The China based HS Metal Products company started manufacturing and supplying ground screws since the year 2007. In this respect, they have acquired a total of 5 patents across 2 different categories- 2 certificates of Utility Model Patent and 3 certificates of Design Patent. Ground screws are made of steel and bear an outer hot dip galvanized protective coating. They are also referred to as “helical pile” or “screw pile”. They are used in the construction of fences, guardrails, advertising boards, houses, solar power plants etc. Based on utility, there are 5 types of ground screws viz. ground screw, ground screw with flange, ground screw with stirrup, ground pile and ground pile with flange. Also, they can be custom made according to drawings or samples received from the client. In any case, ground screws from HS Metal Products come with a guarantee of world-class quality and that too, at a very competitive rate, as per industry standards.
Ground screws are unique products that offer remarkable advantages over other traditional products with similar usage in construction e.g. conventional piles & posts or pad and post systems. Since their discovery, they have come a long way and are now available in a wider array of shapes and sizes. Their height and width are made to vary as per fixing place. HS Metal Products offer an additional service towards determining the most suitable type of ground screw for a particular project i.e. soil investigation report generation. It is advisable that consumers consult the knowledgeable suppliers of the company before determining the best type of screw to be used for each specific application, at a particular location. This will help to eliminate the risks associated with employing a ground screw variant that is inadequate for the task.
Ground screws have become the most popular choice in construction within a very short span of time after their invention. They make work very easy especially for the home handyman involved in Do-It-Yourself (DIY) projects. Position of simple ground screws can be easily modified- removed and repositioned, without any form of digging or use of concrete. This allows significant reduction in time and manual labour. Ground screws can be fixed in a manner similar to wood and metal screws. Their spiral built facilitate easy insertion into the soil with application of much less force. Also, their face provides increased surface area which allows much more stable contact with the binding soil. This results in decreased possibility of shifting and frost heave due to dry or wet soil conditions. It is needless to say that the use of ground screws impart high degree of stability and durability to the structures in which they are used as a component. However, ground screws are not suitable for some soil types, such as those with lots of gravels, sand, shale, stone, frozen soils etc.
In spite of these drawbacks, ground screws are pretty adaptable and can be inserted in close proximity to overhangs, where piles cannot be driven. They can be easily installed on slopes with the help of light-weight equipments used for many other applications and in a less disruptive manner i.e. the surroundings can be left untouched. This also means less noise during construction and less waste left over and less clean-up after completion of project. Ground screws can be subjected to structural load immediately after installation and does not need any window for incubation. Undoubtedly, the use of screws is a very convenient and cost effective affair.
