Perforated Metal

Perforated metal or perforated sheets used in the Agricultural or Food Processing industry are used in a wide variety of applications and are available in a range of materials.

For example Stainless steel possesses many of the useful qualities needed for the food processing industry as it possesses good thermal capabilities, is corrosion resistant and ease of both fabrication and its’ maintenance make it a suitable choice for internal and external applications. Stainless steel perforated sheets and other materials are all available in a range of sheet thicknesses, hole sizes, pitches and shapes such as; round, slotted, square and bespoke.

Pre-Cleaning Screens

Perforated screens can be used in pre-cleaning and preparation to remove unwanted materials from agricultural crops including corn, flax seeds and other seeds, grains maize etc. Typically perforations used in these screens are round and slotted holes, however Graepels can work with you to create bespoke screens and solutions along with custom tooling for difficult specs so as to optimise your screening capabilities.

Cleaning and Screening

  • Pre Cleaning: Cleaning allows to reduce the time needed for milling improving the output and quality produce
  • Grain Cleaning: Screening allows for the removal of chaff, weeds, seed, rubbish, soil and straw or other unwanted materials
  • Screening: sifting and screening allows for the separation of unwanted materials such as weeds, seeds and other particles like stones.

Grain Drying Screens

At Graepels we offer our high quality screens in both galvanized and stainless steel. For drying screens it is important to use the right combination of perforation size and shape allows for optimal airflow and strength.

We ensure that all screens are high quality and allow for effective processing, through the design processes. We understand that design of a drying screen can effect the airflow which in turn effects the airflow rate and drying rate.

Our tooling and machinery enables us to create completely unique designs to meet your specifications specifications. So whether its, perforated screens for silo drying, or metal screens for floor drying, separation or grading screens we have the range and capabilities to ensure the best possible screens for every crop type to ensure you can increase your crop yields.
