Powder Coating

An Environmentally Friendly Option

Powder coating is a popular technique for architectural metal finishing—highly valued because it creates a thick and durable layer of protection for metal surfaces. It works by applying an electrostatic charge to the surface of the metal item, then blasting it with small particles of a thermoplastic or thermoset polymer. Thanks to the electric charge of the metal, the dry powder material is attracted to the surface, forming a powerful bond. 

Our team at Certified Enameling, Inc. then bakes the item in one of our ovens to cure the surface, in order to make it as strong as possible. The result is a metal finishing that is among the most durable and scratch resistant available.

Benefits of Powder Coating

Powder coating offers benefits that other metal finishes like Kynar®, liquid paint, and anodizing don’t. As a full-service coating company, we can help you determine if powder coating is the best choice for your architectural or commercial project.

Four benefits of powder coating:

  1. Nearly impervious to scratches, chipping, and other types of damage, including damage due to the elements—allowing for long-lasting and beautiful results.
  2. Outstanding gloss retention.
  3. Highly customizable, with a wide range of colors, finishes, glosses, and textures, including the popular hammer tone finish.
  4. Can be applied to a variety of architectural materials, including: column covers, curtain walls, sheets, sun rooms, formed paneling, extrusions, ornamental metals, skylights, automatic doors, composite paneling, formed windows, vents, louvers, sunshades, and more.

Before we begin the powder coating process, we will thoroughly pretreat your metal, using either an Alodine chrome phosphate pretreatment or other cutting-edge solutions to ensure results that are beautiful, long-lasting, and highly durable.

How Long Does Powder Coating Last?

One of the reasons powder coating is becoming so popular is because of its durability and ease of application. The period of application to being completely cured only takes 30 minutes, which makes it a great option for projects with tight deadlines. Additionally, powder coating is known for its strength and can last anywhere from 15-20 years.

Is Powder Coating Only Applied On Metals?

Today, the uses for powder coating continue to grow. In addition to making metal pieces beautiful and unique, we can also apply powder coating to wood and glass products as well.

Thermoplastic VS. Thermoset Powder

When heated, a thermoplastic powder coating, which is typically thicker and more durable than thermoset powder, will become soft and liquid-like, thus eliminating the need for chemical bonding. This also makes thermoplastic powder coating reusable and reversible. Due to this, it is more expensive than thermoset powder.

Thermoset powder coating, on the other hand, forms chemical bonds once it is cured, rendering it impossible to recycle. Because of its inability to melt due to the chemical bonds, it's best suited for high heat areas.

We can discuss your project with you and help you determine whether thermoplastic or thermoset powder will work best.

    I never write letters, but today I felt compelled. Recently, I have been working on the project from hell. Nothing went right. The land had issues, the city had issues, the client couldn't make up their mind on anything, my staff was stretched thin, we were over budget, etc... I can honestly say that the ONLY thing that met and exceeded expectations was the part of the work that was done by Certified Enameling. Your staff was great, the job was done earlier than I expected, and the cost was to the penny what you quoted. Now if we can just get everybody else on par with you guys, life will be good. Thanks Glenn and Adrian. You guys are excellent!

    So far the initial reactions from our client and designer are all good! Thanks for all of your efforts in helping us make this a successful project; I know it has been an effort on everyone’s part. Thank goodness we assembled a good team of vendors to assist us with this project. So we only have a few more panels to put through the process so we will bear down a little longer.


    I want to take a moment to truly thank Glenn, Adrian, Scott and all the staff at Certified Enameling. I've been in the property development business for 30 years and I don't think I can ever remember dealing with a company that gets the job done like these guys do. The quality in which they deliver their service is truly appreciated. When they say the job is gonna be done in 2 days, they mean it, consistently. If all of my vendors provided products and services like the guys at Certified, I would never miss a deadline. I can't thank them enough!

    Hi Glenn, and the entire team at Certified Enameling. This week marks the completion of our 4,000 panel manufacturing run for this high profile project. It’s been a hectic 3 months to say the least. I just want to compliment the manner in which Certified Enameling stepped up to the plate, and did whatever was required to keep CPS, and ultimately our customer on schedule for this project. You went above and beyond the call of duty, and we sincerely appreciate your efforts. I am confident that no other firm, or team of firms in Southern California could have accomplished what we just accomplished in such a short time frame. Thank you for being such a strong business partner, and helping CPS achieve our goals.


    I've been wondering for years why when I get a metal finishing job done with another company it takes so much longer than with Certified Enameling? I'm talking double to triple the amount of time. I don't know if it's their process, their staff or their experience. The funny thing is that their work product is equal to, if not downright superior to the competition. Recently I decided, I really don't care how they do it, I'm just not going anywhere else anymore. You guys define expertise in every sense of the word and have earned my business for life. One less thing to worry about. Thanks Certified Enameling.
