GI Pipe Weight Chart 2026: Complete Guide to GI Pipe Weights

The GI Pipe Weight Chart 2026 is an essential reference for engineers, contractors, fabricators, architects, procurement professionals, and buyers. GI pipes are widely used in construction, plumbing, water supply, agriculture, infrastructure, and industrial applications. The weight of a GI pipe depends mainly on its nominal size, outside diameter, wall thickness, and pipe class. As the diameter and wall thickness increase, the weight per meter generally increases as well. A GI Pipe Weight Chart provides approximate weight values in kilograms per meter for different pipe sizes. Class A, Class B, and Class C GI pipes can have different wall thicknesses and corresponding weights. Class A pipes are generally associated with lighter-duty requirements and lower material weight. Class B GI pipes are commonly used for plumbing, water supply, construction, and general engineering applications. Class C pipes are generally heavier and may be selected for applications requiring greater wall thickness. GI pipe weight can be calculated by multiplying the weight per meter by the total required pipe length. For theoretical calculations, the formula Weight (kg/m) = 0.02466 × WT × (OD − WT) can be used. Here, OD represents outside diameter in millimetres and WT represents wall thickness in millimetres. The actual supplied weight may vary because of manufacturing tolerances and the zinc coating applied during galvanizing. GI pipe weight information is useful for material estimation, transportation planning, storage, lifting, and structural load calculations. It also helps procurement teams compare supplier quotations based on weight, meter length, specifications, and applicable pricing. GI pipe prices may be quoted per kilogram, per meter, or per pipe length depending on the supplier and specification. The final price can vary according to steel market conditions, pipe size, wall thickness, zinc coating, quantity, GST, freight, and delivery location. Before purchasing, buyers should confirm the nominal size, outside diameter, wall thickness, class, standard, quantity, and manufacturer specifications. Using a reliable GI Pipe Weight Chart helps reduce estimation errors and improves project planning and procurement efficiency. For accurate purchasing, the chart values should be verified with the manufacturer's technical documentation and current commercial quotation.
