Manufacturing of Pre-Engineered Buildings
Our customers choose pre-engineered steel buildings (PEB) over other types of construction for the following reasons:
1- Value :
Pre-engineered steel structures require a lower initial investment, lower maintenance cost once completed, and are environmentally friendly as all materials can be recycled.
2- Strength :
Our structures are designed and built to withstand severe weather conditions (wind, snow, rain) and even earthquakes.
3- Flexibility :
Large, clear spans allow our customers to house almost any type of business comfortably and efficiently, as well as to expand and change their setup whenever they desire.
Other Distinct Advantages :
Include quick construction time and capacity for design flexibility – allowing our engineers to create a unique, and attractive appearance that fits the distinctive business image of each customer. Quality Leaders Factory buildings accommodate a wide variety of occupants, from factories and showrooms to shopping malls and hypermarkets.

Basic Building Parameters :
Pre-engineered buildings are defined by the following basic parameters: Building Width, Length, Height, Roof Slope, End Bay Length, Interior Bay Length and Design Loads.
1- Building Length :
Building length is the distance between the outside flanges of endwall columns in opposite endwalls. It is a combination of several bay lengths.
2- Building Height :
Building height 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.
3- Building Width :
This is the angle of the roof with respect to the horizontal. The most common roof slopes are 0.5/10 and 1/10. Any practical roof slope is possible.
4- Roof Slope (x/10) :
No matter what primary framing system is used, the building width is defined as the distance from outside of eave strut of one sidewall to outside of eave strut of the opposite sidewall.
5- End Bay Length :
This is the distance from the outside of the outer flange of endwall columns to the center line of the first interior frame column.
Basic Building Parameters :
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, Quality Leaders Factory Pre-Engineered Buildings are designed for the following minimum loads:
1- Roof Live Load: 0.57 kN/m2
2- 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.
Primary Framing Systems :
Pre-Engineered Buildings are constructed using a 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.
Structural Subsystems :
This section contains few subsystem examples of actual Pre-Engineered Buildings, along with simple sketches of some of their structural configurations. For complete and detailed information, please refer to the Technical Manual for Pre-Engineered Buildings.
Structural Subsystems :
Building Accessories :
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 fit almost any of your requirements. Here are a few examples, as they appear in existing buildings.
Crane System :
For buildings that require a crane system, Quality Leaders Factory supplies the column or rafter brackets. The crane runway beams for top- running and under-running crane systems will be supplied by Quality Leaders Factory. 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.
Mezzanine System :
The standard Quality Leaders Factory mezzanine framing system consists of a steel deck supported by joists framed onto 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 affect the economy of a mezzanine system.
Our Quality Leaders Factory representative nearest to you can help you to 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 main frame 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 for these requirements available to our Quality Leaders Factory representative nearest to you at the time of quotation.
