What a utility model records
A utility-model patent registers a specific design. The certificates carry no test data and no performance figures, so nothing is claimed here about how the patented designs perform. The certificate states a ten-year term counted from the filing date.

Both patents cover refractory brick designs. The development route for a non-standard shape or a modified formulation is described on the custom refractory development page, which sets out what the company does and does not take responsibility for.
Published technical tables cover every catalogue product. A data sheet for a specific grade, quantity or service condition is issued by the technical team on request.
