5. Angle bar (L-bar)

An angle bar, also known as an L-bar or angle iron, is a commonly used structural steel component in the construction of transmission towers and marine shipbuilding.
In the construction of transmission towers, angle bars are used as important structural members to provide stability and support. They are often used as braces, cross arms, and diagonal members to withstand the various loads and forces that the tower may experience, such as wind, ice, and the weight of transmission lines. Angle bars are chosen for their strength, versatility, and cost-effectiveness in these applications.
In marine shipbuilding, angle bars are also widely utilized. They are used for various applications such as framing, stiffening, and supporting structures. Angle bars provide structural integrity and stability to the ship’s hull and superstructure. They are used in the construction of bulkheads, frames, decks, and other critical components. Angle bars are preferred in shipbuilding due to their high strength-to-weight ratio, ease of fabrication, and cost-effectiveness.
