Angle bars, also known as angle irons or L-shaped bars, are commonly used structural elements in construction and various industrial applications. They are typically made of steel and have a 90-degree angle shape. In Ghana, as in many other countries, angle bars are widely used in construction projects, fabrication, and general structural support. The availability of angle bars in Ghana would likely depend on the local steel and construction material market. They can be purchased from steel suppliers, hardware stores, and construction material dealers. The sizes, lengths, and specifications of angle bars can vary, so it's important to choose the appropriate size and grade based on the specific requirements of your project.
