FAQs

• Q: Can you provide custom dimensions or coatings?

  Absolutely. We offer Deep Customization Services: 
  - Dimensions: Width 200–2,000 mm, Thickness 0.3–25 mm  
  - Coatings: Precision-controlled zinc (20–275 g/m²) or tin (1.1–11.2 g/m²) layers  
  - Surface finishes: 10+ options (matt, mirror, embossed, etc.)  
  - Feasibility report delivered within 48 hours for custom requests 
  

• Q: What are the tensile/yield strength or hardness values of the products?

  A: Properties vary by process (e.g., cold-hardened coils: 1,200 MPa tensile strength;  Zn-Fe alloy coatings: 150–220 HV hardness).  Detailed data are available in technical specifications or upon request.

• Q: How is corrosion/wear resistance ensured?

  A: Corrosion resistance is enhanced through alloy design (e.g., Zn-Ni, Fe-Zn layers), porosity control (<8 pores/cm²), and post-treatment (e.g., hydrogen baking, passivation), with salt spray performance 3–4x better than standard coatings.

• Q: What is the minimum order quantity (MOQ)?

  Standard MOQ starts at just 5 tons with flexible trial orders: 
  - Hot-rolled/cold-rolled coils: 1 coil (~3 tons)  
  - Galvanized/tinplate coils: 2 coils  
  - Custom specifications: 15 tons (3 mixed specs allowed) 
  

• Q: How do you ensure product defect detection and consistency?

  A: Full-process quality control includes eddy-current testing (>0.1 mm crack detection), thickness gauging, and salt spray testing.  Each coil is supplied with a Material Test Certificate (MTC) and inspection report.

• Q: Conventional specification range?

  A: Thickness: 1.5mm to 20mm (adjustable according to the production line)
  Width: 600mm - 2200mm (minimum/maximum dimensions must be marked)
  Inner diameter: Φ610mm (common) or Φ508mm (please confirm the company's production line)
  Outer diameter: Determined by the roll weight, usually ≤2500mm

• Q: How to package and transport?

  A: Conventional packaging: Moisture-proof paper + steel band binding, or customized packaging as per customer requirements (such as wooden cases, waterproof film);
  Transportation methods: road transportation, railway transportation, sea transportation. We can assist in contacting logistics or deliver goods according to the logistics specified by the customer.

• Q: How long is the shelf life of the product?

  A: Under normal storage conditions (dry, well-ventilated and non-corrosive environment), the shelf life is 12 months (from the date of manufacture).

• Q: How to obtain the sample?

  A: Small-sized samples can be provided free of charge (freight collect). Please fill out the "Sample Application Form" and indicate the purpose.
