About Us

Non-slip grating

Non-slip gratings are recommended above all where, for example, hazardous situations arise due to the influence of oils and greases as well as dirt or ice.

In many areas their use is mandatory. Neuhaus increases the non-slip properties with construction measures, specifically with differing recesses in the bear and/or cross bars. Neuhaus thus fulfils the “Determination of the Non-Slip Property” DIN 51 130. The process under this norm serves to test the suitability for the detection and evaluation of the non-slip property of floor covering, intended for use in work spaces and work areas with increased risk of slipping: Rooms and areas where for production or work reasons lubricating materials, e.g. grease, oil, water, food, food leftovers, dust, flour, plant waste regularly falls on the floor.

Walkways with tilts between 6° and 24° (excerpt from DIN 31 001)

It is recommended to equip sloped walkways in conveyor or similar systems with a tilt angle of up to 6° with standard gratings. Sloped walkways between 6° and 10° should be equipped with non-slip grating. With a tilt angle of 10° to 24° the slope should be bridged with steps. The distance between the treads and/or the measurements of the steps should be adjusted to the tread measurements.

Testing slip measurements (excerpt from DIN 51 130)

The temperature in the test chamber and the temperature of the shoes, lubricants and the tested covering must be 23 (+ 5)°C. Before starting the tests 100 (+1) ml of the lubricant is spread equally over the surface of the tested covering. The sole of the shoe is also spread with lubricant.

The tester walks upright forwards and backwards along the tested covering and looks downwards, taking steps of half a shoe length. The slope of the tested covering is increased from the horizontal position with a speed of 1°/s. The tilt angle at which the tester can no longer walk safely (acceptance angle) is determined with repeated raising and sinking at around the critical point. The acceptance angle of the tested covering is tested three times beginning with the horizontal position. Before the 2nd and 3rd test the lubricant is spread over the surface. The test is carried out by two testers.
