Our environmental protection equipment synchronized with European standards can achieve pollution-free green production
OUR PROCESS

DEGREASING

A hot alkaline or caustic solution removes dirt, oil, grease and soluble markings.

PICKLING

A dilute solution of hot sulfuric acid removes surface rust and mill scale to provide a chemically clean metallic surface. This pickling process, heated to about 150 ° F, attacks the base steel, getting beneath the rust and scale to achieve the adequate cleaning passes thru into the zinc.

DRYING

Fast drying with high-temperature air stream in the underground drying room.

GALVANIZING

This is where the steel actually gets its silver/grey coatings. The article is immersed into a bath of molten zinc heated to about 830 F. During the process, the steel comes up to the bath temperature and the zinc metallurgically bonds to the steel, creating a series of highly abrasion-resistant zinc-iron alloy layers.

INSPECTION

Coating thickness and surface condition inspections complete the process to ensure compliance with the specification. Electronic gauges are used to give quick and accurate measurement readings of the coating.

OUR HONOR

FOR THE LAST 30 YEARS

We are the most trusted leading company in the galvanizing industry.
