Witgert is also the sole producer and supplier of vacuum-extruded sheets, in the standard forms of type No. 2 sg 40, leather-coloured, and 11 sg 40, white, both with 40 % chamotte/grog 0-2 mm. If required, all other ceramic bodies can also, of course, be produced in sheets-form.

The standard format has a thickness of 18 mm, a width of 50 cm and a length of 75 cm. Naturally other formats can be produced, according to customer requirements. These sheets are suitable for the most varied processing techniques and do not require the additional processing-overhead of a sheets-roller or other block-building methods. Ready-processed sheets are delivered loosely palletted.
