1.2mm Prepainted Color Steel Coil with 180–320MPa Yield Strength and 10–25μm Top Coating for Fencing Panels

1. Product Overview

Prepainted color steel coil is commonly used for fence panels, boundary sheets, exterior cladding, and other formed sheet products that require both surface finish and basic corrosion protection. Compared with unpainted metal sheet, the painted surface provides color consistency and a cleaner finished appearance for visible applications.

For fencing use, thickness, yield strength, paint system, and coating thickness are the main practical factors. A thicker sheet such as 1.2 mm is generally used where higher panel rigidity is required, while the top paint layer affects surface appearance and weather exposure performance.

2. Technical Solution

Product performance is based on:

• A coated steel substrate combined with an organic paint layer
• Top and back paint structure selected according to end use
• Different coating systems for different exposure conditions
• Yield strength and elongation matched to roll forming and bending
• Surface treatment selected for storage and downstream handling control

For fencing panels and exterior profiles, the balance between formability and rigidity is important. Yield strength of 180–320 MPa supports general forming, while elongation of 16–30% helps reduce cracking risk during bending and profiling.

7. How to Choose

• General fencing and mild outdoor use → PE is commonly selected
• Higher weather exposure → SMP or HDP is often considered
• Projects requiring stronger long-term exterior stability → PVDF can be considered
• Thicker and more rigid fence panels → 0.8–1.2 mm is commonly used
• Higher appearance requirement → choose suitable top coating thickness such as 20–25 μm

8. FAQ

Q1: Is 1.2 mm suitable for fencing panels?
Yes. 1.2 mm is commonly used when higher rigidity and stronger panel feel are required in fence and boundary applications.

Q2: What is the difference between PE, SMP, HDP, and PVDF?
They are different paint systems. Selection usually depends on the required balance between cost, appearance retention, and weather exposure resistance.

Q3: Does higher top paint thickness always mean better performance?
A thicker top coat generally improves surface coverage, but the final result also depends on coating system, forming method, and service environment.

Q4: Can this coil be roll formed into fence profiles?
Yes. It can be used for cut-to-length sheets, slitting, and roll forming for fence panels and related sections.

Q5: What coil size is suitable for standard processing equipment?
Coil IDs of 508 mm and 610 mm and coil weights of 3–8 MT are commonly used in industrial decoiling and roll forming lines.
