Steel Building Benifit

6
Pre-engineered buildings (PEBs) use a predetermined
inventory of raw materials that has
proven over time to satisfy a wide range of structural
and aesthetic design requirements. This flexibility
allows PEBs to fulfill an almost unlimited range of
building configurations, custom designs,
requirements and applications.
A pre-engineered steel building is a building shell
utilizing three distinct product categories:
• Built-up “I” shaped primary structural framing
members (columns and rafters)
• Cold-formed “Z” and “C” shaped secondary
structural members (roof purlin, eave struts and
wall girts)
• Roll formed profiled sheeting (roof and wall
panels)
Optional structural subsystems are widely
incorporated into pre-engineered buildings and
provide functional as well as aesthetic features.

Functional subsystems include mezzanine floors
(including joists and decking), crane runway
beams (to support crane systems), roof platforms,
catwalks, etc.
Aesthetic features include fascias, parapets,
canopies and roof extensions.
Until 1990, the use of pre-engineered buildings was
confined mostly to North America and the Middle
East. Since then, the use of pre-engineered buildings
has spread throughout Asia and Africa where the
PEB construction concept has now been widely
accepted and praised.
A growing number of prominent international
contractors and designers, who previously specified
conventional structural steel buildings exclusively,
have recently converted to the pre-engineered
building approach. They now enjoy significant cost
savings and benefits from the faster construction
cycle resulting from this concept.
