“Riblines” and Netting Panels

Friday, April 9th, 2010

Taking a look through many of the custom netting panels and barrier nets that are facilitated by Gourock, you’ll notice the use of “riblines” running through many of them.  The term “ribline” refers to the installation of an additional support rope that is sewn-in to the interior area of the netting panel.  This technique is great for specialty nets that require additional netting connections (to cables, framing, or existing structure) due to their overall sizing or weight.  Sometimes, they are installed through the netting panels in order to create a ‘corner’ attachment point for a netting panel that will be running up a vertical wall, and then over a ceiling area.  Whatever the situation may be, the use of riblines is quite common and in many times very recommended for long-term durability of the netting product.

As is quite common for most any large netting panel production, the perimeter edges of the mesh itself will typically have a rope border installed (sewn-in) to finish-off the product, and to provide strong attachment points for the installation.  5/16″ Dacron® rope (3200 lb./test) is the most commonly supplied rope bordering material provided on Gourock.com supplied nets.  This is also the same rope that riblines are created from, so you can be assured that all connection points during the netting panel installation have the same visual appearance as well as strength characteristics.

In the 4 images below, you can view 4 netting productions that feature riblines in their design.  Each of these nets was facilitated by Gourock and shipped out to the customers within the last 8 weeks.

The following 2 diagrams display barrier netting panels that have both vertically and horizontally installed riblines in them.  The most particular reason for the use of the riblines on these productions is their sheer physical size and weight.  Both nets are over 4,000 square feet in area, and were being installed in permanent outdoor applications.  In order to have a dependable amount of resistance against wind, and to line-up with the contractor’s cables/poles, the combination of the vertical and horizontal riblines was a perfect solution for dependability.  These were both commercial installations at public venues.

The following diagram shows a series of netting panels that were constructed as ceiling nets over the top of an existing fencing structure.  These nets have a few unique features in them, including square mesh construction (which is great for horizontally installed netting panels), “Diamond-Shield” antifoulant dipping, and riblines running in both directions.  For this particular installation, the use of the Dacron® rope riblines was to provide attachment points for divider nets and impact panels.

The fourth diagram that is shown below, demonstrates a barrier netting panel that was being installed at a private residence, in order to protect the property from balls from the nearby golf course fairway.  In this instance, the vertical rope riblines were installed at specific intervals to line-up with the installation poles that the netting was being installed between.  The top edge of the panel, as well as both sides are all Dacron® rope-bordered as well.  However, the bottom side was provided without a border installed, as the customer had a unevenly sloping property grade – and preferred to trim-off the excess mesh to match the slope once the netting was installed within the poles.
