Ground Screw
Ground screw is made of material Q235 and finished by hot dipped galvanized. They are widely used in foundation system for solar panal, fence, wooden house, advertising boards, flag pole and etc. They can be easily installed by spiral piling machine, no digging, no concrete, no waitting, much convenient,cost effective, time saving and environmentally than concete foundation.
Ground screw technology is known worldwide and eliminates the need for concrete footings.
They are installed much like a traditional screw which allows them to be set within minutes--not hours or days like concrete. Ground screw foundations can be used to secure almost anything into the ground--from solar lighting, road signs, and recreation equipment. Plus, they are suitable for a wide range of soil and ground types, are stable and long-lasting.
Advantages:
1.No excavating, digging, or concrete
2.Installs within minutes
3.Instantly loadable with no waiting time
4.Stable, durable, storm proof, water proof, and secure against wind
5.Environmentally friendly, ecological, and sustainable
6.No damage to surrounding landscape
7.Fast and inexpensive to dismantle and relocate
8.Can be installed into sealed surfaces
Type:
1.Anchor with flange
The end of part is welded with flange which is easy for connections. This type is usually used for buildings and wharf because of its high accuracy and stability.
2.Anchor with U plate
The end of part is weld with U shape plate, this kind of anchor has good performance in connection and easy for operation. Normally used for fence and barrier.
3.Anchor with nuts
This type of anchor is fixed by three or four nuts which means easy for installation. It`s insert length can be adjusted according to customer demands. Normally used for the base of solar panels.
Benefits:
1.Flexible and efficient: the ground screw can be used as a foundation for a variety of permanent or portable ground mounted applications, from single highway signs, to fencing and large scale solar farms.
2.Unbeatable construction times, with top precision: the ground screw is installed using a number of different aids and machinery. It is driven into the ground at the exact point in a matter of minutes
3.Concrete-free innovation: no digging, excavation, wet trades, or curing time, which means no wait, and no delays!
4.Sustainable, cost-effective alternative to traditional foundations: The Honde ground screw is made from 75-80 per cent recycled steel. Ground screw installation is a low impact, vibration free process, as well as being completely and easily removable. Installation and removal have minimum impact on the landscape
5.Safe, robust, and uncomplicated: our ground screws have been stringently tested and gained European wide compliance through TUV Reinland and ISO1461 certification
6.Highways approved in the UK: our ground screw has been approved for use within highways, including passively safe supports and accepted by the Highways Agency for use on motorways and trunk roads. It has also been approved by the German Federal Road & Transport Authorities for the erection of all types of traffic and directional signs
6.Proven technology in renewable energy: the ground screw foundation has been used for over 10 years across Europe to install over 800MWp of solar PV programmes and supports over 10 per cent of the world market. In the UK, during 2011 and 2012, our ground screw was the chosen foundation for the construction of some of the UK`s largest solar farms, as well a large number of other schemes
7.Long-lasting, with consistent and reliable performance: our ground screw provides a guarantee of 20 years and have been successfully tested to 30 years` lifetime in the ground, with an overall life span of up to 50 years.
