ISMB & ISMC Weight Chart 2026 – Kg/m as per IS 808

Last Updated: September 29, 2026

The ISMB & ISMC Weight Chart 2026 provides useful reference data for engineers, contractors, fabricators, architects, steel buyers, procurement teams, and construction professionals. ISMB beams and ISMC channels are widely used in industrial buildings, warehouses, structural frames, platforms, machinery supports, infrastructure, and fabrication projects.

This guide covers commonly used ISMB and ISMC sizes, weight in kg/m, approximate 6-metre weight, calculation formulas, applications, price references, and purchasing considerations. For final procurement and structural design, the exact section designation, dimensions, unit mass, steel grade, and applicable standard should always be verified.

What Is ISMB?

ISMB stands for Indian Standard Medium Beam. It is a hot-rolled structural steel section with an I-shaped profile consisting of a web and two flanges. ISMB beams are commonly used where structural members are required to resist bending, shear, compression, and other design loads.

Common applications ...
... include:

Industrial buildings

Warehouses

Factory structures

Steel frames

Platforms

Bridges

Machinery supports

Roof structures

Infrastructure projects

For example, ISMB 200 represents a beam with a nominal depth of approximately 200 mm. The exact dimensions and sectional properties should be checked against the applicable section table.

What Is ISMC?

ISMC stands for Indian Standard Medium Weight Channel. It is a hot-rolled steel channel with a C-shaped profile.

ISMC channels are commonly used for structural supports, purlins, bracing, equipment bases, platforms, machinery supports, trailer frames, walkways, and general fabrication.

Common applications include:

Industrial sheds

Warehouse structures

Structural supports

Purlins

Bracing

Platforms

Equipment supports

Trailer frames

Gantries

General engineering

IS 808:2021 for ISMB and ISMC

IS 808:2021 – Hot Rolled Steel Beam, Column, Channel and Angle Sections – Dimensions and Properties is the relevant Indian Standard for dimensional and sectional-property information for these hot-rolled structural sections.

For a 2026 reference article, buyers should verify the exact section against the applicable standard and project specification. Online charts can differ because of section series, dimensional references, or source data.

The kg/m value represents the reference unit weight of the section and is useful for calculating total steel tonnage.

ISMB & ISMC Weight Calculation

The basic formula is:

Total Weight = Weight per Meter × Length × Quantity

For example, if you require 20 pieces of ISMC 150, each 6 metres long:

16.4 × 6 × 20 = 1,968 kg

Therefore, the approximate requirement is 1.968 MT.

For an ISMB example, 10 pieces of ISMB 250, each 12 metres long:

31.5 × 12 × 10 = 3,780 kg

Therefore, the approximate total weight is 3.78 MT.

For a 6-metre section, simply multiply the kg/m value by 6. For example:

ISMC 200 = 22.1 × 6 = 132.6 kg

ISMB 300 = 42.1 × 6 = 252.6 kg

Actual supplied weight may vary according to the applicable manufacturing tolerance and section specification.

The two sections should not be substituted simply because their unit weights are similar. Selection depends on span, loading, support conditions, section properties, connections, buckling, and deflection requirements.

ISMB & ISMC Price Per Kg in India 2026

ISMB and ISMC prices vary according to size, steel grade, manufacturer, quantity, location, freight, taxes, market conditions, and material availability.

For preliminary September 2026 budgeting, a general MS channel reference may be around ₹55–₹80/kg, but this is not a fixed market price.

For example, if 1,640 kg of ISMC material is quoted at ₹59/kg:

1,640 × ₹59 = ₹96,760

The final invoice may additionally include GST, freight, loading, unloading, cutting, testing, and certification charges.

Always request a current quotation for the exact section, grade, quantity, and delivery location.

Applications of ISMB and ISMC

ISMB beams are commonly used in industrial buildings, warehouses, structural frames, platforms, bridges, machinery supports, commercial buildings, and infrastructure projects.

ISMC channels are frequently used for structural supports, purlins, bracing, platforms, equipment bases, machinery supports, industrial sheds, trailer frames, walkways, gantries, and fabrication.

The correct section should be selected according to engineering requirements rather than weight alone.

Buying Checklist

Before purchasing ISMB or ISMC sections, verify:

Section designation

Dimensions

Unit weight

Steel grade

Length

Manufacturer

Heat number

Material Test Certificate

Chemical composition

Mechanical properties

Surface condition

Applicable standard

Quantity and delivery requirements

For structural projects, final section selection and design should be confirmed by a qualified structural engineer.
