Buy Imperial Steel with No Minimum Order Value or Quantity
Imperial Steel is one of the most important materials in the construction and manufacturing industry, thanks to its versatility, strength and durability. Exceeding or falling short of the required dimension can result in unnecessary costs, wasted material or, in the worst case, failure of a structure.
When purchasing steel products, it is important to select the correct dimension based on the intended use and required mechanical properties. They are critical to various industrial applications and determine both the mechanical properties and cost of a project.
Imperial Steel dimensions refer to the different sizes and shapes in which steel products are manufactured and used. Interestingly, US customary units are now defined in terms of the metric system:
