Strand Count, Mesh Size, Hole Size and Angle
Some products may require a perfectly square configuration, while others may need a rectangular hole shape. Large, medium or small, Conwed is ready to work with you to find the netting design that makes your project a reality.
Strand Count is the number of strands observed in a given length in that direction. It is typically reported in “strands per inch” or “strands per 10 cm”. For example, machine direction (MD) strand count would report the number of machine direction strands per inch or per 10cm.
In square netting, strand count is typically reported MD first and CD second as this strand geometry follows a perpendicular configuration in machine and cross directions. Example: 1 x 1 strands / inch or 3.93 x 3.93 strands / 10cm
However, in diamond netting there are no MD or CD strands per se. Due to the fact that diamond netting is formed with strands at an angle, on opposite directions, one on top of another, the strand count is reported in top and bottom strands. Example: 3.2 x 3.2 strands /inch or 12.59 x 12.59 strands / 10cm
In cylindrical extruded products, machine direction (MD) strand count is reported in strands per circumference of the tube. The cross direction (CD) strand count reports the number of CD strands found per inch or per 10 cm. Strand count is the most common netting characteristic we utilize to identify potential netting configurations for your application.
Mesh Size is the distance from the center of one strand to the center of the next strand in that direction. It is typically reported in inches, millimeters and centimeters. Standard reporting lists machine direction (MD) x cross direction (CD) measurements. Example: 1” x 1” or 25.4 mm x 25.4 mm
Hole Size is slightly different than Mesh Size. It is the distance from the strand’s inner edge to the next strand’s inner edge in that direction. Not as commonly used as Mesh Size, this measurement is helpful when different thicknesses and geometries are required. It is also reported in inches, millimeters and centimeters.
It is measured in degrees and it indicates the angle of the strands that form the netting configuration. Square netting has a 90° angle and diamond netting can vary depending on the requirements and final application.
Weight and Thickness
Conwed™ Netting can be configured to match weight targets. With all other variables remaining constant, as netting weight increases, the product strength, thickness and roll diameter increase while the strands get bigger. Conversely, as the product weight decreases, the variables mentioned before also decrease. Nevertheless, there are many plastic resins that behave differently and provide a wide range of properties that allow for affecting some variables while limiting the effect in others.
WEIGHT MEASUREMENT – Typically reported in pounds per 1,000 square feet (PMSF) and grams per square meter (GSM).
Conwed™ Netting thickness could also be referred to as “height.” The thickness of the netting is intrinsically related to the weight. In general terms, the heavier the netting configuration, the thicker the strands. Conwed has developed certain exceptions to this rule by creating
netting configurations where weight remained constant and selected strands had a customized thickness. This is just an example of our technology capabilities and our ability to tailor our products to fit the final application.
THICKNESS MEASUREMENT – Usually reported in length measurements such as inches, mils and millimeters.
Conwed offers a wide range of color alternatives to manufacture your preferred netting design. Pelleted plastic resins offer a vast assortment of color choices and we can work with you to find the most suitable options for your final product application.
In general, the most common colors used in our standard netting portfolio are natural, black, white, and green. Many of our customers respond to industry and market trends when selecting the right color for their netting component. As an example, in the erosion control
industry, some colors help installers easily identify the type of product, degradability, and
application when applying blankets or turf reinforcement mats in exterior locations.
AESTHETICS & SPECIAL EFFECTS
Color is also important when netting will be visible in the final product. For example, our elastomeric netting in hygiene and medical products is highly preferred in natural or white tones rather than other solid colors because it blends with the final product. Conwed can also explore special effects such as glow in the dark, color response to changes in temperature and light, metallic finishes, pearlescent or nacreous coatings, etc.
Conwed™ Netting is formed by consistent integral joints that create a durable web structure. The standard netting configuration has joints that seem to be slight protuberances where strands in opposite directions collide. However, Conwed is able to modify the netting joints along with other characteristics to fit the final product application.
Requesting special netting designs with dense, thin or flat joints may be triggered by convenience reasons. For example, some plastic fence users may require flat surfaces to avoid injury during shipping, handling and installation. In other instances, netting with thick
joints help separate materials or protect objects. The oil & gas industry utilizes Conwed™ Netting with heavy and thick joints to safeguard pipelines as the joints help absorb impact of uneven backfill.
The filtration industry is a highly technical industry with strict performance targets and ongoing innovation. Conwed™ Netting joints actually deliver flow channel gapping in separation applications, improving filter efficiency. Unusual designs may even combine low and high joints to target specific functionalities in new generation product
We customize each netting configuration to deliver the necessary strength and resistance you need. The chemical formulation of the netting determines the softness, brittleness, strength and roughness of the final configuration. Our engineering team can collaborate
with you until the right formula for your final application is identified.
WHY IS TENSILE STRENGTH IMPORTANT AND HOW IS IT MEASURED?
It measures the force required to pull the netting to the point where it breaks. It is usually displayed in units of force per length: pounds per 3 inches (lbs/3”) and Newtons per 10cm (N/10cm). The chemical formulation of the netting determines the softness, brittleness,
strength and roughness of the final configuration. Our engineering team can collaborate with you until the right formula for your final application is identified.
Elastomeric netting is an ideal stretch engine material that offers flexibility, comfort, stretch, and recovery for your next project.
Elastomeric netting is made with specialty polymeric materials that provide stretchability in one or both directions of the web.
Our improved technology makes elastomeric netting a competitive alternative to other stretch engine materials such as films, spandex and stretchable nonwovens.
EASY TO LAYER
Depending on the final product application, manufacturers, converters, and laminators may produce composites with nonwovens and other fabrics.
BREATHABILITY & MOISTURE MANAGEMENT
Elastomeric netting offers superior air permeability, heat transfer and water vapor transmission performance to create comfortable composites.
Resins and Additives
Conwed manufactures a diverse portfolio of netting products using different resins and additives to meet specific product requirements.
From standard PP resins to HDPE, LLDPE, EVA, etc., Conwed has extensive experience developing special formulations for different product applications and performance targets.
VERSATILITY AND LIFESPAN
Each product development challenge requires different solutions and our team works extensively with customers to deliver the desired results. For example, in certain short-term erosion control applications, Conwed™ Netting is designed to degrade after a determined exposure to light, water and oxygen. In other instances, Conwed™ Netting is tailored to resist UV light to prevent undesired degradation before the useful life of the product
