What Are ACP Sheets?

ACP stands for Aluminum Composite Panel. An ACP sheet is made by combining two thin aluminum sheets with a plastic core in the middle. This combination creates a strong but lightweight panel.

Because of this structure, ACP sheets are:

• Strong
• Flat and smooth
• Weather resistant
• Easy to cut and shape

These features make ACP sheets perfect for sign boards, shop fronts, and outdoor branding.

Why ACP Sheets Are Used for Sign Boards

ACP sheets are widely used in signage because they solve many problems that other materials cannot.

Here are the main reasons why ACP sheets are ideal for sign boards:

1. Strong but Lightweight

ACP sheets look heavy but are very light. This makes installation easy and safe, especially for large sign boards.

2. Weather Resistant

They can handle heat, rain, dust, and sunlight. This makes them perfect for outdoor signage.

3. Clean and Professional Look

ACP sheets have a smooth surface. Printing, vinyl pasting, and cutting look very neat on them.

4. Long Life

ACP sign boards can last for many years without bending, cracking, or fading.

5. Easy to Customize

They can be cut, bent, folded, and shaped into different designs and letters.

How ACP Sheets Are Made

An ACP sheet has three layers:

1. Top Aluminum Sheet
2. Plastic Core (usually polyethylene)
3. Bottom Aluminum Sheet

These layers are pressed together using heat and strong adhesive. The aluminum surface is then coated with special paint to protect it from weather and scratches.

This structure gives the ACP panel its strength and flexibility.

Common Thickness of ACP Sheets for Sign Boards

ACP sheets come in different thickness options. Choosing the right thickness depends on the type of sign board.

Popular ACP Thickness Sizes:

For most sign boards, a 3mm or 4mm ACP panel sheet is enough.
