Cold Rolling

Cold rolled strip is used in a variety of applications. It meets high demands on forming behaviour, dimensional tolerances and surface finish, which offers our customers decisive advantages! HFP cold rolled strip is ideally suited for all stamping, bending, drawing and deep drawing purposes. From ball bearing housings to roll cutting and punching strips, hose clamps, headlight reflectors, electrical equipment, office supplies and tubes to safety parts of all kinds, a wide variety of components can be manufactured for various industries. DC 01, DC 03, DC 04 according to DIN EN 10139 / mild steel - St 37/ special grades on request Depending on the customer's requirements, we supply treatment states from LG to C690.

This material group comprises C-steel with low carbon content, good formability and fineblanking quality. Due to case hardening, the components have low-wear surface layers with high hardness and sufficient toughness in the core. They thus combine numerous properties and application possibilities in a wide variety of industries. To increase the wear resistance, you can also carburize or carbonitrate partial areas. C 10 E, C 15 E /➔ according to DIN EN 10132 - 2 Depending on the customer's requirements, we supply treatment states from soft annealed to high cold solidified.

In addition to the product range of classic cold rolling mills, we can also offer our customers electrolytically galvanized strip. The zinc coating offers excellent corrosion protection: In cooperation with our customers, we have developed a product that solves the problem of zinc abrasion in the processing of galvanized strips - ZPL (Zinc Plus Paint). An organic coating system is applied immediately after electrolytic galvanizing. This results in a colourless, uniform, highly lubricious layer with a dry film thickness of 0.50 - 3.00 µm, which can of course also be supplied in any desired colour. ZPL offers the following advantages: Further improvement of corrosion protection Excellent sliding properties, preventing zinc abrasion in the tool Reduced tool wear Longer tool life Oil-free processing is made possible Coating and printable layer with "Anti Finger Print" properties

Our tasks also include joint process optimization with our customers in order to enable more efficient production and thus a reduction in set-up and downtimes. Our spooling systems are a good example of this type of cooperation and continuous further development. We connect the strips using state-of-the-art welding technology and rewind them oscillating on a variety of spools Strip widths from 1.5 mm up to 60 mm Extension of the strip length to more than 200,000 meters in one strip depending on the material Individual laying widths from 100 to 400 mm Special decoiling racks with decoiling widths of 800 mm and maximum decoiling weights of 2,500 kg
