Frequently Asked Questions
What standard governs GI structural fabrication in India?+
IS 2062 covers structural steel grades; IS 800 governs steel design. Fabricated GI structures are hot-dip galvanized per IS 2629, typically 65–85+ µm for outdoor environments.
What zinc coating thickness is specified for outdoor GI structures?+
IS 2629 specifies a minimum average zinc coating of 610 g/m² (~85 µm) for most outdoor applications. IES applies 65–100 µm depending on section thickness and end-use environment.
