Double-Sided PE Color Coated Aluminum Coil

1. Core Advantages

1060 & 3003 soft aluminum substrate: O temper ductile aluminum alloy with uniform internal texture, perfect for complex deep drawing to produce seamless aluminum circles without cracking, stable forming performance for cookware blanks.

Synchronous double-sided uniform PE coating: Automatic two-side primer and top coat roller coating, equal 23-30μm paint thickness on front and back, consistent gloss and color without unilateral shade deviation.

Balanced stress anti-warp design: Double-face coating offsets single-side coating internal stress, effectively prevent coil warping after slitting, guarantee flat finished aluminum panels and circular cookware blanks.

Dual high coating adhesion: Complete double-sided degreasing, circulating water washing and non-chromium passivation treatment, paint tightly bonded with aluminum base, no peeling during flanging, punching and deep drawing.

Double-sided anti-scratch protective film: Both coated surfaces laminated transparent PE film, isolate friction and fingerprint during transportation, cutting and bending, keep coating intact.

Eco-friendly indoor grade polyester paint: Low odor, zero harmful volatile organics, fully comply with RoHS environmental standard, safe for kitchen food contact and indoor living decoration.

Custom dual-color matching service: Support same color on two sides or different front/back colors as project design, full RAL color system and custom color matching available.

Multi-scene double-sided decorative raw material: Meet all products requiring visible coating on both sides, widely used for kitchen cookware, household appliances, indoor wall panels and ACP decorative core sheets.

2. Production Process

Aluminum base coil uncoiling → Double-sided full degreasing & circulating water washing → Two-side non-chromium chemical passivation → Hot air drying → Synchronous double-side primer roller coating & high temperature curing → Double-face PE top coat roller coating & secondary baking → Cooling → Double-sided protective film laminating → Finished coil rewinding → Full surface & thickness inspection → Moisture-proof export packaging

Online dual coating thickness detector and surface defect camera monitor front and back coating synchronously to ensure consistent coating quality of every jumbo coil.

5. Export Packaging Standard

Double-sided coated aluminum coil wrapped with multi-layer waterproof PE film and thick kraft paper, two coated surfaces separated by protective film to avoid friction scratch. Coil fixed on fumigated wooden pallet with steel strapping to prevent deformation during ocean transportation. Clear shipping label marked alloy grade, thickness, width, front & back color code, net weight and batch number. Fumigation certificate can be supplied for all overseas customs clearance. Narrow slit small coils packed into independent corrugated cartons and stacked on pallets as complete shipment sets.

6. Inspection & After-sales Service

Four strict pre-shipment inspections: Double-side coating thickness test, cross-cut adhesion test, front-back color difference comparison, surface scratch & flaw full inspection, dimension & weight verification. Complete supporting documents provided: MTC material test certificate, coating performance inspection report, RoHS certificate, MSDS safety data sheet, commercial invoice and packing list. Professional technical team provides deep drawing and bending processing guidance at any time. If any coating or surface quality defects are found within 7 working days after goods receipt, please provide clear photos and video evidence; our team will reply within 24 hours and offer solutions including re-production, supplementary shipment or reasonable compensation.

FAQ

Q1: Can this double-sided coated coil make deep drawing aluminum circles without paint falling off?

A: Yes, synchronous double passivation and double-layer coating structure ensure excellent adhesion, conventional deep drawing and flanging will not cause coating cracking or peeling.

Q2: Can I choose different colors for front and back sides?

A: Absolutely, we support custom different front and back color according to your decoration and product design requirements.

Q3: Is double-sided coating more expensive than single-sided coil?

A: The cost is slightly higher, but it eliminates secondary painting process for double-sided visible products, overall comprehensive processing cost is lower for mass production.

Q4: Do you have stock of same-color double-sided white/grey coils?

A: Mainstream single-color double-sided coils are in warehouse stock, delivery within 3 working days; custom different front-back colors require 7 working days production lead time.

Q5: Will two coated sides rub and scratch during transportation?

A: We attach independent protective film on both sides, and separate each coil with kraft paper during packaging to avoid surface friction damage.
