I have to erect some shelves: 22 inches wide, supported at the ends by
heavy-duty bookcase-type uprights and brackets. This is to hold fairly

Given an equal thickness (18mm? 20mm? More?) and a choice between MDF,
plywood, veneered chipboard, solid timber or something else, would any
particular material be preferable? 22 inches isn't much of a span, is it?
And appearance isn't really a factor.

Many thanks.

All of those & more would work. They all have their pros & cons.
