Detail Matters of stainless strip
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.
For each and every batch,Original MTC will be provided to guarantee the origin.
