关于烟台彩钢卷长度尺寸，你知道多少？
1烟台彩钢卷钢材范围尺寸
规定钢材的规格范围是节约材料的有效措施。范围大小是指长度或长度乘以宽度不小于某个尺寸，或者长度和长度乘以宽度在从多少到多少的大小范围内传递。生产单位可按尺寸要求供货。
凡产品尺寸（长或宽）在标准范围内，且不要求固定尺寸的称为不确定。不定长度也称为正常长度。按不定长度交货的金属材料，可在规定的长度范围内交货。例如，普通圆钢的长度不超过25 mm，长度在4-10 m之间的圆钢可以交货。
三。尺寸
按
烟台彩钢卷订单要求裁成固定尺寸称为定长。按固定长度交货时，所交付的金属材料必须具有订货合同中需方规定的长度。例如，合同中规定按固定长度5m交货时，所交付的材料长度必须为5m，小于5m或大于5m的为不合格。但实际上，交货长度不能超过5米，所以规定允许正偏差，但不允许负偏差。
4多尺
根据订单要求，将定尺切割成完整的倍数称为双直尺。按倍长交货时，交货金属材料的长度必须是需方在订货合同中规定的长度（称为单刻度）的整数倍（另加锯条）。例如，如果买方在订货合同中要求单根长度为2米，则切割成双直尺时长度为4米，切成三次时长度为6米。分别增加一个或两个锯。
标准中规定了锯切量。交货时只允许正偏差，不允许负偏差。
1. Range size of steel
It is an effective measure to save material to specify the range size of steel. Range sizing means that the length or the length multiplied by the width is not less than a certain size, or the length and length multiplied by width are delivered within
the size range from how many to how many. The production unit can supply products according to the size requirements.
2. Indeterminate (usually length)
Where the product size (length or width), within the scope of the standard, and does not require fixed size is called indeterminate. The indefinite length is also called the normal length. The metal materials delivered according to the indefinite length
can be delivered within the specified length range. For example, if the length of ordinary round steel not more than 25 mm is 4-10 m, the round steel with the length within this range can be delivered.
3. Sizing
According to the order requirements cut into fixed size is called fixed length. When delivery is made according to the fixed length, the delivered metal materials must have the length specified by the demander in the order contract. For
example, if it is specified in the contract that the delivery should be made according to the fixed length of 5 m, the delivered materials must be 5 m long, and those shorter than 5 m or longer than 5 m are unqualified. But in fact, the delivery can not
be 5m long, so it is stipulated that positive deviation is allowed, but negative deviation is not allowed.
4. Multiple ruler
According to the order requirements of the fixed size cut into a full multiple is called a double ruler. In case of
delivery according to the multiple length, the length of the metal material delivered must be the integral multiple of the length (called single scale) specified by the demander in the order contract (with additional saw). For example, if the buyer requires
a single length of 2m in the order contract, then the length is 4m when it is cut into double ruler and 6m when it is cut into three times. One or two saws are added respectively.
The sawing amount is specified in the standard. When delivery, only
positive deviation is allowed, and negative deviation is not allowed.
