Concrete is a material with a high compressive strength but a low tension strength. In reinforced concrete and reinforced masonry constructions, rebar (short for reinforcing bar), also known as reinforcing steel or reinforcement steel, is a steel bar or mesh of steel wires used as a tension device to strengthen and hold the concrete in tension.

Electric equipment is connected to the alternating current (AC) mains electricity power supply in buildings and other locations via AC power plugs and sockets. Voltage and current ratings, shape, size, and connector type all change amongst electrical plugs and sockets.
ISI Registration for Polyethylene Pipes for Irrigation IS 12786:1989
by Sagar Sharma on 2022-01-10
Drip and mini sprinkler systems frequently use polyethylene irrigation pipe. These pipes are manufactured of high-grade virgin polyethylene and are highly resistant to UV radiation, chemicals, and agricultural fertilisers. The smooth inner surface of these pipes reduces frictional losses.
