What is hairline finish ?
The hairline finish is a design finish in which the surface of the metal has a straight line of hair, like the straight hair of a long woman. This hairline finish is a general-purpose design finish that has been used for a long time
What is No.4/#4 brush finish ?
No.4, also called #4, satin or directional finish, is an unidirectional finish obtained with a 100-400 grit abrasive depending on requirements. High grit numbers create finer polishing lines and more reflective finishes.
The features of hairline finish sheet
Hairline referred to as "the HL",it's grain as fine as hair, straight and continuous, delicate with oil paints on the surface. It has slightly lower reflective rate than satin stainless steel sheet.
Hairline is one of the most authentic and beautiful metal surface treatments. Combined with matte effects, hairline can further enhance the texture of metal itself.
The features of No.4/#4 finish sheet
The #4 brushed finish is the most popular available today, and typically utilizes . There are various names for it including brushed, polished, satin, and sometimes even nickel finish.
It's the de facto industry standard in commercial, industrial and residential applications where aesthetics and longevity are important. It's also the most consistent across batches and is easier to match when upgrading or adding to previous installations.
The #4 brushed finish will never fade and is basically ageless, providing you keep it maintained.
The characteristics and advantages of brushed stainless steel plates are as follows:
1.Corrosion Resistance: Stainless steel itself possesses excellent corrosion resistance, and the brushing process enhances its corrosion resistance even further. This makes brushed stainless steel plates ideal for use in humid, corrosive environments or applications requiring long-term durability.
2.Strength and Wear Resistance: Brushing treatment increases the surface hardness and wear resistance of stainless steel plates, making them more resistant to scratches, abrasion, and damage.
3.Aesthetic Appeal: Brushing treatment imparts a unique texture and sheen to stainless steel plates, enhancing their visual appeal. This makes brushed stainless steel plates highly popular in applications with high design aesthetics, such as home appliances, decorative materials, and architecture.
4.Easy to Clean and Maintain: The smooth surface of brushed stainless steel is less prone to dirt and is easy to clean and maintain. This makes it an ideal choice for food processing equipment, sanitary fixtures, and medical devices.
5.High-Temperature Performance: Stainless steel already exhibits excellent high-temperature performance, and brushing treatment further enhances its heat resistance. This ensures stability and reliability in high-temperature environments.
6.Bendability and Processability: Brushed stainless steel plates possess a degree of bendability, making them suitable for crafting various shapes and components. They can also be cut, welded, and processed to meet different application needs.
7.Longevity: Due to their corrosion resistance and wear resistance, brushed stainless steel plates typically have a long service life, reducing replacement and maintenance costs.
In summary, brushed stainless steel plates offer outstanding corrosion resistance, strength, aesthetics, and processability, making them suitable for various applications including construction, manufacturing, food processing, medical, and decorative purposes.
