Our specially designed Z & C purlins not only provide economy to the building construction but also help in keeping the site clean and environment−friendly.

In structural engineering a profile means a hot rolled structural steel shape like an I-beam. In civil engineering, a profile consists of a plotted line which indicates grades and distances (and typically depths of cut and/or elevations of fill) for excavation and grading work.

In structural engineering, a pre-engineered building (PEB) is designed by a PEB supplier or PEB manufacturer with a single design to be fabricated using various materials and methods to satisfy a wide range of structural and aesthetic design requirements. What are the advantages of pre engineered building? Image result for PRE- ENGINEERED BUILDING Lower cost: Saving is accomplished in design, manufacturing and erection cost. Large clear span: In PEB the buildings can be given up to 90m clear spans which is the important advantage of PEB with column free space. Flexibility of expansion: PEB can be easily expanded in length by adding additional
