Advanced Protection And Durability For Solar Equipment Through Cold Galvanizing
The exponential growth of the solar energy sector in Brazil highlights the pressing need for innovative solutions to protect equipment from corrosion. Solar plants, which currently exceed 18,000 units with an annual production of over 10.3 gigawatts, represent a significant investment in the country’s energy future. The Brazilian Photovoltaic Solar Energy Association (Absolar) reveals that solar energy has already resulted in over R$ 189.3 billion in new investments and created approximately 1.1 million jobs since 2012, in addition to having a positive impact on the environment by preventing the emission of 47.7 million tons of CO2.
The Challenge Of Corrosion In Solar Equipment
In this promising scenario, maintaining the integrity of equipment in solar plants presents a significant challenge. Traditionally, hot galvanizing is the most adopted technique to protect iron and steel structures from corrosion. This process involves immersing metal parts in molten zinc, creating a robust protective layer. However, climatic adversities and necessary maintenance interventions – which may include cuts and welds – can compromise this protection, exposing the equipment to corrosion.
Cold Galvanizing As An Innovative Solution
This is where cold galvanizing stands out as a revolutionary solution. Ideal for both spot repairs and applications on new complete parts, this technique offers protection equivalent to hot galvanizing without the need for specialized labor. One of its greatest advantages is the ease of direct application on site, whether with a brush or spray gun, eliminating costs related to relocation or disassembly.

Quimatic, a pioneer in introducing cold galvanizing products to the Brazilian market, leads with innovations that offer not only a physical barrier against corrosive elements but also cathodic protection. The zinc used in its solutions with a purity of 99.9% acts as a “sacrificial metal,” corroding before the base metal and ensuring continuous protection even in the event of damage to the protective layer.
Its products, such as the dark gray CRZ and the aluminized GALVALUM, meet the strict ASTM A 780 and ABNT 6323 standards, ensuring high resistance against corrosion. Tests show that Quimatic’s cold galvanizing products can withstand over 1,200 hours in salt spray chambers, equivalent to more than five years of protection under extreme weather conditions.
The Impact Of Cold Galvanizing In The Solar Energy Sector Is Undeniable. By providing a practical and long-lasting solution for corrosion protection, plants can ensure the longevity of their equipment. This not only optimizes energy production but also contributes to the sustainability of the sector, aligning with the goals of accelerated growth and environmental responsibility in the country.
Quimatic also offers an online course on cold galvanizing, demonstrating its commitment to education and the promotion of best practices in the sector. For professionals and companies seeking excellence in maintenance and protection of equipment, cold galvanizing presents itself as a strategic choice to face the challenges of Brazil’s energy future.
