Q&A on Expanded Metal
1. What does #9 mean in expanded metal?2. How is expanded metal made?1. #9 in expanded metal refers to the gauge of the metal sheet used in the manufacturing process. The gauge number represents the thickness of the metal sheet, with lower numbers indicating thicker sheets and higher numbers indicating thinner sheets. For example, a #9 expanded metal sheet is thicker than a #14 expanded metal sheet.2. Expanded metal is made by cutting and stretching a metal sheet to create diamond-shaped openings. The process involves slitting and stretching the metal sheet with a machine called an 'expander.' The metal sheet is first slit in a regular pattern, and then the individual slits are stretched to form the diamond-shaped openings. This results in a strong and lightweight mesh-like material that is commonly used in construction, industrial, and decorative applications. Expanded metal can be made from various materials, including stainless steel, aluminum, and carbon steel, providing different levels of strength, durability, and corrosion resistance.
