Unistrut Finishes: Choose the Right Type for Your Application
Unistrut is popular for its durability and versatility, but it also boasts other benefits. One of the great things about Unistrut is the wide range of finishes that are available. The finishes can help to protect your structure against corrosion and other types of damage. In this blog post, we'll explore the different types of Unistrut finishes and help you to choose the right one for your application.
List Of Unistrut Finishes
Plain (PL)
If you don't need any special protection for your Unistrut, you can opt for the PL finish. This is a simple, uncoated finish that is suitable for applications where corrosion is not a concern. Plain finish is typically the finish of choice for OEM's (original equipment manufacturers) as it’s weldable. Once welded it can be painted or powder coated to a desired color, to inhibit rust or to match the needs of the application. It's a great choice for indoor use, where the Unistrut will be protected from the elements. However, if you're working in an environment where corrosion is likely, you'll need one of the other Unistrut finishes.
Unistrut Perma-Green III
Unistrut Perma-Green III is a powder-coated finish that provides superior protection against corrosion and other types of damage. It's an ideal choice for outdoor applications, as it can withstand exposure to rain, snow, and sunlight without fading or peeling. This finish is also resistant to chemicals, making it a great choice for industrial environments.
Electroplated Zinc (EG)
The EG finish is created by electroplating the Unistrut with a layer of zinc, which provides excellent protection against corrosion. It's a great choice for indoor use, as it's relatively inexpensive and easy to install. However, it's not as durable as some of the other Unistrut finishes and may not be suitable for outdoor use or harsher environments.
Pre-Galvanized Zinc (PG)
Pre-galvanized zinc is similar to electroplated zinc, but the zinc coating is applied before the Unistrut is formed into its final shape. This means that the entire surface of the Unistrut is coated, providing better protection against corrosion. PG is a good choice for indoor use and is often used in applications where appearance is important, such as retail environments.
Hot Dipped Galvanized (HG)
Hot dipped galvanized Unistrut is created by dipping the Unistrut into a bath of molten zinc, which forms a thicker, more durable layer of zinc coating. This makes HG ideal for outdoor use and applications where the Unistrut will be exposed to harsh environments. It's often used in marine and coastal environments or for infrastructure projects like bridges and highways.
Unistrut Defender (DF)
The Unistrut Defender finish is a patented solution that provides the ultimate protection against corrosion and other types of damage. It's a multi-layered coating that includes a zinc layer, an epoxy layer, and a UV-resistant topcoat. Defender is suitable for use in all kinds of environments and is often used in industrial applications like chemical plants and power stations.
Choosing the right type of Unistrut finish is essential for ensuring the longevity and durability of your construction project. Whether you need basic protection against corrosion or want to ensure that your Unistrut can stand up to harsh conditions, there's a Unistrut finish that's right for you. By understanding the different options available, you can select the right finish for your specific application and enjoy peace of mind knowing that your Unistrut will last for years to come.
