  Standard reinforcing bars, also known as rebars, typically come in various sizes and weights. The dimensions and weights can vary somewhat depending on the specific standard used (such as ASTM in the United States or BS in the United Kingdom). Here are some common sizes and weights for reinforcing bars: Rebar Sizes : Rebars are usually designated by their nominal diameter in millimeters. Diameter : Common diameters range from 6 mm to 50 mm or more, with typical increments being 6, 8, 10, 12, 16, 20, 25, 32, and 40 mm. Weights : The weight of a rebar can be calculated based on its diameter. The weight is usually specified in kilograms per meter (kg/m). Weight Calculation : The weight W W W of a rebar of diameter d d d in millimeters can be calculated using the formula: W = π × d 2 4 × Unit weight of rebar W = \frac{\pi \times d^2}{4} \times \text{Unit weight of rebar} W = 4 π × d 2 ​ × Unit weight of rebar Where: π \pi π (pi) is approximately 3.141...

1. Cast iron piles.  Cast iron piles are hollow tubes of cast iron having inner diameter 20 to 40 cm and wall thickness 20 to 30 mm. These are generally 4 metres in length and for longer lengths these are joined by a suitable device. Cast iron being a brittle material, these piles are provided with helical screws at the lower end and the whole assembly is rotated to drive the pile inside the soil. Piles with helical screws are generally known as screw piles. Cast iron piles are suitable for shallow foundations and are suitably employed for the foundations of marine structures, light weight bridges and buoys anchors. 2. Cement concrete piles These are of the following types : A. Cast-in-situ piles These piles are cast with cement concrete at the place where   these have to carry superimposed load. For casting the pile, a hole is driven by excavating with an Auger or driving a casing. The hole is then filled up with cement concrete...
