Now a day, our observation about the steel structures, Industrial trusses form one of the major structural systems, which require accurate and economic design. Their span and corresponding weight plays an important role in planning the industrial area. The shape and configuration is decided upon the span, pitch, spacing of truss, various loads and naturally the weight. In this paper a humble attempt is made to compare various truss configurations with same span, pitch, spacing of truss regarding the weight aspects. All the trusses have been analysed and designed by Staad Pro, software for the span 20 m which are the most common spans used in practices. From the parametric study, the most appropriate span will be formulated considering geometric shape, weight, economy and other criteria.
