Experience

LSAW Pipe Production

Cimolai acquista le lamiere per la produzione di tubi esclusivamente da primarie acciaierie qualificate. Nella selezione dei fornitori vengono valutati diversi parametri, tra cui le normative applicabili, la classe del materiale, eventuali requisiti aggiuntivi, nonché la larghezza, lo spessore, il peso delle lamiere e i tempi di consegna richiesti.
È inoltre possibile eseguire commesse utilizzando lamiere fornite dal cliente in conto fornitura.
