Product Introduction

Layer Schematic of Galvanized Steel sheet, gi steel coil

Hot-dip galvanized steel coil is to immerse a thin steel plate in molten zinc, so that a layer of zinc is attached to the surface. It is an effective anti-corrosion method and can provide a long service life of metal materials.


Surface Structure

hot dipped galvanized steel sheet (hdgi)normal spangle coating

Normal spangle

Through addition of certain heavy metal element into molten zinc bath, regular spangle pattern is produced on Hot-dip zinc-coated steel sheet.

hot dipped galvanized steel sheet minimized spangle coating

Minimized spangle

The zinc layer(coating) does Not contain Lead(Pb), which complies with EU WEEE and RoHS directives. This is a non-toxic and environmental friendly material.

hot dipped galvanized steel sheet spangle-free coating

Spangle-free

During hot-dip galvanizing, only a certain amount of aluminum is added to the zinc solution, and lead-free, antimony, and tin are not added to produce spangle-free products.

Main Features of Galvanized Steel

Anticorrosive: 13 years in heavy industrial areas, 50 years in the ocean, 104 years in the suburbs and 30 years in cities.

Cheap: The cost of hot-dip galvanizing is lower than that of other coatings.

Reliable: The zinc coating is metallurgically bonded to the steel and forms part of the steel surface,so the coating is more durable.

Strong toughness: The galvanized steel sheet layer forms a special metallurgical structure that can withstand mechanical damage during transportation and use.

Comprehensive protection: Every part of the plated piece can be galvanized, and is fully protected even in depressions,sharp corners,and hidden places.

Save time and energy: Galvanizing process is faster than other coating methods.

Galvanized steel coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and other industries. Such as building roofs, highway guardrails, sheet metal processing, roof grilles, household appliance enclosures, ventilation ducts, chimneys, kitchen utensils, grain storage and transportation, frozen processing of meat and aquatic products, etc.
