The factory process behind metal lunch boxes often involved a series of intricate steps. First, the raw materials were sourced and cut into the appropriate sizes. Next, the metal sheets underwent printing, where vibrant colors were applied to create eye-catching designs. The pieces were then shaped, bent, and fused together, creating a sturdy construction that could withstand the rigors of daily use. Finally, a protective coating was applied to guard against rust, ensuring these lunch boxes would endure for years.

2. Manufacturing Processes The production of corrugated stainless steel sheets involves precise manufacturing techniques. Factors like the complexity of the corrugation, thickness of the steel, and customization options (such as coatings and finishes) can significantly impact the final price. Advanced manufacturing methods that ensure higher quality and durability often demand greater investment, which can elevate costs.
2. Corrosion Resistance Many metal flashing products are treated with protective coatings or are made from materials like aluminum or stainless steel, which are naturally resistant to rust and corrosion. This property ensures that the flashing maintains its performance and appearance over time, which is crucial for maintaining roof integrity.
