Floor Construction - Floor Flatness - Floor Flatness Specifications

Floor Flatness Specifications

The US, UK & Germany are currently the only countries to have developed measurement standards to any degree of sophistication. There is a substantial amount of commonality between the US and UK standards and of which can found in use throughout the world. This is contrary to the German standard which is unlikely to be seen outside of Germany and other parts of Europe.

The decision on which specification to adopt is normally determined by the country of origin/influence and there are four main floor flatness specifications used internationally
.

In addition, there are two basic types of floors:- 

Free Movement Floors 
Free movement floors refer to areas where materials handling equipment operates in random, non-defined directions and have an infinite number of travel paths.

Defined Movement Floors 
Floors in very narrow aisle racking systems have materials handling equipment that run in defined & fixed paths between the racking, such as very narrow aisles.

What is Superflat?

The Superflat specification was the most stringent of all the UK TR34 VNA specifications. It has now been superseded by the TR34 defined movement specification, is now the same as the European recognised specification EN 15620.
  
A Defined Traffic path takes place when material handling equipment moves up and down the floor in exactly the same wheel position each time. Very Narrow Aisle (VNA) warehouses are most commonly applied for defined traffic specifications.

The TR34 4th Edition / EN 15620 specification considers all wheels of the VNA forklift truck. This is a vast improvement on alternate specifications which do not consider all wheels.
