👉 Dunnages are a type of steel that is commonly used in construction and engineering for its strength, durability, and ability to withstand various loads. They are typically made from high-quality carbon steel with a low-carbon content, which makes them more resistant to corrosion and wear than other types of steel. Dunnages are often used in structures such as bridges, buildings, and infrastructure projects to ensure their longevity and safety during construction or operation.
