Common materials for signage include metal, acrylic, PVC, wood, stone, and electronic materials. Different materials are suitable for various indoor and outdoor scenarios, each with its own performance advantages and visual characteristics.
Metal Materials
Metal signs are known for their strong texture and high durability, and are widely used in outdoor or high-end locations.
Stainless Steel: Corrosion-resistant and oxidation-resistant, suitable for building signage, corporate image walls, restroom signs, etc. It can be finished with brushed, etched, or mirrored surfaces to enhance its texture.
Aluminum Alloy: Lightweight and weather-resistant, it is the mainstream choice in the signage industry. 3-series rust-resistant aluminum (such as 3003) is suitable for general outdoor environments, while 5-series magnesium-aluminum alloys (such as 5052) are more resistant to seawater corrosion and suitable for coastal areas.
Cold-Rolled Steel Sheet
Highly malleable and easy to bend and weld, often used for industrial-style slogans or large billboards, but requires proper paint protection to prevent rust.
Copper
Commonly used in high-end custom signage, such as company nameplates and museum information signs. An antique finish gives it a vintage aesthetic.
Acrylic (Plastic Crystal)
Also known as "plastic crystal," it has good light transmission and rich colors, suitable for indoor illuminated lettering, employee name tags, and restaurant table number signs.
Three-dimensional effects can be achieved through engraving, vacuum forming, and UV printing. It has a more visually impactful effect at night when combined with LED lighting.
PVC
Lightweight and low-cost, available in frosted and transparent finishes. It comes with self-adhesive and is commonly used for temporary signage, metal tags, and clothing hang tags.
Although its impact resistance is relatively poor, diverse graphic presentations can be achieved through screen printing and heat transfer printing.
Wood and Stone
Wood: Such as walnut and burgundy, it gives a natural and welcoming feel and is often used in garden and scenic area wayfinding systems. However, it needs to be protected against moisture and cracking.
Stone materials, such as granite and marble, have a long lifespan and a dignified style, making them suitable for cultural spaces such as parks and memorial halls. However, they are heavy and difficult to process.
