Open Architecture
Open architecture design avoids problems of bacteria growth inside enclosed structures like tubular steel frames that become breached.

The concern nowadays about using tubular frame members in machine construction is that over time someone or something will end up making a perforation in the tubular component allowing bacteria and/or water to enter. Once inside the bacteria is free to propagate in a protected area, away from wash-down sprays and cleaning disinfectants. Commercial Manufacturing is well capable of producing tubular frame members that have no open holes. However, a growing number of customers are opting for open frame architecture where only sheet steel is used for structural members. When we build open architecture frames we make sure that water is able to drain away from every surface. These designs are potentially more costly to build, and may take a bit longer to clean; however, they successfully avoid the problem of creating potential havens for bacteria growth.
