We hold expertise in providing a qualitative range of Patented Steel Strips to our clients at affordable prices. High carbon steel is an ideal material for custom flat springs, custom clips, and custom sheet metal stampings. High Carbon Steel Strips combines ease of fabrication with good strength and surface finish, is valued for its strength properties and operates at significantly higher levels than the mild steel grades. cold-rolled spring steel strips are gaining popularity in various industries. They are increasingly being implemented in engineering projects, through a fairly large number of small component manufacturers, parts and machine components.By making the right choice to buy steel strips, we reduce the amount of waste produced, thereby saving time and space. With a constant focus on the needs and requirements of our customers, we have created a unique offer.

Spring steel strip is used to build springs for a great variety of purposes. Below especially the cold rolled (carbon as well as stainless) spring steel strip will be described in detail. The most common production width of spring steel strip is about 300 mm (11.811 inches). As a matter of course spring steel strip can be slit or cut to length (sheets). We supply a very wide range of high carbon and alloys, covering the most stringent industrial requirements. We have also developed a unique know-how in the design of custom solutions for special applications.

75 steel - C75S - Carbon spring steel with low hardening capacity for lightweight springs for oil hardening. It is characterized by resistance to abrasion and high strength. Used for low-loaded springs and springs, spring parts, clock springs, saws for cutting stones in the form of tapes and sheets.
