Which wood would you recommend for worktop? 
I'm looking for generally most strong/heavy one.
It will be covered with stainless steel sheet on top, but I don't want to put soft wood below steel sheet.
Beauty of wood or its colour are not very important.
Snap On is making their ones from Maple so should be good choice, but is there better one?
I find offers for following ready made ones sold per meter:
OAK 40mm STAVE 40mm
OAK SMALL STAVE - 40mm
PRIME BEECH - 40mm
RUSTIC BEECH - 40mm
EUROPEAN WALNUT - 40mm
WALNUT SMALL STAVE 40mm
IROKO 40mm STAVES 40mm
MAPLE 40mm STAVES - 40mm
And two on expensive side:
FULL STAVE OAK - 38mm
FULL STAVE AMERICAN WALNUT - 38mm
