The GTS ground mounting system is a cost performance streamlined structure, the supporting frame is delivered with highest pre-assembly to unfold at site. The optimized design is done by experienced structure engineer, this is essential as high loads caused by wind and snow.

GTS ground mounting system on screw pile utilize ground screw/helical pier for solid foundation, and its variable inclination and height makes plant design flexible. Made of aluminum and hot-dip galvanized steel, the GTS ground mount on screw pile is extremely low-maintenance during its entire life time. Fully recyclable, aesthetically pleasing, ideal for quick installation.

Ground screw, also known as helical piers, anchors, piles or screwpiles, are deep foundation solutions. Due to their design and ease to install, they are most commonly used whenever soil conditions prevent standard foundation solutions. Instead of requiring large excavation work, they thread into the ground. This minimizes installation time, requires little soil disturbance, and most importantly transfers the weight of the structure to load bearing soil.

Benefits

  1. Screw piles thread in with 0 excavation — frames arrive at highest pre-assembly and unfold at site.
  2. Elevation to 60°, rated to 80 m/s wind and 100 cm snow (AS/NZS 1170.2:2011, JIS C 8955:2017).
  3. On soft or undocumented soil, on-site pull-out tests size the piles — 12-year warranty on the structure.

Frequently asked questions

What if the soil is soft or unknown?

On-site pull-out tests size the piles, so foundation rework never happens.

How do you size the structure for wind?

Site wind speed drives member sizing to AS/NZS 1170.2 / ASCE 7-22, and every design ships stamped - no under-engineered arrays.

What about snow load?

Your region snow zone enters the same stamped calculation, so spring collapse claims never start.

How does it handle corrosive environments?

The ISO 9223 class (C1-C5) picks the coating - HDG, ZAM or 6005-T5 aluminium - so rust never becomes a warranty fight.
