How To Specify Wire mesh
In order to request a quote or order material, it is essential to identify your complete wire mesh specifications. Please find below the seven key criteria needed to request a quote or to place an order with Darby.
- Quantity – how many pieces or rolls do you require for your application? Do you need 1 roll, typically 100 feet, or 1 piece cut to 50 feet long? Do you need 3 pieces cut to size, each piece 8 feet in length? Do you require 1000 discs 7.25″ diameter? Or 50 pieces cut to 4 foot by 10 feet.
- Dimensions— what are the dimensions of the roll or piece you need? Rolls, which typically measure 100 feet in length, are often available in widths: 3 foot, 4 foot, and 5 foot. If you require cut pieces, do you need 1 piece, 4 foot by 12 foot, 6 pieces, 2 foot by 4 foot, or 48 pieces, 1 foot by 1 foot? If your requirement needs custom manufacturing, will 30″ by 72″ pieces fit your template or frame?
- Mesh (Mesh Count) — first, measure 1″ (from center to wire to center of wire), then count the number of openings in that 1″ span. This number is your mesh, or mesh count. If you require a space cloth, what is the clear opening (in inches) between parallel and adjacent wires?
- Diameter Wire—what is the diameter of the wire you need, in inches? Often times a micrometer, a specialized instrument which measures diameter is used. If you happen to know your mesh count, and you’re a bit unclear in terms of the diameter wire, the standard or market grade meshes are an excellent starting point.
- Metal or Alloy— what metal or alloy will work best in your application?
- Type of Weave— do you requirements call for a plain weave? Or is it a twilled weave? Do you need a welded wire mesh specification?
- Type of Crimp— if your requirements call for a woven mesh, there will need to be a crimp style. Is it a plain crimp, intermediate crimp, lock crimp? A hybrid crimp style? Plain crimp is considered the most common.

Darby & Son, Inc. needs to be given the seven criteria as detailed above.
If you are unsure about what mesh to use, we recommend purchasing samples or prototypes or contacting an expert—engineering or otherwise—in your field for more tailored advice for your application.
Shipping Information
How does wire mesh ship?
Unless otherwise stated, pricing does not include shipping costs, and delivery is considered FOB Origin. Origin includes our Philadelphia, PA warehouse or any of Darby’s mills.
The shipping method is determined by what is ordered and how much of it is ordered. Edward J. Darby & Son, Inc. stocks over 2,000 different industrial wire mesh specifications, not including our ability to custom manufacture almost any requirement. To adapt to this wide array of inventory and custom manufacturing options, Darby offers two primary shipping methods—UPS and Motor Freight.
A significant portion of the thousands of wire mesh orders that we ship each year are via UPS. UPS is our preferred carrier and with good reason. They offer competitive pricing, responsive service and excellent convenience for our customers. Additionally, Darby is a daily pick up for UPS, and just 6 miles from their terminal, allowing us to get our mesh to you faster than many other options.
UPS does, however, have specific weight and size restrictions for packages that our mesh shipments must adhere to:
- Packages can be up to 150 lbs.
- Packages can be up to 165″ in length and girth combined.
- Packages can be up to 108″ in length
- Packages with a large size-to-weight ratio require special pricing and dimensional weight calculations. (Source www.ups.com)
UPS shipping costs are determined by the destination zip code as well as the weight and size of the shipment. UPS also offers expedited services, including next day and second day delivery.
If a shipment exceeds any of these requirements, an order must ship via LTL Motor Freight Carrier.
LTL (Less-than-Truckload) Carriers are used in the instances when material is too heavy or too large to ship via UPS. Some of the more recognizable carriers include: Fed Ex Freight, UPS Freight, Pitt-Ohio, Con-way (CCX), and Yellow-Roadway (YRC). Shipments requiring LTL Carriers are often packaged on a pallet or placed into a crate (ideal for fragile shipments), and in many cases, require a lift gate, fork lift or pallet jack to unload.
Like UPS, LTL Carrier pricing is based upon the destination zip code as well as the weight and size of the shipment.
LTL Carriers prefer to deliver material to a commercial or business address, as opposed to a residential one. Citing the special services required in handling a residential delivery, including setting up an appointment and utilizing a truck outfitted with a lift gate, LTL Carriers often impose extra charges for these deliveries. Should a customer require a residential LTL delivery or any other type of special delivery (correctional facility, farm, church, jobsite delivery, etc.) it is critical that the customer inform us of these requirements before your order ships. Please keep in mind the decision of a delivery location is made solely by the carrier and applies to both UPS and LTL shipments.
From time to time, Edward J. Darby & Son, Inc. does handle other types of shipments including: international air freight shipments, truckload shipments and courier services. Please contact us with your requirements for more information.
How can shipping costs be kept to a minimum?
Darby realizes the importance in keeping your costs down. We constantly negotiate with these carriers to make sure pricing is competitive and in-line with the marketplace. We also take the necessary precautions to avoid extra shipping charges imposed by a carrier by packing material as efficiently and economically as possible.
As previously mentioned, LTL motor freight carriers often impose a surcharge for extra services required with a residential delivery. It is important to discuss with Darby’s shipping administrator or sales person various options that seek to minimize these charges. For example, many freight companies offer a terminal pick up, which can eliminate residential delivery fees.
We also offer pick-up at our facility for local customers. Please be sure to discuss this with your sales person or shipping manager. Your order must be pre-scheduled to ensure your order is ready. Directions to our Philadelphia, PA facility can be found here.
Finally, most parcels that ship FOB: Origin ship “prepaid and add.” This means that the shipment cost will be added to your transaction. Should you have a UPS account or an account for a preferred motor freight carrier, please let us know and we can ship your parcel out accordingly.
How long will delivery take?
Assuming a customer opts for standard and non-expedited delivery, the number of days in transit will depend on your location. The maps below illustrate the standard days in transit for shipments that originate from Philadelphia, PA 19133:

Pricing Information
Pricing in the wire mesh industry can be both confusing and volatile. By and large, because the wire mesh market is closely linked to the metals market, pricing for wire mesh can be impacted by fluctuations in the value of copper, nickel and iron. Further, because there are so many different specifications and countless ways in which mesh can be purchased, pricing for wire mesh is not always straight forward. We have developed the following section to help resolve some of these common pricing related questions.
More Information About Pricing
Plastic extrusion, pharmaceutical drugs, roadways, and high-rise apartments. These are just a few of the many industries that thrive when mesh is properly integrated.
With dozens of mesh solutions, such as woven wire mesh and welded mesh, on the market, it’s up to the engineers, project managers, and lab technicians to select the right one.

But which material works best: welded mesh or woven wire mesh?
“What will the mesh be used for? What material am I working with? When do I need the mesh?” are all questions you must ask yourself when determining whether to use welded mesh or woven wire mesh.
W.S. Tyler has been a leading wire mesh manufacturer for over 140 years and are here to ensure you integrate the right mesh solution.
This article will establish what welded mesh and woven wire mesh are, how each material is made, what they are used for, and how they compare in cost. At the end, you should have a better understanding of which mesh will work for you.
What Is Woven Wire Mesh?
Woven wire mesh is best described as a predetermined number of metal wires interlaced together to form a roll or sheet of wire cloth that upholds a specific pattern. When weaving wire mesh, parameters such as wire diameter, opening (aperture) size, micron rating, weave pattern, width, and length can be customized to your specific needs.
How Wire Mesh Is Made
When woven wire mesh is woven, a designated amount of wires are wrapped around a warp beam that gets placed into a specialized weaving loom. The warp wires are then placed into heddle frames that split them into 2 or more sets depending on the weave/pattern of the mesh.
As the loom operates, the heddle frames push the different sets of wires up and down as a wire, known as the shute wire, is driven in between the wires. After being threaded through the wires, the up and down motion of the heddle frames locks the shute wire into place.
Woven Wire Mesh Applications
One advantage woven wire mesh has over welded mesh is that the mesh opening can be much finer. This is because as the wire diameter gets smaller, the harder it is to weld the mesh without damaging the wires or compromising the openings of the mesh.
Having said that, the finer mesh openings of woven wire mesh make it perfect for virtually any filtration, particle analysis, or screen printing application.
What Is Welded Wire Mesh?
Welded wire mesh is a series of steel wires that are welded at the wire cross-sections using one of several welding techniques, most commonly TIG and spot welding. As the wires undergo a thorough welding process, the opening size of the mesh is, for the most part, permanent.
How Is Welded Wire Mesh Made?
When welded wire mesh is made, spools of wires are threaded into a weld mesh machine, much like threading wires into the heddle frames and reed of a woven wire loom. Separate spools of wire are then fed through a straightener and pre-cut to match the desired width of the mesh.
As the machine runs, the wires from the spools are fed through the machine. The pre-cut wires are then placed into a mechanism that lays them across the wires being fed from the spools.
After being laid in place, the machine applies a uniform weld at each cross-section simultaneously. Depending on the length of the welded wire mesh panel, the mesh is made available in welded wire mesh rolls or operators take the mesh, cut the access material, and place it into piles of cut-to-size pieces.
Welded Wire Mesh Applications
As thicker wires must be used to withstand the welding process, welded wire mesh is regarded as being the more rigid and durable of the two materials. This heightened strength makes it perfect for perimeter fencing, protective caging (animals and equipment), and concrete wire mesh sheets.
How Does Cost Compare Between Woven and Welded Wire Mesh?
As illustrated previously, welded mesh and woven wire mesh are produced differently. That said, other than the threaded wires throughout the loom, the weaving process of woven wire is mostly automated.
Producing welded mesh, on the other hand, is a lot more hands-on. An operator must thread wire through a straightener before it is cut into the crossbars.
Additional wire must also be threaded through the machinery itself.
Now, the mechanism that accurately places the crossbars must constantly be fed material. These bars are commonly fed by hand.
Lastly, the access material that protrudes off the edges must ensure optimal results. Again this process is commonly done manually when the mesh is not being rolled by the machine.
With that, the labor costs and heavy-duty wire that must be used causes welded mesh to be the more costly of the two.
Which Mesh Is Right For Me?
As with all mesh solutions, the application will determine whether you should use welded mesh or woven wire mesh.
If you are working with rugged material that requires a mesh that is sturdy and durable, welded wire mesh may be a good fit. Welded mesh is also a good fit for extremely corrosive conditions as it can be galvanized for extra protection.
If mesh strength is not an issue and you’re looking for a cost-effective mesh solution that can offer smaller mesh openings than ¼” for filtration purposes, woven wire mesh is right for you. As woven wire mesh is produced predominantly with stainless steel, which is too resistant to corrosive material, the fact that it often has shorter lead times than welded mesh should also be considered.
Implement the Ideal Wire Mesh Specification
At first glance, woven wire mesh and welded may seem identical, however, they are two materials that carry a lot of differences. That said, no matter which mesh you chose to implement, knowing the right mesh specification is just as important as the material itself.
Woven wire mesh is a series of wire interlocked together during the weaving process and is ideal for filtration, particle analysis, and screen printing.
Welded mesh is a mesh sheet that is welded at each cross-section and is ideal when heavy-duty mesh openings are needed.
Having worked with woven wire mesh for over 140 years, W.S. Tyler has the know-how needed to ensure your mesh solution properly process your material.
