Steel processing for the construction and precast industry
Nölken Stahlverarbeitung in Bösel/Glaßdorf in the Oldenburger Münsterland manufactures steel built-in components, assembly parts and brick slip support systems made from structural steel, stainless steel and duplex. The product range includes anchor plates, built-in parts, threaded parts, anchor cages, tread protection solutions, edge protection angles as well as loose and fixed flange constructions and console anchors. Production comprises plate shear cutting, plasma cutting, bending, milling and robot-assisted welding, including certified rebar and stud welding. Supply is primarily to the concrete and precast industry as well as to structural, road and bridge construction. On request, components receive corrosion protection through priming, electro-galvanizing, hot-dip galvanizing or coating; black-white connections are feasible. With around 30 employees and over 57 years of experience in steel processing, the company delivers at short notice and reliably from an extensive material warehouse.
