PVC is stronger, lighter, more durable and requires less maintenance than wood, and our posts are expected to last at least 50 years before replacement. We think this is a monumental improvement over wood since 10 percent of all wood posts must be replaced annually. In addition, clips are already formed on the post, saving countless hours of make-ready work.

We believe this comparison takes place in Australia and only present it here
to illustrate the potential long-term cost savings of using PVC

  Treated pine (CCA) Steel Polymer
Weight (kilograms) 25 3.6 3.7
Quantity per 35-tonne truckload 1400 9722 9459
Time to erect (minutes) 04:50 02:00 02:00
Cost to erect at $17/hour $1.28 $0.57 $0.57
Transport cost (each/1000km) $1.79 $0.26 $0.26
Price per post $5.00 $7.25 $14.50
Galvanized staples (@ $.04 each) $0.24 $0 $0
Measure and fix staples to post $0.28 $0 $0
Drill post for wire $2.00 $0 $0
Cost per installed post $10.50 $8.07 $15.33

Cost per hectare @ 500 posts/ha $5,292 $4,037 $7,665

Annual recurring cost per hectare to replace failed posts (splits, corrosion, rot, accidental etc.).  Cost based on field replacement of $150 per pine post. 10%
$7,500

$1,500

Cost per hectare after 10 years $80,292 $64,037 $22,665

Net cost per post per year $16,06 $12.81 $4.53

CCA posts measure 100 to 125mm diameter, all posts 2.4 meters long 6 staples per post, no allowance for wire or end posts.  The 20% replacement cost for steel is due to short life of some of these posts types in many soil types as estimated by the people who collected the date for this table.

This information is based on observations of vineyard workers installing posts in the Mildura region.
