Introduction

Pre-Engineered Buildings (PEBs) are a contemporary method of construction where the entire building is designed, fabricated, and assembled using pre-manufactured components. These structures are engineered at a factory and then assembled at the construction site, offering a fast, flexible, and cost-effective alternative to conventional building methods. PEBs are widely used in industrial, commercial, and institutional sectors due to their efficiency and durability.

Key Characteristics

• Factory-Fabricated Components: All structural elements are made off-site.
• Custom Engineering: Designed to meet specific load conditions, climate, and usage requirements.
• Bolt-Together Assembly: On-site erection involves bolting or welding prefabricated parts, minimizing construction time.
• Lightweight & Strong: Utilizes high-strength steel, reducing weight without compromising structural integrity.

Components of a PEB

1. Primary Framing: Main load-bearing elements like columns and rafters.
2. Secondary Framing: Purlins, girts, and bracings for added support.
3. Roof & Wall Panels: Made from metal sheets or insulated sandwich panels.
4. Accessories: Doors, windows, ventilation systems, skylights, etc.

5. Foundation: Typically a concrete base, prepared before the building is delivered.
