Most of the Roof tile manufacturers purchased by Braas (now Lafarge Braas) were put to sleep almost at once.

A-Roof, Hultapannan, Diamantpannan, Bockarapannan, SE-Pannan,
Köping, Stora Tuna, Brunflopannan, Icopalfabriken, Störenfabriken,
Loyapannan, Vaverspannan.

Others were run for some time and later laid down.

It is interesting in this connection to note that not long ago Lafarge was forced to breake up and sell some of its producing units in the US due to its power position.
