Mother Coil Origin
Stainless steel strip production quality mainly depends on 2 aspects.
- Mother Coil Origin
For hardness controlled products, like 1/2H,3/4H,FH and SFH, the mother coil quality is the most important fact affecting the production rate and surface condition. Normally, POSCO has the best quality for stainless steel strip downstream processing.
2. Rolling machinery
4 rolled/8 rolled/20 rolled, the more rolls in the machinery, it means high precision, and better surface condition. of course, the cost is different.

Stainless Steel Slit Strip
Stainless slit strip is produced directly from slitting of the mother coil. It is used as pipe production.
Slit coil surface
Surface includes 2B/BA/2B/No.4/HL/8K
Slit strip Width
Minimum 5mm, maximum 750mm
Stainless Steel Precision strip
When mentioning “precision strip”, it always refers to a thickness below 0.23mm. The minimum thickness is 0.05mm, and with this thickness, the width can be maximum of 720mm.
Stainless precison strip surface
By default, the surface is “BA”, it is brighter than 2B, but less bright than real BA. If clients need a better shining condition, we can do polishing for one side.
Stainless Strip Application
Stainless strip is widely used in different industries including tubing, mobile phones, cars, chemical, medical, and other harsh environment industries.
World projects
For these countries, we are ready to project meeting service
Application Cases Analysis
Every detail of stainless steel property has an affection on the application of different field.
MTC from collaborative Mills
For each and every batch， Original MTC will be provided to guarantee the origin.
PVC Film
PVC film is one of the most important factor when purchasing stainless steel material. Basically, 3 types of PVC films are typically applied.
PE50/PE80 black and white film
This is the most widely used film, the thickness normally ranges from 50 micron to 80 microns. There will not be any special function except protection.,
Laser Film(Novacel 4228)
Laser cutting is often applied as a downstream processing. Laser film is a film that can undertake high temperature. If clients apply the wrong pvc, after laser cutting, the pvc will be wrinkled and sticky to the surface.
Transparent Film
There are normally 2 types of blue transparent film, one is the for deep drawing, another one is normal protection film.

Detail Matters
Stainless strip is widely used in different industries including tubing, mobile phones, cars, chemical, medical, and other harsh environment industries.
Coil ID
250/300/400/508mm coil ID is available from our factory. we guarantee the coil ID can suit clients’ machinery.
Chamber Rate
Chamber Rate is a key factor affecting the welding tube process, we guarantee the chamber rate is lower than
Bur Level
Bur level is well controlled to less than 5%. However, some clients need deburring service and round edges, we can provide this service.
Bundling direction
When opening the slit strip, if people can know which direction the strip is bundled, it will be much easier to load the material.
Coil Separator
for small child coils，especial for package “eye to sky”, between each and every child coil, there must be some wooden stick to separate each child coil.
Package method
For precision strip, wooden box will be applied to protect the strip from being damaged.
