Types of Steel Girders: A Guide by National Power Engineering Company (NPEC) Siliguri

Steel girders play a crucial role in modern construction, providing strength and stability for bridges, buildings, and industrial structures. At National Power Engineering Company (NPEC) Siliguri, we specialize in high-quality steel fabrication, ensuring durable and efficient solutions for various engineering projects. Here, we explore different types of steel girders and their applications.

1. I-Beam Girders

I-Beam girders, also known as H-beams or Universal Beams, are widely used due to their high strength-to-weight ratio. They are commonly found in:

• Bridges
• Industrial buildings
• Heavy load-bearing structures

Advantages:

• High structural integrity
• Efficient load distribution
• Cost-effective in large-scale projects

2. Box Girders

Box girders consist of two or more vertical steel plates joined by horizontal flanges, forming a box-like shape. These girders are typically used in:

• Long-span bridges
• Railway bridges
• Highways and flyovers

Benefits:

• Excellent torsional resistance
• Suitable for heavy loads and long spans
• Minimal maintenance requirements

3. Plate Girders

A plate girder is made by welding or bolting steel plates together to form a deep and strong beam. NPEC Siliguri manufactures precision-engineered plate girders ideal for:

• Large infrastructure projects
• Industrial sheds
• Heavy machinery support systems

Key Features:

• Customizable for specific load conditions
• Suitable for large spans
• Highly durable and resistant to bending

4. Truss Girders

Truss girders consist of a series of interconnected triangles, making them lightweight yet highly robust. These are widely used in:

• Roof structures
• Pedestrian bridges
• Airport terminals

Advantages:

• Reduced material usage
• High strength-to-weight ratio
• Aesthetic and architectural flexibility
