Film about the production and processing of perforated metals using our laser system

Perforated plates are invaluable in various industries due to their exceptional adaptability. They consist of metal plates that have been perforated by machine or manual processes. The perforation patterns can be standardized or customized, depending on the customer's specific requirements. The properties of perforated sheets make them ideal for applications where air circulation, sound insulation, filtration, decoration or mechanical strength are required.

A key advantage of rotec is our extensive Perforated sheet-warehouse in Berlin. With over 1000 different varieties, we have one of the largest selections in Germany and are therefore able to meet even last-minute requests without any problems. This extensive stock makes it possible for your Perforated sheet-orders are processed and dispatched as quickly as possible. Our philosophy "The fast eats the slow" shows how important speed and efficiency in processing and delivery are to us. Whether you need standard products or customized Perforated sheet-solutions - with us you are always on the safe side.

The standard DIN 24041 specifies the geometric requirements and dimensional tolerances for Perforated plates is defined. It defines the standards for hole diameters, hole spacing and hole arrangement and ensures that perforated sheets are manufactured to a consistently high quality. This standard is particularly important for applications where precise perforation and even distribution of holes are required, for example in architecture or in technical applications such as filters and screens. By complying with the DIN 24041 can Perforated plates can be precisely adapted to specific requirements and produced in a repeatable manner. At rotec, we ensure that all perforated sheets manufactured by us meet the requirements of this standard and therefore satisfy the highest quality standards.

The use ofperforated medallions has a long history and developed with the progress of industrial manufacturing techniques. Originally Perforated plates produced by manual punching, whereby metal plates were perforated with hand tools. These processes were labor-intensive and time-consuming. With the introduction of machine punching technology in the 19th century, the production of Perforated sheets revolutionized. Mechanical production made it possible to produce large quantities, which considerably expanded the range of applications.

Over the last few decades, the technology of Perforated sheet-production through the use of CNC-controlled machines, Laser cutting and state-of-the-art coating methods. These advances have led to Perforated plates can now be manufactured more precisely, efficiently and flexibly, which has significantly expanded their potential uses in various industries and design applications.

Our punching machines are equipped with CNC (Computerized Numerical Control) technology, which enables precise control of the punching processes. The machines can produce different hole patterns in different shapes and sizes, with a repeatability that would be impossible to achieve manually. This is particularly important when it comes to large production quantities or customer-specific orders where the highest precision is required.

Laser cutting technology

For more complex shapes and smaller holes, we rely on laser cutting technology. Lasers make it possible to cut extremely precise holes in the material without damaging or distorting the sheet metal. The use of lasers is ideal for thin sheets in particular, as they ensure sharp edges and clean processing.

Hole diameters and sheet thicknesses

An important factor in the production of Perforated panels is the diameter of the holes and the thickness of the material. Depending on the application, we can produce holes in different diameters, from microscopic holes for filter applications to larger holes for decorative or structural purposes. The thickness of the sheet also varies, with us offering both thin sheets for lightweight applications and thick, robust sheets for industrial purposes.

Our Perforated plates are available in different hole shapes and materials to meet the specific requirements of different industries. Here is an overview of the most common Perforated sheet-types and their possible applications:

• Round perforated sheets: Probably the most common type of Perforated sheetperfect for ventilation systems, acoustic applications or mechanical applications where uniform ventilation and stability are required. Round perforated sheets are often used in air conditioning systems, machine cladding or as sound insulation.

• Square perforated sheetsThese Perforated plates are ideal for decorative applications, but also for filtering and screening systems. Thanks to their uniform arrangement of holes, they are often used in architectural façades or as a design element in modern construction projects.

• Slotted perforated sheetsThese sheets offer greater permeability and are often used in filtration systems or for drainage. They are also used in the automotive industry. Slotted perforated sheets are often used, for example for the ventilation of engine covers or as exhaust air systems.

• Special perforationsIn addition to the standard shapes, we also offer individual perforation patterns, such as hexagons, triangles or complex ornaments. These special perforations are often used in artistic installations, design facades or as aesthetic partition walls in interior design.

The production of perforated sheets at rotec comprises various work steps that are carried out by high-precision machines to ensure that each product exactly meets our customers' requirements. From the basic processing of the material to individual finishing, we offer you everything from a single source.

1. perforating and punching: precision in the hole pattern

The first step in the production of a Perforated plate is the perforation or punching of the material. With our modern punching machines, we can precisely create various hole patterns in the sheet metal. This is done either by punching a predefined pattern or by creating a customized hole pattern based on the specific requirements of the project.

2. cutting: Precise cutting to size

After the Perforated sheet Once the desired pattern has been applied to the fabric, it is cut to size. Thanks to our laser cutting technology, we can produce cuts that are accurate to the millimetre and exactly match the dimensions of your project. This precise technology enables us to cut even complex shapes without damaging the material or compromising its stability.

3. bending and edging: Perforated sheets in any shape

Depending on the application Perforated panels often be formed into specific shapes. Our bending and edging technology makes it possible to Perforated sheet into almost any shape - from simple angles to complex geometries. Whether for railings, façade elements or cladding - by bending and edging, the Perforated sheet perfectly into your designs.

4. surface finishing: protection and aesthetics

To extend the service life of our Perforated plates and improve their appearance at the same time, we offer a variety of surface finishes. Powder coatings in all RAL colors are particularly popular, not only protecting the material from the elements but also giving it an attractive appearance. These coatings are particularly robust and durable, making them ideal for outdoor applications.

Perforated plates are used in many different industries, from architecture and mechanical engineering to the automotive industry and store fitting. Here are some specific examples of industry-specific applications:

Architecture and construction

In modern architecture Perforated plates are playing an increasingly important role. They are used as façade elements, Sun protection systems and claddings. Thanks to their versatility in design and function, they can be Perforated plates can be used as an aesthetic design element that also provides functional protection, such as in the case of Weather protection grilles or privacy screens.

Automotive industry

In the automotive industry Perforated plates often for technical components such as Ventilation systemsengine covers and protective covers. The high strength of metalPerforated sheets combined with their lightness makes them ideal for use in vehicles where weight savings and stability are crucial.

Food and chemical industry

In the food and chemical industries Perforated plates are frequently used as filter and sieve systems. Due to their precision and corrosion resistance, especially when using stainless steel, they are ideal for processing liquids and solids.
