Signage grade corriboard, also known as corflute corrugated plastic, is a versatile and durable material that is commonly used for a variety of different types of signs. One of the most popular options for signage is the 5mm 900gsm 2440mm x 1220mm sheets, which are known for their high quality and durability.

One of the key features of these sheets is their thickness. At 5mm, they are thick enough to provide a solid, stable base for your signs, while still being lightweight and easy to handle. This makes them ideal for both indoor and outdoor use, as they can withstand varying weather conditions and can be easily transported to different locations.

The 900gsm weight also adds to the durability of the sheets, as it gives them a sturdy and stable feel. The sheets are made from high-density polyethylene (HDPE), which is a strong and durable plastic that can resist damage from UV rays, water, and other environmental factors. This makes the signs resistant to fading and discoloration, which can be especially important for outdoor signs.

The corrugated design of the sheets also makes them easy to work with, as they can be cut and shaped to fit any design or layout. The standard size of 2440mm x 1220mm is also widely available and easy to find, making it convenient for print shops to cut and print on with ease.

Another key feature of these sheets is that they are corona treated. Corona treatment is a process that uses an electric discharge to modify the surface of the plastic, making it more receptive to printing inks. This improves the quality of the printed image and ensures that the colours are bright and vivid, even after prolonged exposure to the elements.

Overall, signage grade corriboard 5mm 900gsm 2440mm x 1220mm sheets with corona treatment are an excellent choice for anyone in need of high-quality, durable signs. They are versatile, easy to work with, and provide a strong and stable base for any design, making them a popular choice among print shops and sign makers.
