What material are machine guards typically made of?

Machine guards are typically made of metal or plastic because these materials provide the necessary strength and durability required to protect users from moving parts and hazardous situations in machinery. Metal, such as steel or aluminum, is often used due to its robustness and ability to withstand impacts and wear. Plastic is favored in some applications for its lightweight properties and corrosion resistance while still offering adequate protection. The combination of these materials allows for effective safeguarding of machinery, ensuring safety without compromising functionality or ease of operation.

Other materials, such as wood or cardboard, do not provide the necessary strength or durability needed for protective guarding, while glass or fabric are generally too fragile or flexible to serve as appropriate protection in an industrial environment. Rubber or silicone, though useful in certain applications, lack the structural integrity needed for permanent guards on machines.
