Colour-coated steel / PPGI (pre-painted galvanised iron)
What it is
Pre-painted galvanised iron - coated steel coil painted on a continuous line before fabrication, rather than after. It is used for roofing, cladding, appliances and pre-engineered buildings
It is the furthest downstream step available to a flat steel processor and carries the widest spread over the underlying coil
Impact on industries
- The main margin escape from commodity cold rolling - paint systems, colour and warranty create a branded, specification-led product
- Demand is pulled by PEB, warehousing and appliance growth, and by roofing replacement in rural and semi-urban markets
- Brand and channel matter here in a way they never do in plain coil, so distribution investment earns a durable return
- Requires continuous coating lines and paint chemistry capability, so entry is capital-intensive and quality failures are visible for years
