Steel rules, also called rulers, are essential in any shop when accuracy matters. Steel rules are inherently more accurate than folding rules because they are made in one piece and so avoid the inaccuracies, however small, which are inherent in folding rules because of the to play in their hinges. The requirements for accuracy in steel rules vary greatly, however, and the range of products varies likewise.
Steel rules come in rigid and flexible versions. While their primary purpose is accurate measurement, they can also be used as guides for laying out lines, and if rigid enough, for cutting. The thinner, more flexible rules can also be used to measure rounded or cambered work.
The differences in the prices of rules result from the various production methods, which also determine accuracy and legibility. Most rules are made by cutting the required length from a roll of band spring steel, with etched graduations. Rules made by this method are adequate for most applications and reasonably priced.
Higher-priced rules are cut, not stamped, from plate steel (stamping would cause the material to warp), and the edges are ground. Graduations are machined, much deeper than etched graduations, longer-lasting, and easier to read in poor light.
1. Steel rules made by STARRETT in the USA are made from high-quality steel to the highest standards of precision. STARRETT machine-divided rules provide uniformity of line width and depth. Graduations are generally deeper than in cheaper, photo-engraved rules and will last longer. The numbering size is distinctive and more readable than in ordinary rules. The rules are satin-chrome finished for easier reading and rust resistance.
2. Our steel rules made in Germany are made of stainless spring steel, accuracy +-0.5 mm per 1m; +-0.7 mm per 2m; +-0.9 mm per 3m; +-1.3 mm per 5m. Photo-engraved (etched) markings on a satin surface provide glare-free reading.
You need only determine which rule from those shown below is most suitable for your purposes.
