What Is Bezinal® Coating? 

In the energy industry, components' safety, longevity and reliability are vital, regardless of the elements or environment. Therefore, telecommunications and energy providers prioritize coating wires and other components to ensure they perform to the expected level. There are various coating options, but Bezinal® coated wire is rapidly becoming a preferred option.

Bezinal® coatings offer superior corrosion resistance, durability and reliability for many applications. They meet the energy industry's stringent quality and safety requirements and have a unique ability to withstand the elements, even in environments prone to corrosion. Understanding the advantages of Bezinal® coating is the first step to choosing the right coating for your application.

How Do Bezinal® Coatings Work?

Bezinal® coatings are compounds that bond with a metal substrate like steel to create an extra passivation layer to prevent corrosion. There are two options for applying a Bezinal® coating — hot dipping and electroplating.

Once the coating is applied, it strengthens the entire component, creating a lightweight, flexible barrier layer to withstand impact and vibrations. In addition, they provide considerable protection from the elements, increasing the longevity of energy components in outdoor, humid or high-alkaline settings.

The Advantages of Bezinal® Coating

The innovative composition of Bezinal® coating offers many advantages for active corrosion protection. This combination of zinc and aluminum in the coating gives a superior performance regarding corrosion, heat resistance, durability and processability. Some of the many advantages of Bezinal® coatings include the following:

  • Corrosion resistance: Corrosion resistance is one of the most vital elements of effective coatings. Benizal-coated wire resists corrosion up to six times longer than hot-dip galvanized wires. They can last up to eight times longer in heavily polluted areas due to the aluminum oxide passivation layer.
  • Heat resistance: Hot-dip galvanized wires are susceptible to alloy layer growth under high temperatures. The inhibiting action of the aluminum in Bezinal® coatings eliminates alloy layer growth.
  • Cathodic protection: Bezinal® coatings provide uncoated steel areas, where the active coating acts as an electrical current that counteracts steel corrosion.
  • Durability and longevity: These coatings' exceptional corrosion resistance increases steel's longevity and increases product reliability.
  • Flexibility: Bezinal® coatings are suitable for many applications across industries, from electrical components to alternative energy coalitions and more.

Bezinal® coatings are subject to many corrosion tests, standardized product development and customer-specific tests — in-house and at independent research facilities worldwide — to ensure quality and performance.

Applications of Bezinal® Coatings

Bezinal® coatings are an excellent option for many applications across industries.

  • Utility poles, transmission towers and communication equipment: Reliable and effective communications systems have numerous moving parts, and users must be able to rely on the quality of the components to communicate. The anti-corrosion properties synonymous with Bezinal® coatings make them perfect for protecting various electrical components in communications systems from the elements.
  • Outdoor infrastructure in multiple climates: Other coating options are often specific to a particular climate. Bezinal® coatings are suited to any environment, regardless of temperature or humidity.
  • Automotive alternatives: Bezinal® coatings can support the reliability and longevity of various automotive parts, including springs, steering systems, drive trains, windscreen components and alternative energy sources.
  • Industrial springs: Corrosion is often the primary cause of breakdowns and equipment failure in industrial applications. Bezinal® coatings offer the necessary corrosion protection to create reliable and durable springs.
  • Agricultural equipment: Machinery and other equipment in the agriculture industry must withstand the elements and other harsh environments. Bezinal®-coated machinery, fencing and other agricultural equipment retain their durability even in the most challenging conditions.
  • Medical wire: Smooth processability and long shelf life are essential for medical applications, and Bezinal® coatings provide both, meeting FDA and EFSA quality standards.
  • Coastal environments: In a coastal environment, stainless steel and other metals are prone to corrosion. Bezinal® coatings last two to six times longer in heavily corrosive areas.

Bezinal® vs. Galvanized Coatings

When a Bezinal® coating is applied to steel, it improves the performance of regular galvanized steel. Bezinal® coatings are ideal for demanding environments. While galvanized steel is a good option for corrosion protection, it lacks the longevity of Bezinal® coatings, meaning more frequent maintenance, repairs and replacements.

Bezinal® coatings give additional strength in corrosion and cathodic protection, combined with stable coating integrity. It also presents a more eco-friendly alternative, as the strength of the coating eliminates the need for environmentally unfriendly and expensive additional processes.

The Future of Bezinal® Coating

Bezinal® coatings offer a fresh and innovative approach to ensuring safety and quality in the harshest conditions. Ongoing research and advancements in Bezinal® coating technology present exciting opportunities for the future, including potential improvements in already impressive corrosion resistance, conductivity and durability.
