Why are dams built?

Dams are built to provide water for various basic needs such as human consumption, for irrigating fertile and semiarid lands, control flooding, and generate electricity and even for use in industrial processes.

We provide different type of fasteners & components for different type of Dam construction designs as per requirements.

Importance of a fasteners in dams’ construction

Fasteners are widely used in to hold two ends or objects together, mainly in dam construction rock bolt & Anchor bolt very common bolt which is used for every dam construction. A fastener can be a special type of bolt, nut, stud that has spirals on its sides, one end no spirals heavy hex nut or anything else customisable.

Various kinds of Fasteners are utilized in the business for various purposes. A cars prerequisite for fastener will be not quite the same as the necessity of that of a fastener that is utilized in Dam Construction.

Rock Bolt

Rock bolts are steel bars implanted in a hole drilled into the RCC, earth or mountain of a rock formation to provide support to the roof or sides of the cavity. Rock bolt support can be utilized in any exhuming calculation, quick to apply, and is moderately reasonable. The establishment can be completely motorized. The length of the bolts and their dividing can be fluctuated, contingent upon the support prerequisites.
