GI Pipe Price Disclaimer
GI pipe prices are subject to market fluctuations and may vary depending on steel prices, manufacturer, pipe class, wall thickness, zinc coating, order quantity, GST, freight charges, and delivery location.
The prices shown on this page should be treated as reference information and not as a fixed quotation. For the latest GI pipe price, buyers should request a current quotation based on the required size, specification, quantity, and delivery location.
GI Pipe Weight and Price: Why Both Matter
GI pipe weight and price are closely connected when planning construction, plumbing, industrial, agricultural, and infrastructure projects. While pipe dimensions determine the physical characteristics of a pipe, weight per meter helps buyers estimate total material requirements, transportation loads, handling requirements, and project costs.
A GI pipe weight chart provides the approximate weight of different pipe sizes according to their diameter, wall thickness, and applicable class. By using this information, contractors can estimate the total weight required for a project before purchasing the material.
For example, if a project requires 500 meters of GI pipe and the selected pipe weighs 10 kg per meter, the estimated material weight is:
500 × 10 = 5,000 kg
Therefore, the project would require approximately 5 metric tonnes of pipe, excluding packaging and other materials.
Weight information is also useful when comparing supplier quotations. Two pipes may have the same nominal size but different wall thicknesses. The heavier pipe contains more steel and may have a different price. Therefore, buyers should compare size, wall thickness, class, weight, manufacturer, and specification rather than comparing only the price per meter.
How to Calculate GI Pipe Price
GI pipe price can be estimated using the pipe weight and applicable price per kilogram.
Formula
GI Pipe Price Per Meter = GI Pipe Weight Per Meter × Price Per Kg
Example
Suppose
- GI Pipe Weight = 5 kg/m
- Applicable Price = ₹80/kg
Then:
5 × ₹80 = ₹400 per meter
For a 6-meter pipe:
₹400 × 6 = ₹2,400 per pipe
This is an example calculation only. Actual GI pipe prices may include GST, freight, loading, unloading, cutting, packaging, and other commercial charges.
What Is a GI Pipe Weight Chart?
A GI Pipe Weight Chart is a reference table that provides the approximate weight of galvanized iron pipes according to their nominal size, outside diameter, wall thickness, class, and weight per meter.
These charts are widely used by engineers, contractors, fabricators, suppliers, architects, and procurement teams for material estimation and project planning.
The weight is commonly expressed in kilograms per meter (kg/m). Once the weight per meter is known, the total weight of a required pipe length can easily be calculated.
Total Pipe Weight Formula
Total Pipe Weight = Weight Per Meter × Total Pipe Length
For example, if a GI pipe weighs 7.35 kg/m and the required length is 100 meters:
7.35 × 100 = 735 kg
The estimated total pipe weight is therefore 735 kg.
How to Read a GI Pipe Weight Chart
Reading a GI pipe weight chart becomes easier once you understand the main specifications.
Nominal Pipe Size
Nominal size is generally expressed in inches, such as:
- 1/2 inch
- 3/4 inch
- 1 inch
- 1 1/4 inch
- 1 1/2 inch
- 2 inch
- 2 1/2 inch
- 3 inch
- 4 inch
- 6 inch
Outside Diameter
Outside diameter, or OD, represents the external diameter of the pipe and is generally specified in millimetres.
Wall Thickness
Wall thickness indicates the thickness of the steel wall. A thicker wall generally results in a heavier pipe.
Weight Per Meter
Weight per meter is generally expressed in kg/m. It tells you approximately how much one meter of pipe weighs.
Pipe Class
GI pipes can be supplied in different classes or specifications. Generally, lighter classes have lower weight while heavier classes have greater wall thickness and higher weight.
GI Pipe Weight Calculation Formula
The theoretical weight of a steel pipe can be estimated using its outside diameter and wall thickness.
Formula
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 is useful for theoretical weight calculations. However, the actual weight of a finished GI pipe may differ slightly because of manufacturing tolerances and the zinc coating applied during galvanizing.
For critical applications, always verify the actual dimensions and manufacturer-certified weight.
GI Pipe Classes and Weight Variations
Class A GI Pipes
Class A GI pipes are generally associated with lighter-duty applications and lower weight compared with heavier pipe classes.
Their relatively lighter construction can make them suitable for applications where lower material weight is required and the operating conditions do not demand heavier wall thickness.
Before selecting Class A pipes, users should verify the required pressure, application, dimensions, and applicable standard.
Class B GI Pipes
Class B GI pipes are commonly used for general plumbing, water supply, construction, and engineering applications.
They provide a balance between weight, strength, durability, and cost. Because of their versatility, medium-duty GI pipes are frequently considered for residential, commercial, and industrial requirements.
Class C GI Pipes
Class C GI pipes are generally associated with heavier-duty applications where greater wall thickness and higher pipe weight are required.
They may be considered for demanding installations, subject to the application requirements and relevant specifications.
When using heavier GI pipes, project planners should account for the additional weight during transportation, lifting, storage, and structural support calculations.

GI Pipe vs MS Pipe Weight
GI pipes and MS pipes are both steel-based products, but GI pipes receive a zinc coating through the galvanizing process.
The zinc coating provides additional corrosion protection and can slightly increase the finished weight compared with an uncoated steel pipe.
For accurate calculations, buyers should use the manufacturer’s GI pipe weight rather than assuming that the weight of a galvanized pipe will be exactly the same as an equivalent uncoated MS pipe.
The final weight may depend on:
- Pipe dimensions
- Wall thickness
- Steel specification
- Zinc coating
- Manufacturing tolerance
- Manufacturer
For large projects, even small differences in weight can affect transportation costs and material calculations.
Indian Standards for GI Pipes
Indian standards are important when selecting GI pipes because they provide requirements relating to dimensions, manufacturing, testing, and product quality.
IS 1239 Part 1
IS 1239 Part 1 is commonly referenced for steel tubes used for general engineering purposes. Buyers should confirm the current applicable edition and requirements for their specific application.
IS 4736
IS 4736 relates to hot-dip zinc coatings on iron and steel articles and is relevant to galvanizing requirements.
IS 3589
IS 3589 covers steel pipes for water and sewage applications and may be relevant depending on the type and intended application of the pipe.
Always confirm the applicable standard and product specification before procurement, especially for critical engineering projects.
Factors Affecting GI Pipe Weight
Several factors can influence the final weight of a GI pipe.
Pipe Diameter
Larger diameter pipes generally require more steel material and therefore have higher weight.
Wall Thickness
Wall thickness is one of the most important factors affecting pipe weight. A thicker pipe wall generally means greater weight per meter.
Zinc Coating
The galvanizing process adds a zinc coating to the steel surface. The coating contributes to the final product weight.
Manufacturing Tolerances
Actual dimensions can vary within permitted manufacturing tolerances, resulting in small differences between theoretical and actual weight.
Steel Specification
The steel used for manufacturing can influence the final product characteristics and applicable weight requirements.
Manufacturer
Different manufacturers may have slightly different production and coating practices. For critical applications, manufacturer-specific technical data should be checked.
Practical Applications of GI Pipe Weight Charts
GI pipe weight charts are useful in many industries and applications.
Material Estimation
Contractors can calculate the approximate total material weight required for a project.
Transportation Planning
Total pipe weight helps determine suitable vehicle capacity and transportation requirements.
Structural Load Calculations
Engineers can use pipe weight when calculating loads on pipe supports, racks, hangers, and structures.
Procurement Planning
Procurement teams can compare quantities and supplier quotations more effectively when they know the expected pipe weight.
Warehouse Management
Pipe weight information helps warehouse managers plan storage areas, racks, handling equipment, and floor-loading requirements.
Crane and Lifting Planning
For large or heavy pipes, weight information helps determine suitable lifting equipment and safe handling arrangements.
GI Pipe Weight for Transportation Planning
Transportation is one of the most practical uses of a GI pipe weight chart.
Before dispatching a large quantity of GI pipes, the total material weight should be estimated.
Formula
Total Weight = Weight Per Meter × Total Length
For example:
- Pipe weight = 8 kg/m
- Required quantity = 1,000 meters
8 × 1,000 = 8,000 kg
The estimated pipe weight is therefore 8,000 kg or 8 tonnes.
The actual transport planning should also consider bundles, packaging, loading equipment, vehicle capacity, and applicable road regulations.
GI Pipe Weight for Project Cost Estimation
GI pipe weight can also be used to estimate material cost when suppliers quote prices on a weight basis.
Example
Required pipe weight:
5,000 kg
Applicable rate:
₹80/kg
Estimated material cost:
5,000 × ₹80 = ₹4,00,000
This is an example calculation only. The final project cost may vary after adding GST, transportation, loading, unloading, fabrication, and other applicable charges.

Frequently Asked Questions About GI Pipe Weight and Price
A GI Pipe Weight Chart is a reference table showing the approximate weight of GI pipes according to size, outside diameter, wall thickness, class, and weight per meter.
The weight of a 2-inch GI pipe depends on its class and wall thickness. The reference table above provides different weight values for Class A, Class B, and Class C pipes.
The theoretical weight can be estimated using:
Weight (kg/m) = 0.02466 × WT × (OD − WT)
where OD is the outside diameter in millimetres and WT is wall thickness in millimetres.
There is no single fixed GI pipe price per kg because prices depend on size, class, manufacturer, zinc coating, quantity, steel market conditions, GST, freight, and delivery location. Contact the supplier for the latest quotation.
GI pipe price per meter depends on pipe size, wall thickness, class, manufacturer, quantity, and current market conditions. A supplier should provide the final price based on the required specification.
Yes. Galvanizing adds a zinc coating to the steel surface, so the finished GI pipe can weigh slightly more than an equivalent uncoated steel pipe.
Class A, Class B, and Class C represent different pipe specifications and weight/wall-thickness categories. Generally, lighter classes have lower weight, while heavier classes have greater wall thickness and higher weight.
Multiply the weight per meter by six.
For example, if the pipe weighs 5 kg/m:
5 × 6 = 30 kg
Therefore, the approximate weight of a 6-meter pipe is 30 kg.
IS 1239 Part 1 is commonly referenced for steel tubes used for general engineering purposes. The applicable standard should always be confirmed based on the pipe type and application.
