MOHN Stainless Steel Grating

Which type of mesh gratings is right for your process?

Not every product support structure fulfils the same function. The design influences product support, air circulation, potential grid imprints and – depending on the design – also cost-effectiveness for larger production runs.

That is why the four designs are compared directly with one another.

Corrugated Mesh grids made of stainless steel for food processes | Mohn GmbH

Grating / Grid with corrugated mesh

Characteristic Wavy Structure


Distinctive contact geometry. Depending on the product and process, a visible wavy pattern may result.

Stainless Steel Pressed mesh grid for Food Processing | Mohn GmbH

Grating/ Pressed-wire mesh grids

Straight product support


Of the three wire mesh options, this one offers the best conditions for minimizing the product's footprint.

Stainless steel welded mesh for food processing—cost-effective in batch production | Mohn GmbH

Grating/ Welded mesh-grids

Economically viable production runs

Robot-manufactured lattice structure. Economically viable for runs of 50 or more identical pieces, since setup costs are spread across the production run.

Bar grates made of stainless steel for food processing—large open cross-sections for air, smoke, and heat | Mohn GmbH

Grating / Grid with web bars

Particularly Open Design

Large open cross-sections for air, smoke, and heat; very little material is located directly beneath the product.

What effect does rust have on the product’s surface?

Product imprint

Product properties, weight, temperature, process duration and support geometry all play a part in determining the extent to which a rust structure can be transferred to the product.

WAVE GRID – textured product surface

WAVE GRID – textured product surface

Waves in the wires create a characteristic contact pattern. Depending on the product’s weight, composition and the duration of the process, this pattern may be visibly transferred to the product’s surface.

Advantages / Selection criteria

  • Customisable grate dimensions
  • Mesh sizes tailored to the application
  • Wire thickness and support struts according to load
PRESSED MESH – when the product’s surface finish matters

PRESSED MESH – when the product’s surface finish matters

The largely flat contact surface on the product side minimises a pronounced grid pattern. This makes the embossed grid particularly suitable when the final appearance of the product is of great importance.

Advantages / Selection criteria

  • Least visible imprint of all wire mesh variants
  • largely flat contact surface
  • For visually sensitive products
WELDED MESH – Cost-effective mass production

WELDED MESH – Cost-effective mass production

In the case of welded mesh, wires arranged in straight lines are welded together using robotic technology. From around 50 identical mesh panels onwards, this production method becomes particularly cost-effective, as the necessary set-up times are spread across a larger batch.

Advantages / Decision-making criteria

  • Robotic production
  • Economically viable from around 50 identical units
  • Reproducible series production
WEB BARS – open design for process air

WEB BARS – open design for process air

The support structure consists of stainless steel web bars or struts arranged in parallel. Large open spaces remain between the support elements to allow for the passage of air, smoke or heat.

Advantages / Selection criteria

  • large clear cross-sections
  • Reduced contact area with the product
  • also ideal for maturing processes

Web bar grid as a maturing rack for cheese

In the case of cheese products, product support and air circulation must be coordinated. The spacing and stability of the support can be adapted to the size, weight and firmness of the cheese in question. In this way, product support, air circulation and mechanical stability can be coordinated through the design.

Single, double or railing frames

Frame designs

The frame design is selected to suit the load, handling and product security requirements.

Single frame

Compact basic model

Perimeter framing of the lattice truss; support struts as required to ensure the necessary load-bearing capacity.

Double frame

For higher loads

 

Additional structural strength for heavy loads or correspondingly large or heavy products.

Balustrade frame

Edge protection & product protection

A raised edge to protect the edges and – depending on the product – provide additional lateral support to prevent slipping or falling.

Handle options

Depending on the application, the mesh trays can be supplied without a handle, with a straight handle or with a 60° angled handle. The choice depends on loading, unloading, the feeding concept and ergonomic handling.

Dimensions, mesh size and load capacity depending on the application

Customised design
Basic dimensions Width x depth x height to suit existing plant, trolleys and process systems.
Mesh sizes Commonly 25 x 25, 30 x 30 and 40 x 40 mm; other designs available on a bespoke basis.
Wire thickness No typical standard wire thickness. Design is deliberately based on the actual load.
Support struts Number and arrangement depending on grating size, product weight and total load.
Load-bearing capacity Each version is individually engineered – there is no standard load capacity.

Frequently asked questions about stainless steel grating

FAQ
What is the difference between corrugated mesh, pressed mesh and welded mesh?

Corrugated mesh has a corrugated structure, pressed mesh has a largely straight surface, and welded mesh has a straight, robot-weldable mesh structure.

Which grating leaves the least product mark?

Of the three types – corrugated mesh, pressed mesh and welded mesh – expanded metal offers the best conditions for minimising the visible imprint as much as possible.

What is the advantage of a web bar grid?

Large clear cross-sections facilitate the flow of air, smoke or heat around the product and reduce the contact area with the product.

Why are web bar grids suitable for cheese?

The spacing and stability of the support can be adjusted to suit the size, weight and firmness of the cheese; the open design promotes air circulation.

From what quantity onwards does a welded mesh become economically viable?

From around 50 identical lattice saddles onwards, robot-assisted production can make economic sense, as the necessary set-up times are spread across the production run.

What mesh sizes are available?

Sizes of 25 x 25, 30 x 30 and 40 x 40 mm are commonly used. Other mesh sizes are available depending on the product and process.

What wire thickness is used?

There is no standard wire thickness that applies across the board. The dimensions are determined according to the size of the grate, the weight of the product and the total load.

When is a double frame recommended?

Where the product’s weight, dimensions or the manufacturing process require greater mechanical stability or a higher load-bearing capacity.

When is a railing frame a good idea?

If edge protection or additional lateral product support is required, for example for meat or sausage products.

Which types of stainless steel are available?

1.4301 as standard; depending on the process and requirements, 1.4401 or 1.4571 may also be used.

Can wire mesh gratings be manufactured with a non-stick coating?

Yes. A suitable PTFE-based non-stick coating can reduce product adhesion and make cleaning and product removal easier.
