Mild Steel (MS) H Beams are one of the most commonly used structural steel components in construction, industrial projects, and infrastructure. Known for their excellent strength-to-weight ratio and versatility, MS H Beams are widely applied in building frameworks, bridges, warehouses, and heavy machinery support structures. Understanding their specifications is crucial for engineers, architects, and procurement professionals to select the right product for their projects.
Weight (kg) = Length (m) * Cross-sectional area (m²) * Density (kg/m³)
where:-
Length of the Beam in Meters.
Cross-sectional area of the Beam in Square Meter.
Density of Mild Steel in Kilograms per Cubic Meter.
Density of Mild Steel is 7.85 kg/m³
ASTM (USA): A36, A572 — common structural steel grades.
EN (Europe): S235, S275 — widely specified in civil and industrial construction.
JIS (Japan): SS400, SM490 — general structure and semi‑high strength grades.
GB (China): Q235B, Q345B — standard grades for structural applications.
Matching the steel grade with the project’s load, environmental, and fabrication requirements is essential for structural safety and longevity.
To ensure optimal performance, always check mill test certificates, material grades, and fabrication standards provided by suppliers. A well‑specified MS H Beam can significantly enhance structural safety and efficiency in your next project.
What is MS H Beam?
MS H Beam, or Mild Steel H Beam, is a structural steel beam with an “H” shaped cross-section. Unlike I-beams, H beams have wider flanges, providing better load distribution and stability, making them ideal for heavy load-bearing applications.Specifications of Prime Hot Rolled Mild Steel H Beam
