If you've ever seen a metal raised garden bed bow outward after a winter freeze, you've witnessed what happens when thin steel meets soil pressure and freeze-thaw cycles. The soil expands as it freezes, pushing outward against the panels — and thin steel gives way.
The fix is simple: thicker steel. Tefora uses 1.0mm total panel thickness (0.6mm DC51D steel core + extra-thick coating) so the panels hold their shape through Canadian winters without bulging, warping, or needing replacement.
1.0mm steel. No bulging. No warping. Built to last decades.
Tefora's extra-thick panels hold their shape through freeze-thaw cycles — so you're not replacing your bed every few years.
