Protective Coatings and Paint Finishes Advantages Cape Town

Steel is one of the most commonly used metals in overhead cranes and material handling systems. That’s because metals like steel are strong, cost effective, and easy to manipulate. However, steel is also prone to rust in almost any environment, especially when used for caustic applications or if exposed to harsh conditions.

To protect your crane system from rust and corrosion, most manufacturers provide options for protective coatings and paint finishes. Knowing which protective coating will best suit your operation is important to extend the lifetime of your new system. Here, we will explore several protective coating and paint finish options for overhead crane systems, and outline the advantages and recommended applications for each.

To begin, it can be helpful to know that there are three main paint classifications, which we will reference in this post: primers, intermediates, and finish coats. Primers are used to wet and adhere to the substrate (the steel surface or underlying metal) and act as an inhibitor to hinder corrosion. Intermediates are used to build film thickness. And, the finish coat offers aesthetic value, but it also provides surface resistance. Depending on the conditions of exposure, it must act as the first line of defense against weather and sunlight, open exposure and condensation.

In addition, there are also four types of protective coatings for metal: barrier, inhibitive, sacrificial, and combination.

Barrier coatings protect metal by preventing water, oxygen, and electrolyte from coming in contact with the underlying metal. Inhibitive coatings contain chemicals that hinder corrosion. They react with the cathode, anode, or other components (oxygen, electrolyte, acid). Sacrificial coatings provide galvanic protection. In other words, they corrode (sacrifice) instead of the underlying metal, providing electrons, which reverses the corrosion cell and transforms anodes to cathodes. Read more over here.

Providing Durable Protection

Many industries use metals like steel in producing or manufacturing their products. This is because metals are easy to manipulate, are cost-effective, and strong. But one of the disadvantages with metal is that it’s prone to rust, especially when exposed to harsh conditions.

The solution to this issue is using protective coatings. By doing so, industries can extend the lifespan of their products. However, the protective coating must adhere to the metal for it to be effective. Industries using wood, masonry, stone, solar panels, glass, and others use protective coatings to protect their surfaces.

Waterproofing Surfaces

Aside from making materials durable with coating, different industries use protective sealants to waterproof their properties. Excessive moisture is a problem as it can result in mold infection ruining roofs, siding, cement and masonry, windows and doors, and foundations. To maintain the buildings and properties of industries, waterproofing and sealing out moisture is the best remedy.

Aesthetic Purposes

Industries not only apply protective sealants and coatings inside their establishments, but they also do so for exterior surfaces. There are even different types of decorative sealants and coatings that industries use depending on the type of surface and structures. Such sealants and coatings have aesthetic properties like anti-dampening, anti-fungal, wash-ability, and weather resistance properties.

Summary of Protective Coatings Purposes

The most important methods different industries use protective coatings and sealants. From making their products or materials durable to making it more appealing, protective sealants and coatings can make this possible. Products and materials aren’t good enough if they easily degrade, so various industries should apply coatings and sealants. Also, coatings and sealants make products waterproof and more appealing.
