What are Pre-engineered buildings?

Pre Engineered Buildings are the buildings which are engineered at a factory and assembled at site. Usually PEBs are steel structures. Built-up sections are fabricated at the factory to exact size, transported to site and assembled at site with bolted connections. This type of Structural Concept is generally used to build Industrial Buildings, Metro Stations, Warehouses etc.

Pre-engineered steel buildings use a combination of built-up sections, hot rolled sections and cold formed elements which provide the basic steel frame work with a choice of single skin sheeting with added insulation or insulated sandwich panels for roofing and wall cladding. The concept is designed to provide a complete building envelope system which is airtight, energy efficient, optimum in weight and cost and, above all, designed to fit user requirement like a well fitted glove.

Advantages:

Reduction in Construction Time: Buildings are typically delivered in just a few weeks after approval of drawings. Foundation and anchor bolts are cast parallel with finished, ready for the site bolting. In India the use of PEB will reduce total construction time of the project by atleast 50%. This also allows faster occupancy and earlier realization of revenue.

Lower Cost: Due to the systems approach, there is a significant saving in design, manufacturing and on site erection cost. The secondary members and cladding nest together reducing transportation cost.

Flexibility of Expansion: Buildings can be easily expanded in length by adding additional bays. Also expansion in width and height is possible by pre designing for future expansion. Larger Spans: Buildings can be supplied to around 80M clear spans.

Quality Control: As buildings are manufactured completely in the factory under controlled conditions the quality is assured.

Low Maintenance: Buildings are supplied with high quality paint systems for cladding and steel to suit ambient conditions at the site, which results in long durability and low maintenance costs.

Energy Efficient Roofing and Wall Systems: Buildings can be supplied with polyurethane insulated panels or fiberglass blankets insulation to achieve required U values.

Architectural Versatility: Building can be supplied with various types of fascias, canopies, and curved eaves and are designed to receive pre cast concrete wall panels, curtain walls, block walls and other wall systems.

Single Source Availability: As the complete building package is supplied by a single vendor, compatibility of all the building components and accessories is assured. This is one of the major benefits of the pre engineered building systems.
