CCY - Professional Stainless Steel Grinding Services for NO.4/NO.6/HL/SB Finishes-CCYSTEEL

Grinding - NO.4 / NO.6 / HL / SB

A grinding finish on stainless steel, also called Graining, Brushing or Satin, is made from cold rolled 2B / BA stainless steel.
The process uses 150 / 180 / 240 / 320 grit abrasives for a smooth, unidirectional finish. The finish features short, parallel lines that are uniform and run evenly along the steel, making it perfect for applications where lower reflectivity or gloss is desired.
CCY offers whole-oil grinding, which gives stainless steel a refined and long-lasting appearance. This method outperforms wet and dry grinding, resulting in a finish that's both smooth and shiny, ensuring the steel stays looking great over time.

Range Hood

No matter if it's a European, Chinese, or side-suction range hood, how oil and smoke affect the hood's surface is really important for the people who make these things. CCY produces No. 4 stainless steel sheets that are processed by clients into range hoods. The grinded stainless steel we provide makes the range hoods look really nice. It doesn't get damaged by oil and smoke, so it stays looking good and lasts a long time.

Whole-Oil Grinding Technology - For a Great Look

CCY use Whole-Oil Grinding machine with sand belts to grind the finish. This is an unique technique that uses only oil to polish the steel. It has two big benefits compared to dry and wet grinding:

1. The oil helps to sweep away most of the tiny metal shavings that come off during the grinding, which helps the steel maintain high corrosion resistance on the grinding surface.

2. The oil-based process helps keep the steel flat and straight, even when it gets hot from grinding.

The cost of the grinding process might seem small compared to the whole purchase, but it can make a big difference in which company people choose to work with. In this case, CCY can help you win in the competition.
Those competitive mill factories CCY is working with

We source our stainless steel from top-tier factories to ensure the highest quality. Some of the major mills we partner with include Jisco, Baoxin, Posco, Tisco, Lisco, Outokumpu, Yuanlong, JFE, NSSC, YJGF, Delong, HWHG etc.

We often purchase large coils weighing between 11~12 tons from these factories driectly. In this way, we receive the highest quality stainless steel. These mills have stringent quality control processes and provide MTC for every batch, confirming that the material meets international standards like EN, JIS, AISI, ASTM, GB, DIN. This consistency is crucial for our products.
How CCY Ensures Top-Notch Satin Finish Quality

At CCY, we're all about quality. When it comes to our satin finish stainless steel, we keep a close eye on every step of the process.

We check the raw materials when they arrive, look at the color of the product, do T-bend and impact tests, and even put the steel through a salt-spray test. Plus, we have people who check the quality by hand, do tensile tests, and make sure the packaging is perfect for shipping.

During production, at least two quality inspectors are always on hand to confirm the surface quality of the products. This extra layer of inspection ensures everything meets our high standards. All this makes our stainless steel strong against corrosion.
