Comprehensive Engineering Guide to Mild Steel Beams
Mild Steel Beams (MS Beams), commonly referred to as Structural I-Beams, Joists, and H-Beams, are prime structural steel profiles engineered with an optimized cross-section consisting of two parallel horizontal flanges connected by a central vertical web. This structural geometry delivers an exceptional moment of inertia (second moment of area) along the major axis, enabling high load-carrying capacity while minimizing dead weight in civil and structural engineering projects.
At Mildsteelbeam.com, we are premier stockists, suppliers, and distributors of prime IS 2062 Grade E250 (Quality A/BR/BO) and Grade E350 (High Tensile) Mild Steel Beams manufactured under strict adherence to IS 808:1989 dimensions and IS 1852 rolling tolerances. Available from ISMB 100 up to heavy structural ISMB 600 and Wide Flange (ISWB/NPB) sections, every consignment is accompanied by 100% verified Mill Test Certificates (EN 10204 Type 3.1).

Multi-Storey Commercial & Industrial Towers
Axial load-bearing Wide Flange (ISWB) and Universal Beams for power plants, petrochemical refineries, and cement silos.
Mild Steel Beam Theoretical Weight Calculation Formula
The theoretical weight of Mild Steel Beams is standardized by the Bureau of Indian Standards under IS 808:1989 based on sectional dimensions and the standard density of structural mild steel (7,850 kg/m³).
Practical Example: To calculate the consignment weight of 20 pieces of standard 12-meter long ISMB 250 beams (rated at 37.30 kg/m):
Single Beam Weight = 37.30 kg/m × 12 m = 447.60 kg
Total Consignment Weight = 447.60 kg × 20 Pcs = 8,952.00 kg (8.95 Metric Tons)
For commercial billing and dispatch, all consignments leaving our Raipur central stockyard are weighed on computerized electronic weighbridges to ensure 100% transparent and certified invoicing.
Frequently Asked Questions
Key technical, design, and commercial answers regarding Mild Steel Beams, ISMB specifications & order logistics.
ISMB (Indian Standard Medium Weight Beam) has tapered inner flange surfaces and narrower flange widths, making it highly effective for bending loads such as roof rafters and floor beams. ISWB (Indian Standard Wide Flange Beam) features broader, flatter flanges with higher lateral stiffness, making it the preferred choice for heavy vertical columns, axial load-bearing structures, and high-capacity gantry foundations.
We supply MS Beams conforming to IS 2062 Grade E250 (Quality A, BR, BO) with minimum yield strength of 250 MPa, IS 2062 Grade E350 (High Tensile) with minimum yield strength of 350 MPa, ASTM A36, and ASTM A992 standards.
Our standard ready stock lengths are 6.0 Meters, 9.0 Meters, 10.0 Meters, and 12.0 Meters. We also provide custom precision band-saw cutting to supply exact required lengths directly to your fabrication drawing specifications, minimizing site scrap.
Yes, all prime structural shipments are accompanied by genuine EN 10204 Type 3.1 Mill Test Certificates (MTC) verifying cast heat numbers, chemical composition (C, Mn, Si, S, P), and mechanical properties (Yield Strength, Tensile Strength, Elongation, and Charpy Impact values where applicable).
Yes, for critical highway bridge girders, high-load crane gantries, and power plant infrastructure, we supply 100% Ultrasonically Tested (UT) beams in compliance with IS 4225 and ASTM specifications.
