Indian Structural Angles

Indian Structural Angles are L-shaped structural steel sections designed for use in a wide range of construction, fabrication and engineering applications. Their simple and versatile profile makes them suitable for structural frames, bracing systems, trusses, supports, towers, platforms, brackets and fabricated assemblies.

Structural angles are primarily available in two configurations: Equal Structural Angles, where both legs have the same width, and Unequal Structural Angles, where the two legs have different widths. The selection of the appropriate profile depends on the structural design, required dimensions, loading conditions and connection requirements.

At Moksh Tubes & Fittings LLP, we cater to requirements for Indian Structural Angles based on specified size, thickness, grade, length, quantity and applicable standards. These profiles can be considered for both standard procurement and project-based structural steel requirements.

Indian Structural Angles are valued for their practical fabrication characteristics and suitability for applications requiring structural support, reinforcement, framing and connections. They can be used in combination with other structural steel sections to create reliable and efficient fabricated structures.

For specific projects, customers can provide their required angle dimensions, material grade, length, quantity and technical specifications so that the appropriate product requirement can be evaluated.

Mechanical Properties – Indian Structural Angles

(Typical minimum values as per IS 2062; actual values vary with grade, quality/sub-grade and material thickness.)

Standard / Grade	IS 2062 E250	IS 2062 E275	IS 2062 E350	IS 2062 E410
Tensile Strength (MPa), Min.	410	430	490	540
Yield Strength (MPa), ≤20 mm	250	275	350	410
Elongation (%), Min.	23	22	22	20

The underlying IS 2062 values show that yield strength is thickness-dependent—for example, E250 is 250 MPa up to 20 mm, 240 MPa for 20–40 mm and 230 MPa above 40 mm
