Frequently asked questions
Q1：How to choose the type of zinc coating (GI/GA/ZM)?
A:GI (pure zinc): general anti-corrosion, low cost, suitable for pre-spraying treatment.
GA (zinc-iron alloy): excellent welding performance, suitable for automotive structural parts (splash reduction 40%).
ZM (magnesium-aluminum coating): salt spray resistance is improved by 3 times, suitable for coastal or chemical environments.
Q2：How many countries you already exported to?
A:We have exported to America, Canada, Brazil, Chile, Colombia, Russia, Ukraine, Thailand, Myanmar, Vietnam, India Kenya, Ghana,somalia and other African countries.Our export experience is rich, we familiar with different market demands, can help customers avoid a lot of trouble.
