Metro/Railway: India accounts for having the largest train system in Asia and the Metros make up for the lifelines of our metropolitan cities, with that being mentioned it’s quite obvious it remains one of the staples for transportation, and the products in their making need to be sturdy and reliable enough.

MHIL’s expertise and dedication towards quality has been a core element towards this particular industry in terms of Boilers, Rail coaches, Automobile frames & bodies, Locomotive fireboxes, Storage tanks, Sheet metal work.
