What are exposed purlins?

Exposed purlins are structural elements typically found in buildings with metal roofs, such as barndominiums, carports, and other steel structures. Purlins are horizontal beams that support the roof's load and are usually placed under the roof sheeting. When these purlins are visible from underneath the roof—rather than being concealed by a ceiling or insulation—they are referred to as "exposed purlins."

Why are they important?

Exposed purlins play a crucial role in the overall stability of a structure. They help distribute the weight of the roof and provide resistance against heavy winds, making them especially vital in areas prone to extreme weather, like coastal regions. In addition, the visibility of these purlins makes them easier to inspect for signs of wear, corrosion, or damage, ensuring that any necessary maintenance can be performed promptly.

Protecting Exposed Purlins from Corrosion

Since exposed purlins are not covered, they are more susceptible to environmental factors like humidity, salt, and brine, which can accelerate corrosion. Regular cleanings and applying protective coatings, is essential to prolong the lifespan of exposed purlins and maintain the integrity of your building.

By understanding the significance of exposed purlins and taking steps to protect them, you can enhance the durability of your property.

What Can Beachfront Bright Do To Help You?

Beachfront Bright offers unique services for our costal area. An “Assessment & Intervention” service will identify any damage to exposed purlins and remove any existing corrosion. Then apply a substance to stop the corrosion to prevent it from furthering under the protective paint coating that is applied last.

Monthly Brine Removal Cleaning - Schedule Today!

With Beachfront Bright’s monthly brine removal service, you can set it and forget it, knowing your property is protected from harmful salt buildup. We'll take care of the rest.

Monthly brine removal is crucial for maintaining the longevity and structural integrity of exposed metal purlins, especially in coastal environments where salt exposure is high. Here’s why:

Slows Corrosion: Brine, a mixture of salt and water, accelerates the corrosion process on metal surfaces. Regular monthly removal of brine deposits helps prevent rust and other forms of corrosion, protecting the purlins from long-term damage.
Protects Investment: Whether it’s a barndominium, carport, or other metal structure, your property is a significant investment. Monthly brine removal helps protect that investment by slowing the harsh effects of the coastal environment.
