2. Manufacturing Processes The method of production plays a critical role in pricing. Factory-produced metal sheets often benefit from economies of scale, reducing the cost per unit. However, advanced manufacturing techniques, such as precision cutting and surface treatments, can add to the production costs. The level of automation and technology used in factories also impacts pricing, as more advanced production lines may require higher initial investments.

Leading manufacturers typically offer a range of galvanizing processes, such as hot-dip galvanizing or electro-galvanizing. Hot-dip galvanizing involves immersing the metal in molten zinc, resulting in a thicker coating that provides superior corrosion resistance. On the other hand, electro-galvanizing applies a thin layer of zinc through an electrochemical process, often resulting in a more polished finish, but may not offer the same level of protection as hot-dip galvanization.

2. Features and Functionality Overlock machines come with varying features, such as multiple thread options, differential feed, and built-in stitches. Machines that offer a wider array of functionalities typically come with a higher price tag. For instance, a 4-thread overlock machine can create more complex seams than a basic 3-thread model, making it worth the extra investment for advanced users.

3. Efficiency With faster stitch speeds and a series of automated features, heavy-duty machines can significantly reduce the time spent on projects. Features such as automatic needle threaders and adjustable stitching allow users to focus on creativity rather than mechanical adjustments.
