The enlargement of PEB is Pre-Engineered Building, commonly known as prefabricated building, informally a prefab building, is a type of building that consists of several factory-built components or units that are assembled on-site to complete the unit. Buildings have been built in one place and reassembled in another is the core concept of Pre-Engineered Building.

Benefits of PEB

PEB has wide variety advantages. Here given below some advantages of PEB structure:-

PEB Structural Components


Cosmic fabricate primary beam from high grade steel plate conforming to ASTM A572, Grade 345 Type 1 or Equivalent with a minimum yield strength of 34.5Kn/ and are factory painted, with a minimum of 35 microns (DFT) of red oxide primer/zinc cromate primer.


Purlins are secondary members of steel structures. Cosmic has high strength galvanized steel purlin available in 1.6 mm, 1.8 mm, 2.0 mm and 2.5 mm thickness, conforming to ASTM A 607 grade 50 (or equivalent)

Factory painted, with a minimum of 35 microns (DFT) of red oxide primer, in case of mild steel purlin.


Cable bracing is a secondary member. It ensures the stability of the building against forces in the longitudinal direction due to wind, cranes, earth quake, etc. Cables are made of galvanized extra high strength seven strand cable of 12 mm diameter confirming to ASTM A572-class 1 (G50).

PEB Terminology

Building Terminology

Anchor Bolts : Bolts are used to anchor structural member to a concrete floor, foundation or other masonry support. Term generally refers to bolts that secure columns and jambs to the concrete slabs.

Base Plate : A shop welded, pre-punched plate on that portion of a structural column that rests on the concrete foundation and is secured by anchor bolts.

Bay (End) : The distance between the centerline of the first interior frame and the outside of the end wall structure.

Bay (Interior) : The space between frame center lines in the lengthwise direction of the building.

Bent Plate : A plate bent to form an angle.

Brace Rods: Rods used on roof and sidewall of some buildings to transfer wind, seismic and lateral crane force to the foundation.

Building Length : The distance between the out flanges of the girt of two end walls.

Building Width : The distance between the outside of eave struts of two long sidewalls.

Building Height: This is the eave height which is the length form the foot of the rigid frame column bottom to the top outer point of the eave strut.

Built- up Section: A structural member, usually an “I” shape, made from individual web and flange flat plates by welding them together.

“C” Section: A member cold formed from steel coil in the shape of a “C” used primarily in bearing frame end walls and framed opening.

Canopy: Any overhanging or projecting structure with its extreme end unsupported.

Clear Span: The distance or clear and unobstructed opening between two supports of a beam, when used with a ridge frame, this is generally less than the nominal building width.

Column: A primary structural member used in a vertical position to transfer loads from roof beams, rafters to the foundation.

PEB Parameters

Basic Building Parameters

Eave Canopy : A roof extension beyond the sidewall of a building.

Eave Canopy : A roof extension beyond the sidewall of a building.

Eave Fasica: Trim used to close off the top of sidewall panels in lieu of Eave gutter or eave trim.

Eave Height: The vertical dimension from finished floor to top of eave struts.

Eave Strut: A structural member located at the eave, used for supporting the roof and wall panels.

Gable: The triangular portion of the end wall of a building, directly under the sloping roof and above the eave line.

Girder: A main horizontal or near horizontal structural member that supports vertical loads.

Girt: Wall beams supporting wall cladding.

Purlin: A horizontal secondary structural member bolted to rafter to support roof load.

Gutter: Per-formed light gauge metal sheet channel at the roof, along the side wall or in the valleys used to collect rain water from the roof.

Mezzanine: An elevated floor system inside the building and above the ground floor, most commonly used for office or storage purpose.

Beam: Support loads normal to its axis.

Main Beam: Usually indicates a major beam that supports small beams.

Sub Beam: Closely spaced beams supporting floors/roofs.

Jack Beam: A primary horizontal member used to support another beam, truss or rafter.

Spandrel Beam: Beam around the perimeter of the floor.

Rafter: Roof beams supported by column.
