Moreover, protective paints and coatings are integral to maintaining the longevity, safety, and functionality of surfaces and structures in diverse commercial and industrial applications. The correct application of paints and protective coatings ensures their durability, maximizing effectiveness and minimizing maintenance costs over time.

Painting brackets in construction may seem minor or not a priority at first glance, depending on factors such as budget, timeline, client preferences, and the overall design aesthetic of the project. However, brackets play a crucial role in construction by providing structural support, alignment, stability, versatility, flexibility in design, and ease of installation. Their importance cannot be overstated in ensuring the commercial buildings’ durability, safety, and functionality in built environments. These are why painting brackets should be a significant part of any commercial or industrial painting project.

Recent bracket painting project done 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.

The painting process

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

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

The project took two days to complete; the first day was for prepping and priming, and the second was for applying the finishing coat.

Challenges faced

Throughout the project, the crew encountered weather problems due to frequent rain this time of the year. For this reason, the team had a 4-day window (one day prior, two days for application, and one day following) to complete the work properly. Luckily, the weather cooperated, the team had excellent primer and finish paint adhesion, and the custom color match turned out perfectly.

The role of brackets in commercial construction

What are brackets, and what types are used in commercial construction?

Brackets are structural elements that support beams, joists, or other components. Brackets come in varying shapes, sizes, and materials and serve different purposes depending on the specific application. Here are some common types of brackets used in construction:

• L-shaped brackets are the most common type of brackets. They feature a right-angle shape resembling the letter “L.” L-shaped brackets are often used for supporting shelves, countertops, beams, or other horizontal members.
• Corner brackets reinforce the corners of structures, such as framing in buildings or furniture. They are typically L-shaped and provide additional strength and stability to the joint.
• Angle brackets are similar to L-shaped brackets but are often longer and more versatile. They can support beams, trusses, or other structural elements at various angles.
• Custom brackets are tailored for specific structural needs or architectural aesthetics.

Examples of bracket application in structures

Brackets are crucial in structures, especially in construction and architectural design. Here are some examples of how brackets are applied in structural contexts:

• Supporting overhangs – Brackets evenly distribute the weight of construction overhangs to the main structure, ensuring stability.
• Beam and joist reinforcement – In wooden frame construction, brackets reinforce connections between beams and joists, providing additional support and resistance against shear and bending forces.
• Architectural aesthetics – Decorative brackets provide architectural detail and interest to buildings, often reflecting the style or period of the construction.
• Seismic retrofitting – In earthquake-prone areas, brackets are used in seismic retrofitting to strengthen existing buildings. They help secure the structure to the foundation and reinforce connections between different structural elements to improve earthquake resilience.
• Connecting trusses and girders – In larger structures, brackets connect trusses to girders or columns. These connections are vital for the structure’s stability, distributing loads evenly across the framework.
• Door and window installation – Specialized brackets are used to install windows and doors to ensure they are securely attached to the building’s framework, providing a reliable anchor point that can withstand operational stresses and environmental factors.

The importance of brackets in ensuring structural integrity

Brackets are critical in ensuring a building’s structural integrity in several ways:

• Load distribution – Brackets help distribute loads evenly across the structure. By connecting different structural elements, brackets ensure that weight and forces are spread out, reducing the risk of localized stress points that could lead to failure.
• Reinforcement – Brackets reinforce joints and connections between different parts of a structure, such as beams, columns, and walls. This reinforcement is vital in areas of high stress or dynamic forces, like wind or seismic activity.
• Stability and support – Brackets provide stability and support to various building components, ensuring that elements like balconies, staircases, and cantilevers are securely attached and supported.
• Flexibility – In earthquake-prone areas, brackets can provide the flexibility required for buildings, allowing them to move without causing significant damage. This flexibility is crucial for the longevity and safety of structures in seismically active regions.
• Aesthetic integration – Other than their structural benefits, brackets can also be designed to complement the architectural aesthetics of a building, providing functional support while enhancing visual appeal.

The purpose of painting brackets

Painting or providing protective coatings to construction brackets serves several important purposes, both practical and aesthetic:

Corrosion resistance

One of the primary reasons for applying protective coatings or paint to construction brackets is to prevent or slow down corrosion. Many construction brackets are made of metal that can oxidize and corrode over time when exposed to moisture, oxygen, and other environmental factors. Protective coatings form a barrier that minimizes the metal’s exposure to these elements, thereby extending the lifespan of the brackets.

Durability

A protective coating can significantly enhance the durability of construction brackets. By protecting against rust, corrosion, and wear, coatings ensure that the brackets maintain structural integrity over time. It is especially crucial in environments prone to harsh weather conditions or where the brackets are exposed to chemicals that could degrade the metal.

Aesthetic appeal

While practicality is often a concern, the aesthetic appeal of construction brackets cannot be overlooked, especially in visible areas. Coatings and paint can be used to improve the appearance of brackets, making them blend in or complement the surrounding structures. It is particularly relevant in architectural and public infrastructure projects where visual consistency and appeal are top priorities.

Chemical protection

Construction brackets may be exposed to various chemicals, depending on their location and application. Protective coatings can provide a layer of chemical resistance, protecting the metal from potentially harmful interactions with acids, alkalis, solvents, and other industrial chemicals.

UV protection

UV protection is another consideration for brackets used in outdoor applications. Continuous exposure to ultraviolet light from the sun can weaken and degrade materials over time. Certain coatings include UV inhibitors to protect against this form of degradation, extending the lifespan of the brackets.

Safety and identification

Coatings can also be used for safety purposes, such as color-coding brackets to signify different functions or load capacities, which can assist in safely and correctly using these components on construction sites.

Cost-effectiveness

In the long run, applying protective coatings or paint to construction brackets is cost-effective. It reduces the need for frequent replacements or repairs due to corrosion or wear, saving money and reducing maintenance efforts over the lifetime of a structure.

Applying protective coatings or paint on construction brackets is critical in ensuring their longevity, functionality, and aesthetic integration into construction projects.
