In Malaysia’s tropical climate — where high temperatures, intense UV rays, and frequent rainfall are part of daily life — traditional wooden or metal signboards often rust, fade, or warp over time, leading to high maintenance costs and a shorter lifespan.
That’s why ACP (Aluminium Composite Panel) has become the most popular outdoor signboard material in Malaysia, especially in major cities like Kuala Lumpur (KL), Selangor, Penang, and Johor Bahru (JB).
Known for being lightweight, UV-resistant, waterproof, rustproof, and low-maintenance, ACP signboards deliver long-term durability and a sleek, modern appearance that enhances brand image while reducing upkeep costs.
Today, more than 90% of outdoor signboards in Malaysia use ACP panels as their main structural and surface material. From LED lightboxes and shopfront façades to shopping mall exteriors, pylon tower signs, and high-rise building claddings, ACP remains the preferred choice for businesses that value brand consistency, weather resistance, and long-term ROI.
ACP (Aluminium Composite Panel) is a high-performance, three-layer composite material widely used in modern signboard and architectural design across Malaysia.
It consists of:
💡 This shield-like layered structure gives ACP panels their unique advantages — they are lightweight yet strong, UV-resistant, waterproof, and anti-oxidative, making them perfectly suited for Malaysia’s hot, humid, and tropical climate.
Made from two aluminium sheets and a polyethylene (PE) or fire-resistant (FR) core, ACP Aluminium Composite Panels combine lightweight strength, weather resistance, fire safety, modern aesthetics, and low maintenance — making them the most widely used outdoor signboard material in Malaysia.
Their innovative three-layer design provides long-term durability, ensuring your outdoor signage stays vibrant, rust-free, and stable even under Malaysia’s harsh tropical weather.
ACP (Aluminium Composite Panel) is about 30% lighter than traditional steel sheets, yet equally durable and rigid.
This lightweight strength reduces the structural load and makes installation safer and faster, especially for large-scale outdoor signage projects.
✅ Ideal for Pylon Signs, Lightboxes, and Building Wall Facades.
Each ACP panel is coated with PVDF (Polyvinylidene Fluoride) or Nano Coating, designed to withstand intense UV rays, acid rain, and sea air corrosion common in Malaysia’s tropical environment.
Whether installed in Kuala Lumpur (KL), Penang, or Johor Bahru (JB) — all known for their hot and humid climates — ACP panels retain their colour and finish for 8–10 years without fading or rusting.
✅ UV Resistant ｜ ✅ Waterproof & Anti-Corrosion ｜ ✅ Long-Lasting Weather Durability
One of the biggest advantages of ACP Aluminium Composite Panels is their smooth, seamless surface, which creates a clean and professional finish.
They integrate perfectly with modern signboard techniques such as:
✨ 3D LED Lettering
✨ UV Printing or Laser-Cut Logos
✨ Acrylic Front Panels
ACP Aluminium Composite Panels are highly versatile and easy to work with — they can be cut, bent, punched, or jointed into almost any shape, making them ideal for creative signboard designs.
Each panel also comes with an anti-dust and stain-resistant surface coating, meaning you only need to wipe it occasionally to keep your signage looking bright and new.
💡 Perfect for shopping mall façades, factory entrances, and retail chain storefronts that require long-term, low-maintenance signage solutions in Malaysia’s humid climate.
For added safety, ACP panels are available with FR (Fire-Resistant) Core, compliant with ASTM E84 Class B1/B2 standards.
This fire-retardant layer helps slow down flame spread and ensures your signboard remains structurally safe — making it suitable for shopping complexes, petrol stations, and industrial buildings where safety standards are crucial.
「ACP Signboard = Weatherproof + Lightweight + Safe + Stylish + Low Maintenance」
With its outstanding UV resistance, waterproof durability, and fire-safety performance, ACP Aluminium Composite Panel has become the go-to material for outdoor signboards in Malaysia.
Whether your business is based in Kuala Lumpur (KL), Penang, Johor Bahru (JB), or Melaka, ACP ensures your signage remains vibrant, long-lasting, and fade-resistant — even under Malaysia’s intense sun and humid weather.

🚫 Using ACP Panels That Are Too Thin (3mm) → Easily warps and forms surface waves.
🚫 Using Non-Rust-Proof Screws → Rust stains appear after rain.
🚫 No Waterproof Edge Sealing → Rainwater seeps in, causing swelling or delamination.
🚫 Using Low-Quality Power Supply → LED lights burn out easily.
Under Malaysia’s hot, humid, and rainy climate, ACP aluminium composite panels offer outstanding durability — resisting heat, rain, and UV damage while keeping your signage looking sharp and professional.
Compared to PVC or vinyl stickers, ACP signboards deliver a much higher return on investment (ROI) thanks to their long lifespan and minimal maintenance.
