How is the surface treatment performed after welding SGCC sheet?
After welding, SGCC sheet requires cleaning the weld seam and heat-affected zone (HAZ) of zinc nodules and spatter. Then, zinc-rich paint or spray protection can be applied to restore corrosion resistance.
Other Questions
Is SGCC sheet environmentally friendly?
SGCC sheet itself is a recyclable material and meets certain environmental requirements. However, the production process may produce some pollutants, which require appropriate environmental protection measures.
What is the price of SGCC sheet?
Compared to ordinary cold-rolled steel sheet, SGCC sheet is more expensive, influenced by factors such as zinc layer thickness, specifications, and market supply and demand.
Can SGCC sheet be produced domestically?
Currently, no domestic steel mills can produce high-quality SGCC sheet, and the company relies primarily on imports.
How does SGCC sheet perform in high-temperature environments?
Prolonged exposure to high temperatures can cause oxidation of the zinc coating, reducing corrosion resistance. Therefore, SGCC sheet is not suitable for long-term use in high-temperature environments.
