Fabrication

At Jalpa Devi Engineering, our fabrication equipment is precisely developed to suit the ever-increasing need for innovative and unique constructions. We seek to create exceptional technical solutions by merging cutting-edge technology with modernistic and functional designs. We manufacture steel superstructures for cable stays, suspension, and extra-dose bridges weighing up to 150MT per structure. 

USPs

  • Advanced 3D designing, modeling, and simulation software: By making use of cutting-edge 3D modeling, design, and simulation technologies, we improve product optimization and visualization, guaranteeing improved product quality.
  • Robotic cutting and welding lines: Our fabrication plant uses robotic cutting and welding lines for optimal weld quality and to guarantee the durability and strength of our constructions.
  • CNC drilling and laser sensing: CNC drilling machines equipped with laser sensing technology provide precise drilling, making certain all components fit accurately within the greater structure.
  • Automatic beam and girder welding line: We can precisely weld and straighten large-scale constructions using our state-of-the-art automated beam and girder welding line, capable of handling girders as tall as 2.5 meters.
  • Controlled torquing: Our fabricated structures are torqued appropriately within 5% of the torque value, assuring secure joints and connections for strength and stability under challenging conditions.

I-Girders

Jalpa Devi Engineering produces high-grade I-girders, which are essential to building bridges. These girders are made to support large weights and offer crucial stability and support. Using modern fabrication procedures, we ensure that our I-girders fulfill specific requirements and provide excellent stability, making them appropriate for a variety of infrastructure applications.

Open Web Bridge Girders

Our open web bridge girders are engineered to deliver exceptional strength and durability for bridge construction. These girders are lightweight yet maintain structural integrity, making them ideal for long-span projects. We employ precise fabrication methods and stringent quality control measures to produce open web bridge girders that adhere to the highest standards of quality and safety.

Modular Pontoon

Jalpa Devi Engineering specializes in the design and manufacturing of modular pontoons. These versatile structures provide a dependable and efficient solution for a variety of industrial applications, including material handling and waterway transportation. 

Jalpa Devi Engineering specializes in the design, modeling, and fabrication of heavy-duty manufactured structures that satisfy RT and UT specifications. These structures are necessary for steel superstructures for bridges, material handling, and transit via waterways. Our product line includes launching girders for bridge construction, dumb modular pontoons, deck anchorages, and girders and beams for bridge superstructures. 

We use innovative technology and strict quality control to ensure that each component satisfies the highest requirements of durability, dependability, and safety, resulting in sturdy solutions to complex engineering challenges. Our fabrication capabilities at Jalpa Devi Engineering are distinguished by modern technology, accurate design, and a dedication to quality.

Heat Treatment Processes Offered by Jalpa Devi

Annealing: We treat metals like copper, aluminum, silver, steel, and brass. Our furnaces handle large volumes, of heating, holding, and cooling metals to soften and improve ductility.

Normalizing: We raise the metal’s temperature above its critical point and cool it in the air to refine its grain structure and reduce internal stresses. Suitable for our 10 MT Bogie Hearth Furnace or 9 MT Bell Furnace.

Hardening by Forced Air Cooling: We heat metals above their critical temperature and quickly cool them with forced air for increased hardness. Our furnaces ensure precise control and efficient cooling.

Water Quenching: Our 10 MT Bogie Hearth Furnace and 1 MT Chamber Furnace provide rapid cooling to enhance material hardness. Metals become extremely hard when quenched in water.

Tempering: After hardening, we temper metals to reduce brittleness and increase toughness using our 9 MT Bell Furnace, capable of handling various materials with precise temperature control.
