Shanker Wire Products Industries (SWPI) have been engaged in manufacturing weights in India exclusively since 1961. The nature of the world is changing very rapidly due to revolutionary development in the field of Science & Technology. It has brought a marked change in the requirement of weights of various specifications, shapes, sizes, designs etc.
