Galvanized Automotive Steel

 

Galvanized automotive steel is specially used for the production of automotive Body Panels, Structural Parts, and Reinforcements, and has a zinc coating on the surface to prevent the steel from rusting and corrosion.

 

Parameter	Specification
zinc Coating	60–275 g/m²
Thickness	0.3 mm – 3.0 mm
Grade	DX51/52/52/54D+Z
Surface Finish	Smooth, defect-free

 

 

 

 

 

 

Hot-Dip Galvanized (HDG)

Provides durable and thick zinc layers.

Ideal for structural and exposed components.

 

Electro-Galvanized (EG)

Offers uniform, thinner coatings.

Perfect for painted surfaces and aesthetic applications.

 

Type	Examples	Applications	Key Properties
Commercial Quality (CQ)	DX51D+Z, ASTM A653 CS	Non-structural parts, interior components	Good formability, moderate strength.
High-Strength Low-Alloy (HSLA)	HX260LAD+Z, S350GD+Z	Chassis, reinforcements	High strength with good weldability and corrosion resistance.
Advanced High-Strength Steel (AHSS)	DP600+Z, TRIP780+Z	Crash-resistant parts, safety structures	Excellent strength-to-weight ratio, energy absorption.
Bake-Hardenable (BH)	BH220+Z	Exterior body panels (doors, roofs, hoods)	Gains strength during baking, enhancing dent resistance.
Martensitic and PHS	MS1200+Z, PHS1500+Z	Safety-critical components (B-pillars, bumpers)	Exceptional strength after forming.
