Structural & Alloy Steel — Engineering Reference

Structural steels are the backbone of construction and heavy industry. Grades in this category are specified primarily by their yield strength, tensile strength, and weldability — the three properties that determine whether a building stands or a bridge holds.

Key Standards

ASTM A36/A572/A516, EN 10025, JIS G3101/G3106, GB/T 700/1591

Common Uses

Building frames, bridges, pressure vessels, shipbuilding, offshore platforms, pipelines

Engineer's Note

When selecting a structural grade, match the required yield strength to the design load, but also verify Charpy impact values if the structure will operate below freezing — many structural steels undergo a ductile-to-brittle transition at low temperatures.
