Primary Members/Main Frames

The main load carrying and support members of a pre-engineered building are “Primary Members”. Columns, rafters and other supporting members are part of main frame members. The shape and size of these members vary based on the applications and requirements.


The frame is erected by bolting the end plates of connecting sections together. All the steel sections and welded plate members are designed in unity with the appropriate sections as per the latest international codes and standards such as AISC, AISI, MBMA and IS to meet all the client disclaimers.
