Hatch covers, containers, and equipment accessories are indispensable in industries such as dairy, chemicals, and brewing, where they serve as essential components. The surface treatment of the hatch not only affects its appearance but also, especially in dairy equipment, can impact its usability. Therefore, its surface treatment is a crucial step in the production process. Today, Bent Hatch introduces several commonly used surface treatments:

1. Internal and External Mirrored Surface: This type of manhole is commonly used in high-demand equipment such as food and dairy machinery, featuring a bright and shiny surface that is as smooth as a mirror, with an attractive and glossy appearance.

2. Internal and External Matte: These manholes have relatively lower requirements; they don't need to achieve a mirror-like finish. A slight coarse polishing is sufficient. The specifics depend on the customer's requirements and desired outcome.

3. Pickling Treatment: This type of manhole is commonly used in industrial applications, where a direct acid wash of the surface is sufficient and no further treatment is required. Many construction sites frequently use this type, which can help reduce costs.
