For the No.1 stainless steel coil, the origin is very important. Basically, You can classify the origin into private mills and governmental mills.
For No.1, TISCO BAOSTEEL ZPSS is always the best mill with the best guarantee and service
however, some private mills also start to compete with governmental mills, which are much cheaper than the governmental mills, like donate, Qingshan.

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.
Coil Weight Control
Based on client requirement, we can control the stainless steel coil weight to 1-24 tons.
Coil Package
Every coil has to be packed with stronger steel strip and make sure the wooden pallet is strong enough
Loading and locating
Strengthen steel ropes will be applied to make sure the coils will not move during the loading.
Wooden blocks
To get rid of pallet shift during the transportation, wooden blocks will be applied
Eye to door loading
This loading method is easier for clients to get coils unload.
Complicated loading
This loading method is mainly used for special shipping lines or clients who has a high requirement for shipment.
