The Fence Post

Protecting people from lava flows and from themselves.

There are some fencing products on their way to Hawaii. It seems some physical barriers are required to offset the lava-play aficionados and looky-loos that are putting themselves at peril. For us at home, observing the mesmerizing lava flows from your screen of choice is a popular pastime, quite understandably. However, far from these screens is the tough job of predicting the actions of people who are curious or foolhardy enough to want to get close to the volcanic activity. Louis Page has been called in to assist with the fence and mesh needed to curb these adventurous and possibly harebrained scofflaws. Remember that vinyl coated high tensile wire is the fence of choice for longevity and strength.  

Over-reacting? Nope. 

The dangers are numerous:

• Those fascinating sea water explosions of boiling water and steam require onlookers to be at least a 1/4 of a mile away for safety. That steam is not just water vapor! 
• Methane gas is created when vegetation is inundated without oxygen, exploding up to 100 yards ahead of the lava flow.
• The flows emit fumes that contain glass particles, sulfuric acid, and hydrochloric acid--no walking or standing in these toxic clouds.
• And some folks are enticed onto the new land created by the lava hitting the ocean--called benches--which are very unstable and prone to collapse.

Tourists and Hawaiian residents, observing bursts of gas and flame from the streams of lava, are being arrested for walking on hardened igneous rock and trespassing citations are handed out as people avoid barricades to take pictures, being caught going through areas with toxic gases.

The Phenomenon of Pele's Hair

And if the above list wasn't enough, there are the fine flaxen tresses of Pele. Named for the Hawaiian goddess of volcanoes, droplets of cooling lava are stretched up to six feet in the wind and should not be touched as it is actually volcanic fiberglass that can be very sharp and penetrate the skin. Here is a quick video to illustrate this phenomenon:

Fines

Entering certain zones bring a $5000 penalty and a year in jail. These reflect fines and punishments increased recently by the Department of Land and Natural Resources.  

Is there a type of fence that you need to manage or direct pedestrians? Louis Page can assist you in finding just the right fence for your situation.

First, a little background...

Merriam-Webster's Online Dictionary defines wire gauge as any of various systems consisting of a series of standard sizes used in describing the diameter of wire. It all starts with heavy coils of large diameter wire called rod made in a rolling mill. The rod is then shipped to a wire manufacturing mill. To make the wire used in wire fence and mesh, single strands are "drawn" through a series of increasingly smaller dies or plates and reduced to a specific gauge/diameter. The gauge is determined by the wire's final use - single strand wire, welded wire mesh or woven wire fence. Heating of the wire is not required in the drawing process.

In this article, we'll answer the following questions:

• What is wire gauge?

• What does it mean?

• How is it used to describe wire?

Wire Gauges Over Time

There have been several different gauge designations since the process outlined in the introduction was innovated.

Numbers have been used to designate wire diameter since 1735. They originally referred to the number of draws used in the process. The first draw was called 1 gauge, the second 2 gauge, the third 3 gauge, on down to the final draw of the thinnest wire being made.

The amount of "draws" required in the process determines why thick wires have a lower gauge number compared to thin wires. 9 gauge wire is thicker than 14 gauge because it requires fewer "draws" than 14 gauge.

The Birmingham Wire Gauge, also known as the Stubs Iron Wire Gauge, was originally developed in early 19th-century England as a means of standardizing gauge sizes. It has been used in a medical setting (needles) since the early 20th century. In 1855, Brown and Sharpe established a formula-based progression of 39 steps - from 1 gauge through 40 gauge. This is now known as the American Wire Gauge and is used extensively in the United States.     

Common Wire Gauges 

The following values show in inches the most common gauges of wires used in welded and woven wire mesh and fence:

• 8.5 gauge - 0.155 inch

• 9 gauge - 0.1483 inch

• 10.5 gauge - 0.128 inch

• 11 gauge - 0.1205 inch

• 12.5 gauge - 0.099 inch

• 14 gauge - 0.080 inch

• 16 gauge - 0.0625 inch

• 18 gauge - 0.0475 inch

• 20 gauge - 0.0348 inch

• 21 gauge - 0.0317 inch

• 23 gauge - 0.0258 inch

• 27 gauge - 0.0173 inch

There are many different combinations of wire gauge and mesh size manufactured. You can select the right product for the requirements of your project.
