GI Pipe Weight Chart 2026 – Class A, B, C Kg/m + PDF

Last Updated: September 2026

The GI Pipe Weight Chart 2026 is a useful reference for engineers, contractors, fabricators, architects, procurement professionals, and steel buyers who need accurate information about galvanized iron pipe weight per meter. GI pipe weight is important for material estimation, transportation planning, structural calculations, purchasing, inventory management, and project cost estimation.

GI pipes are available in different nominal sizes, outside diameters, wall thicknesses, and classes. As diameter and wall thickness increase, the weight per metre generally increases. A reliable GI pipe weight chart in kg/m helps users estimate the quantity and approximate weight required for a project.

GI Pipe Price Per Kg & Per Meter 2026

GI pipe prices depend on size, wall thickness, class, manufacturer, zinc coating, order quantity, steel market conditions, GST, freight, and delivery location. Pipes may be quoted per kilogram, metre, or length.

For estimation, an indicative GI pipe price range of ₹65–₹82 per kg can be used. Approximate price per metre can be calculated by multiplying Class B weight per metre by the applicable price per kilogram.

What Is a GI Pipe Weight Chart?

A GI Pipe Weight Chart shows the approximate weight of galvanised iron pipes according to nominal size, outside diameter, wall thickness, pipe class, and weight per metre. Weight is generally expressed in kilograms per metre (kg/m).

For example, if a GI pipe weighs 7.35 kg/m and 100 metres are required:

7.35 × 100 = 735 kg

Therefore, the estimated total pipe weight is approximately 735 kg.

GI Pipe Weight Calculation Formula

The theoretical weight of a steel pipe can be estimated using:

Weight (kg/m) = 0.02466 × WT × (OD − WT)

Where:

OD = Outside Diameter in mm

WT = Wall Thickness in mm

0.02466 = Steel density conversion constant

This formula provides a theoretical estimate. Actual GI pipe weight may vary because of manufacturing tolerances and zinc coating.

Total GI Pipe Weight

Total Pipe Weight = Weight Per Meter × Total Pipe Length

For example, if the pipe weighs 8 kg/m and the required quantity is 1,000 metres:

8 × 1,000 = 8,000 kg = 8 tonnes

This calculation is useful for procurement, transportation, storage, and project estimation.

Class A, Class B and Class C GI Pipes

Class A GI pipes are generally associated with lighter-duty applications and lower weight compared with heavier classes. Selection should consider the application and required specification.

Class B GI pipes are commonly used for general plumbing, water supply, construction, and engineering applications. They provide a practical balance between weight, strength, durability, and cost when correctly specified.

Class C GI pipes are generally associated with heavier-duty requirements where greater wall thickness and higher weight are required. Their additional weight should be considered during transportation, lifting, storage, and structural planning.

The appropriate class should always be selected according to the application and applicable specification rather than weight alone.

Indian Standards for GI Pipes

IS 1239 Part 1 is commonly referenced for steel tubes and includes Light, Medium, and Heavy classes along with requirements for dimensions, mass, and galvanized or black surface conditions.

IS 4736 is associated with zinc coating requirements for galvanised steel products and is referenced in testing related to zinc coating uniformity.

IS 3589 covers steel pipes for water and sewage applications and may be applicable depending on pipe type, dimensions, and intended service.

The exact applicable standard and edition should always be confirmed before procurement, especially for critical engineering, infrastructure, water, and industrial projects.

Factors Affecting GI Pipe Weight

Several factors influence the final weight of GI pipes:

Nominal pipe diameter

Outside diameter

Wall thickness

Pipe class

Zinc coating

Manufacturing tolerances

Steel specification

Manufacturer and manufacturing process

A larger diameter or thicker wall generally increases the weight per metre. Zinc coating also contributes to the finished weight.

GI Pipe Applications

GI pipe weight charts are useful for material estimation, transportation planning, structural calculations, procurement, warehouse management, lifting operations, and project budgeting.

Knowing the approximate weight per metre helps contractors estimate total material requirements and allows procurement teams to compare supplier quotations more effectively. Weight information is also useful for determining vehicle capacity, storage requirements, pipe supports, racks, hangers, and lifting arrangements.

How to Choose the Right GI Pipe

GI pipe selection should be based on the application and required specification rather than weight alone. Buyers should consider:

Nominal size

Outside diameter

Wall thickness

Pipe class

Operating or pressure requirements

Galvanizing specification

Applicable Indian Standard

Required quantity

Manufacturer

Delivery location

For critical projects, the manufacturer's technical documentation should be reviewed before final procurement.

2. What is the weight of a 2-inch GI pipe?

According to the reference chart, a 2-inch pipe weighs 3.68 kg/m for Class A, 4.63 kg/m for Class B, and 5.56 kg/m for Class C.

3. How do I calculate GI pipe weight?

Use Weight = 0.02466 × WT × (OD − WT), where OD and WT are in millimetres.

4. What is the GI pipe price per kg in 2026?

There is no fixed price. The indicative reference range used here is ₹65–₹82/kg, subject to market conditions and commercial factors.

5. How is GI pipe price per metre calculated?

Price per metre = Weight per metre × Price per kg.

6. Does galvanizing increase pipe weight?

Yes. Zinc coating contributes to the finished weight of a galvanised pipe.

7. What is the difference between Class A, B and C?

They represent different weight and wall-thickness categories. Generally, heavier classes have greater wall thickness and higher kg/m.

8. How do I calculate the weight of a 6-metre pipe?

Multiply the kg/m value by six. For example, 5 kg/m × 6 m = 30 kg.

9. Which Indian standard is commonly used for GI pipes?

IS 1239 Part 1 is commonly referenced for steel tubes, including Light, Medium, and Heavy classes and galvanized surface conditions.

10. Why is GI pipe weight important?

It helps with material estimation, transportation, structural calculations, procurement, inventory, lifting, and project cost estimation.
