304 stainless steel Coil
Stainless steel 304 is an austenitic grade of stainless steel that contains high nickel content, typically somewhere between 8 and 10.5 percent by weight and a high amount of chromium that comprises approximately 18 to 20 percent by weight. The lower carbon content of grade 304 stainless steel minimizes chromium carbide precipitation from welding and the alloy’s susceptibility to intergranular corrosion.
The alloy also exhibits excellent toughness, even down to cryogenic temperatures. On the other side of the spectrum, in terms of resistance to oxidation, this stainless steel alloy can be exposed to temperatures of about 1650F continuously appreciable scaling.
Type 304 can be easily welded using common fusion and resistance methods, like most other austenitic grades.
Normall， Different mills will apply 3 types tolerance, like 1.0mm, there will be 0.91-0.92mm/0.94-0.96mm/ 0.98-1.01mm. 3 stages to apply for different application.
Width tolerance mainly depends on the slitting and cutting machine. We use Taiwan and Italy machinery, which can guarantee +/-0.05 to +/-0.1mm
Diagonal Tolerance is a key factor to show whether the cut is correct or not. The normal tolerance is +/-2mm。

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.
There are normally 2 types of blue transparent film, one is the for deep drawing, another one is normal protection film.
Stainless Steel Coil Packing and Loading Solution
Coil Weight Control
Based on client requirement, we can control the stainless steel coil weight to 1-24 tons.
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.
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.
This loading method is mainly used for special shipping lines or clients who has a high requirement for shipment.
For these countries, local agant is available to offer face to face meeting
We commit to respond every inquiry within 10 hours on week days
