Manufacturer of Girder Fabrication in Kolkata

A girder is a large, deep support beam used as the main horizontal structural element in construction — carrying and supporting smaller beams above it. Girders are typically capable of longer spans and greater load capacity than standard beams, making them essential in bridge construction and heavy industrial structures.

Girders commonly have an I-beam cross-section, made up of two load-bearing flanges separated by a stabilizing web, though they can also be fabricated in box, Z, or other structural shapes. A girt is a vertically aligned girder used specifically to resist shear loads.

Smaller steel girders are rolled into shape, while larger girders — 1 metre (3 feet) deep or more — are manufactured as plate girders, welded or bolted together from individual steel plates. Nony Industries fabricates both rolled and plate girders to project-specific load and span requirements.
