Pre-engineered buildings: Components, pros and cons

Pre engineered buildings, also known as PEBs, are created using a single design by a PEB supplier or PEB manufacturer and are constructed utilising various materials and fabrication techniques to meet multiple structural and aesthetic design specifications. A pre-engineered building is constructed of parts produced in a factory and assembled at a specific location.

Pre-engineered structures are often made of steel and can serve as an alternative to traditional structural steel buildings. The manufacturer precisely sizes the components before being brought to the site and assembled. Bolted connectors make up their construction. They are mostly utilised to increase:

1. The system of structural steel framing
2. System of metal roofing
3. Various materials for wall panels

Engineers consider a clear span between bearing points, roof slope, live loads, dead loads, wind uplift, and many other factors while designing a pre-engineered building. These structures may be modified to fit a variety of structural needs. It may result in a structural framework saving. Pre-engineered buildings are becoming more and more common in the modern world since they perform better than traditional buildings in terms of cost savings and construction benefits.

Pre-engineered buildings: Components

The principal elements of PEB are classified into many kinds, including:

Vertical columns or main framing

The mainframes are steel, rigid frames that support the structure. Tapered columns and tapered rafters make rigid steel frames. When the flanges are welded, they are constructed with cutting-edge technology.

End wall framing

This serves as the stiff primary structure. The columns that make up the end wall framing system have pinned ends. End wall rafters support the horizontal rafters.

The PEB’s secondary cold-formed parts are purlins, girts, and eave struts. There is no need for welding in this preparation. The steel coil is prepared by being welded into the correct shape. Purlins and girts are made in the Z-shape, whereas eave struts are in the C-shape.

Crane system

By minimising forklift traffic, crane systems increase material handling productivity and enable better space use. The built-up portions with cap channels support the crane’s runway beams.

Insulation and sheeting

Steel sheets are typically formed of galvanised profile sheets with a permanent colour coating. Moreover, specific coatings are applied to sheets to improve their anti-corrosion qualities. They are insulated using insulation slabs, and roofing steel sheets are then attached on top of it.

Mezzanine system

The primary mezzanine beams of the mezzanine system are framed into black joists that support a black deck.

Coatings and paints

Preparation of the surface before painting and paint curing on a fully automated line under ideal circumstances to manufacture pre-painted steel on current high-speed coil painting lines.

Pre-engineered buildings: Benefits

Pre-engineered structures offer several benefits, and these benefits speed up construction. The many benefits are as follows:

1. Pre-engineered structures are constructed from a preset stock of raw materials. Many structural and cosmetic criteria have been met by it. The parts have been previously developed and are standardised. The usage of specialised design and drawing software slows down the speed of the project.
2. Due to its use of standardised pieces and connections, PEBs need less time to design.
3. Flexible, low-weight frames are more resistant to earthquake forces.
4. The systems approach has made it possible to reduce the cost of design, manufacture, and site construction. The form of the structural diagrams is such that they adhere to the stress diagram, lowering the price, weight, and load on the foundations.
5. Pre-engineered buildings weigh between 30% and 35% less than traditional steel constructions. PEB’s underlying structures are straightforward designs that are simple to assemble using lightweight materials.
6. When it comes to PEB, adding more bays to the structures makes it simple to lengthen them. If you plan for future extensions, expanding in width and height is feasible.
7. All of the connections utilised in a PEB are standard, which reduces the erection time.
8. As the structures are entirely constructed in a factory under regulated conditions, quality control in the case of PEB is guaranteed.
9. High-quality paint methods are used on steel and cladding to match the site’s environmental conditions. Long durability and cheap maintenance costs are the results of this.
10. One manufacturer provides the entire building kit for the PEB. As a result, the compatibility of the building materials can be completely guaranteed.
11. PEB can withstand even the strongest storms. It is the most resilient. The finest industry warranties are included with these structures.

Pre-engineered buildings: Disadvantages

1. It may be prone to corrosion if not taken care of correctly.
2. Despite being a powerful conductor of heat, steel reduces a building’s thermal comfort.
3. Due to its conductivity, this structure is more prone to fire and damage.

Why are pre-engineered buildings a game-changer for the construction industry?

A larger category of prefabricated structures, known as “PEB frameworks,” is when structural elements like walls and floors are manufactured off-site and transported to the construction site. The finished pieces of your construction are now visible and ready for assembly. This misunderstanding is the root of the prevalent misperception that this architectural style necessitates the construction of cheap, transient buildings. Let’s examine the qualities it offers and how it will alter the future by addressing the increasing need for space in the world.

Time saver

When compared to creating a traditional structure, time is saved, which may lead to quick delivery. Projects may be finished on schedule because PEBs can be finished faster using specialist software. In some circumstances, a building delivery must be finished quickly. Thus, PEBs are the best material to employ in such projects.

Economic approach

If you’re on a low budget yet want the greatest design and aesthetics, PEB construction is the solution. Because the majority of its components are manufactured in factories, PEBs allow you to save money. The costs of starting from scratch on a building site while employing the conventional building approach are passed on to the client.

Simple to alter

PEBs may be made to match a project’s unique requirements and available space. Choose from various metal building components to tailor the usefulness of your prefabricated construction.

Durable

PEBs are the most dependable option for protection against hazardous weather since they resist lightning and thunder. Heavy winds, severe snowfall, sandstorms, and downpours have little effect on them. People worldwide may profit from PEB buildings since they are impervious to lightning and thunderstorms.

Protection against earthquakes

Pre-engineered structures offer protection against earthquakes since they are made to withstand shocks up to a specific magnitude without collapsing. It is the preferred building material where earthquakes are expected to occur.
