Cold rolled steels of the highest quality
Cold rolled steels
Many years of experience and state-of-the-art technologyWe offer our customers a wide range of cold-rolled steels – of the highest quality at competitive prices. In addition to a high degree of flexibility and readiness to deliver, we guarantee exact compliance with the specified chemical and mechanical values.
Surface finishing by electrolytic galvanizing and/or subsequent dimensional cutting is also possible for us. We offer all our customers coil systems with volumes of over 200,000 meters of metal strip per coil. This further development means a considerable advantage for our customers, because personnel-intensive setup times and machine downtime can be avoided.
Process steps of cold rolling
All in one handAll process steps of cold rolling – from thickness reduction and heat treatment to re-rolling and subsequent finishing – are perfectly coordinated and continuously monitored by our quality and process management system. Our rolling stands are equipped with the latest technology and guarantee consistently high quality production.
Because the heat treatment of the steel is decisive for the material properties of the end products, we work with roller hearth annealing furnaces. In contrast to the more static bell annealing, these allow continuous homogenization of the metal structure.
Product overview cold rolled steels
The right material for every application
Classic cold strip
Cold-rolled strip is used in a wide variety of applications. It meets high requirements for forming behavior, dimensional tolerances and surface finish, which offers our customers decisive advantages!
HFP cold rolled strip is ideal for all punching, bending, drawing and deep drawing purposes. A wide variety of components can be manufactured for diverse industries, ranging from ball bearing housings to roll cutting and punching strips, hose clamps, headlight reflectors, electrical equipment, office supplies and tubing to safety parts of all kinds.
Grades:
DC 01, DC 03, DC 04 acc. DIN EN 10139 / Structural steel – St 37 / Special grades on request
Treatment Conditions:
from LG to C690
APPLICATIONS
The case-hardened steel group comprises carbon steels with low carbon content and good formability and fineblanking quality. Due to case hardening, the components exhibit low-wear surface layers with high hardness and sufficient toughness in the core. They thus combine numerous properties and application possibilities in a wide range of industries. You can also carburize or carbonitride sections to increase wear resistance.
Grades:
C 10 E, C 15 E / ➔ acc. DIN EN 10132
Treatment Conditions:
Depending on customer requirements, we supply treatment conditions ranging from soft annealed to highly work-hardened.
Quenched and tempered steels
The material group of quenched and tempered steels stands for fracture strength, service life and wear resistance. Due to these properties, quenched and tempered steel is always used where high strength, yield strength and additionally high toughness must be present in highly stressed machine parts.
Grades:
C 22 E, C35 E, C 45 E / ➔ acc. to. DIN EN 10132
Treatment Conditions:
Depending on customer requirements, we supply treatment conditions ranging from soft annealed to highly work-hardened.
Spring steels
Spring steel is a model of resilience. This group of materials is characterized by homogeneous microstructures and optimum surfaces. It stands for above-average durability, dimensional stability and consistent quality in every end product.
Spring steel obtains its special properties through special treatment in the production process, whereby the uniform distribution of the carbon content is of particular importance. It undergoes multiple rolling operations and repeated heat treatments in numerous steps – this is how we ensure optimum quality for your products!
Grades:
C 67 S – C 100 S / ➔ acc. to. DIN EN 10132
Treatment Conditions:
Depending on customer requirements, we supply treatment conditions ranging from soft annealed to highly work-hardened.
Electrolytically Galvanized Strip & ZPL (Zinc Plus Paint)
In addition to the product range of classic cold rolling mills, we can also offer our customers electrolytically galvanized strip. The zinc coating provides excellent corrosion protection:
In cooperation with our customers, we have developed a product that remedies the problem of zinc abrasion in the processing of galvanized strips – ZPL (Zinc Plus Paint). Here, an organic coating system is applied immediately after electrolytic galvanizing. This results in a colorless, uniform, highly slippery coating with a dry film thickness of 0.50 – 3.00 µm, which can of course also be supplied in any desired color.
ZPL offers the following advantages:
- Further improvement of corrosion protection
- Excellent sliding properties, preventing zinc abrasion in the mold
- Less tool wear
- Longer tool life
- Oil-free processing is made possible
- Paintable and printable layer with “anti-fingerprint” properties
Coiled metal strips
More running lengthIn order to increase the running lengths, we join the metal strips using the latest welding technology and oscillatingly wind them onto new spools. In this way, we reduce set-up and downtimes in your production.
- Strip widths from 1.5 mm up to 60 mm
- Extension of the running length to over 200,000 meters in one core depending on the material
- Individual installation widths from 100 to 400 mm
- Special decoiling racks with winding widths of 800 mm and maximum winding weights of 2,500 kg
