3mm ACM (Aluminum Composite Material):

3mm ACM is a versatile material composed of two thin aluminum sheets bonded to a polyethylene core. Known for its durability and lightweight properties, it is commonly used in the sign industry for outdoor signage due to its weather-resistant nature.

3M IJ180 Vinyl:

The 3M IJ180 Vinyl is a high-quality, adhesive-backed vinyl designed for long-term outdoor graphics. It is known for its conformability, making it suitable for wrapping vehicles or applying to irregular surfaces, providing a seamless and professional look.

3M IJ 280Cm Vinyl:

Similar to the IJ180, the 3M IJ 280Cm Vinyl is renowned for its durability and print quality. This vinyl is designed to withstand harsh outdoor conditions, making it a popular choice for a variety of signage applications.

1/4 Acrylic:

1/4-inch acrylic is a transparent thermoplastic known for its optical clarity. Used extensively in sign shops, it provides a professional appearance for indoor signs and is often laser-cut for precision in creating intricate designs.

1/2 Acrylic:

Thicker than its 1/4-inch counterpart, 1/2-inch acrylic offers increased durability. It is a preferred material for creating more substantial indoor signs, providing a solid and substantial feel.

3/4 Acrylic:

The 3/4-inch acrylic is the thickest among the mentioned acrylic options. This thickness adds a significant level of sturdiness, making it suitable for large and heavy-duty indoor signage.


PVC (Polyvinyl Chloride) is a rigid plastic material widely used in sign making. It is durable, lightweight, and can be employed for both indoor and outdoor applications, including point-of-sale displays and directional signs.


Coroplast, also known as corrugated plastic, is a lightweight and cost-effective material. Commonly used for temporary outdoor signs, it is made of twin-wall polypropylene sheets with hollow channels, providing both durability and flexibility.


While not as durable as some other materials, paper remains a popular choice for certain applications, such as posters, flyers, and temporary signage, due to its cost-effectiveness and ease of printing.

Window Perf Vinyl is a specialized material with micro-sized holes that allow one-way visibility. Widely used for window graphics, it provides an effective way to display advertising messages while maintaining visibility from the inside.


Fabric is a versatile material used for various applications, including banners, flags, and trade show displays. Its flexibility and portability make it a popular choice for on-the-go marketing.


Aluminum is a durable and weather-resistant material commonly used for outdoor signs. It is lightweight and can be printed on directly or used as a substrate for other materials.

Reflective Vinyl:

Reflective vinyl is designed to reflect light, making it highly visible in low-light conditions. This material is frequently used for road signs, vehicle graphics, and other applications where visibility is crucial.

Stainless Steel:

Stainless steel is a durable and corrosion-resistant material often used for creating durable, high-end signs. It adds a sleek and modern aesthetic to signage, making it suitable for upscale establishments.
