The total potential for PEBs in India is around 3.5 million tonnes, hundred million square meters per annum. But annually only 700,000 million tonnes of PEBs is being used, which is just twenty percent of the potential. The demand is roughly increasing by 12 to 15 percent per annum. The usage depends on conversion of potential concrete buildings to steel that is nearly seventy percent in the US, whereas in India it is less than 20 percent.
Infact, in India, PEB could make a major contribution in the governments 'Housing for All' policy as per SV Rao of Voortman. PEB's have been used for low rise buildings, but with the advent of new technologies and software, PEB's are a boon for low-cost, high-rise buildings.
IIT Chennai has done considerable work in this direction using thin gauge steel sections for constructing houses and dormitories upto five stories. These houses along with low cost building products can be completed in less than 100 days, says Rao. The Assam government has made schools every two km, with the help of IIT Guwhati.

Pre-engineered steel buildings have been in India for a couple decades now. Seen predominantly in the commercial, warehousing and infrastructure space, pre-engineered steel has now also morphed from simple structures to complex steel architectural marvels, thanks to advanced design capabilities in factories, and high quality steel.
The pre-engineered building (PEB) market is estimated to be around 600,000 MT per annum currently. The industry is driven by growth in infrastructure and manufacturing sectors. D. Raju, MD and CEO, Kirby, points out that advanced nations have long discovered the advantages of PEB. "The Indian smart city plan is taking inspiration from successful models elsewhere such as Japan, US, UK, China and trying to emulate the same in our local scenario. In these countries, you would be surprised to know that, the prefabricated steel construction is a preferred choice of commercial building material, with near 70 per cent market penetration!."
The main advantage of using pre-engineered steel is its rapid construction, affordability, architectural versatility, environment friendly material, flexibility for expansions, low maintenance, single source responsibility and earthquake resistance properties.

Pre-engineered buildings are typically delivered in just a few weeks after the approval of drawings, aided by advanced software. Foundation and anchor bolts are cast parallel with finished, ready-for-site bolting. PEB reduces total construction time of a project by at least 30% to 50%.This also allows faster occupancy and earlier realization of revenue.
Due to the systems approach, there is a significant saving in design, manufacturing and on-site erection cost. The complete structure is fabricated in-house and dispatched to the site to be erected using nut and bolt connections, with highly trained technicians.
Pre-engineered steel buildings use a combination of built-up sections, hot rolled sections and cold formed elements that basically provide for the steel frame work. It is designed to provide a complete building envelope system that is air tight, energy efficient, optimum in weight and cost and, tailor-made for client requirements. It is most suitable for any non-residential for any non-residential building and offers numerous benefits over conventional buildings.
But still, the relatively slow Indian uptake is a fact. Governments have in the past made policies to assist the industry, says SV Rao of Voortman Steel Group.
"The policy of the government of India could also be bolstered to help the industry. For instance, the tax holiday by the united AP government in the late nineties gave a big boost to the industry for a seven year period, and encouraged PEB industries to compete with RCC industries across India and become viable. Later, Uttaranchal in 2005 placed PEBs in scheduled items, and made the applicable tax five per cent which even today none of the states are able to do," he adds.

This resulted in many PEB sales offices working out of Uttaranchal. "This kind of encouragement is essential, as even after twenty years PEBs are mostly used for warehouses and industrial sheds and not enough has been done to educate builders and people in general," Rao concludes.
