Patta Patti
Patta Patti is produced under the correct guidance of the experts. They use the best quality hardened SS to make this product. Patta Patti is mainly utilized in the construction because of its solid structure. Also, it is used in various other applications because of its light-weighted, powerful structure and easy establishment. Patta Patti is resistance to erosion and so, they are used in synthetic concoctions, petrochemical, and vehicles. Patta Patti is fabricated by utilizing the quality treated steel as well as present-day procedures following strict rules and regulations. They are also customized in different shapes, size, and forms as requested by the customers.
