Negresco Product Story

Reproducing some of the finest marbles including Calacatta, Grandi Marmi uses cutting-edge technology to offer a precise marble finish in a highly versatile format. Due to its scale, Grandi Marmi is suitable for rooms with higher ceilings and larger areas of floorspace, while the 6 mm thickness means it can be incorporated into a vast array of fabrication pieces. Grandi Marmi also features a continuous veining design, which spans across multiple panels and can also be provided in Bookmatched panels for use within hotel lobbies and entrance halls or for creating that spectacular feature wall. With Polished, Honed and Natural finishes, Grandi Marmi is the most flexible dressing for any internal space. Negresco is part of our  Marble-effect  Collection.

Ramp Test Values (DIN 51130)

Understanding Ramp Test Data

DIN Standard Ramp Testing (DIN 51130) is an alternative to Pendulum Testing and generally categorised as an 'off-site' activity because of the size and complexity of the equipment required to carry out the test. The Slip Resistance Values (RSV) are factory gate values (based on supplied tiles) and categorised using the Ramp Test (DIN 51130) method which is commonly used by European factories. In this method, a lubricated inclined platform is adjusted to a gradually increasing gradient, and the angle is measured at which a person walking on it slips.

We have deliberately not included the ramp test angles on this page as this information can be confused with the angle that a floor may be safely set to, which is incorrect. The shod test results are quoted as an R Rating value from R9 to R13, which relates to the ramp angle.

R Rating ValueFriction
R9Minimal
R10Normal
R11Good
R12Good
R13Very high

See the Health and Safety Executives website for more information regarding the Ramp Test procedure. Ramp Test Certificate available on request.
