5 Must-Have Features in a dutch weave wire mesh

To initiate the industrial mesh buying process, you should reach out and supply the required mesh specification. This includes the length (rolled goods), dimensions (cut-to-size pieces), opening size, wire diameter, and weave pattern.

Dashang are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

• Here's a complete list of what you will need to get started:
  
  Manufacturer name/trademark
  Nominal wire diameter
  Nominal aperture size
  Weight (when applicable)
  Weave pattern
  Alloy
  Dimensions
  Required tolerances
  Order quantity
  Product label/technical data (for repeat orders)
  
  

While you may not know every specification you need, the more information you supply, the better we will be able to identify if your order fits our scope of work and calculate the logistics required to produce the mesh. Additionally, if you can supply samples of the wire mesh specification you wish to purchase, it can be reverse-engineered and recreated.

You should also provide information that accurately illustrates how the mesh will be used. This allows us to properly understand your needs and deliver a solution that resolves your concerns.

After reviewing your specifications with our engineering team, a quote reflecting all aspects of the order will be sent. If you accept the quote, the final step will be to submit a purchase order.

It's at this point that your mesh will begin being fabricated, with order confirmations, tracking numbers, and fabrication updates being sent to you.

How is Industrial Woven Wire Delivered?

The way in which woven wire mesh is packaged will vary depending on the manufacturer. That said, rolls and cut-to-size pieces are most often shipped in custom pallets.
With rolls in particular,  lengths of 25 or 30 meters, with half lengths of 12.5 or 15 meters are standard. NOTE: These standard lengths are expected to fall within +/- 10% of the invoiced length.

It is important to remember that partial lengths are available. But a roll cannot consist of three pieces, and each roll must reach at least 2.5 meters.

The width of the roll must be greater than the nominal width, up to 2%.

Cut-to-size pieces, of course, are made to order based on the sides, lengths, radi, and angles set by the customer. Regardless of the form factor, woven wire will arrive with a label containing the following information:

• Supplier name/trademark
• Nominal wire diameter
• Nominal aperture size
• Weave pattern
• Material designation
• Size
• Order quantity
  
  

What Will You Recieve With Your Wire Mesh Order?

When your woven wire order arrives at your facility, you should, in most cases, also receive the associated inspection documentation. Based on the amount of testing you mesh underwent, you can expect:

Selecting a micron wire mesh can be a daunting task. To better understand the complexities of mesh selection overall, let’s consider the more limited example of just choosing a 60-micron filtration mesh.  We will first discuss some of the variables in what you expect the mesh to accomplish, followed by a comparison of the ways of weaving different characteristics into the mesh, then conclude with ways an experienced mesh partner can avoid costly and wasteful pitfalls. 

When you call a micron filter mesh supplier and tell them you would like a 60-micron mesh, to recommend the right one they will have several questions. Some you may have anticipated and others you probably did not. 

Contact us to discuss your requirements of dutch weave wire mesh. Our experienced sales team can help you identify the options that best suit your needs.

• How much differential pressure will the mesh be subjected to?
• What is the desired volumetric flow rate through the mesh?
• How will the mesh be mounted?  Will it need a support structure?
• Will it need to be pleated, punched, or formed?
• Will the edges be welded, crimped, glued, hemmed, or over-molded with plastic?
• How will all this be implemented for manufacturability, accounting for material cost and availability?

After considering your answers to these questions, your mesh expert will consider a variety of nominally 60-micron mesh weaves and a few close matches.  They’ll think about which one’s unique characteristics would make it the most suitable one for your application.

Wire Mesh Weaves and Specifications

Square Weave Mesh

The first four on the list are what most people think a micronic woven filter is: a square weave, like the familiar bug screen, only finer.  In fact, square meshes that fine tend to be too fragile for most filtration applications.  Research shows that prior to reaching out to a mesh expert, only about 1-in-5 customers know that different mesh weaves other than square-weave exist. 

Dutch Weave Mesh

A variety of Dutch-weave meshes were developed to be more durable than square weaves for filtration.  A Dutch weave is one in which the warp wire is larger than the shute wire, and a reverse Dutch weave is one in which the warp wire is smaller than the shute wire.  With these weaves, the larger, more widely spaced wires add strength while tightly spaced smaller wires maintain the micron retention.  The complexity of these weaves means that predicting how easily fluid passes through the mesh is more complicated than just measuring the open spaces between wires.  Instead, flow resistance must be determined either by:

1. comparing flow rates of a sample compared to a calibrated standard, then calculating the pressure-drop coefficient for that mesh – or
2. by real-world measurement of the pressures on either side of the mesh in situ.

Wire Mesh Weave Comparison

Once a mesh’s micron retention and anticipated particle accumulation rate have been considered, the next step is to determine how much surface area of mesh is needed to meet the overall filtration requirements.  

Consider the Shape of your Filter and Filter Mesh

If the necessary surface area is less than space allotted for the filter, rolling, pressing, or pleating the mesh into a shape is necessary to increase the surface area for the filtrate to pass through. This means the manufacturability of the weave chosen needs to be considered.  Once formed, how will it be held in place? Will the filter need frequent cleaning?  Will it be cleaned by back flow, or by removing the filter from its housing?  Will it need to be welded to a support structure to facilitate that cleaning or to make removal practical? 

Some of the more robust Dutch weave meshes are too stiff for a pleating machine, whereas others are too thin for a welding machine.  One mesh might have a 1% improvement in flow rate but a 500% increase in cost.  

When it comes to selecting a woven wire filtration mesh, each of these factors and more are why early collaboration with a mesh filtration application engineer is an opportunity to sort the practical from the possible.

Partner with a Mesh Expert

Talking to a mesh expert about your 60-micron filtration needs, or any other inquiry you may have about wire mesh, will not just help you to avoid common costly pitfalls; it will get you the mesh that is optimal for the job instead of merely sufficient.
