Color Coated Steel Sheet and Steel Strips (GBT 12754-1991)
Color coated steel sheet and steel strips is a product that has a thick zinc coating on top of the steel sheets and strips for corrosion protection. The product is widely used for architectural purposes and industrial production. The zinc coating of color coated steel sheet and steel strips provides a corrosion-resistant barrier that is highly durable and is able to withstand the ravages of environmental conditions such as humidity, dust, and salt spray.
The steel sheets and strips used in color coated steel sheet and steel strips are typically made from a hot rolled steel. The hot rolled steel is first cleaned, then primed and painted. The painting process uses a polyester coating which is applied with a special machine. Once applied, the polyester coating is cured at elevated temperatures for hardness and strength. The color of the coating is determined by the type of colorants used in the application process. These colorants include organic and inorganic materials such as iron oxide, mica, and titanium dioxide.
Color coated steel sheet and steel strips possess superior properties that make it ideal for many applications. It has excellent corrosion resistance, an optimal combination of strength and formability, and good electrical conductivity. The added zinc layer also provides excellent weldability and at the same time, is a great barrier to mechanical and chemical damage. The product is also easy to repair and maintain due to the zinc layer that creates a sacrificial barrier to corrosion. This also allows the coating to be selectively removed without damaging the base material.
Color coated steel sheet and steel strip is also an economically viable solution as it has comparatively low lifetime cost and can last up to several decades. With the proper selection of steel, the product has a much longer lifespan than other types of steel and can withstand harsh weather conditions. Additionally, the product does not require costly maintenance. The reason for this is that most of the maintenance needs for this product are primarily for its coating. Periodic cleaning and painting can help keep the product in pristine condition for a long period of time.
In conclusion, color coated steel sheet and steel strip is an ideal product for many industries that require superior corrosion protection and legendary strength. The product, in addition to being highly cost-effective, is also easy to maintain and repair, allowing for relatively low maintenance costs. Furthermore, the product has a much higher longevity than other types of steel, making it a desirable choice for industry professionals.
