Popular Galvanized Steel Grades: A Quick Guide

Galvanized steel, known for its corrosion resistance, is widely used in construction, automotive, and manufacturing. Here’s a quick overview of common types and their uses:

• GI (Galvanized Iron): Standard zinc coating, ideal for roofing, fencing, and general-purpose applications.

• GA (Galvannealed Steel): Zinc-iron alloy coating, offers better paint adhesion, used in automotive panels and appliances.

• HDG (Hot-Dip Galvanized): Thick zinc layer, excellent for outdoor structures like bridges, poles, and pipelines.

• EG (Electro-Galvanized): Thin, uniform coating, perfect for electronics, automotive parts, and small components.

Key Uses:

• GI: Roofing, fencing, ductwork.

• GA: Automotive bodies, appliances.

• HDG: Outdoor structures, industrial equipment.

• EG: Electronics, precision parts.
