Which materials can be used to construct wireways?

The use of aluminum, steel, and non-metallic materials for constructing wireways is standard in the industry due to their durability, strength, and resistance to various environmental factors. Aluminum is lightweight yet strong, offering good corrosion resistance, which is beneficial for outdoor or humid environments. Steel, on the other hand, provides excellent structural integrity and can carry heavier loads, making it ideal for more robust applications. Non-metallic materials can include options like PVC or other plastics, which are typically used in less demanding environments where ease of installation and resistance to corrosion are more vital than strength.

Other materials listed, such as wood, concrete, and glass, while they may have specific applications, are not commonly used to construct wireways because they do not offer the necessary balance of electrical safety, strength, and adaptability found in the metallic and non-metallic options. Fiberglass and ceramic, while useful in some contexts, do not meet the broader range of typical requirements needed for wireways compared to the combinations mentioned in the correct answer.
