DIN EN 10130, 10209 and DIN 1623
Cold rolled steel is also part of our product portfolio. Cold rolled steel is excellent for cold forming. This product group assigned the grades DC01 to DC07, DC01EK to DC06EK, DC03ED to DCO6ED and S215G to S325G. The grades are classified according to the maximum permissible yield strength and can be subdivided as follows. DC01-This grade can be used for simple forming work, for example Bending, embossing, beading and pulling are used. DC03 - This grade is suitable for forming requirements such as Deep drawing and difficult profiles suitable. DC04 - This quality is suitable for high deformation requirements. DC05-This thermoforming grade is suitable for higher forming requirements. DC06-This special deep drawing quality is suitable for the highest deformation requirements. DC07 This super deep drawing quality is suitable for extreme deformation requirements.
Enamelled grades
The steel grades DC01EK, DC04EK and DC06EK are suitable for conventional single-layer or double-layer enamelling. The steel grades DC06ED, DE04ED and DC06ED are suitable for direct enamelling as well as for enamelling according to the two-layer / one-firing method and for special applications of two-layer enamelling for low-distortion enamelling.
Surface type
Surface A
Mistakes such as pores, small grooves, small warts, slight scratches and a slight discoloration that does not affect the ability to reshape and adhere to surface coatings are permitted.
Surface B
The better side must be free from defects so that the homogeneous appearance of a quality finish or an electrolytically applied coating is not impaired. The other side must at least meet the requirements of surface type A.
Surface finish
The surface finish may be particularly smooth, dull or rough. If no details are given when ordering, the surface finish will be delivered in a matt finish. The four surface finishes listed correspond to the center roughness values in the following table and must be tested in accordance with EN 10049.
Hot Rolling Line
Hot-rolled coil is a development of the varieties of steel the current markei demand many concentraced in the automobile industry,compressor industry,machinery manufacfuring,processing and distribution industry,fan industry,motorcycle industry,steel furniture,hardware accessories,electrical cabinets and shelves of various shapes,such as stamping parts. As technology advances,hot-rolled pickling coil has been related to household appliances,containers,electrical control cabinet and other industrise,including the use of pickling hot-rolled coil instead of cold plate in some industry development is rapid.
Hot rolled steel coils
Hot rolled steel coils are hot rolled steel made into relatively thin flat pieces and wound up into coils, resembling a wound steel strip. Hot rolled steel coils are widely used in applications like home appliances where saving weight and aesthetic value is deemed essential. It is also frequently used as a work-piece for the further production of cold-rolled products. As a specialized hot rolled coil supplier, CUMIC Steel keeps developing and provides high quality china hot rolled coil with competitive price.
Forging process of stainless steel plateStainless steel plate is used more in our life, and its processing industry is also more diverse, mainly including cold rolling, calcined and hot rolling, etc. Today, we will introduce the calcined stainless steel plate process:- The solution of the stainless steel tube processingStainless steel pipe now more and more widely used, due to its good corrosion resistance has played a vital role in engineering construction, in the process of production we need a solid solution for stainless steel tube processing, the main purpose is to obtain certain martensite increase the hardness of products.

Production process and classification of aluminum ingotsThe production of aluminum ingots is composed of bauxite mining, alumina production, aluminum electrolysis and other production links.
The bauxite is mined first, and the aluminum ore powder is produced through processes such as washing and grinding, and then alumina is obtained through four complicated processes such as roasting.- What are Aluminum Coils ？Before we go into the uses of aluminum coil, it is important to understand what it is. An aluminum coil is a piece of aluminum roll, as opposed to a flat sheet. It has a hollow cylindrical core that is wound around the coiled material. This allows the inner diameter of the coil to be formed. Coils can be pre painted, diamond-coated, heat-treated, and non-heat treated. Here will talking uses of aluminum coils.
