The complete guide to flat steel products — coil types, coatings and finishes, and how to source them export-direct for roofing, appliances and fabrication.
Home › Guides › Steel Coil & Flat Products Guide
Key takeaways
- HRC is thicker/economical; CRC is thin, smooth and precise.
- GI = galvanized; PPGI = prepainted (colour-coated) for roofing.
- Z-coating class (Z80–Z275) sets galvanized durability.
- PVDF paint lasts far longer than polyester on PPGI.
Hot rolled vs cold rolled coil
HRC (1.5–16 mm, economical) vs CRC (0.3–3 mm, smooth, precise). Detail: HRC vs CRC.
Galvanized coil (GI)
GI coil in Z80–Z275 zinc. Coating guide: Z275 explained.
Prepainted coil (PPGI)
PPGI — colour-coated in polyester or PVDF, full RAL range. See GI vs PPGI, paint systems and what is Galvalume.
Roofing & cladding
Corrugated roofing sheet and purlins complete the roofing package.
Stainless flat products
Stainless sheet & coil in 304/316 for architecture, food and chemical use.
Sourcing coil in bulk
Specify thickness, width, grade and coating, request a 3.1 MTC, and agree Incoterms. We export coil to markets worldwide.
Frequently asked questions
What is the difference between GI and PPGI?
GI is galvanized (zinc-coated) steel; PPGI is GI with a factory paint finish (colour + extra durability) for roofing and cladding.
Which paint lasts longer on PPGI?
PVDF holds colour far longer than polyester (15–20+ years) but costs more.
Do you supply cut-to-length sheet?
Yes — coil, sheet and roll-formed roofing cut to your lengths.
