The two main types of metallic conduit and raceway are rigid and flexible. Rigid conduit offers solid protection. Flexible metal conduit allows for bends and twists without using extra hardware. Prewired conduit, or armored cable, offers an all-in-one solution with the wires already running through it.

Flexible Conduit Systems are typically used in installations where flexibility is required to make connections, and where the installation may be subjected to shock and vibration. Product selection should take into consideration: 

• The specific application and industry requirements 
• System temperature ratings 
• System ingress ratings Indoor or outdoor installations
•  Approvals/certifications 
• Reliability of performance over time.   

When electrical wires and circuitry need mechanical protection and support in an industrial electrical installation between two points, one of the common methods used is rigid Conduit Systems. Typically, rigid metal conduit is heavy-duty galvanized steel tubing installed with threaded fittings. They can also provide structural support for electrical cables, panels, and other equipment. An added feature of a rigid metal conduit system is that it can be direct buried and encased in concrete. In addition to use in ordinary environments, the rigid system solution is well suited for harsh environments.
