Polyurethane Architectural Metal Finishing

Powerful and Durable Coating for Metal Surfaces

Polyurethane is a substance that is, in most cases, a thermosetting polymer that will not melt when heated. It is commonly used as an architectural metal finishing. Applied in a thin film, once it cures, it forms a powerful and durable barrier for the underlying subsurface. Polyurethane coatings offer great flexibility in terms of finishes, including high-gloss, semi-gloss, pearl, satin, matte, and eggshell options. It is frequently used as a topcoat over epoxy priming in light of the fact that it supplies the UV resistance that epoxy lacks.

What Are The Benefits of Polyurethane Architectural Metal Finishing?

In addition to blocking UV rays, polyurethane metal finishings also offer a number of different benefits, including:

  • Weather resistance
  • Corrosion resistance
  • Abrasion resistance
  • Chemical resistance
  • Oil resistance
  • Acid and alkali resistance

Is Polyurethane Architectural Metal Durable?

Furthermore, polyurethane metal finishing is able to stand up to high-pressure washdowns, making it relatively easy to clean and maintain. Polyurethane is valued for being a hard and non-toxic metallic finish that is also relatively low in terms of volatile organic compound (VOC) release. 

It is commonly employed for protection of structural steel and is used in industrial settings for railings, architectural coating, and for equipment. It may also be used for institutional finishes, military specs and building components, depending on the nature of the project.

How Long Does Polyurethane Coating Last?

The longevity of a polyurethane coating depends on various factors such as the type of polyurethane used, the application process, environmental conditions, and the level of wear and tear. On average, polyurethane coatings can last anywhere from 5 to 10 years or more. 

Here are some key factors that influence the typical lifespan of a polyurethane coating:

  • Quality of Material: Higher-quality polyurethane coatings tend to have better durability and longevity.
  • Application Process: Proper application techniques, including surface preparation and even coating application, contribute to the coating's lifespan.
  • Type of Polyurethane: There are different formulations of polyurethane coatings, such as water-based, solvent-based, and UV-cured. Each type may have varying durability.
  • Environmental Conditions: Exposure to sunlight (UV radiation), temperature fluctuations, humidity, and chemical exposure can impact the coating's lifespan.
  • Wear and Tear: The level of foot traffic, abrasion, impact, or other mechanical stresses the coated surface experiences affects how long the coating will last.
  • Maintenance: Regular cleaning and maintenance can extend the life of the polyurethane coating.
  • Proper Care: Avoiding harsh cleaning agents, abrasive materials, and sharp objects on the coated surface can prevent premature degradation.
  • Sealing and Repairs: Periodic resealing and addressing minor damages can help prolong the life of the coating.

It's important to note that while polyurethane coatings offer durability, they will eventually wear down over time. Regular inspection and maintenance are essential to ensure that the coating continues to provide optimal protection and aesthetics for the intended surface.

    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.
