At JAERA you have the choice between two main embossings: duett Chequer plates and quintett Chequer plates. Both variants offer high slip resistance and are ideal for industrial applications. The main difference lies in the number and arrangement of the warts on the plate surface.
The duett Chequer plates are characterized by two elongated warts per structural unit, which are arranged offset to each other in the block. This Embossing-depth offers a good combination of stability and slip resistance.
The quintett Chequer plates has five tapered warts per structural unit, which are arranged in a staggered check pattern. Due to the higher number of protrusions, it offers even better slip resistance and is therefore often used in areas that have to meet particularly high safety requirements.
Do you have any individual wishes for your warted sheets? We are happy to implement these in our further processing service.
You are welcome to enquire about which further processing options can be implemented for your product.

Here you will find all the important information about warp plates.
Warp plates, like checker plates, belong to the group of corrugated plates and consist of robust aluminum metal plates. They are characterized by a surface structure with wart-shaped elevations that are evenly distributed across the sheet.
These warp patterns ensure increased slip resistance, as liquids can drain away quickly and the formation of puddles is prevented. This significantly reduces the risk of people slipping and objects adhere securely to the surface. The wart structure also ensures that slipping movements between the shoe profile and the warts are minimized due to increased friction. Wart plates are therefore ideal for industrial applications where safety and stability are crucial.
Warp plates are used in many areas thanks to their non-slip and robust properties. They offer a wide range of applications, both in industry and in vehicle construction and building.

Warp plates are mainly made of aluminum, as this Material is light and easy to process.
Chequer plates Alu is produced using a rolling process in which the characteristic surface structure with raised warts is embossed into the aluminum. The sheet is passed through special embossing rollers that press the wart pattern (e.g. duett or quintett) into the surface.
This process can be carried out by cold or hot rolling, depending on the thickness of the sheet. After Embossing-depth , the checker plate is cut to the desired dimensions and, if necessary, further processed, e.g. with an additional surface treatment to protect against corrosion.

The term chequer plate can be used synonymously with Chequer plates and tear plate, with chequer plate acting as a generic term that refers to the ribbed surface texture of these sheets. The other two terms are derived from the shape of the protrusions.
Chequer plates are usually made of aluminum and have elongated, pointed protrusions known as tubercles. These lugs are arranged in rows parallel to each other, with each row offset at a 90-degree angle to the next. Common variants are the duet plate with two lugs and the quintet plate with five parallel lugs.
Tear plate is characterized by individual oval elevations that are arranged diagonally to each other. These sheets are mainly made of steel or stainless steel. A widespread variant is the Mandorla sheet, whose name is derived from the almond-shaped structure of the protrusions.
The slip resistance of Chequer plates is assessed according to the DIN 51130 standard, which classifies floors in work areas with an increased risk of slipping. Chequer plates, especially in industrial and commercial applications, are often classified according to these slip resistance classes to ensure that they meet the required safety standards. The slip resistance classes range from R9 (low slip resistance) to R13 (very high slip resistance).
Tabular overview of slip resistance classes:
| Slip resistance class | Tilt angle | Field of application |
|---|---|---|
Slip resistance class R9 | Tilt angle 6-10° | Field of application Low risk of slipping, e.g. in private living areas |
Slip resistance class R10 | Tilt angle 10-19° | Field of application Moderate risk of slipping, e.g. in offices, warehouses |
Slip resistance class R11 | Tilt angle 19-27° | Field of application Increased risk of slipping, e.g. outdoors, in workshops or commercial kitchens |
Slip resistance class R12 | Tilt angle 27-35° | Field of application High risk of slipping, e.g. in industrial production areas |
Slip resistance class R13 | Tilt angle >35° | Field of application Very high risk of slipping, e.g. floor coverings in slaughterhouses |
