 Whether used for technical or decorative applications, round hole perforations are the most frequently used in perforated products. Geometrically, a round hole is the most solid shape. 

Round hole perforations provide the possibility of a large open area and strength and comes in triangular, diagonal, straight or staggered rows and also with decorative holes.

Our perforated sheets with round hole perforations are used in many applications for example: 

Sieves  

• for agriculture (sieves for sorting/grading of seeds and stones)
• for the building industry
• for the recycling industry (sorting of bulk materials)
• Protection and ventilation sheets

Round holes are often used for acoustics and safety for the IT industry, as well as machinery construction for protection and ventilation panels.

Round holes offer a large ventilation opening with effective protection for the machine parts inside.

Facades

Round hole perforations offer an aesthetic decorative privacy shield and increases protection against the sun, and are also used for infill panels in balconies and balustrade panels.

Our vast experience as Europe’s largest producer and supplier of perforated products ensure we are your reliable and competent partner to process several types of raw materials.

 As with round holes, whether functional or decorative, perforated sheets with square holes can be used in many different ways. 

Square holes can be supplied with parallel rows, diagonal rows or staggered rows. In addition, square hole perforations allow a high open area for applications such as ventilation and guards.

Some examples of applications for perforated sheets with square hole perforation.

Safety and ventilation sheets  

• Ventilation and safety guards for the machine building industry
• Ventilation and security covers for computer server chassis

Facades

• Screens for defusing and sun protection
• Balconies and balustrades

Our vast experience as Europe’s largest producer and supplier of perforated products ensures we can produce these patterns in many different materials. 

Take inspiration offered by the number of perforation possibilities and be guided by our experts.

 Slot hole perforations can have either round ends or square ends (rectangular holes) and are typically used for sieves. 

Depending on the application requirements there are a range of slotted holes and patterns e.g. staggered or straight rows, herring bone and chessboard from which to select.

A few applications for slot hole perforated sheets

• Sieves for grain drying and sorting
• Malting floors (drying-kiln and germ-hutches)

Sieves for seed processing machinery are used in both the pre-cleaning and main cleaning of grain, maize, oil seeds, legumes, malt, rice, coffee and soy beans. The cleaning and sorting of seeds (malformed, discoloured, germinated, broken, contaminated with other species or mouldy grains in seed lots) can severely impact seed quality, viability and vigor and therefore the market value.

When used for this application DNT sieves achieve high quality cleaning and accurate sorting of seeds.

Sieves for sorting machines

Sieves for revolving screen machines

• Test sieves for grain according to DIN/ISO 3310
• Laboratory sieves with a high degree of accuracy

Food processing industries

• Fodder and grain mills

Recycling industries

• Separation
• Pellets and granulates production

DNT's screens for malting floors are manufactured to high quality standards giving reliability and effectiveness. For all processes, from drying-kiln to germ-hutches, perforated sheets incorporating slot hole perforation are predominantly used. 

Brewery and Winery/Others

• Malting floors made of steel and stainless steel for malt processing technology
• Sieves for press houses and presses
• Sieves for paring and polishing rice
• Rope belt conveyers
• Decorative applications 

 Achieve high open areas with hexagonal perforation from DNT. 

Maximum ventilation

The need for effective cooling is increasing for many technical products. Flexible solutions and innovative products like our hexagonal perforation patterns are the answer.

Our hexagonal perforation provides an extremely high open area of up to 85%. Sheets with holes of this configuration are very lightweight. The stability of the parent material is of the utmost importance to maintain the shape of a honeycomb structure. This pattern produces an appealing, timeless design suitable for current and future product applications.

The ability to control airflow can be used not only for cooling, but also the opposite effect using a targeted heat supply. 

IT

Whether it is racks or server cabinets the heat developed from the integrated systems and components must be removed to the outside efficiently, which is usually achieved by using internal fan modules. A sheet with a hexagonal perforation provides a very large open area giving optimal ventilation. Thanks to the high air flow, temperatures can be kept constant in the cabinet, whereas the other areas of the cabinet can remain obscured by non-perforated areas and are therefore protected.

Automotive

The need to cool heat producing parts of machines and engines e.g. tractors and other vehicles is a traditional application for perforated sheet metal products. Depending on the chosen open area, the heat can either be dissipated or be re-circulated. Small hexagon perforated sheets can also be used as protection against insects in the engine compartment.
