Steel Grades for Solar & Structural Steelwork
ENSOL Engineering TeamPublished 2026-02-011 min read
The steel grade sets the yield strength, which in turn decides how much section is needed to carry the loads. In India, structural steel is commonly specified to IS 2062.
Common grades
IS 2062 covers grades such as E250 (formerly Fe410) and higher-strength E350 (Fe490). Higher grades allow lighter sections for the same load, saving weight and, sometimes, cost.
Sections and forming
Solar structures use hot-rolled and cold-formed sections. Cold-formed profiles are efficient for lightweight framing; hot-rolled sections carry heavier loads. Grade and section are chosen together with the coating.
