Domestic cement concrete flatness is usually measured by the ruler method, the current standard is 2m / �� 4mm. Using this method each measurement are different values, and can not respond to the ground level of the overall level of error, so gradually replaced by the international F numerical norms. The F values ??are the American Concrete Institute # 117 and the Canadian Standard Association # A23.1 for the specification and measurement of concrete floor heights and heights. This specification includes two F values: FF for the flatness, FL for the high difference, the flatness of the relationship between the floor of the uplift and depression, a high difference between the floor of the tilt or height difference.
With the modern logistics, workshops, supermarkets and other stores on the ground flatness and level of the requirements of the ever-increasing, the concept of ultra-flat floor was born. For example, only the excellent flatness of the ground, unmanned machinery and equipment can be detached from the track constraints, precision movement anywhere; the ground level difference is smaller, more than 8 meters high shelf is more difficult to dump.<a href="http://doublesteelroller.com">Double Steel Roller - Road Machinery Equipment Manufacturers - Doan Machinery</a>
