Structural steel and stainless steel angles, channels, beams and tees — with the grades, section
dimensions, weights and tolerances you need to specify them.
Product Overview
The Sections That Carry the Structure
We supply equal and unequal angles, channels, I beams, H beams and tees in structural
carbon steel and high-strength steel, in stainless steel and duplex for corrosive and hygienic
environments, and in aluminium where weight matters.
Sections are supplied to Indian, European and American standards, in standard lengths or cut to
length, black, primed or galvanised. Every lot is traceable to its heat number and supplied with a
mill test certificate to EN 10204 Type 3.1 or 3.2. When your project needs independent verification,
inspection by your nominated agency is carried out before dispatch.
Each section is drawn as a cross-section, with the dimensions used to order it. The same letters are used in the section tables further down the page.
Equal Angle
a × a × t · IS 808 (ISA) · EN 10056
Two legs of the same length at 90°. For frames, bracing, trusses, supports and edge protection.
Unequal Angle
a × b × t · IS 808 · EN 10056
One leg longer than the other, to suit the load or the connection. For lintels, purlins and framing.
Channel
ISMC · UPN · UPE · PFC · C
A web with two flanges on one side. For purlins, frames, stair stringers, trailer chassis and bracing.
I Beam
ISMB · IPE · UB · S shapes
Narrow flanges and a deep web, efficient in bending. For floor and roof beams, and crane girders.
H Beam & Wide Flange
HEA · HEB · HEM · ISHB · UC · W
Flanges about as wide as the section is deep, strong about both axes. For columns and heavy beams.
Tee
b × h × t · EN 10055 · cut from I & H
A flange with a single stem, rolled or cut from I and H beams. For truss chords, stiffeners and brackets.
Materials & Grades
Structural Grades, Indian, European and American
Structural steel is graded by its minimum yield strength and, for some grades, its toughness at low temperature. Choose a family to see the grades we supply.
Structural Carbon Steel
The everyday grades for buildings, sheds, platforms, pipe racks and equipment structures. The yield strength shown is for the thinnest sections; it falls a little as thickness increases.

Strength & Weight
Stronger Steel, Lighter Sections
A higher-yield grade lets a lighter section carry the same load. The first chart compares grades; the second shows how the weight of an IPE beam grows with its depth.

Equal angle weights are calculated as t × (2a − t) × density, without the root and toe radii; published tables are about 1 to 2 % higher.
Weights are for carbon steel at 7.85 g/cm³; stainless steel sections of the same size weigh about 1 % more. Indian Standard ISA angles, ISMC channels and ISMB, ISWB and ISHB beams to IS 808, and American W shapes, are also supplied; send the designation and we will confirm dimensions and weight.

What is the difference between IPE, HEA and HEB beams?
IPE beams have narrow flanges and a deep web, so they are efficient in bending and used mainly as floor and roof beams. HEA and HEB are wide-flange H sections, with flanges about as wide as the section is deep, used for columns and heavily loaded beams. HEB has thicker flanges and web than HEA of the same size, so it is heavier and stronger. See the section tables.
What is the difference between ISMB and IPE beams?
ISMB is the Indian Standard medium-weight beam to IS 808, and IPE is the European parallel-flange I beam to EN 10365. They are similar in use but differ in dimensions and weight: ISMB flanges are tapered, while IPE flanges have parallel faces. Designs should use the section tables of the standard the drawing calls for.
What does S355J2 mean?
It is a structural steel grade to EN 10025. S stands for structural steel, 355 is the minimum yield strength in MPa for thin sections, and J2 means the steel is impact tested to give at least 27 joules at −20 °C. JR is tested at 20 °C and J0 at 0 °C.
How is an angle specified?
An angle is specified by its leg lengths and thickness in millimetres. An equal angle such as 50 × 50 × 6 has two legs of 50 mm and a thickness of 6 mm. An unequal angle such as 100 × 65 × 8 has one leg of 100 mm and one of 65 mm. See the drawings.
Are stainless steel angles, channels and beams available?
Yes. Stainless steel angles and channels are hot rolled or cold formed, and larger beams and channels are also made by laser fusion welding of plates, in grades such as 304, 316L and duplex 2205. They are used in food, pharmaceutical, chemical, water and marine structures.
What documents are supplied with structural sections?
Every lot is supplied with a mill test certificate to EN 10204 Type 3.1 or 3.2, traceable to the heat number, with chemical composition, tensile and, where the grade requires it, impact test results. When third-party inspection is called for, the agency's inspection release note is included. More on our quality & inspection page.
