peb structures
Pre-Engineered Buildings (PEBs) are structures designed and fabricated in a factory before being shipped to the construction site for assembly. These buildings are primarily made of steel but can also incorporate materials such as aluminum or concrete.
Advantages of PEBs
- Faster Construction Time – PEBs are constructed more quickly than traditional buildings, making them ideal for businesses requiring rapid facility setup.
- Cost-Effective – The mass production of components in a factory and the efficient assembly process reduce overall costs.
- High Quality – Manufactured in a controlled environment, ensuring superior quality and precision.
- Durability – PEBs can withstand various weather conditions and require minimal maintenance.
- Flexibility – PEBs can be customized for diverse applications, including warehouses, factories, office buildings, retail stores, and more.
- Ease of Expansion – Bolt-together systems allow for quick modifications and expansions.
Common Applications of PEBs
PEBs are used in:
- Warehouses
- Factories
- Office Buildings
- Retail Stores
- Aircraft Hangars
- Sports Arenas
- Concert Halls
- Schools
- Hospitals
- Shopping Malls
- Airports
- Railway Stations
- Power Plants
- Oil and Gas Facilities
Components of PEBs
1. Main Frame Steel Column
- Typically a tapered I-section, optimizing steel usage while maintaining strength.
- Provides high strength-to-weight ratio and reduced material costs.
- Prefabricated and bolted together at the site for faster construction.
- Made from high-yield strength steel such as A36 or A572.
2. Girts (Purlins)
- Horizontal structural members attached to main frame columns.
- Made of cold-formed steel, commonly in Z-section but also available in C and L-sections.
- Support exterior wall panels, windows, doors, and roofing panels.
- Spaced between 1200 mm to 1500 mm, depending on the structure’s requirements.
- Contribute to structural integrity by resisting wind and seismic loads.
3. Bracing System
Provides resistance against lateral forces (wind and earthquake loads).
Common types:
- Cross Bracing – Highly effective but reduces usable space.
- Chevron Bracing – Space-efficient but less effective.
- K-Bracing – More effective than Chevron but takes up more space.
- Installed at end bays, roof levels, and at intervals along the building.
4. Transparent Sheet Panel
- Polycarbonate sheets are commonly used due to:
- High light transmission (up to 92%) for natural lighting.
- Durability against weather, impact, chemicals, and UV rays.
- Lightweight and easy installation.
- Used for skylights, sidelights, curtain walls, and partitions.
5. Wall Cladding & Roof Sheet
Powder-coated sheets provide corrosion resistance, durability, and aesthetics.
Features:
- Factory-applied polyester paint (0.5 mm thick).
- Available in multiple colors and finishes.
- Lightweight and easy to install.
- Provides up to 1-meter coverage and 12-meter shipping length.
6. Rolling Shutters
- Ideal for security, durability, and ease of operation.
- Common materials: Steel, aluminum, and polycarbonate.
- Used for warehouses, factories, and commercial buildings.
Conclusion
Pre-Engineered Buildings (PEBs) offer an efficient, cost-effective, and durable construction solution for various industries. Their ability to be customized, quickly constructed, and expanded makes them an excellent choice for modern infrastructure development.
