advantages and disadvantages of metal
Answers
Explanation:
Metals generally provide the following advantages over plastic fabrication: Heat resistance: Metals typically have a higher melting-point and are less likely to degrade under elevated temperatures. Improved strength: Metal grades tend to be stronger, harder, and more durale than their plastic counterparts.
Metal may rust, especially if the structure is located outside and at the mercy of the rain. This not only affects the outside of a structure but also the inside of it. Metal buildings are known for being difficult to seal completely from water penetration. Other disadvantages include the difficulty in attaching hooks and shelves to metal, which requires professional tools, and metal's less attractive appearance compared to wooden structures.
