Manufacturing note
Square tube is formed from coil and then ran through a series of dies. It’s welded from the inside to form its shape. Square tubes are generally used for maintenance and structural purposes. Some examples of square tubing applications would be building construction, railings, and sign posts. Nascent fittings INC has created a notable place in the market, engaged in manufacturing and exporting a wide range of square pipes. Our offered square pipe is designed for fulfilling the wide demands of water conveying applications in residential, commercial and industrial sectors. These square pipes are checked on various parameters under the supervision of quality experts before the final dispatch. Nascent fittings offer varied specifications keeping in mind the needs of customers. Square pipes are well-convenient for use in aggressive environments such as chlorinated seawater and acidic, chloride-containing media. These products are manufactured with exceptional raw materials.
