0.2mm Z60–Z180 Hot Dipped Galvanized Steel Strip with 20–630mm Width for Slitting and Industrial Fabrication

0.2mm Z60–Z180 Hot Dipped Galvanized Steel Strip with 20–630mm Width for Slitting and Industrial Fabrication

1. Product Overview

Hot dipped galvanized steel strip is mainly used in narrow-width processing where corrosion resistance, stable strip dimensions, and continuous feeding performance are required. Compared with full-width galvanized coil, galvanized strip is more suitable for slitting-based production, roll forming of small sections, reinforcement parts, and light industrial components.

For 0.2 mm thickness, Z60 and Z180 are common coating options for different service conditions. Z60 is often used where moderate protection is acceptable, while Z180 is more suitable when higher corrosion resistance is required.

2. Technical Solution

Product performance is based on:

• Continuous hot dip galvanizing with controlled zinc coating mass
• Zinc layer providing barrier protection and sacrificial protection
• Narrow-width strip supply for efficient downstream slitting and profiling
• Passivated or oiled surface for temporary storage protection
• Regular or big spangle surface for standard galvanized strip appearance

In strip processing, width control and surface stability are important because the material is often used in continuous fabrication lines. Coating mass, strip width, and surface condition directly affect later punching, bending, and forming performance.

• Visible galvanized strip parts → select regular or big spangle according to appearance preference

8. FAQ

Q1: What is the difference between galvanized strip and galvanized coil?
Galvanized strip is supplied in narrower widths and is typically used for slit-strip processing, small profiles, and narrow fabricated parts.

Q2: Is 0.2 mm galvanized strip suitable for roll forming?
Yes, it is commonly used for lightweight profiles and narrow formed components, depending on section design and processing method.

Q3: What is the difference between Z60 and Z180?
Z180 has a higher coating mass and is generally selected when stronger corrosion resistance is required.

Q4: Can this material be supplied in custom strip widths?
Yes, galvanized steel strip can be produced within the specified width range according to downstream processing requirements.

Q5: Which surface treatment is suitable before storage and transport?
Passivated or oiled surface is commonly selected to reduce oxidation risk during storage and shipment.
