Our Galvanization Process
1. CNC Surface Finishing Preparation
This step makes the surface clean and smooth to provide the best surface for the zinc to stick to. The use of CNC machinery reduces the surface roughness of the metal and eliminates any impurities, rust, and mill scale on the surface of the metal before galvanizing. This preparation makes the zinc coating stronger and more efficient as compared to those that receive a single coat.
2. Galvanizing Treatment
The actual galvanizing is done by dipping the metal components that have been prepared into a kettle containing molten zinc. This process forms a series of zinc-iron alloy layers with a metallurgical bond with the base metal and pure zinc layer on the surface. This makes it possible to have the highest protection against corrosion and a durable barrier to the metal surface.
3. Post Treatment
Our post-treatments include rinsing in a passivation solution, chromate dipping, and sealants to improve aesthetic properties and enhance corrosion protection, making components ready for immediate use.
Advantages of Galvanizing Process
- Good Protection
The galvanizing process provides superior protection, and complete coverage against corrosion by forming a protective hard coating.
The Galvanized layer is capable of healing itself if it gets scratched and therefore preserves the metal and does not rust.
- Save Money
It greatly minimizes upfront maintenance required, which means cutting down on the amount of money that would be spent on repairing the building in the future.
Galvanized metal is more durable than other types of metal and thus requires less replacement, thus saving money.
- Environmental-friendly
The process also promotes environmental sustainability through product durability and full recyclability of the product.
Employing galvanized steel helps to save resources and has a lesser effect on the environment.
Materials for Galvanizing
Steel and Iron
The most preferred materials to be galvanized are steel and iron because of their strength and versatility in applications such as construction and automotive industries. The galvanizing done by our team improves their anti-rust and anti-corrosion features and therefore enhances their lifespan. The process creates a layer of zinc that bonds with the steel or iron and then creates layers of zinc-iron alloy and an outer layer of pure zinc.
Alloy Steels
Other types of steel are steel alloys which are produced by adding steel with other elements to improve its characteristics like strength and wear. Our professionals ensure that the process of galvanizing is well done with certain alloying additions. This may need some form of pre-treatment or some form of preparation to ensure that the coating adheres well and is of good quality.
Cast Iron
The use of galvanizing both ductile and malleable cast iron is also done although not as frequently as that of steel. Our specialists describe the problems related to high-carbon cast iron, which can lead to the formation of graphite during galvanizing. Regarding the pre-treatment process, abrasive blasting is applied to the cast iron before proceeding with the galvanizing process.

Types of Galvanizing Process
Hot Dip Galvanizing
Prolean engineers use hot dip galvanizing where the metal parts are dipped in molten zinc. It forms a strong and anti-corrosive layer which is suitable for structural steel and other applications in the exterior. This process of creating a thick zinc layer offers a protective barrier that is long-lasting and resistant to extreme environmental conditions.
Sherardizing
Sherardizing is a diffusion process that involves the heating of objects with zinc dust and an insusceptible material such as sand. This procedure is commonly conducted in a closed rotating drum at a temperature of 320-500°C. Once the zinc/iron alloy coating has been developed, the items are then treated with zinc phosphate to obtain a fresh surface. The coating spreads and adheres to the base material and ensures that it covers the items uniformly regardless of the shape that the latter has.
Electroplating
Electroplating is the process of coating an object with a layer of metal through electrodeposition. It involves using controlled electrolysis to transfer metal from an anode (the metal source) to a cathode (the object to be coated), with an electric current passing through an electrolytic bath solution. Electroplating is commonly used to apply a layer of a less expensive metal, like nickel or copper, onto a base metal.

Applications of Galvanization
Agriculture, and Farming
Galvanizing is commonly used in agriculture to protect equipment and structures from corrosion, preventing rust and reducing maintenance costs. It provides reliable and economical protection for barns, trailers, feeding equipment, and support structures, contributing to efficient and sustainable farming practices.
Construction and Infrastructure
In construction and infrastructure, galvanizing enhances the corrosion protection of metal parts. We use galvanized steel in structural frames to protect them from harsh weather, reducing the need for frequent repairs.
Automotive and Transportation
In automotive and transportation, galvanizing is very vital in eliminating the rusting of auto parts such as body, frames, and chassis. The process ensures that cars and trucks are well-maintained and thus do not need frequent repairs.
Energy and Utilities
We apply this process to protecting parts in power plants, electrical networks, and renewable energy plants like windmills. Since the galvanized components are strong and durable, they can be used in hard areas to reach hence ensuring the longevity of energy systems.
HVAC and Ventilation Systems
In HVAC and ventilation systems, galvanizing prevents the ducts, pipes, and structural parts from corroding. This protection contributes to the effectiveness of the heating, ventilation, and air conditioning systems and their longevity. The moisture and temperature do not have any impact on the galvanized components hence they do not need frequent maintenance.
Renewable Energy
The renewable energy industry employs the process of galvanizing to protect solar panels, wind turbines, and other structures. Steel coatings also can perform well in extreme environmental conditions; therefore, green energy systems are long-lasting. This corrosion resistance is important for the sustainability of renewable energy structures and therefore helps in the provision of clean energy with minimal maintenance.
