Everything You Need to Know About ACP Panels in 2025

An acp panel is also called an aluminum composite panel. It has a sandwich-like structure. Makers stick two thin aluminum sheets to a middle core. The core is not made of aluminum. It can be polyethylene or a fire-resistant mineral. This special design makes the panel light, strong, and bendable. In 2025, more builders use acp panels. This is because building rules are stricter. People also want more design choices and care about the environment. New materials now include eco-friendly resins. There are also better fire-retardant cores and self-cleaning coatings. Architects and builders worry most about fire safety. They also care about following rules, panel quality, and needing skilled workers to install them.

Key Takeaways

  • ACP panels are light, strong, and bend easily. This makes them simple to put up. They are great for new building styles. Fire safety is very important. Fire-retardant cores with minerals help keep people safe. They also follow strict building rules. Good coatings like PVDF protect the panels from weather. They stop fading and damage. This helps the panels last 20 years or more. ACP panels work in many ways. People use them for building fronts, signs, inside walls, and ceilings. They are tough and can be used in many designs. Picking the right ACP panel means checking fire ratings, finishes, and certifications. You should also look for eco-friendly features to match your project.

ACP Panel Composition

Aluminum Layers

Aluminum composite panels have two thin aluminum sheets outside. These sheets make the panel strong and protect the core. The thickness of the sheets changes for different uses. Thicker aluminum is used for outside walls or tall buildings. This helps the panel stand up to wind and last longer. Thinner aluminum is used for signs or inside spaces.

High-grade aluminum, like the 3333 or 5333 series, stops rust and makes the panel stronger. These features help the panel last longer in bad weather. The grade and thickness of aluminum change how stiff and tough the panel is. Builders pick special alloys for curtain walls to meet safety rules.

Note: Using thicker aluminum and better alloys makes acp panels safer for tall buildings.

Core Materials

The core is between the two aluminum sheets. It is important for fire safety, weight, and insulation. Makers pick different core materials for different projects.

Core Material Type

Description

Fire-Retardant Properties

Polyethylene (PE) Core

Lightweight, affordable, commonly used for signage and interior applications

Highly flammable, low fire resistance, suitable where fire rating is less critical

Fire Retardant (FR) Core

Contains additives like magnesium or aluminum hydroxide to reduce flammability and smoke emission

Improved fire resistance, meets stricter fire safety requirements, used in hospitals and high-rise buildings

Mineral Core

Composed of non-combustible minerals such as magnesium oxide or aluminum hydroxide

Superior fire resistance and thermal insulation, ideal for high-fire-rated applications like airports and tunnels

Aluminum Honeycomb Core

Hexagonal aluminum foil cells bonded together, includes non-combustible minerals

High fire rating and mechanical strength, suitable for marine, aerospace, and transportation industries

Polystyrene (PS) Core

Expanded polystyrene foam core providing insulation

Less focused on fire resistance, mainly used for insulation purposes like sound barriers and cold rooms

New fire-retardant cores use more minerals and less polyethylene. This makes them safer from fire. Some panels now use solid aluminum or honeycomb cores for even better fire safety. Fire-retardant aluminum composite panels are popular in hospitals, hotels, and metro stations. They stop fire from spreading and stand up to bad weather.

Coating and Finish

The coating on an aluminum composite panel keeps it safe from weather and looking nice. Makers use different coatings for different places.

Weather Resistance

Typical Use

Shelf Life

Fade Resistance

Cost

PE (Polyethylene)

Average; suitable for interior or short-term outdoor use; easily eroded by UV and rain

Interior decoration or short-term outdoor

5-8 years

Light colors fade in 5-8 years; dark colors fade faster

Lower cost; cost-effective for limited budgets

PVDF (Polyvinylidene Fluoride)

Superior anti-corrosion and anti-fading; ideal for long-term outdoor exposure

Long-term outdoor use

15-20 years (less near sea or extreme UV)

Light colors last 15-20 years; dark colors fade gradually

Higher cost; more cost-effective long-term

The coil coating process has steps like cleaning, priming, baking, and adding a top layer. This makes the panel strong against weather, rust, sun, and water. PVDF coatings last longer and keep their color better than PE coatings. That is why people use them outside.

Taking care of the panels and using the right finish keeps them strong and looking good for years. Good coatings mean less work to keep them up and make them last longer in all kinds of weather.
