Cold-rolled products

HFP not only manufactures classic cold strip but also case hardened, quenched and tempered and spring steels in untempered execution from soft - for the most rigorous forming requirements - to spring tempered.

Surface refinement through electrolytic galvanisation and/or precision cutting on a variety of spooling systems offer our clients an additional attractive service.

For us, performance means offering a wide range of cold-rolled steels with the highest quality at prices in line with market conditions, in which flexibility and high delivery readiness are combined with precise observance of the specified chemical and mechanical values.

Cold rolling requires a perfectly coordinated process, exact configuration and exceedingly precise implementation. Our roll stands – equipped with the latest technology – guarantee production in the highest quality, with consistency.

The heat treatment of the steel is decisive for the material properties of the final products. In contrast to the situation in batch annealing, which tends to be static, our roller hearth annealing furnaces permit continuous homogenisation of the metal structure.

From thickness reduction and heat treatment through to rerolling and subsequent making up, we monitor production with our quality and process management system. In this way, we create the conditions for reproducing all properties and thus lay the basis for effective further processing.

Using the latest production processes, highly motivated employees and reliable suppliers, we are capable of meeting ever-growing market requirements whilst still complying with the environmental criteria.



Cold strip is used in a variety of applications. It satisfies the rigorous requirements imposed on deformation behaviour, dimensional tolerances and surface condition – essential advantages for our clients!

Our cold strip is outstandingly suited for all punching, bending, drawing and deep-drawing applications, e.g. in the automotive industry and for its suppliers, for needle bearing and ball bearing housings, roller cut and punched strips, hose clamps, headlight reflectors, electrical devices, office supplies, profiles, pipes, other steel and sheet steel goods, metal goods, safety parts of all types and much more.

  • DC 01, DC 03, DC 04 acc. to DIN EN 10139 / structural steel – St 37/ special grades on request
  • We deliver treatment conditions from LC to C690, depending on the client's requirement.

This material group includes C-steels with a low carbon content with good formability and fine-cutting quality; it combines numerous properties and thus ensures a truly wide spectrum of possible applications. Partial areas can be carburised or carbonitrided, in order to increase the resistance to wear. Following case hardening, the components possess low-wear surface coatings which are very hard, but there is still sufficient toughness in the core.

  • C 10 E, C 15 E /➔ acc. to DIN EN 10132 - 2
  • We deliver treatment conditions from soft-annealed to highly chilled, depending on the client's requirement.

This group of materials stands for breaking strength, a long service life and resistance to wear. Because of these properties, steel for quenching and tempering is always used where a high strength and yield strength are demanded from highly stressed machine parts, as well as a good level of toughness.

  • C 22 E, C35 E, C 45 E/➔ acc. to DIN EN 10132 - 3
  • We deliver treatment conditions from soft-annealed to highly chilled, depending on the client's requirement.

This material group is characterised by its homogenous structures and optimum surfaces. Spring steel is a byword for resilience. It stands for above-average service life and dimensional stability, and guarantees constant quality for every end product. Spring steel obtains its particular properties from special treatment in the production process, in which case an even distribution of the carbon content is especially important: it undergoes several rolling procedures and repeated heat treatments in numerous work steps – this is how we guarantee optimum quality for your products!

  • C 67 S - C 100 S/➔ acc. to DIN EN 10132 – 4
  • We deliver treatment conditions from soft-annealed to highly chilled, depending on the client's requirement.

Electrolytic galvanisation

Beyond the product range of classic cold rolling mills, we can also offer our clients electrolytically galvanised strips. The zinc coating offers outstanding protection against corrosion; cathodic protection is a specialty in this regard. This process ensures that mechanical damage to the zinc coating or the cut edge of the galvanised strip will not be subject to corrosion. In this case the influence of nature forms a galvanic element. The unrefined zinc acts as a "sacrifice" for the more highly refined steel and protects the non-galvanised point.


In cooperation with our clients, we have developed a product that provides a remedy to the problem of zinc abrasion during the processing of galvanised strips – ZPL (Zink Plus Lack). This involves an organic coating system (the lacquer, or "Lack") being applied directly after the electrolytic galvanisation. The result is a colourless, smooth layer with good slip properties and a dry film thickness of 0.50 – 3.00 µm.

ZPL offers the following advantages:

  • Further improvement in corrosion protection
  • Outstanding sliding properties, as a result of which zinc abrasion in the die is prevented
  • Low die wear
  • Longer die life
  • Paintable and printable layer with "anti-fingerprint" properties

Our tasks also include shared process optimisation with our clients – for efficient production.

Our spooling lines are a good example for cooperation and continuous ongoing development – as a result of them, we have been able to increase the running length of the individual strips to as much as 100,000 m. In this process, we connect the strips using state-of-the-art welding technology and coil them up with oscillating motion.

This process is computer-aided and delivers a decisive advantage for our clients' production. They can increase their system running times several times over, thus minimising the set-up times that require intensive personnel involvement, as well as unprofitable machine downtimes.

Our spooling systems:

  • Extension of the running length up to 20 times over
  • Individual spooling width from 100 to 400 mm
  • Spooling weights up to 1,500 kg
