At Rameshwar Metal India, we take pride in being one of India’s most trusted manufacturers, suppliers, and exporters of stainless steel welded tubes and pipes. Our products are crafted using premium-quality stainless steel strips sourced from reputable vendors, ensuring superior durability and performance.
We utilize the advanced Tungsten Inert Gas (TIG) welding process to seamlessly join the strips after they are shaped into tubular forms. Our mill’s bead scarfing equipment effectively removes the welded bead, ensuring a smooth and flawless finish.
Each stainless steel pipe and tube undergoes a rigorous process, including straightening, pickling, and solution annealing, to enhance quality and longevity. Before packaging and dispatch, our products are meticulously tested to meet the highest industry standards.
At Rameshwar Metal India, we are committed to delivering excellence in every tube and pipe we manufacture and supply.
