Is it necessary to add a plinth beam between two columns, constructed for installing an iron gate?
Sand lime bricks: These are very strong & hard bricks. Sand for these should be coarse (but not very coarse), clean, free from salts or organic matter, with grains of assorted sizes, & well graded so as to have min voids.

Sand lime bricks:
These are very strong & hard bricks. Sand for these should be coarse (but not very coarse), clean, free from salts or organic matter, with grains of assorted sizes, & well graded so as to have min voids. Lime to be well burnt, free from ashes. It should be a high calcium lime, containing 90-90% of Cal. oxide & not more than 0.5% of magnesium oxide & filled in moulds. The moulded bricks are then placed for hardening in a closed cylinder called Autoclave for 10 hrs. Generally, the bricks are moulded by day & left over night to harden. The lime is slaked & intimately mixed with sand in proportion of 4-10%. Sand-lime bricks are much stronger than clay bricks & are uniform in color & texture.

If the columns and their foundations have been designed considering the loads (direct force and moment) from the iron gates then a tie beam at ground level is not necessary.
But a tie beam can help in reducing the foundation width in one direction as this beam will help to prevent overturning in one direction (if the columns are not joined by plinth beams towards wall boundaries). Another benefit of a tie beam is the extra strength provided in case of impact by a vehicle to the columns.
