TRACDEK® Klippon® is a concealed fixed snap-on seam roof/wall covering system that consists of structurally strong high-ribbed panels with wide-fluted pans for efficient water shedding and are fixed by means of concealed clips. All the ribs are clipped on and are interlocked. No penetration is done for its fixation to the roof or wall framing. These are ideally suited for regions which receive heavy rainfall and can be used on slopes as low as 1 in 20.
The clip-on side lap makes the Klippon® profile completely water-tight. The side lap is totally weatherproof. Any moisture drawn in by capillary action is trapped and dispersed by normal run-off.
Long lengths and weatherproof side lap allow the Klippon® profile to be used safely on roof pitches as low as 2 degree (approximately 1 in 30) for single length sheets, 3 degree (approximately 1 in 20) with end laps.

TRACDEK® Klippon® steel cladding is designed to be fastened to roof purlins or wall girts with fixing clips which are concealed during fixing and do not require any fastening holes through the steel sheets.
The clip for fastening Klippon® steel cladding requires only two fasteners per clip and provides an easy, positive engagement in the ribs of the profile.
The two fasteners are inserted only through the two punched holes.
Four dimples are also provided in the clip but these are for auxiliary fasteners only.
The clip has a short return leg and a long return leg. The clip must be positioned with the short leg engaging over the male rib of the under lapping sheet.
Because of the concealed clip fixing method, no fastening screws are visible and there is no screw penetration through the external sheeting.
Concealed fixing also offers an advantage of security. Entry into the premises by unscrewing of roof and wall cladding sheets is not possible. TRACDEK® Klippon® can be used for roofing large span factories, warehouses, commercial, educational, institutional, domestic and recreational buildings.

On most jobs, single long length sheets can be ordered to reach from ridge to gutter, so that the end laps do not normally occur. This is possible because Klippon® roofing and walling profiles are manufactured by a continuous process.
However, should it be necessary to use two or more shorter sheets to provide full length coverage, the locking ribs of Klippon® steel cladding are sufficiently flexible to enable it to be end lapped.
The illustration here depicts the correct method of placing the various profiles. The recommended minimum length of the end lap is 150 mm. The end lap should be weather-proofed by sealing it with non hardening silicon sealant. It can be further secured by using self tapping screws to the ribs.
TRACDEK® Klippon® can be used for roofing large span factories, warehouses, commercial, educational, institutional, domestic and recreational buildings.
