About Kallas Edelstahl
KALLAS EDELSTAHL GmbH is a family business founded in 2001 in Krefeld and has established itself as a recognized stockist of stainless steel semi-finished products, in particular welded stainless steel tubes, in Germany and beyond. The product range includes line tubes to EN ISO 10217-7 TC1/TC2, heat exchanger tubes to AD2000/W2, structural tubes to EN 10296-2 and beverage line tubes to DIN 10357, as well as round, angle and flat steel and bright steel. In addition to the warehousing business, the company supplies its customers with new production and one-off custom items for special dimensions via European partner mills. In-house processing is carried out on site: on three sawing machines, fixed lengths from 100 mm to 6,000 mm are cut at outside diameters from 8 mm to 323.9 mm, complemented by an in-house grinding service, mirror polishing, foil wrapping, punching, restamping and bending. The focus is heat exchanger construction; further customers come from the beverage and food industry as well as plant engineering.
