Pre Engineered Buildings (PEBs) are the most economical , effective, easiest and widely preferred architectural building construction system. The pre-engineered metal building system is a large column free building enclosure system that always includes a structural system and often includes roof and wall cladding. The general idea of the system is represented in the diagram below.

Vera’s PEBs are custom-engineered to specific dimensions, structural criteria and materials in accordance with customer’s requirements and local building codes. Each part of the system is designed to precisely fit together which transforms into buildings that can be built with greater speed and accuracy than is possible using conventional methods.

Vera’s PEBs also propose substantial cost and performance benefits over conventional construction methods including lower life cycle costs for greater return on investment, unlimited design flexibility and sustainability attributes such as 100% recycled steel, superior thermal building envelopes and much more. The production line is highly sophisticated, having Auto welders, multi-cutting torches, shear cutting machines etc., which greatly reduce the time of fabrication of built-up components.




Due to the use of high strength steel, tapered built-up sections and continuous light gage secondary steel section, there is an overall reduction in steel weight, construction cost and production time. The components are engineered beforehand and standardized, which reduces the engineering, production and erection time. Use of customized software, standard dimensions and standard accessories increases the speed of the project. Buildings are typically delivered in just a few weeks after approval of drawings. Foundation and Anchor Bolts are cast in parallel with manufacture of the building. Site assembly is fast, as all building components are delivered finished, ready for site bolting. It can reduce total construction time on a project by at least 50%. This will allow faster occupancy and earlier realization of revenue.


Flexibility of Expansion

Buildings can be easily expanded in length by adding additional bays. Also, expansion in width and height is possible by pre-designing for future expansion.


Lower Cost

Due to the systems approach, there is a significant saving in design, manufacturing and site erection cost. The structural elements are shaped to follow the stress diagram of the member, thus reducing weight, cost and load to foundations. The secondary members and cladding nest together reduces transportation cost.


Low Maintenance

Buildings are supplied with high quality paint systems for cladding and steel to suit ambient conditions at site, which results in long durability and low maintenance costs.


Architectural Versatility

Buildings can be supplied with various types of fascias, canopies, and curved eaves and designed to receive pre-cast concrete wall panels, curtain walls, block walls and other wall systems.



The low-weight exible frames oer higher resistance to seismic forces.


Quality Control

As buildings are manufactured completely in the factory under controlled conditions, the quality is assured.


Architectural Versatility

Buildings can be supplied with various types of fascias, canopies, and curved eaves and designed to receive pre-cast concrete wall panels, curtain walls, block walls and other wall systems.


Pre-engineered buildings are defined by the following basic parameters: Building Width, Length, Height, Roof Slope and End Bay length and Design Loads.

  • BUILDING LENGTH : It is the distance between the outside flanges of end wall columns in opposite and walls. It is a combination of several bay lengths.
  • BUILDING HEIGHT : It is the eave height, which is usually the distance from the bottom of the main frame column base plate to the top outer point of the eave strut. When columns are recessed or elevated from the finished floor, eave height is the distance from the finished floor level to the top of the eave strut.
  • BUILDING WIDTH : No matter what primary framing system is used , the building width is defined as the distance from outside of eave strut of one side wall to outside of eave strut of the opposite side wall.
  • ROOF SLOPE (X/10) : This is the angle of the roof with respect to the horizontal. The most common roof slopes should not be less than 0.5/10. Any practical roof slope is possible.
  • END BAY LENGTH : This is the distance from the outside of the outer ange od end wall columns to the center line of the first interior frame column.
  • INTERIOR BAY LENGTH : This is the distance between the center lines of two adjacent interior main frame columns. The most common bay lengths are 6, 7.5 and 9 meters. Any bay length is possible up to 15 meters.
  • DESIGN LOADS : Unless otherwise specified, FBSL Pre-Engineered Buildings are designed for the following minimum loads. Roof Live Load : 0.57 KN/M2, Design Wind Speed : 110 KM/H

Design parameters of snow loads, earthquake loads, collateral loads, crane loads or any other loading condition must be specified when requesting a quotation. Loads are applied in accordance with American codes and standards applicable to pre-engineered buildings unless otherwise requested at the time of quotation.


Vera Pre- Engineered Buildings are constructed using variety of framing systems. The diagrams on this page illustrate those most commonly employed. They are symmetrical at the ridge line. Asymmetrical and non-equal Multi-span Framing Systems are also available. Please consult with your Vera representative nearest to you about your specific project requirements.


For buildings that require a crane system, Vera supplies the column or rafter brackets. The crane runway beams for top-running and under hung crane systems will be supplied by Vera. For mono-rail crane systems the runaway beam is supplied by the crane supplier. The customer needs to supply complete crane system details, data and supplier name, for the accurate design and estimation of all crane supporting buildings.


The standard Vera Mezzanine framing systems consists of a steel deck supported by joists framed on to main mezzanine beams. The main beams may also be supported by intermediate columns if dictated by design loads. The top flange of the joists fits immediately below the top flange of the primary beams. Applied floor loads, such as dead, live and collateral loads along with mezzanine column spacing, can determine the most economical mezzanine design and column spacing for your project.

Unless otherwise specified, the primary mezzanine beams should run across the width of the building parallel to the mainframe rafters. Joists should run parallel to the roof purlins along the length of the building. Multi-level mezzanines, including features such as interior equipment platforms, catwalks, floor openings and staircases are also available. It is important to make the data of these requirements available to our Vera representative nearest to you at the time of quotation.


  • Primary Built up Members (Minimum Yield strength is 34.5 KN AM2) : High grade steel plates conforming to ASTM A 572M Grade 345. Factory painted with a minimum of 35 microns (DFT) of corrosion protection primer
  • Secondary Members (Minimum Yield strength is 34.5 KN CM2) : High grade steel plates conforming to ASTM A 605 Grade 50 or equivalent, available in 1.5mm, 1.75 mm, 2.0 mm, 2.25 mm, 3.0 mm thickness.


Vera offers customers a variety of standard trims that provide a seamless finished looks and style to the cladding of their pre-engineered buildings. The most commonly used are illustrated below. Trims are made from the same materials as standard and available in all standard panel colors.


Vera Pre- Engineered Buildings can be designed with your choice of a variety of attractive and architecturally sound accessory options. Windows, doors, natural lighting and ventilation accessories are available to at almost any of your requirements.
