There are many series of metal signs according to different materials. Sichuan Jaguar Sign Experss Co.,Ltd is professional letter and sign manufacturer with over 20 years experience which will introduce you to stainless steel sign in very detail today.
1.What is the stainless steel sign
stainless steel sign is an advertising sign made of stainless steel as a material. The craft include etched, fabricated, laser cuting, printing etc. Most of the stainless steel signs finished effect is made by etched technology. The advantage is that can get the characteristics of beautiful patterns, clear lines, appropriate depth, flat bottom surface, full color, uniform drawing and uniform surface color.
2.The feature of stainless steel material
Stainless steel is mainly composed of stainless steel and acid-resistant steel. In short, steel that resists atmospheric corrosion is called stainless steel, and steel that resists chemical corrosion is called acid-resistant steel. According to different element content in stainless steel, they can be divided into five categories: ferritic stainless steel, martensitic stainless steel, austenitic stainless steel, austenitic-ferritic stainless steel and precipitation carbonization.
3.The production of stainless steel sign
The production process of stainless steel sign is more difficult than copper and aluminum plates, but it has good resistance to weather and corrosion. It is very beautiful after etching, polishing and brushing. Stainless steel etched craft is electrochemical corrosion, also known as electrolytic corrosion. The corrosion process of stainless steel can show damage and some substances affecting the surface, such as: dust, floating iron powder or embedded iron, rust spots, grinding burr, welding arc spot, welding spatter, flux, welding defects, oil and grease, residual adhesives and paint. The corrosion generally is not throughout the entire surface, but in the defect or its surrounding, and most of the surface is not eroded. This method is the current sign manufacturers commonly used.Therefore, the feature of stainless steel signs is: will not rust, long service life, good weather resistance, can choose brushed and polished finish effect,
4.Common models of stainless steel
Common models of stainless steel are 201, 304, 316, etc. The 201 stainless steel is high in manganese, the surface is very bright with dark light, and the manganese is high and easy to rust.
The 304 stainless steel contains more chromium, the surface is matte, does not rust, and the corrosion resistance is better than 201. The 316 stainless steel also has good chloride attack properties and is therefore commonly used in marine environments.
The above is all introduction of the stainless steel sign by the Sichuan Jaguar Sign Experss Co.,Ltd - Professional letter and sign manufacturer since 1998.
