Types of Climbing Plants
The design of your trellis system including all dimensions, cable diameters, types of fittings, distances from the wall and cable spacing, must consider the climbing behaviour of the plant species in addition to the aesthetics and desired project outcome:-
|a) Self Clinging Plants
• Require no auxiliary means of support.
• Can cause damage to the grout in masonry walls.
• Examples - Ivy, Fig, Virginia Creeper.
• Vines are climbing plants which wrap their stems around the support structure.
• They can sometimes put a great deal of load on to the mating structure.
• Examples - Wisteria, Honeysuckle, Chinese Star Jasmine.
c) Tendril Climbers
• Tendril Climbers develop special off shoots that grab hold of the supporting structure.
• They generally apply lesser loads onto the support structure; however, they may not be
suitable in high wind situations.
• Examples - Grape Vine, Passionfruit, Clematis.
d) Scrambling Plants
• Scrambling plants only use the trellis systems to prop themselves.
• Upward growth is supported by their prickles and thorns.
• Examples - Bougainvillea, Raspberry, Hardenbergia.
Ronstan AGS greening cable systems are suitable for use with vines, tendril climbers and scrambling
plants. Considerations for the selection of the specific species of climbing plant are varied and numerous. There is no short-cut for careful planning and consultation with a horticulturist is advised to ensure the correct selection is made.
As a general rule plants should be selected from species native to the local area – i.e. make a close inspection of the area surrounding the project site and select a species of climbing plant that flourishes in the immediate project vicinity. Other considerations include plant weight/loads, site conditions like exposure to wind, the proximity of other buildings, distance from wall, aspect, soil conditions and reticulation.
The differing growth characteristics of plant species will impose different loads onto the cables – direct plant loads and wind loads. These loads will be transferred through the system connections to the building face. The ability of the mating building structure to withstand these loads must be considered along with any relevant factors of safety or load requirements of the materials used in the mating structure itself. Safety implications, service life, fatigue (as may be caused by wind stresses or repetitive cyclical loading), type of load, exposure to ultraviolet light, corrosion and stress corrosion (such as in high humidity or chlorine environments) must be considered. A ‘safe working load’ is not specified as this is dependent on the factor of safety, which must be determined by the user relative to each application.
SYSTEM SELECTION AND GROWTH
Considerations for the selection of the specific species of climbing plant are varied and numerous. There is no short-cut for careful planning and consultation with a horticulturist is advised to ensure the correct match of system and species is made for satisfactory growth. Plant weight/loads, site conditions like exposure to wind, the proximity of other buildings, aspect, soil conditions and reticulation all need careful consideration.
PRODUCT INFORMATION AMENDMENTS
All catalogue information is subject to specification changes during a product’s life-cycle. Any alterations will be posted on the Website: www.ronstantensilearch.com which should be considered the most up to date source of product information.
No guarantee can be provided for product life, load capacity or any other factor due to the variability in usage. While every precaution is taken in the product design and manufacturing processes to minimize the effects of corrosion and stress corrosion, there are also preventative and corrective treatments that can be carried out after installation. Contact your local Ronstan representative for further assistance and advice.
In addition to your rights implied by law, the goods manufactured or sold are warranted to be free of defects in materials or workmanship for three (3) years from the date of purchase by the original purchaser except that:
• This warranty shall not apply to any product which has been improperly fitted, improperly maintained, or used in any application for which it was not intended.
• This warranty shall not apply to normal wear which can reasonably be expected in normal use of the product.
• No warranties are made that any products are fit for a particular purpose.
• The liability shall be limited to the repair or replacement, at the manufacturer’s discretion, of the defective goods.
• The useful life of any rigging product is determined by the above factors and must be assessed in each application, and thus no guarantee can be provided for product life, load capacity or any other factor due to the variability in usage.
