Why You Should Request Physical Paint Samples Before Purchase

Posted by Casey Shearns on Tue, Jun 08, 2021 @ 02:43 PM

Online color cards make it easy for a quick preview of the colors offered, but they can create a discrepancy between the color on the monitor and the appearance of the actual paint.

Computer monitors are all color calibrated differently. This makes every shade shown on the color card appear slightly different on different monitors, and different in person. The color card should only be used as a general guide to the types of colors offered. Physical color cards should be used for making a final decision to ensure that your final coating looks the way you intended.  

However, using a digital color card on a computer monitor can be useful for making a selection that doesn’t have to match an existing color or be very specific. If you need a general color and are not concerned about slight variation, you may choose to select a color using the digital card only.

Here are a few physical examples compared to the way a color might appear on your computer screen:

Can You Powder Coat Hot-Dip Galvanizing?

Posted by Casey Shearns on Mon, May 17, 2021 @ 03:49 PM



Can you Powder Coat Galvanized Steel?

Powder coatings can be applied over hot-dip galvanizing and are a great way to add a desired look or color to material for your project. There are a number of benefits to using duplex systems on your steel, including both corrosion protection and aesthetic benefits. Read on to learn more about powder coatings over hot-dip galvanized steel.

The Powder Coating Process

First, the material is hot-dip galvanized in our zinc bath. The surface is then prepared by removing any bumps or drips from the steel to ensure smooth application. Next, the surface of the material will be profiled with blasting to create good surface adhesion for the powder coating. The steel is then “out-gassed” around 500 degrees fahrenheit to further provide a smooth and adhesive surface. For maximum adhesion, the material is then primed and baked.  

Powder is typically sprayed on to the material soon after after out-gasing. After application, the material is placed in the curing oven where the powder primer will bond to the galvanized coating.

Benefits of Powder Coatings 

Powder coating adds an extra layer of corrosion and weathering protection to your steel (known as a duplex system). The duplex system also allows for less maintenance over time, saving money on the project over time. Additionally, power coatings come in a number of different colors and finishes, allowing you to customize steel for your specific needs.
