HR sheet & corrugated roofing: thickness and length in practice
Hot-rolled plate for platforms and tanks; corrugated and GP lines for envelopes—how thickness bands line up with real builds.
HR sheet runs from lighter gauges through heavy plate—pick thickness for deflection and load, not habit. Ultra and heavy options are worth a call when your drawing steps outside standard stock; we keep strategic sizes across godowns but not every thickness on every day.
Corrugated profiles are about pitch, overlap, and wind: sheet thickness and length bands in the catalogue match typical purlin spacing. GP and zinc-coated sheets add corrosion resistance for ducts and cladding—state finish and colour expectations when you enquire.
FRP panels are a different trade—day-lighting and diffusion—pair them with the metal system so flashings and fixings don’t fight each other at the ridge.
