Pre-engineered buildings (PEBs) are a construction method that’s widely gaining popularity worldwide. The PEB market showcased a remarkable growth rate of 12 percent in the year 2020. A pre-engineered building differs from the traditional one. Still, it can provide custom functionalities and innovative architectural design in a much shorter time. The PEB method leads to the construction of low-rise, energy-efficient buildings that are ideal for commercial purposes. In this article, you’ll learn about the significant components of such a structure, its benefits, and use cases.
Main Components of a Pre-Engineered Building
The primary components of this type of structure include the mainframe, column, and rafters. You can know more about them below.
The mainframe consists of the tough steel frames of the structure. The pre-engineered steel building’s rigid frame constitutes tapered columns and rafters. The flanges are linked to webs through the medium of an unbroken fillet weld on aside.
The primary purpose of the columns in a pre-engineered building structure is to shift the vertical weight to the foundations. In PEBs, the columns are constructed of I sections. These are quite cost-effective than others. The width and breadth increase continuously from the bottom to the topmost part of the column.
It is one part of a sequence of sloped structural beams that go on from the ridge to the wall-plate, downslope perimeter and is engineered to assist the roof deck. The rafter also supports the loads associated with the roof deck.
Secondary components of pre-engineered buildings
The secondary components of a PEB structure comprise Purlins and Grits, Eave Struts, Bracings, Claddings, and Accessories.
- Purlins and Grits – Purlins are utilized on the roof, while grits are employed on the walls. Purlins and Grits are cold-formed sections. They have stiffened flanges.
- Eave struts – They are employed where the sidewall and the roof intersect. They are unequal flange sections with a 200 mm depth and a 104 mm wide top flange. Every flange consists of a stiffener lip with a length of 24 mm.
- Bracings – It’s a basic member that contributes to the building stability against impact in a longitudinal way like cranes, wind, and earthquakes.
- Cladding – Cladding in the pre-engineered building construction is made out of a base metal, which can be either aluminum or Galvalume coated steel. The aluminum should conform to ASTM B 209M (cold-rolled steel), and the Galvalume coated steel should conform to ASTM A 792M/345B.
- Accessories – Accessories include bolts, skylights, doors and windows, turbo ventilators, and other non-structural building parts.
Advantages of Pre-Engineered Building
A PEB is a highly versatile structure. Architects can effortlessly set up, modify, extend, and transport them to varied areas. These buildings are safe for the environment, and you can make them visually pleasing by integrating unique functionalities. Moreover, the PEB construction methodology is 20 to 30 percent more cost-effective than traditional building methodologies.
Quality and durability
A PEB gets pre-fabricated in a highly controlled environment. It makes them more long-lasting and of high quality. When installed correctly, a PEB roof lasts for a much longer time. A PEB roof is erected when the clips attached to the steel connect to the roof. A piece of equipment secures the top to the clips, enabling them to contract and expand. It leads to the creation of a durable roof that can withstand the roughest wind conditions.
A pre-engineered building structure brings much cost-efficiency. A simple cost-saving example is the employment of a basic seam roof in contrast to the membrane-style roof of conventional buildings. Remember that the savings you’ll gain from PEBs will be dependent on the extent of your project. Another factor that drives down the expenses is the usage of sheeting. You can earn more cost efficiencies from your project when you consult with your architectural and construction firm and comprehend your local market. You’ll also understand the conditions that will influence the option of a roofing system for your pre-engineered structure.
It saves a lot of time.
In PEB construction, the design and material get selected beforehand. It results in the setting up of the facility much more quickly and efficiently. You can get a PEB delivered to you in a span of a couple of weeks. This building construction style minimizes the overall building time of projects by 50 percent. It results in quicker occupancy and kickstarts the process of revenue realization.
The benefit of low maintenance
The maintenance of a PEB is exceptionally low. They optimally consume resources and use technology to the utmost. Such buildings keep up their appearance throughout their lifespan as they have very high quality. Steel is resistant to corrosion and rust. It develops a solid foundation, which is almost free of maintenance for a very long time. This need for not maintaining it is another factor that makes it score over conventional buildings everywhere. Additionally, the minimal environmental impact of these buildings makes them perfect for those who want their project to be sustainable.
What are the Use Cases of Pre-engineered Building?
Almost any kind of building can be built with the pre-engineering methodology. Its most general applications are institutional, commercial, and industrial buildings. They get heavily employed in the construction of industrial sheds and warehouses. Recently, the PEB method is also finding applications in many rural, urban mass, and individual housing projects.
You can employ a pre-engineered steel building for building the following:
- Office buildings
- Aircraft hangers
- Indoor and outdoor sports hall
- Railway stations
- Labor camps
- Community centers
- Petrol pumps.
Technological enhancements over the decades have significantly improved people’s quality of life. A key revolution has been that of the pre-engineered building. As technology continues to develop at a rapid pace, the PEB concept is expanding as well. Moreover, in many countries, the steel structures market is growing at an unprecedented pace. It accounts for a bright future of various pre-engineered steel building projects.
