PPGI Coil Price Guide: Cost Factors, Quotes & Wholesale Tips
Thickness & zinc coating are the biggest cost drivers.
PE/SMP/HDP/PVDF changes durability and total lifecycle cost.
Use the RFQ template below to request a comparable quote.
8 Cost Factors That Change PPGI Coil Price
Below is the fastest way to understand why supplier quotes differ. If you want a reliable PPGI coil quote, you must specify the parameters in the third column.
Factor How it impacts price What buyers should specify
Base metal (GI / GL) Different substrate cost and corrosion baseline. GI or GL; steel grade if required.
Thickness More steel per meter → higher cost. Thickness (mm) and tolerance if critical.
Width & tolerance Width affects yield, trimming, and processing. Width (mm) + tolerance needs.
Zinc coating (Z60–Z275) Higher zinc coating generally costs more and improves corrosion resistance. Z level (g/m²) matched to environment.
Paint system (PE/SMP/HDP/PVDF) Higher durability systems typically cost more. Paint system + target application (roofing/panels/cladding).
Paint thickness (Top/Back, μm) Thicker coating improves durability but increases cost. Top μm / Back μm (don’t leave this blank).
Color & finish (RAL, matte, wrinkle, wood grain) Special finishes and strict color matching can add cost. RAL code + gloss/finish requirements.
MOQ / quantity Small lots have higher unit cost due to setup and waste. Total MT + delivery schedule.
Export packing & tests Stronger packing and extra tests can increase cost. Packing standard + required tests (if any).
Good practice
If a quote doesn’t state zinc coating and top/back paint thickness, treat it as incomplete. For available specs and options, check the PPGI coil product page .Coating weight/mass designation (GalvInfoNote)
Typical Buyer Scenarios & What Drives Cost
PPGI coil for roofing, panels, and cladding prioritize different specs. Matching specs to use-case prevents “cheap” failures.
Scenario 1
PPGI Coil for Roofing
Key drivers: zinc (Z) level, paint system, top paint thickness.
Hot sun / coastal → prioritize durability over “lowest quote”.
If you’re unsure, start from stable roofing specs, then optimize cost.
Scenario 2
PPGI Coil for Sandwich Panels
Key drivers: thickness tolerance, coating adhesion, forming performance.
Cheap coating often shows issues after profiling/lamination.
Panel lines care about consistency more than “one-time cheap”.
Scenario 3
PPGI Coil for Cladding
Key drivers: color matching, batch control, weather resistance.
Finish (matte/wrinkle) can change cost and lead time.
If you need stable color across projects, specify batch rules.
See available specs and options on our PPGI coil product page before requesting quotes.
PPGI Quote Checklist (Send these first)
Want a clean quote with less back-and-forth? Send the 6 must-have specs first. They decide whether quotes are comparable.
6 must-have specs
Thickness (mm)
Width (mm)
Zinc coating: Z__ g/m²
Paint system: PE / SMP / HDP / PVDF
Paint thickness: Top __ μm / Back __ μm
Color: RAL + finish (gloss / matte / wrinkle)
Optional (improves accuracy)
Base metal: GI / GL
Coil ID & coil weight
Quantity (MT) + delivery schedule
Incoterms + destination port
Standard / tests (ASTM / EN / JIS; T-bend, impact, etc.)
Export packing requirement (if route is humid/long)
Wholesale or “Cheap” PPGI Coil: Where Buyers Get Burned
“Cheap” usually means something is cut: zinc, paint thickness, batch control, or export packing. The table below shows what to watch.
What gets cut What happens How to avoid it
Low zinc coating Higher corrosion risk, shorter service life. Specify Z level (e.g., Z120 / Z180 / Z275) based on environment.
Thin paint thickness Faster fading/chalking, lower durability. Specify top/back paint thickness (μm) in every quote request.
Weak batch control Color difference between batches. Confirm color sample approval + batch rules for projects.
Simplified export packing Transit damage, white rust risk. Require standard export packing (anti-moisture + protection).
Unclear standard Delivery disputes and inconsistent performance. Specify ASTM/EN/JIS (or your agreed QC standard) in RFQ.
Buying for projects? Start from stable specs on the PPGI coil product page, then optimize cost.
FAQ: PPGI Coil Price, MOQ, and Quotation
These are the questions we see most often when buyers compare PPGI coil price and quotes.
What affects PPGI coil price the most?
Thickness, zinc coating (Z level), and paint system are the biggest drivers. Paint thickness (top/back μm) is the most commonly “missing” parameter in incomplete quotes.
How do I request a comparable PPGI coil quote?
Use the RFQ template above. If you omit zinc coating and top/back paint thickness, you will receive quotes that can’t be compared fairly.
What is MOQ for wholesale PPGI coil orders?
MOQ varies by thickness, color, and paint system. If you need small lots, be prepared for higher unit cost due to setup and production waste.
Does higher zinc coating always mean better?
Higher zinc generally improves corrosion resistance, but the “right” Z level depends on environment (coastal/industrial) and the paint system used.
PE vs PVDF: when is PVDF worth it?
PVDF is often chosen for stronger weather resistance in harsh UV/coastal conditions. If the project requires longer appearance retention, PVDF may be worth the higher cost.
Why do quotes vary so much between suppliers?
Most variation comes from missing or different specs: zinc coating, paint thickness, paint system, tolerances, packing, and testing requirements.
What export packing is standard?
Export packing commonly includes moisture protection, edge protection, and secure strapping. If your route is humid or long, packing requirements should be stated in the RFQ.
How to control color difference between batches?
Confirm RAL code, finish/gloss targets, sample approval, and batch management rules before mass production—especially for cladding projects.
