Hemaokang Steel (Shandong) Co., Ltd. proudly presents our ASTM Standard Pre-coated Corrugated Board – a premium building cladding solution designed for durability, aesthetics, and long-term performance. With a width of 1000mm and a thickness of 0.5mm, this galvanized steel sheet is pre-coated for superior corrosion resistance and a sleek finish. As a trusted supplier in the global market (annual export value US$50M–US$100M), we ensure every roll meets the highest quality standards, backed by our ISO9001 certified production process.
Our product is engineered for building cladding applications where strength, weather resistance, and visual appeal are critical. The corrugated profile provides excellent structural rigidity, while the pre-coating adds an extra layer of protection against UV rays, moisture, and pollutants. Whether used for industrial warehouses, commercial facades, or residential roofing, this material delivers consistent performance and easy installation.
Key Features & Benefits

Frequently Asked Questions
Q1: What is the minimum order quantity (MOQ) for this product?
A: The MOQ for standard colors is 1 ton (approx. 200–300 square meters depending on thickness). For custom colors, the MOQ is 3 tons. We can also accommodate smaller trial orders upon request.
Q2: Can you provide samples before bulk order?
A: Yes, we offer free samples (A4 size) with the customer paying shipping costs. For larger samples, we can arrange a small paid sample order. Please contact our sales team.
Q3: Is this product suitable for both roofing and wall cladding?
A: Absolutely. The 0.5mm thickness provides sufficient strength for both vertical wall cladding and sloped roofing. However, for flat roofs or high snow load areas, we recommend consulting our engineers for possible reinforcement.
Q4: How do you ensure the coating does not peel or fade over time?
A: Our pre-coating process uses high-quality polyester or PVDF paints (optional) with a primer layer. The paint is applied before corrugation, allowing uniform coverage and adhesion. We also perform UV resistance and cross-cut tests to guarantee durability.
Q5: What is the typical lead time for this product?
A: For standard colors and sizes, lead time is 15–20 working days after receiving deposit. For custom colors or special dimensions, allow 25–30 working days. Urgent orders can be expedited with prior arrangement.
Q6: Do you offer installation guidance or technical drawings?
A: Yes, we provide installation manuals and standard lap details. If you need customized cut-to-length or specific corrugation profiles, we can adjust the production accordingly. Our technical team is available for online support.
Q7: Is the product available in different zinc coating weights?
A: Yes. The standard zinc coating is Z275 (275 g/m²). We can also supply Z180, Z350, or others based on your corrosion resistance requirements.
Q8: How do you package the sheets to prevent damage during transport?
A: Sheets are packed in bundles with steel strapping, placed on wooden pallets, and covered with waterproof paper and plastic film. For long-distance sea freight, we add extra edge protectors and corner boards. Each bundle is labeled with specifications for easy identification.
