The most distinctive feature of this product is its elastic steel clip teeth,located at the ends or along its length.These teeth are often heat-treated for potential good fatigue resistance,allowing them to deflect during installation and spring back to lock into place.The joist is generally lightweight,facilitating one-person handling and installation.Its flat top design provides a broad support surface for ceiling panels,while the clip mechanism remains concealed above the panels.
The web height is commonly low-profile(e.g.,16mm)to suit shallow plenum depths.The size,shape,and spacing of the clip teeth are precisely matched to the receiving slots on the target main joists.Material thickness typically ranges from 0.35mm to 0.45mm,balancing elasticity,strength,and cost.Standard lengths correspond to common building modules.Dimensional tolerances are critical for ensuring smooth snap-fit operation and a stable final grid.
Widely used in commercial and public spaces seeking a clean,unobstructed ceiling aesthetic,such as high-end offices,hotel lobbies,exhibition halls,museums,and hospitals.It is used with square or rectangular metal panels(often aluminum)to create a seamless,frameless ceiling surface.Once the system is installed,only the smooth ceiling panels are visible,with all grid components hidden behind.
