Flush Ground Hatch in Aluminium or Stainless Steel

Custom Solution for Technical and Urban Environments

SAC is a product line of flush, custom-made ground hatches manufactured from aluminium or stainless steel. These hatches are designed to provide safe, durable, and visually appealing access to technical spaces, utility installations, or service corridors in both public and industrial settings.

SAC hatches are flush hatches, meaning they have a smooth, even surface with no recess — unlike recessed hatches such as HIAC, which can be filled with materials like stone or wood.
