Steel rulers are primarily used for measuring and making lines, although they can be used for a variety of other tasks, depending on their size and shape. Steel rulers are manufactured in a variety of sizes and shapes, ranging from 6 inches in length to 10 feet in length. Common features of steel rulers include a solid base to provide stability, a sharp edge for accurate measurements and clear, easy to read numerals.
Steel rulers are typically made of steel which has been highly polished for a smooth surface to prevent scratches, dents and other damage. Steel has excellent wear-resistance and strength as metals go, making it ideal for fabrication use such as measuring and marking. The raw material may range from cold drawn steel or hot rolled steel to tool grade steel or stainless steel. Different grades of steel have different properties and different levels of tolerance, allowing for more or less flexibility in terms of applications.
Most steel rulers come with a variety of markings for a variety of measuring purposes. For example, one side of a steel ruler may have imperial measurements in inches, while the other side may feature metric measurements in millimeters. Additionally, steel rulers may feature numbers or lines indicating fractional measurements, such as half- and quarter-inch marks. Steel rulers also come with a variety of special features such as built-in protractors and painted measurements.
When it comes to purchasing a steel ruler, users should consider their specific needs, such as the type of measurements they will be making and the environment in which the tool will be used. Steel rulers are available in a variety of sizes, although most are available in the traditional 18-inch and 24-inch lengths. Users should also consider features such as widths, thicknesses, and steel grades and have a good understanding of the desired applications in order to choose the best steel ruler for their needs.
Steel rulers are one of the most widely used tools for measuring, marking and drawing lines. Steel rulers provide users with an extremely accurate and long lasting measuring tool, designed for use in a variety of measuring applications and environments. Knowing the desired specifications and level of accuracy required for an application can help users make the best choice when purchasing their steel ruler.
