The ATTAS® - Steelgatesystem is made of cold rolling steelprofiles that are specially developed for the requirements of cantilever sliding gates.
For the manufacturing of our profiles we use coils that are cut from finegrained-steel into the appropriate width. The coils are assembled so that they can be completely galvanized with zinc, this enables the longitudinal edges and corners to be protected from all sides. This is an important advantage when comparing our profiles with the ordinary process done partially by first cutting the zinc-plated material and then shaping the corners and edges. Our symmetrical zinc coating percision makes for an extremly light response when opening the gates, more so than when the whole gatebody after production would be dipped into a galvanized bath of zinc.
The utilization of finegrained-steel is particularly for coldformation suitable. Due to this special method which has proved its stability and its soundness, so that the tread where cracks and other material weakness could form (around edges) can be avoided thus not impairing the function of the gates.
In the more than 25 years of experience the form of our Profiles have been constantly improved so that our steelprofilesystem reaches the highest quality possible. So today we can broaden the roller surfaces, and the quality of steel has improved. In particular the guidance of the secluded bottom flank is highly stabile, which is torsion resitant, which provides an easy moving gate; also taken into to account for is extra weight from passengers this is accomodated without difficulty, thus not damaging or distorting the profile. It is precisely this special manner of how our profiles have been moulded, they are turned towards the inside which interlocks allowing larger gates to be built with a passage clearance width of 20 meters. It`s this method which allows a profile to be built without having to have an extremely thick gate wall. These advantages should be taken into consideration when comparing with competitors.
However, the thickness of the profile wall is chosen so that when required the gate can directly be built in without the use of a bottom railing support . Should you want to hear more on this method please inform us and we will send further information. ATTAS® generally recommends production of the gatebody including the bottom railing support then placing it on the profile afterwards. This recommendation is based on statistics.
The sliding roller components are made of a weldment, partially made from solid finegrained-steel, from ST52 and from stainless steel. The larger sliding rollers are Polyamide 6 (PA6) showing a high resistance to tears and breakage, PA6 keeps holds of little water, and responds only slighly to heat expansion. The high tenacity and impact strength of this material makes it perfect for the use in cantilever sliding gates.
The mounting of the slide or support rollers is done by using extremly large ball bearings and partially done by using large roller bearings, and are built so that they are dustproof.
Through the combination of these components, bound together with end bearings resulting in the extrem mobility of the whole system, which positivly effects the hands on operation and the convenient adaptation of size on our gates motor.
Interference that can come from the side such as strong winds, shearing forces, or through a delay when the gate is partially in the sun has been compensated by the stabile inner crossing rollers. In addition this function is backed up with wider rollers in which their interior and exterior flanks are also used to guide and assist. So it is possible, that by minimum air permeable gates the upper rails may not be needed. ATTAS® suggests production of the gates including the upper railing for extra durability as a safety precaution, thus avoiding potential gale winds and other weather factors.
Steel profiles are for many metal construction firms the best solution, because sufficient knowledge is available. You may choose from different forms of profiles, rods, bars, and by special order, measured and cut to your needs. Steel profiles can be processed without difficulty and extra precautions are not necessary as long as you follow a few productional instructions. ATTAS® steel profiles for cantilever sliding gates in comparison to other products provides an optimal price-performance ratio.
All of the above mentioned aspects are important when comparing to other profile forms and profile models. Of course ATTAS® delivers aluminum profiles, although we then do advise that the complete gatebody be built of aluminium.
