DESCRIPTION
A rigid steel scale is a precision measuring tool crafted from high-quality stainless steel or hardened spring steel, designed for accurately measuring and marking linear distances. Renowned for its durability, the rigid steel scale is resistant to wear, corrosion, and physical damage, making it an ideal choice for professional and educational environments such as engineering, architecture, woodworking, and metalworking. The scale features finely etched, easy-to-read markings in both metric and imperial units—commonly millimeters, centimeters, and inches. Its rigid, straight construction ensures precise measurements and also allows the scale to serve as a reliable straightedge for drawing or scribing lines. Most rigid steel scales are finished with a satin or non-glare chrome coating to minimize reflections and facilitate clear visibility under various lighting conditions. The ends are usually ground square for accuracy, and the entire scale is designed to maintain its shape even with prolonged and repeated use.
