Safety
The theme of health and safety at work and accident prevention is growing in importance in companies and institutions. The accident prevention regulations issued by the Professional Associations and the German Social Accident Insurance (DGUV) are binding legal regulations, so that non-compliance can have serious consequences for any company. In many cases, avoidable accidents at work cause significant costs. A serious corporate commitment to pleasant and safe working conditions has an effect not least on the image of a company and enables customers to draw their own conclusions of the quality of the products and services. Irrespective of all legal consequences, all costs and the damage to our reputation, there is one thing above all that we should not forget: we owe our success to our employees - people who are worthy of our protection.
These are all good reasons for MEISER dealing in depth with this topic. We have developed a range of products which help you to prevent accidents and carry out your work safely.
We have brought these products together in our catalogue called „Health and Safety at Work“ in order to show you at a glance where improvements are possible and required.
Ask your contact at MEISER for advice and carry out an analysis together with us with respect to how you can design your work areas to be even safer. Detailed information can be found in the MEISER health and safety at work brochure.
Slip protection serration types
Pointed Tooth Serration SR 1
The pointed tooth serration is used exclusively for press welded grating. In this form, the bearing bar is provided with particularly sharp notches by arranging crescent-shaped recesses continuously next to one another. This significantly increases the slip-resistant properties of this type of grating. With this profile it is possible to achieve slip resistance class R12 with certain mesh widths.
Saw Tooth Slide Serration SR 2
Saw tooth slide serration is only possible in the case of press locked grating and is characterised by the saw tooth-shaped notching of the bearing bars and/or cross bars. With this form of slide protection, the maximum slip resistance class that can be reached is R12. This slide protection profile forms a basis for other special forms in accordance with foreign standards (e.g. Danish Railways). Please contact us about this if required.
Super Slide Serration SR 3
Super slide serration is only possible in the case of press locked grating and is characterised by extremely high levels of anti-skid-properties. Here, the bearing bars and cross bars are punched to be particularly sharp-edged. With this form, the highest resistance class, i.e. R13, can be reached. This type of serration is used particularly in the food industry and in areas with high levels of contamination or regular contact with liquids.
Standard Slide Serration SR 4
The standard slide serration is characterised by the semicircular notching on the bearing bars and/or cross bars, with residual webs being left between the notches. This means that in the case of press locked grating, a slip resistance class of up to R12 (notching of the bearing bar and cross bar) and in the case of press welded grating up to R11 (notching only possible on the bearing bar) can be achieved. This version is used as the standard grating in outdoor areas which are regularly frequented and accessed.

Slide protection - serrating is to be found on bearing bar, cross bar, edge surround. Other sizes are possible based on the above. For production reasons, not all types of slide protection can be provided for all mesh spacing or bearing bars.
We will be pleased to advise you!
In recent years the issue of the slip resistance of walkable surfaces has gained in importance. Wherever work is carried out with glide-enhancing substances, i.e. where oils, greases and emulsions are used, there is an increased risk of slipping.
Outdoors, the weather plays a crucial role. Rain and snow quickly transform many areas into slides. However, MEISER offers a solution to this problem and guarantees a safe grip with MEISER anti-skid grating.These greatly reduce the risk of slipping. Depending on the regulations or personal safety needs, MEISER can supply grating with a classification from R9 to R13.
The required R number for different fields of application is specified by the „Professional Association Rule for Safety and Health at Work (BGR181)“. An analysis of this slip resistance capability is carried out by an independent test institution with clearly defined test equipment.
Classification
| DEGREE | R CLASS |
|---|---|
| from 3° to 10° | R9 |
| from 10° to 19° | R10 |
| from 19° to 27° | R11 |
| from 27° to 35° | R12 |
| more than 35° | R13 |
