Dular Steel Products (DSP) began manufacturing balls in the 1970s and has grown into a specialist producer of precision grade balls across multiple metals and special materials. Production is guided by recognised international ball standards, with every order aligned to drawings or detailed discussions about the end application.
From common carbon and chrome steel balls to stainless, brass, copper, silver and tungsten carbide, DSP also supports niche requests such as odd sizes and small runs that are hard to source in the open market.
DSP’s founder brought decades of experience, including involvement in India’s first ball manufacturing plants. The business has since passed to the next generation while retaining the same engineering-driven mindset and emphasis on quality.
DSP is working towards environmental certifications and has introduced solar power to offset part of its energy needs.
