Description Of No.4 Finish Coil
No.4 Finish Coil,we also called no.4 finish stainless steel coil.That is a type of stainless steel surface finish.The no.4 finish is the most popular available today, and typically utilizes.There are various names for it including brushed, polished, satin, and sometimes even nickel finish. It's the factory industry standard in commercial, industrial and residential applications where aesthetics and longevity are important.It's also the most consistent across batches and is easier to match when upgrading or adding to previous installations.The no.4 finish will never fade and is basically ageless, providing you keep it maintained.
No.4,a type surface finish of stainless steel, polished with No.150-240 abrasives.

DESCRIPTION OF STAINLESS STEEL COIL
Stainless Steel Coils are one of the most sought after types of raw material in the construction and manufacturing industries.It was finished steel products such as sheets or strips which has been wound or coiled after rolling Stainless steel coils are normally classified into hot and cold-rolled types according to current products and international standards,which mainly include 200,300,400 series.
High Toughness
With high yield point and tensile strength,stainless steel coils perform resistant elastic deformation and plastic deformation from external force well
Excellent Ductility
With lower carbon and higher nickel contents,stainless steel coils show excellent ductility and tensile-strength,suitable for deep drawing and bending
Strong Corrosion Resistance
Containing 17%-22%chromium,stainless steel coils surface is covered by an oxide film,preventing further oxidation or corrosion
Wonderful Brightness
Through cold rolling,pickling,annealing and leveling,the flatness,smoothness and brightness of stainless steel coils surface are well presented
