How Painting Brackets Can Affect Commercial Construction


In commercial construction and maintenance, brackets are structural support elements that help distribute loads and reinforce connections between components such as beams, joists, or posts. They play a crucial role in enhancing the stability and strength of a structure by providing additional support at critical joints or intersections. Brackets come in various shapes and sizes, tailored to specific construction needs, and are typically made of metal or wood. 

The perceived insignificance of painting metal brackets often stems from a few factors. In the hierarchy of construction tasks, painting brackets may be considered minor or low-priority compared to other critical tasks such as erecting structural elements, installing utilities, or finishing interior spaces. 

Regarding aesthetic significance, some stakeholders may underestimate the visual impact of painted brackets on the building’s overall appearance. Since brackets are often small and inconspicuous, their aesthetic contribution to the building’s exterior may be undervalued. As a result, painting brackets might be overlooked or deferred until the later stages of the project.

But despite these perceptions, painting brackets can play a crucial role in the longevity, durability, and overall aesthetic appeal of a building. Properly painted brackets can enhance the building’s appearance, protect metal surfaces from corrosion and weathering, and contribute to a cohesive design aesthetic. Therefore, while painting brackets may seem insignificant in the grand scheme of construction, attention to such details can have a meaningful impact on the quality and longevity of the finished structure.

Bracket Painting Project by Custom Painting, Inc.

Custom Painting, Inc. recently finished a bracket painting project in Milpitas, CA. In this project, we painted a total of 76 horizontal brackets. We are used to this type of project as we do similar work a few times a year, making us a reliable company for this paint job.

The painting process

Our crew first primed the brackets using Sherwin-Williams Macropoxy 646. It is a high-solid, high-build, and fast-drying polyamide epoxy designed to protect steel in industrial environments. 

After priming, the team used the Sherwin-Williams Pro Industrial DTM Acrylic as the finishing coat to match the adjacent material rails to which the brackets were welded. Sherwin-Williams Pro Industrial DTM Acrylic is a water-based and corrosion-resistant acrylic coating formulated for interior and exterior applications, 

The project took two days to complete. Our crew prepped and primed the surface on the first day and applied the finishing coat on the second.

Challenges faced

The weather was the only problem our crew encountered throughout the project due to frequent rain this time of the year. Because of this, they had a 4-day window (one day prior, two days for application, and one day following) to complete the work properly. Luckily, the weather was cooperative. The team had excellent primer and finish paint adhesion, and the custom color match was perfect.

The role of brackets in commercial construction
