Problem Breakdown

To determine how metal studs are formed, we need to analyze the given options and identify the correct method used in the metalworking industry.

Relevant Concepts

1. Cold forming: A process where metal is shaped at room temperature without the need for heating.
2. Extruding molten steel: A method of shaping material by forcing it through a die while in a molten state.
3. Forging: Involves shaping metal using localized compressive forces, typically at high temperatures.
4. Hot rolling: The process of rolling metal at a temperature above its recrystallization temperature.

Analysis and Detail

• Cold forming: Suitable for many types of metal shapes but does not usually apply to heavy-duty constructions such as metal studs.
• Extruding molten steel: Primarily used for creating long shapes but not typically used for metal studs.
• Forging: Generally results in stronger materials but is not commonly associated with the production of metal studs.
• Hot rolling: Commonly used in construction-related applications, including metal studs, as the hot rolling process allows for better shaping and forming of materials.

Verify and Summarize

After analyzing the methods, hot rolling stands out as the most applicable method for forming metal studs used in construction due to its efficiency and the resulting material properties.

Final Answer

Metal studs are formed by hot rolling.
