SALTUS™ Composite poles for the Agricultural Industry
DESIGN STORY
Note:
A wooden pole with OD=50mm will load test up to 5 tons depending on moisture content and sun degrada<on. In engineering prac<ce wood will be downrated with 50% due to variability to 2.5 tons
The pole is overdesigned in vertical load, but design limited for AFFORDABILITY to be just STRONG enough for hurricane winds from the side when fully loaded
SALTUS™ Composite Vineyard Support Poles
UNPARALLELED total OWNERSHIP COST
Consequential losses due to failure of timber poles over the expected life cycle of the Saltus pole are not shown, but makes the cost of the pole insignificant
SALTUS™ Composite Support Pole for Vineyards
Deflection at top of pole as calculated for a wind load force of 112 km/h (365 Pa). As can be seen from the table, all designs are within the specification of 15% deflection of total length above ground when carrying full grape load.
MIDDLE LAYER: FIBREGLASS WITH RESIN
Fibreglass acts as main load bearing material with its excellent compressive and tensile strength properties.
Fibreglass to resin
ratio is 70:30.
INNER LAYER: PLASTIC TUBING
Plastic tubing is used for increasing wall thickness and also adds elasticity to protect the fibreglass shell. Plastic tubing is typically used as water irrigation pipe and has very little load bearing compressive strength.
Attachments to SALTUS™ Composite Vineyard Support Poles
Standard hook recommended for vineyard support cables – cable can clip in from top or below
ALL types of hooks can screw into the SALTUS™ Poles

INSTALLATION
In well prepared and/or sandy soils Saltus posts can be planted by hand without the need for hammering the pole into the ground. Planing easily by hand has a 20% saving on labour costs compared to wood and other alternatives.
BENEFITS
Low weight & labour saving installation as well as long term cost savings.
32mm diameter design of 2.1m total length
(1.5m above ground)
Ballerina or Smart-Dyson
Designed for high yields per hectare
INSTALLATION
In well-prepared damp soils, planning posts is quick & easy. This results in much faster installation compared to other alternatives.
In tougher soils holes can be drilled or stamped for planning. Save 10%-20% on installation costs compared to heavier wood & other alternatives
BENEFITS
Low weight & labour installation savings. A competitive alternative with long term benefits.
43mm diameter design on 1.8m, 2.1m and 2.4m total length (1.2m, 1.5m or 1.8m above ground)
Geneva Double Curtain
Designed for high yields per hectare
66mm diameter vertical support posts with either 66mm diameter Y-arms or 43mm diameter Y-arms depending on row lengths, planDng width and yield.
If the ends of two neighboring rows are connected, 43mm diameter will provide ample strength and support
Extendable
Vertical posts can be ordered in 2.4m and 3.6m lengths (for supporting net or plastic film). Alternatively 2.4m lengths can be planted and later extended to 3.6m with a spigot joint.
MODULAR BENEFITS
Low weight, quick installation and labour saving. Posts are pre-assembled in our factory with collapsible Y-arms giving transport and quick re-assemble benefits.
Gable Trellis (Double Slanting Trellis)
Designed for high yields per hectare
66mm diameter vertical support posts with either 66mm diameter Y-arms or 43mm diameter Y-arms depending on row lengths, planting width and yield. If the ends of two neighboring rows are connected, 43mm diameter will provide ample strength and support.
Extendable
Vertical posts can be ordered in 2.4m and 3.6m lengths (for supporting net or plastic film).
Alternatively 2.4m lengths can be planted and later extended to 3.6m with a spigot joint.BENEFIT
Single light weight support posts can easily be installed on existing infrastructures as net or plasic film supports.
