Coroplast versus aluminum construction signs

When choosing the best material for your next construction project, coroplast and aluminum are two popular options that come with unique advantages. Knowing the differences between coroplast and aluminum signs can help in making a better decision that will suit the budget and duration of the construction project.

Coroplast

Let’s start by looking at coroplast – the trademarked brand name of corrugated plastic sheets in North America. Made from three layers of polypropylene plastic substrate, coroplast is basically plastic cardboard. The material is a great option for temporary outdoor and indoor signage and a safe, yet budget-friendly alternative for construction projects.

Coroplast is ideal for construction signage as it is sturdy, yet extremely lightweight and resistant to rain, snow and sunshine. Its plastic structure makes it durable and it represents an affordable alternative to other signage materials. For construction projects, coroplast signs represent a safe option, as the material is lightweight, and the risk of harming workers or pedestrians is considerably minimized. On the other hand, coroplast signs can be easily bent and damaged if they are hit by construction vehicles or equipment.

Coroplast is also known for being inexpensive to print on, while the colours pay-off is vibrant and bold.  Typically, branded vinyl graphics can be applied directly to the sign in both reflective and non-reflective options, depending on your needs. It’s important to keep in mind that coroplast is not meant for permanent display. Although it is highly resistant to extreme weather, it may need replacement every 3-6 months approximately depending on exposure. When it comes to display, coroplast signs are versatile and can easily be attached to fencing using grommets.

In addition to being durable and inexpensive, coroplast signs are also easily maintained. The signs can be simply wiped down and stored at room temperature. When storing coroplast signs, it is best to avoid extreme heat which can melt the material, as well as stacking under heavy objects to prevent bending and damage. Coroplast signs are also easy to transport as they are lightweight, and they can easily be stacked on top of each other and transported from site to site.

Aluminum

On the other hand, aluminum signs are reliable, strong, and extremely durable. Compared to coroplast, they are typically used outdoors for long-term construction projects. Aluminum signs are usually made of two sheets of aluminum joined by polyethylene.

Aluminum signs are known to be very long lasting in all weather conditions. Unlike coroplast, they only require maintenance or replacement every 3 years approximately. Aluminum signs give a professional and permanent look, and just like coroplast signs they can be attached directly to fencing using grommets. Aluminum signs can be printed in full colour and reflective options are available for enhanced nighttime safety and visibility. Typically, vinyl graphics are applied directly to the surface of the panel, resulting in bold colour pay-off.

In terms of maintenance, aluminum signs can be stacked and stored for a very long time without any significant rusting. The aluminum may scratch or bend at high impact shocks, so caution must be exercised when handling vehicles or equipment.
