service.
The look is why most people buy it. Orange brown against green planting reads as deliberate in a way a black or a bright edge does not, and it gets more convincing as the beds fill in around it.
Two things worth knowing before you order. While the patina is still forming, run off can stain pale paving, render or decking sitting directly below the edging, so think about what is underneath it. And the finish is not uniform: variation between sections is normal and is part of the material rather than a fault.
At 1.5 mm it takes a gentle curve well and a tight one badly. For a circle around a tree, work in a wider radius than you would with the plastic kit.
Still deciding?
Not sure yet? That is fine.
You can change your mind. Under this shop's own returns policy you have 15 days from purchase to send it back in resaleable condition, at your cost and with a $39 handling fee per order. We refund the price you paid, including standard delivery.
If it turns up faulty, damaged or not as described, that is on us. The Consumer Guarantees Act 1993 covers you, we pay the return postage, and you can have a repair, a replacement or your money back. Read the full detail on our refunds and returns page, or ask us anything before you order.
A weathering steel alloy, A606-4, formulated so the surface rust forms a dense tightly bonded layer that slows further corrosion instead of flaking away.
Does it arrive already rusted?
Yes. It is supplied ready weathered, so it looks right the day it goes in rather than after a winter of raw grey steel.
Will it keep rusting away?
No. The patina forms and then stabilises. That is the whole point of the alloy.
Will it stain my paving?
It can, while the patina is still forming. Run off from weathering steel marks pale paving, render and decking, so think about what sits directly below the edging. If that is a concern, the stainless range does not weather at all.
What face height is it?
100 mm.
How long are the sections?
1075 mm, which lay 1000 mm once you allow the 75 mm interlock overlap. So one section is one metre of finished run.
How thick is it?
1.5 mm gauge, the same as the black steel and three times the stainless.
How many spikes come with it?
Seven 100 mm spikes per section.
Can I bend it round a curve?
A gentle one, yes. At 1.5 mm it is the stiffest edging we sell, so a tight circle is easier in the 0.5 mm stainless or the plastic kit.
Should I paint or seal it?
No. Painting or sealing prevents the weathering that protects the steel underneath, which defeats the material.
Is the colour consistent between sections?
No, and that is normal rather than a fault. Variation across a run is part of how the material looks.
How do I install it?
Lay the run, overlap each section into the next by the interlock tab, then drive the spikes through with a rubber mallet. No trench, no concrete.
How does it stop grass runners?
Hammer roughly 30 mm of the edge itself into the ground as well as the spikes. That gives a continuous vertical barrier runners will not cross.
How long will it last?
Weathering steel is specified in architecture precisely because it lasts without maintenance. There is nothing on it to fail and nothing to repaint.
What is the difference between corten and ordinary rusty steel?
Bare cold rolled steel rusts and keeps rusting until it fails. Corten rusts to a protective layer and then effectively stops.
Does it work next to gravel?
Very well. The orange brown against grey gravel and green planting is the combination the material is usually bought for.
How much does a section weigh?
1.6 kg.
Do you cut it to length before shipping?
No. Sections ship whole and you trim if you want a shorter run, so this shop's 15 day change-of-mind policy covers it like anything else here.
How much is delivery?
Delivery anywhere in New Zealand is NZD 25, and it is free once your order reaches NZD 100. There is one delivery service rather than a choice of speeds.
How long does delivery take?
Five to seven days, after a 24 to 48 hour handling time while the order is picked and packed.
Do you deliver across the whole NZ?
Yes, anywhere in New Zealand, from Cape Reinga to Bluff, including Waiheke and Stewart Island.
Is there a minimum order?
No. The per metre and per section ranges are sold by the unit, so you can order one metre or one section if that is all you need.
Can I change my mind after it arrives?
Yes, under this shop's own policy. New Zealand law gives no automatic cooling-off period on an online order, so this is goodwill rather than a statutory right: you have 15 days from purchase, the goods come back in resaleable condition at your cost, and a $39 handling fee applies per order. Email us with your order number first.
What if the item is faulty or not what was described?
That is a separate and stronger right under the Consumer Guarantees Act 1993, and it is not limited to a number of days: it runs for as long as the goods should reasonably have lasted. You can ask for a repair, a replacement or a refund, and we pay the return postage.
Who pays return postage if I simply change my mind?
You do, unless the item is faulty or we sent the wrong thing.
Can I cancel before it ships?
Yes. Contact us with your order number as soon as you can. Most orders are picked within 24 hours, so the sooner the better.
How do I track my order?
You get a confirmation email with a tracking number once the order ships. Items in one order can travel in separate parcels.
What payment methods do you take?
Card payment and PayPal, both through a secure checkout. Card details are handled by the payment provider and never reach this site.
What currency are prices in?
New Zealand dollars, and that is what your card is charged.
Do you sell to trade or in bulk?
Yes. Use the wholesale quote page with the lengths and quantities you need and we will come back with a price.

Nothing in this range is cut to a customer's measurement before it ships: the sections are supplied whole and the customer trims them if a shorter run is needed. New Zealand law gives no change-of-mind cancellation right on an online order, so what covers a change of mind here is this shop's own 15 day returns policy rather than a statute. The Consumer Guarantees Act 1993 covers faulty, unsafe or misdescribed goods separately, and nothing in the returns policy limits it.
