Pre-engineered buildings (PEBs) are gaining popularity in India today. They are strong, fast to build, and cost-effective. But do you know what materials make these buildings so reliable?
In this blog by Shobha Globs, a trusted Pre-engineered Building Manufacturer in India, let’s explore the main materials used in pre-engineered buildings and why they are chosen.
What is a Pre-engineered Building?
A pre-engineered building is a steel structure designed and built using a factory-made approach. All components are fabricated in the factory and then assembled on-site using bolts. This method saves time and ensures strong, durable construction.
Main Materials Used in Pre-engineered Buildings
Here are the key materials that make PEBs strong and long-lasting:
1. Structural Steel
Steel is the backbone of every PEB. It forms the main frame of the building.
Types of Structural Steel:
Hot-Rolled Sections: Are used for heavy columns and beams.
Built-up Sections: Made by welding steel plates, commonly used for rafters and columns.
Cold-formed Sections: Used for lighter secondary members like purlins and girts.
Why Use Structural Steel?
High strength with less weight
Easy to fabricate and install
Long-lasting and recyclable
2. Purlins and Girts
These are secondary members that support the roof and wall panels.
Materials Used:
Cold-formed Z and C sections made from galvanized or mild steel.
Benefits:
Lightweight but strong
Easy to handle
Cost-effective for large spans
3. Roof and Wall Cladding
Cladding protects the building from the weather and adds to its appearance.
Materials for Cladding:
Galvanized Iron Sheets (GI): Coated with zinc to prevent rusting.
Color Coated Sheets: Pre-painted sheets for durability and aesthetics.
Aluminium Sheets: Lightweight and corrosion-resistant, used for special projects.
Thickness:
Generally ranges between 0.35 mm to 0.50 mm, based on design needs.
4. Insulation Materials
Insulation is used to control the temperature inside the building.
Common Insulation Materials:
Glass Wool or Rock Wool: For thermal and sound insulation.
PUF Panels (Polyurethane Foam Panels): Excellent thermal insulation, used in cold storage.
EPS Panels (Expanded Polystyrene): Affordable option for basic insulation needs.
5. Fasteners and Bolts
Fasteners hold the entire building together.
Materials Used:
High tensile bolts (Grade 8.8 or 10.9): For strong connections.
Galvanized bolts and screws: Prevent rusting, especially in roofs and walls.
6. Paints and Coatings
Paints and coatings protect steel from rust and weather effects.
Types of Coatings:
Primer Coating: Zinc-rich primers for steel protection.
Finish Paint: Polyurethane paints for UV and weather resistance.
Galvanization: For purlins and sheets to prevent corrosion.
7. Accessories and Other Materials
PEBs also include:
Skylights: Transparent sheets for natural lighting.
Ventilators: For airflow and temperature control.
Louvers: For ventilation on walls.
Gutters and Downspouts: To channel rainwater properly.
Why These Materials Are Preferred
Here’s why these materials are chosen by any reliable Pre-engineered
Building Manufacturer in India like Shobha Globs:
Strength with less weight: Steel provides high load capacity.
Faster construction: Factory fabrication saves time on-site.
Long life: Galvanized and coated materials prevent rust.
Flexibility: Easy to expand or modify in future.
Cost-effective: Reduced labor costs and wastage.
Environment-friendly: Steel is recyclable and reusable.
Standards Followed by Pre-engineered Building Manufacturers in India
Trusted manufacturers like Shobha Globs follow strict quality standards such as:
IS 2062: For structural steel
IS 801: For cold-formed light gauge steel
IS 875: For structural loads
IS 513: For cold-rolled steel sheets
Choosing the Right Materials for Your PEB
Here are some tips to select materials wisely:
Check load requirements before finalizing steel grades.
Choose cladding thickness based on location and weather conditions.
Use insulated panels if temperature control is important.
Ensure all fasteners are galvanized to avoid rust.
Common Mistakes to Avoid
Using low-quality steel to save money compromises safety.
Skipping insulation in hot or cold areas.
Using non-galvanized fasteners – they rust quickly.
Not applying proper coatings to steel frames.
Final Thoughts
The right materials are the key to strong and long-lasting pre-engineered buildings. From structural steel to cladding and fasteners, each material plays an important role in making your project successful.
