316/316L/321 300 Series Stainless Steel Sheet/PlateThe surface of stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to corrosion of acids, alkaline gases, solutions and other media. It is an alloy steel that is not prone to rust, but it is not absolutely rust-free.- 2205/2507/904L Duplex Stainless Steel Sheet/PlateThe surface of stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to corrosion of acids, alkaline gases, solutions and other media. It is an alloy steel that is not prone to rust, but it is not absolutely rust-free.
- 309/309S/310/310S Stainless Steel CoilStainless steel coils are divided into austenitic, ferrite, martensite, dual phase (ferrite austenite) cold rolled stainless steel coils and hot rolled stainless steel coils.
- 410/420/430/440 400 Series Stainless Steel CoilStainless steel coils are divided into austenitic, ferrite, martensite, dual phase (ferrite austenite) cold rolled stainless steel coils and hot rolled stainless steel coils.
- SGCC Galvanized steel Plate/SheetGalvanizing is an economical and effective rust prevention method that is often used. About half of the world's zinc output is used in this process. Galvanized steel plate is to prevent the surface of the steel plate from being corroded to extend its service life. A layer of metal zinc is coated on the surface of the steel plate, which is called galvanized steel plate.
- Z40-Z275 Galvanized steel Plate/SheetGalvanizing is an economical and effective rust prevention method that is often used. About half of the world's zinc output is used in this process. Galvanized steel plate is to prevent the surface of the steel plate from being corroded to extend its service life. A layer of metal zinc is coated on the surface of the steel plate, which is called galvanized steel plate.
- Hot dip galvanized steel pipe/tubeGalvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Welded steel pipe with hot-dip or electro galvanized coating on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life.
- Z40-Z275 Galvanized steel pipe/tubeGalvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Welded steel pipe with hot-dip or electro galvanized coating on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life.

LATEST NEWS
- Pickling of stainless steel water pipesAlthough stainless steel plumbing is relatively corrosion resistant and protected by an oxide layer, we also need to take care of it.
- Cold cutting usage of stainless steel sheetsCold cutting is a cutting method. Stainless steel plate using the cutting process does not produce high temperature technical means or methods, so that the material being cut to maintain the original material characteristics, the cutting process temperature change is not large, usually temperature rise of no more than 40 degrees Celsius.
- How to maintain the surface quality of stainless steel pipeStainless steel tube has a good surface finish. It can be used as a decorative tube. It can also be processed and used as a heat exchanger tube according to its characteristics of high temperature resistance and rust prevention. But even the best surface has to be used and maintained by the user reasonably.
- Introduction to the types of stainless steel plateThis stainless steel has two main characteristics. First, austenitic stainless steel contains a large amount of chromium in the production process. Items produced from this material are more resistant to corrosion. Second, these items tend to be non-magnetic, although they can become magnetic through the cold forming process.
