In the beginning, chain-link fences with colored plastic planks were fixed around these substations. It was made to depict the presence of a concealed barrier. Later on, it was found out that more was needed as the intruders were easily crossing the chains and breaking in.

Next came the era of masonry utility walls, but these, too, stayed for a shorter time as the copper had been quite expensive. The intruders and burglars took advantage of the situation and began stealing the copper used to build and fix large utility walls.
Finally, a practical and cost-effective solution for this problem was devised -Precast utility walls. They proved to be a better aid in shielding and guarding the substations.

Due to the factors like easy and quick installation, time savvy jobs, fewer labor requirements, and affordability attribute, concrete fences are thought to be the most enduring and reliable choice.

In addition to this, industrial units and substations with the need for relatively taller walls and fences, concrete walls are one of the best alternatives. They can be built to greater lengths and heights, and faster to install than CMU walls. Apart from this, concrete utility walls provide excellent safeguard and security against the intruders -thieves, ribbers, burglars, and other people with ill-intentions.
