Common Applications of RAL 9002 Color Coated Steel Coil
The prepainted galvanized steel coil we supply is widely used in:
- Roofing and wall cladding – industrial buildings, warehouses, agricultural sheds.
- Roll-formed profiles – roof sheets, sandwich panel skins, decking.
- Home appliances – back panels, casings, and liners.
- Automotive parts – interior trim and structural components.
- Furniture – shelving, lockers, and office partitions.
Because RAL 9002 is a neutral cream white, it is a preferred color for modern architectural designs and industrial equipment where a clean, bright appearance is required. Our galvanized steel coil substrate ensures excellent corrosion resistance in moderate to high humidity environments.
Quality Control and Certifications
As a trusted PPGI supplier China, we implement rigorous quality checks at every stage:
- Incoming raw material inspection – HDGI coils from Baosteel, Shougang, and other top mills.
- In-line paint thickness monitoring using X-ray gauges.
- Off-line tests: salt spray (ASTM B117), MEK rub (≥100 times), T-bend (0T–3T), impact (9J).
- Color measurement with spectrophotometer – ΔE ≤ 1.0 compared to RAL standard.
- Third-party inspection (SGS, BV) available at buyer’s cost.
Our ISO certification and 15+ years of export experience guarantee that every coil meets international standards (JIS G3312, EN 10169, ASTM A755).
FOB Pricing and Logistics from Qingdao
We offer transparent FOB Tianjin pricing for all RAL 9002 PPGI coils. Price depends on base metal grade, zinc coating weight, paint type, thickness, and order quantity. Typical lead time is 15–25 working days after deposit. Our Qingdao factory is located near major ports (Tianjin Xingang Port, Rizhao Port), ensuring fast and cost-effective container loading. We can arrange 20GP, 40GP, or 40HQ containers with a maximum coil weight of 5 tons per piece for safe handling.
Frequently Asked Questions about RAL 9002 PPGI Coil
1. What is the difference between PPGI and PPGL?
PPGI uses a hot dip galvanized steel substrate (zinc coating), while PPGL uses a Galvalume (aluminum-zinc alloy) substrate. For most roofing and wall applications, prepainted galvanized steel coil offers excellent corrosion resistance at a lower cost. If higher heat reflection or salt-spray resistance is required, we recommend PPGL.
2. Can you produce RAL 9002 with a glossy or matte finish?
Yes. Our standard gloss level is 30–40% (semi-gloss). We can adjust gloss from 20% (matte) to 80% (high gloss) for the same RAL color PPGI. Please specify your requirement when ordering.
3. What is the minimum order quantity for RAL 9002 PPGI coil?
Our MOQ 25 tons per size and color. For mixed colors in one container, the MOQ is 5 tons per color. We accept trial orders of 25 tons for new customers to evaluate our quality and service.
4. How do you ensure color consistency between batches?
We use a spectrophotometer to measure L*a*b* values against the RAL 9002 standard. Each batch is retained as a reference sample. For large projects, we can produce the entire quantity in one continuous production run to guarantee color uniformity.
5. What is the typical delivery time to Europe or the Middle East?
Related Products from ChinaCNU Steel
Sea freight from Qingdao to major European ports (Rotterdam, Hamburg) takes approximately 30–35 days. To Middle East ports (Jebel Ali, Dammam), 20–25 days. Production time is 15–25 days, so total lead time is 5–8 weeks depending on destination.
