We manufacture & export world-class performance Flanges

Flanges produced in our Mumbai factory, carries a promise of quality and consistency. Metal-Tech Engineers continues to meet customers’ needs through global quality standards from original design to distribution. Metal-Tech Engineers manufactures to global standards. We are one of the leading importer, stockholder, suppliers & exporters dealing in Flanges since 1990. When procuring raw materials to manufacture Flanges, our primary responsibility is to ensure that same quality and consistency exists in our supply base.

Metal Tech is excellently equipped for the production of tailor-made, high-grade flanges. In our forging shop, an advanced, automatically controlled steel bar furnace with a length of over 12 m heats the raw material up to approx. 1,100°C before rings or flanges with an outside diameter of up to 2,800 mm are formed using our face plate bending machine.
