Hire the Best Industrial Engineering & Construction Company in Kolkata
Building a factory is not the same as building an office. A factory floor has to handle heavy forklifts and vibrating machinery 24 hours a day. The walls need to withstand heat and dust. The electrical system has to handle massive power loads without tripping. If you are setting up a plant in Kolkata or West Bengal, you need a contractor who understands industrial layouts. You cannot afford a floor that cracks or a roof that leaks over expensive equipment.
The Real-World Problem
When you build a factory, things get messy fast. You usually have a different contractor for the steel shed, another for the concrete base, and a third for the wiring. The trouble starts when they don’t talk to each other. The foundation bolts end up in the wrong spot for the machine. The cable trenches are too shallow. The floor isn’t flat enough for the forklift. These mistakes stop you from starting production on time. You need one team that handles the whole mess.
Our Solution
Rainbow Infrastructure, an industrial construction company in Kolkata, fixes this by doing the work ourselves. We are one of the few companies in Kolkata that has its own tea,s for Civil. Steel and Electrical work. We don’t just put up the roof. We pour the thick concrete floors, we weld the storage tanks, and we wire up the high-voltage panels. We build the whole facility around your machines so that when you turn the power on, everything actually runs.
Our Capabilities
Heavy-Duty Plant Flooring & Roads
The ground in a factory takes a beating. We construct reinforced concrete roads, drains, and industrial-grade flooring that stand up to heavy truck movement and chemical spills. We completed the civil works, including reservoirs and warehouses, for the Berger Paints plant in Howrah.
Powering the Plant
A factory needs a lot of power without interruptions. We build the systems that keep the machines running. We, as the industrial electrical contractors in Kolkata have set up full Electrical Substations and Gas Insulated Switchgear (GIS) for big power companies like CESC. We handle the heavy wiring from the grid right to your control panel.
Building Industrial Tanks
You need strong containers for your raw materials. So we built steel tanks for acid like the Sulphuric Acid for JSPL and large water reservoirs. We make sure the welding is perfect so there are no leaks and the metal stands up to harsh chemicals.
Structures that Move Material
We build the steel frames that hold your conveyor belts and crushers. We understand how material flows through a plant. As an industrial engineering company in kolkata, we have built these heavy frameworks for iron ore plants and crushing units where the structure has to withstand a lot of vibrations.
Proven Performance
We have worked inside some of the busiest plants in India. Our track record includes executing critical expansion works for HNGIL in Rishra and building glazing structures for Wirpo. Whether it is a crushing plant for Essel Mining or a radiation plant for Tarsons Products, we have delivered industrial infrastructure that works.
