Stainless steel coils can be surface treated in a variety of ways, each giving them unique appearance characteristics and performance enhancements. The following are several common stainless steel coil surface treatment methods and their characteristics:
1. Mirror treatment
Processing method: Through polishing technology, mechanical or chemical polishing methods are used to make the surface of the stainless steel roll as smooth as a mirror, reflecting a bright luster.
Features:
Beautiful appearance: The mirror-treated stainless steel roll has a high surface finish, which can reflect clear light and shadow, improving the overall beauty of the product.
Easy to clean: The surface is smooth and dirt is not easy to adhere to, making cleaning more convenient and faster.
Corrosion resistance: Although the mirror treatment itself does not directly enhance corrosion resistance, the smooth surface helps reduce the contact area with corrosive substances and indirectly improves corrosion resistance.
2. Drawing treatment
Treatment method: A layer of rough texture is formed on the surface of the stainless steel coil through mechanical or chemical methods, showing a brushed effect.
Features:
Unique texture: The brushed treatment gives the surface of the stainless steel roll a rustic and fashionable feel, improving the texture of the product.
Anti-Fingerprint: The rough texture helps reduce the visibility of fingerprints and scratches, making the product more durable.
Anti-skid: In situations where anti-skid is required, brushed processing can provide a good anti-skid effect.
3. Pickling treatment
Treatment method: Chemical pickling is used to remove oxide scale, rust and other undesirable substances on the surface of the stainless steel coil to make the surface clean and smooth.
Features:
Smooth surface: After pickling treatment, the surface of the stainless steel coil becomes clean and smooth, which improves the appearance quality of the product.
Good corrosion resistance: The pickling treatment not only removes surface impurities, but also enhances the corrosion resistance and scratch resistance of stainless steel.
Stable quality: Due to the meticulous and comprehensive production process, the pickled stainless steel coils have very high quality stability.
4. Remove black oxide
Treatment method: It mainly deals with the black oxide scale produced during the processing of stainless steel. Commonly used methods include sandblasting (shot) method and chemical method.
Features:
Restoring the true color: Remove the oxide scale through sandblasting or chemical methods to restore the true color of the stainless steel, making it show its original silvery white color.
Environmentally friendly and pollution-free: The modern chemical method uses pollution-free pickling passivation paste and normal temperature non-toxic cleaning fluid, which meets environmental protection requirements.
Strong applicability: For large and complex stainless steel products, natural whitening treatment has good applicability.
5. Surface coloring treatment
Treatment method: Through chemical oxidation, electrochemical oxidation, ion deposition oxide, high temperature oxidation or gas phase cracking, various colored films are formed on the surface of the stainless steel coil.
Features:
Rich colors: Stainless steel coloring can give products a variety of color options and increase the variety of products.
Wear resistance and corrosion resistance: Coloring treatment not only beautifies the appearance of the product, but also improves the wear resistance and corrosion resistance of the product.
Diverse processes: There are various coloring treatment methods, and the appropriate process can be selected according to specific needs and product characteristics.
Classification of stainless steel pipes1. Classification by production method:
(1) Seamless tubes - cold drawn tubes, extruded tubes, cold rolled tubes.
(2) Welded pipe:
(a) Classification by process - gas shielded welded pipe, arc welded pipe, resistance welded pipe (high frequency, low frequency).
(b) According to welding seam - straight seam welded pipe, spiral welded pipe.
2. Classification according to cross-sectional shape: (1) circular steel pipe; (2) rectangular pipe.
Spiral steel pipe stacking requirements1. The principle requirement for stacking spiral steel pipes is to stack them according to types and specifications on the premise of ensuring stable stacking and ensuring safety. Different types of materials should be stacked separately to prevent confusion and mutual erosion;
Difference Between Straight Seam Steel Pipe and Spiral Steel Pipe
Advantages of Using Carbon Steel in ConstructionSteel is an alloy metal, which means it’s a combination of several types of elements. In the case of steel, this is a combination of iron, carbon, and trace elements. It has a number of advantages for construction applications due to the fact that it’s fairly inexpensive to manufacture and has a very high tensile strength.
What determines the type of steel is the ratio of elements used to produce it, and it’s the magic formula of the carbon steel alloy created that makes it preferred for many projects. While there are thousands of different types of steel, these types are generally bucketed into four categories: carbon steel, alloy steel, stainless steel, and tool steel.- Anti-corrosion steel pipe classificationPN8710 anti-corrosion
When there are many types of corrosive media in steel pipes, such as acids, alkalis, salts, oxidants and water vapor, the coating must be chemically inert and resistant to acid, alkali and salt corrosion. The coating film should have a dense structure, good waterproof permeability and strong adhesion. , tough and plump. In this case, IPN8710 anti-corrosion is suitable. 
Global crude steel production fell 4.3% year-on-year in MarchOn April 23, the World Steel Association (WSA) released global crude steel production data for March. In March, crude steel output in the world's 71 countries and regions included in the statistics was 161.2 million tons, a year-on-year decrease of 4.3%. In the first quarter of this year, crude steel output in the world's 71 countries and regions included in the statistics was 469 million tons, a year-on-year increase of 0.5%.
