Black Steel Pipes & Tubes |
 |
|
| |
| We produce high quality ERW Tubes / Pipes in various sections and thickness. Steel Strings are cut into required width slitting machines and fed to the pipe plant through feed cages. Further black tubes are galvanized at the galvanized plant and all tubes go through quality checks before dispatch. High quality steel stripes for pipes are directly sourced from primary or produced at our own rolling mill. All the pipe and tube products confirm to Indian & International standards. |
