Klip-Tite new generation concealed fix roof sheeting

Photographs of two projects of equal age showing the dirt (black and brown marks) that accumulates on the roof is trapped at the bottom of the narrow flutes, and the bottom of the sides of the longitudinal pan stiffening ribs with minimal accumulation at the transverse pan stiffeners.

Klip-Tite is a new generation concealed fix roof sheeting offering superior wind uplift capabilities to that of any other concealed fix sheeting in South Africa. Klip-Tite incorporates transverse stiffener ribs in the pan, which is the latest technology in the South African roofing industry. It’s manufactured in continuous lengths with on-site rolling for sheet lengths in excess of transportable limits.


  • GRS-Technical-Bulletin-Klip-tite-engineered-concealed-fix-system_image1Independent tests show characteristic resistance to unclipping of 3.4kPa, which, with a material factor of 1.3, gives a design ultimate uplift stress of 2.6kPa
  • Klip-Tite sheet and clip engineered as a unit to provide a high-performance roofing system
  • The most common reason for failure during wind storms is when the sheet disengages from the clip. It is thus of utmost importance that the holding down capacity of the roof sheet matches the holding down capacity of the clip.
  • Transverse stiffeners in pan of the sheet act as beams to limit deflection and keep the sheet engaged to the clip
  • Transverse stiffeners provides strength to sheet and accumulates less dirt than longitudinal stiffeners


  • Extended base of clip allows for a more accurate installation
  • Predetermined pilot holes at interlocking of adjacent clips ensure sheets are not stretched beyond 700mm cover width of sheet, resulting in proper sidelap interlock of adjacent sheets.
  • Clips are installed in a straight line when using spacer hole
  • Extended base eliminates insulation bulge when used on blanket type insulation providing higher wind uplift capability
  • Extra base stiffeners allow for improved stability on the purlin, LSF battens or on “Ash Grid” type spacer systems
  • Design of clip’s spur ensures that full length of spur is in contact with sheet during deflection
