In the use of standard steel tape, the main reasons for the error are the following: 1. Error of temperature change Generally, the thermal expansion coefficient of steel tape measure is α = 1.25x 10-5, and the temperature difference per meter per degree changes only by one eighty thousand. However, the same steel tape measure will still produce large length changes in an environment with large temperature difference, affecting the measurement results. The error of temperature change is taken into account in the ruler formula.

Steel tape is also called box ruler. It is an ordinary measuring tool for measuring length. According to the different structure of the tape tape, the tape is divided into four types: self-tape, brake tape, roll cassette tape and roll rack tape. The self-roll tape and brake tape are mostly tape measures below 5m. The nominal length of the rolling cassette tape and the rolling rack tape is more than 5m. Category of steel tape The nominal length of steel tape: take an integer multiple of o.5 for steel tape below 10rn; For steel tape above 10m, take an integer multiple of 5. Tape measure specifications are Im, 2m, 3m, 3.5m, 5m, 10rn, 15m, 20m, 30m, 50m, 60m, 70m, 80m, 100m, etc. Steel tape can be used to roughly measure the length, width, height, thickness and other dimensions of large workpiece, and can also be used in geodetic survey.

Steel tape is also known as tape measure, box ruler, it is a line of the scale, by comparing with the measured size, and by the ruler direct reading of the universal length measuring tool. According to the different structure, the tape measure is divided into rolling cassette tape, automatic tape, brake tape and sounding steel tape.
