Engineered for lifecycle value: a zinc-protected substrate with color topcoat that resists fading, chalking, and corrosion in real-world environments.
Built for manufacturing: stable formability through roll forming, press braking, and corrugation with minimal paint micro-cracking.
Aesthetic control at scale: matte, embossed, and wood-grain effects with consistent RAL tone across batches for façade-grade uniformity.
Right coating for the job: PE / SMP / HDP / PVDF systems to balance capex with service-life economics.
Low friction logistics: standard coil IDs, export-grade packing, and services (slitting, decoiling, cutting) for ready-to-run supply.

PRODUCT DESCRIPTION
Coated Color Painted Steel & PPGI Coils deliver the clean, uniform look architects want and the predictable forming behavior fabricators require. A zinc layer shields the base steel from red rust; the color topcoat then adds a smooth, tactile surface that resists fingerprints and weathering while projecting crisp RAL tones. On the line, coils feed quietly, paint stays intact around bends, and off-press parts stack without scuffing—meaning fewer rejects and steadier takt time on roofing, cladding, doors, and appliance panels.
Behind the aesthetic, each coil is built for fit-for-purpose performance: choose PE for cost-effective interiors, SMP/HDP for durable exteriors, or PVDF when UV stability is paramount in sun-drenched climates. With thicknesses from 0.12–1.5 mm and widths up to 1500 mm, you can optimize profile weight without compromising stiffness, then specify surface effects—matte, embossed, or wood grain—to align with your customer’s brand language. The result is a coil that looks premium, forms cleanly, and lasts longer in service.

Layered protection (zinc + organic coating) helps block moisture and airborne contaminants.
Colors stay closer to spec; façades age uniformly, reducing patchwork repairs and disputes.
Fewer repaints mean steadier OPEX and cleaner warranty math.
Controlled bake and top-/back-film thickness help coatings flex through tight radii.
Roll forming, press braking, and punch operations see fewer edge cracks and chips.
Less rework, fewer cosmetic rejects, and calmer production meetings.
Matte finishes read calm and premium; embossed textures diffuse glare on sun-facing cladding.
Wood-grain prints offer warmth without the upkeep of porous materials.
Smooth, “quiet” feed on decoilers adds to perceived quality on the shop floor.
From DX51D to G550 strength levels to match stiffness or deep-draw needs.
Coating families (PE/SMP/HDP/PVDF) let you tailor UV/chemical resistance to site conditions.
Wide size envelope reduces secondary processing and non-standard SKUs.
Standard coil IDs and export packaging play nicely with existing handling gear.
Processing services (slit, cut-to-length, protective film) shorten your time-to-fab.
Stable lead windows and MOQ help project managers keep Gantt charts honest.
| Topcoat | UV/Color Retention | Typical Applications | Risk Mitigation Notes |
|---|---|---|---|
| PE | Good | Interiors, soffits, light-duty exterior panels | Budget-fit; confirm color/shine targets and expected repaint cycles |
| SMP | Better | General roofing & walling | Improved chalk/fade; attractive TCO for inland climates |
| HDP | Better+ | Industrial/coastal, high sun | Strong UV & chemical resistance; expands warranty headroom |
| PVDF | Best | Premium façades, signage, OEM appliances | Top-tier fade resistance; ideal where brand color fidelity is non-negotiable |
DX51D–DX54D, SGCC/CGCC, S280/350/550GD to balance formability vs. rigidity.
Recognized standards: AISI / ASTM / BS / DIN / GB / JIS for cross-market compliance.
Typical category ranges: thickness 0.10/0.12–1.50 mm; width 600–1250 mm.
Coil IDs commonly 508/610 mm; typical coil weights 3–8 MT for decoiler compatibility.
Zinc coating classes widely available across the market: Z40–Z275 (≈30–275 g/m²).
Organic coating reference bands: top 10–40 μm / back 3–14 μm; systems 2/1, 2/1M, 2/2.
Matte, embossed/flower-grained, printed (wood/brick/pattern), zero/small spangle options.
Protective PVC film for scuff control during profiling and installation.
Roofing, wall cladding, doors/windows, façades, appliance skins, furniture, signage, electrical enclosures.
Slitting, decoiling, cut-to-length, bending, punching, profiling; OEM-ready panelization on request.
Seaworthy export packing; FCL/LCL; multi-modal routing (sea/rail/road/air) per schedule risk.
Moisture-control layers and edge protection to reduce transit blemishes.
MOQs typically 5–10 tons; lead times 7–30 days depending on spec and load plan.
Payment terms often include T/T and L/C, with major electronic options supported.
T-bend, pencil hardness, salt-spray, and UV exposure protocols are common validation methods.
Third-party inspection (e.g., ISO/SGS), mill test certificates, and batch color charts available.
Include this full module in future product pages as a standardized “spec dimensions” block for fast cross-product comparison.
Building envelopes: long runs of roofing and cladding where gloss and color uniformity matter across elevations and over time.
Appliances & OEM panels: door skins, side panels, and backs with smooth feed and reduced scuff risk in assembly.
Signage & branding: high-visibility surfaces that need tight RAL matching and fade resistance.
Industrial & coastal projects: chemical plants, logistics parks, and waterfront construction where HDP/PVDF protect the investment.
Interior architecture: partitions and ceilings with matte, low-glare finishes for a composed visual field.
Sensory note: matte finishes feel quieter to the eye and fingers—no harsh glare, no gritty texture—so spaces read calmer and more premium.
Coating integrity checks: routine T-bend and cupping tests to confirm film flexibility during forming.
Surface durability: pencil hardness and cross-hatch adhesion to benchmark scratch and chip resistance.
Corrosion resistance: neutral salt spray and humidity cycling to project performance in aggressive atmospheres.
Color control: spectrophotometer checks against master RAL; batch-to-batch delta-E tracking for visual continuity.
Traceability & documentation: MTCs, coating logs, and inspection reports mapped to coil IDs to support audits and warranty conversations.

Use table as directional guidance in spec reviews; confirm project-specific exposure, warranty targets, and local standards.
Spec discipline you can audit: we publish the critical parameters (film builds, zinc class, grade/hardness) and keep batch-level coating logs. Auditable documentation de-risks after-sales negotiations.
Configured to your line: width up to 1500 mm and multiple hardness bands reduce secondary processing and SKU proliferation.
Shorter time-to-fab: in-house slitting, decoiling, cutting, and protective film application ship material that is truly ready-to-run.
Steady delivery windows: MOQ from 5 tons and standard lead-time brackets align with project milestones, minimizing schedule whiplash.
Service culture built on testing: we lean on T-bend, adhesion, and salt-spray/UV data—because numbers make production meetings shorter and calmer.
Yes. Solid RALs and custom prints are available with batch color tracking. We can supply small panels for approval before mass production. Protective PVC film is available for delicate textures.
HDP or PVDF typically offers the best lifecycle value in high-UV, salt-laden environments. We’ll size film builds to your warranty goals and installation method to reduce edge-cut exposure.
508 mm and 610 mm are the common IDs; 3–8 MT is typical for smooth handling. If you need heavier or lighter coils for crane or mandrel limits, we can plan the load accordingly.
G30–G90 is supported (with Z-class equivalents commonly available). Higher zinc mass improves sacrificial protection—particularly at cut edges and scratches—subject to forming needs.
Slitting, cut-to-length, decoiling, bending, punching, and profile rolling are available. We can ship ready-to-form blanks/panels to reduce queue time and scrap.
We lock a master color standard, measure delta-E on each batch, and recommend single-lot procurement for contiguous elevations. Where multiple lots are unavoidable, we sequence panels to minimize perceptible variation.
MOQs start from 5 tons. Standard windows are 7–30 days depending on spec, coating schedule, and vessel space. Shared forecasts help us reserve capacity and reduce variance.
Yes. Mill Test Certificates, coating records, and third-party inspections can be arranged. We also support on-site witness during key tests on request.
