In below picture railing started with one design rod. It will look good if you keep this kind of design rod at the starting of railing.
Last time for my house I purchased this design rod it cost me around 150 rupees. Instead of keeping plain rod you can keep this design rod which will give better look with less cost
Cast iron pieces:
Cast iron pieces will give very good look for the grill design or railing designs. You need to select the design which suits for your house based on the elevation plan. You can use them in gate as well. In K. R Market, Bangalore vendors will sell this in KGs. When I brought this from market, one item ws costing around 65/- per KG and another item was costing around 85/- rupees.
Below are the items which brought from market
