the most common primary framing systems are shown below, asymmetrical
framing system and multi span framing system with unequal width module
are also possible, but may require more engineering time and possibly
longer deliveries. For more information on framing system please
contact engineering at Modern Prefab Systems Pvt. Ltd.
Primary members consists of columns, rafters, beams etc.
These are fabricated from high strength HR Plates. Plates
are cut to size using Hi Tech CNC and Oxy Cutting
machines, which are installed in our factories. Built up
sections are made from these plates in automatic beam
welding line by submerged Arc welding (SAW).
Secondary Members used in PEB include purlines, side
runners, eave struts, fascia channels, door, window,
rafters stays, bracings etc.
Purlines and girts are cold rolled formed light gage Z
sections varying in depth from 180 to 300 mm and in
thickness from 1.5 mm to 2.5 mm as per design
All primary connection fasteners will be with high
strength bolts conforming to the physical specification to
the ASTM A325 or equalent.
The fasteners for the cladding / roofing includes GI self
tapping screws/ GI Self drilling screws in varying sizes
to suit the roofing / cladding requirements. These
accompanied with neoprene or EPDM washers to obtain long
services and maximum weather resistance.
