There are various types of Parapet Jali offered by us that are short and slim walls constructed at the edges of a buildingâs roof, ideally around its edge. It very well may be constructed as a balustrade or other architectural shapes. A parapet is a barrier that is an extension of the wall at the edge of a roof, terrace, balcony, walkway or other structure. It is ideal for fencing around the structures to provide them attractive looks. It has remained an integral part of the construction industry, dating back to antiquity. The Parapet Jali is very effective and made for use in mosques and other places.
