Important: a floor plate, not a hearth

This is a decorative and protective floor plate that sits on top of a compliant hearth. It does not replace the constructional or superimposed hearth that Building Regulations require for a stove. Check your stove manufacturer’s instructions and Approved Document J, or ask a HETAS-registered installer. Mild steel plates arrive unpainted with a mill finish. Many customers finish them with stove paint or black polish, and you can wax or seal stainless to taste.

Choose your material

  • Mild steel: the economical choice. Paint, prime or galvanise it for outdoor use.
  • 304 stainless: the everyday stainless grade for indoor and sheltered outdoor use.
  • 316 stainless: best near the coast, pools, salt or chemicals. 304 vs 316 explained.

Questions

Which thickness should I choose?
3 mm is the usual choice under a stove. 4 mm and 5 mm feel more solid and are less likely to dish, but they weigh more.

How heavy is a 900 × 600 plate?
About 12.7 kg in 3 mm mild steel and 21 kg in 5 mm.

Will it come painted?
No. Mild steel is supplied unpainted (mill finish), so you can finish it how you like.

Are these laser cut?
No. They are plasma cut and deburred, so edges show a plasma-cut finish and are not held to laser-cut tolerances. For tight-tolerance parts, send us a drawing.
