Continuous Coating is a Steel Sheet Coil to Coil Toll Operation
Zinc is a versatile and practical electroplating metal.
With zinc electroplating surfaces can be produced that have a
light dull gray to a satin silver finish. The appearance can
be retained and protected by using a clear or gold protective
coating. The zinc electroplating provides:
Steel easily accepts zinc electroplating and enhances
roll forming ability.
Lasting corrosion protection on steel.
A controlled thickness of deposit.
Surfaces that have pleasing and desired appearances.
Surfaces that can readily be chromatted for additional
corrosion protection against "white and red rust".
What is Phosphate Coating?
Phosphate coatings are transformations of metal substrates into a
new non-metallic and non-conductive properties.
They are widely used in the manufacture of products for principal reasons.
To precondition surfaces to receive and retain paint and to protect
surfaces against under paint corrosion.
To prepare surfaces for bonding with plastic coating and adhesives.
To precondition surfaces for metal forming operations, such as cold
extrusion and breaking in friction bearing surfaces by providing for
drawing compounds and lubricant.
To improve corrosion-resistance by providing a base for waxes and
rust preventive oil. By far the most wide spread use of phosphate
coating is to prolong the useful life of paint finishes.
Phosphate coatings are inert to everyday envioronment. They perform well in
high humidity areas, hot and cold day and rainy seasons where white rust or
storage stains are a constant threat. Phosphate hot dipped steel's painted
life is greatly extended by stopping lateral corrosion that occurs underneath
