We are well equipped with CNC Angle Lines Machines which enables punching, drilling, stamping, cutting of steel in any shape & size. Along with this, we also have various CNC Shearing & Bending Machines, Power Press Machines, Drilling Machines, and MIG Welding Machines.

We also have the latest Roll-forming Lines to manufacture C & Z Profiles ideal for Solar Module Mounting Support Structures, Pre-Engineered Building Construction, and Metal Beam Crash Barriers.

Our trained inspectors, periodic maintenance check-ups of machines, system upgrades, and a streamlined production flow-chart enable us to offer products and services at par excellence

Our Fabrication plant has integrated facilities from Design, Engineering, Fabrication of all types of structures as per various Indian and international standards.

At KPB, every stage of production and execution is manage with the help of more than 12 strong load-bearing EOT cranes and 2 mobile cranes, ensuring efficient, safe, and easy material handling at different stages.

Each & Every product undergoes a series of stringent quality checks before they reach the customers. With an in-house testing facility, the product is assured of quality and compliance with required standard norms.

With our latest Galvanizing Kettle setup (8 Mtr. Long X 1 Mtr. Wide X 1.8 Mtr. Deep), we ensure that our structures are strong, corrosion-resistant, and aesthetically well finished.

The three main steps in the hot-dip galvanizing process are:

  • Surface Preparation
  • Galvanizing
  • Dichromate Treatment

Surface Preparation includes Degreasing, Pickling, and Fluxing. The purpose of surface preparation in the hot-dip galvanizing process is to obtain the cleanest possible steel surface by removing all of the oxides and other contaminating residues.

Degreasing baths have an alkaline caustic solution that removes organic contaminants such as dirt, oil, and grease from the surface of the steel. After degreasing the steel is rinsed with water.

Pickling Tank has diluted solution of HCL which removes oxides and mill scale. Once all oxidation has been removed from the steel, it is again rinsed with water.

The fluxing purpose is to clean the steel of all oxidation developed since the pickling of the steel and to create a protective coating to prevent any oxidation before entering the galvanizing kettle.

After degreasing, pickling, and fluxing, the surface of the steel is a near-white metal, clean and completely free of any oxides or other contaminants. And it is further moved for Galvanizing Process into Galvanizing Kettle.

The galvanizing process is commonly known as HDG (Hot Dip Galvanizing). In this process after surface preparation, Steel components are dipped into a molten zinc bath a series of corrosion-resistant, zinc-iron alloy layers are formed by a metallurgical reaction between the steel and zinc.

This reaction is a diffusion process, so the coating forms perpendicular to all surfaces creating a uniform thickness throughout the part. This process has a distinct advantage over all other corrosion protection methods.

Dichromate Treatment is considered as post-treatment to enhance the galvanizing coating minimizing white rust. One of the most commonly used treatments is quenching.

This quenching tank contains water with sodium dichromate to create a passivation layer that protects the galvanized steel during storage and transportation.

Thus, in short, Hot Dip Galvanizing forms a sacrificial protection Zinc – Iron Alloy coating, Metallurgical bonded to the base steel. This coating is abrasion, resistant, reliable, and durable, thus providing maintenance-free protection to steel structures. 

Galvanizing provides superior corrosion protection through a metallurgically bonded finish which reduces maintenance cost and environmental impact over the life of the steel.


KP Buildcon Pvt. Ltd. has been a name to reckon with in the global electrical arena. We bring all our products with leading-edge technology which supplement the existing range of products in order to complete the scope of the substation equipment such as outdoor offload Disconnector (Isolator) as per IEC 62271-102.

We started manufacturing and supply of the isolators in the year 2020 and within a short span of time, we have made our presence in Gujarat as well as in India.

In a power network, a Disconnector is used to ensure that a piece of electrical equipment is completely de-energized and isolated for service or maintenance. KP Buildcon Pvt. Ltd. offers a wide range of reliable and energy-efficient Disconnectors ranging from 12 kV to 420 kV.

We have completed the development of offload Disconnector up to 72.5 kV and we are now in the development stage for 245 & 420 kV Disconnectors.
