MANHOLE COVERS and GRATINGS

 

Our HISTORY: We have been in the manufacturing industry since 1958 with the production of high pressure VALVES1 for Oil and Gas sector as pioneer in Pakistan.  These products shouldered us to set up casting, machining, forging and fabrication facilities in Lahore, which helped us for the times till today. Time passed by and led us to start Induction furnace in late 1970’s and produced tons of iron ingots2 for the subsequent industries in the Punjab province. Latterly in 1987, we were forced to step into the realm of Spun Pipes3, as the furnace industry became victim of worst Power Load Shedding in early 1980’s.  Yet again, we were honoured to be pioneer for high quality ALPINE Spun Pipes production in Pakistan.  This coronation of ‘FIRSTS’ did not stop here. We introduced PPR Pipes4 for hot and cold water lines by importing them from Italy, with the brand “RIETTI” (1995). Envisaged with the history of innovation, we started manufacturing 5Grease Interceptors, Oil Interceptors, Floor Drains, Roof Drains, Parking Drains, and Floor Clean Outs for the first time again in Pakistan. There is a long history of customers in this regard, shows our proven record of high quality products. With the same token, we launched 6extra heavy duty, heavy duty, medium and light duty Manhole Covers, Gratings, Surface Boxes and Catch Basins.
