The company's consolidated net profit stood at 3.85 billion rupees ($46.24 million) in July-September, against a loss of 565.9 million rupees in the year ago period, it said in an exchange filing.

Welspun, which also operates in the United States and Saudi Arabia, said its revenue from operations surged more than two-fold to 40.59 billion rupees, backed by its core steel products.

However, expenses also rose, jumping 73% on year owing to a 41% expansion in key raw material costs.

Analysts had flagged strong demand for steel during the September quarter, driven by construction and infrastructure-related activities.

India in September imposed anti-dumping duty on steel wheels produced in China to promote domestic manufacturing and stabilise prices, after steel imports from China hit a five-year high in April-August.

Shares of Welspun closed up 1.03% at 457 rupees before the results, taking total gains this year to 90.9%.
