Application of Yieh United Stainless Steel Coil
With good performance of resisting to different kinds of corrosion, our stainless steel coil can be used in architectural, kitchen equipment, decorative applications, aircraft exhaust manifolds, expansion joints, furnace parts, heating element tubing, heat exchangers, household appliances, metal molding, metal trim, cabinet hardware, and hinges.
You might wonder why you choose Yieh United HL stainless steel sheet instead of others. The answer is simple. It’s because our Polished Stainless Steel Sheet is simply the best of the best.
Here are some reasons:
1. Raw Material
Our coil is originated from Taiwan, Krupp, Columnbia, Baosteel, TISCO, and other major steel production of high quality stainless steel. If coil is not from a good standard factory, the coils surface may have some problems, especially for the edge. They are not easily leveled and processed, after processing, there will be some vertical strips which make the surface not expected. Here is an example to show the bad finished surface is due to the material origin.
In the processing, sandbelt working time is a key factor for controlling the surface quality. If the sandbelt is new, the polished lines will be very rough and thick, and have less reflective effect.After the sandbelt has been used for a long time depending on the quality of the sandbelt,the polished strips maybe too shallow,which cannot reach the expected effect.
After the surface processing, choosing the PVC film will have much influence on afterwards application. We have several kinds of film to be choosen, and they are suitable for different application. The film not only serves as a protection but also affect the afterwards processing.
Laser film is considered to be one of the best film. The thickness is at least 10c. Laser film normally has higher melting degree than other film, which will not be melted and sticked on the surface after heat treatment. Here is an example of normal film after heat treatment.(Please confirm the downstream processing, and then decide which film is to be applied.)
This kind of film cannot undertake high temperature treatment, but it is relatively thicker and more sticky than Chinese Origin film. It can be used in most mechanical process and have a good performance.
>>Transparent blue film and Chinese black and white film
These two kinds of film are relatively not considered to be good qualified, which means they are not very sticky, and not thick enough. The thickness ranges from 2c to 10c. Most customers apply these film in many ordinary processing. When the downstream need bending, or deep drawing, the film may suffer from cracking.[/restab][/restabs]
