“Will the rust colour leach into my white gravel?”
No, there is no colour run off during the 5 weeks rusting period or after that. White gravel or white pavers will not become stained.
“Will the steel rust away to a pile of flakes?”
Cor-Ten is much more stable than normal steel. The rusting process only takes place on the outside thus protecting the steel on the inside.
“Can I cut the lengths?”
Cor-Ten can be cut with an angle grinder and the cut edges will also develop the rust finish. However, rather than use an angle grinder to cut off any leftover piece we suggest making an angle (which is easy to do over the corner of a table or workbench, etc) and running the extra bit along the fence or wall or whatever it has run up against (this also makes an effective holding frame to keep in mulch and soil, etc). Alternatively it is also easy to overlap the last two sections of EverEdge rather than joining them together on the clip (they will still hold perfectly).
“What happens if something scrapes off the rust finish?”
If the Cor-Ten does receive a scratch so that the inner silver steel is exposed, it will just rust in the same 5 week period and the scratch will be sealed over.
