• Handle Attachment: Wire bails or plastic handles are securely attached to the pail body using specialized equipment.

5. Surface Treatment and Finishing:

• Cleaning and Pre-treatment: Pails undergo thorough cleaning to remove oils and contaminants, followed by surface pre-treatment (e.g., phosphating) to enhance adhesion for subsequent coatings.
• Internal Lining: For corrosive or sensitive contents, an internal epoxy-phenolic, vinyl, or food-grade lining is applied via spray or roller coating and then cured. This protects the product from the steel and the steel from the product.
• External Coating/Painting: The exterior receives a protective and decorative coating, often a baked enamel or custom color, applied via spray or roller. This enhances corrosion resistance and allows for branding.
• Curing: All applied coatings are thermally cured in high-temperature ovens to ensure optimal adhesion, hardness, and chemical resistance.

6. Quality Control and Testing:

Throughout the process, stringent quality control measures are implemented. Finished pails undergo a series of tests:

• Leak Testing: Pails are typically air-pressure tested (e.g., at 0.1-0.2 bar for several seconds) to detect any leaks.
• Drop Tests: For UN-rated pails, drop tests from specified heights with specific contents are performed to meet ISO 16104, ANSI MH14.1, and UN performance standards.
