Products and services

• Collector Bars Cathode collector bars for aluminium electrolysis with flats in mild steel and custom compositions up to 4500mm length, 300mm width, and 20-80mm thickness. Designed for aluminium smelter operations.
• Hydraulic Systems Industrial hydraulic systems including power packs (100-350 kg/cm2, 50-5000 litres), cylinders (up to 400mm bore, 350 bar, 5000mm stroke), presses (up to 450 MT), special purpose machines (SPMs), manifolds, and accessories for industrial applications.
• Refractory Materials High-quality refractory materials including fire clay and high alumina bricks (up to 90% alumina), slide gate accessories, castables, gunning mixes, and raw materials like white fused alumina and calcined bauxite. Used in high-temperature industrial processes across steel, aluminium, cement, and petrochemical plants.
• Ceramic Welding Hot repair technology for industrial furnaces under operating temperatures using ceramic and metallic particles projected with oxygen onto hot refractory surfaces, creating long-lasting bonds equivalent to metallic welding. Eliminates the need for plant shutdowns during refractory repairs.
• Shotcrete Applications Wet-method application of monolithic refractory materials using high pressure pumps (approx. 250 bar) over distances up to 80m, with simultaneous accelerator mixing for industrial furnace linings.
• Refractory Services Application of refractories for steel plants, aluminium plants, cement plants, and petroleum plants, including Annual Maintenance Contracts (AMC) for reheating furnaces, bell annealing furnaces, and coke ovens.
• EPC Services Turnkey Engineering, Procurement, and Construction services for ferrous and non-ferrous industries, air pollution control, oil and gas, refractory engineering, infrastructure projects, hydraulic systems, electrical substations, and water management. Includes design, equipment supply, erection, and commissioning.
• Air Pollution Control Systems Environmental control equipment including electrostatic precipitators, bag filters, bag houses, flue gas desulphurisation (FGD) systems, thermal oxidisers, and solvent recovery systems for industrial emission control.
• Raw Materials & Consumables Supply Sourcing and supplying industrial raw materials including bauxite, caustic soda, calcined alumina, petroleum coke, coal tar pitch, and consumables like cathode blocks and aluminium fluoride for metallurgical and industrial processes.
• Operations and Maintenance Services Operations and maintenance services for industrial plants including refractory application and maintenance, and specialized services such as Ceramic Welding and Shotcrete Applications for ongoing plant operations support.
