First, steels length size energy and environmental protection

Steels length size is the most basic size of all kinds of steels, it is to point to the length of steels, width, height, diameter, radius, inner diameter, outer diameter and wall thickness. The legal units of measurement for length of steels are meters (m), centimeters (cm) and millimeters (mm). In current usage, the inch is also used, but it is not a legal unit of measurement.

Sizing the scope of steels is an effective measure to save materials

. Range measurement is the length or length by width is not less than a certain size, or length, length by width from how much to how many size range delivery. The production unit can produce and supply according to the size requirements.
Irregular ruler (usually length) where the product size (length or width), within the scope of the standard, and do not require a fixed size is called irregular ruler. Indefinite length is also called general length (ruler). Metal materials delivered by irregular gauge can be delivered within the specified length range. For example, ordinary round steels no larger than 25mm, whose usual length is defined as 4-10m, then the length of the round steels within this range can be

Fixed size according to the order requirements cut into a fixed size called fixed size. The metal material to be delivered must be of the length specified by the buyer in the order contract. For example, if the contract states that the goods are delivered at a fixed length of 5m, the materials delivered must all be 5m long. Any material shorter than 5m or longer than 5m is disqualified. But in fact, the delivery can not be 5m long, so it is allowed to have positive deviation, but not negative deviation.
Multiple ruler According to the order requirements of the fixed size cut into integer multiple called multiple ruler. The length of metal material to be delivered shall be an integer multiple (plus saws) of the length specified by the buyer in the order contract (called a single length). For example, the buyer requires the length of single ruler to be 2m in the order contract, so the length is 4m when cut into double feet, and 6m when cut into three feet, and one or two saws are added respectively. The amount of saw is specified in the standard. Only positive deviation is allowed, negative deviation is not allowed

If the length of a short ruler is less than the lower limit of indefinite length specified in the standard, but not less than the allowable shortest length, it is called short ruler. For example, it is stipulated in the water and gas transmission steel pipe standard that 10% (calculated by the number of pipes) 2-4m long short steel pipe is allowed in each batch. 4M is the lower limit of indefinite length, and the shortest allowable length is 2m.
A narrow ruler whose width is less than the lower limit of variable ruler width specified in the standard, but not less than the allowable narrowest width is called a narrow ruler. Share information, improve technical level, and pay attention to the proportion and the narrowest scale specified in the relevant standards when delivering goods according to the narrowest scale.
