3. INSTALLATION USING ROOF CLAMPS
SECT can be installed on roof clamps. Channel feet are supplied as an assembly with the roof
clamp. Use product codes:
SPCF305 (SECT Channel Foot 305), to suit a variety of standing seam roof sheet profiles,
such as Lysaght Longline 305
SPCF406 (SECT Channel Foot 406), to suit a variety of narrower roof sheet profiles, such as
Lysaght Klip-Lok 406
SPCF700 (SECT Channel Foot 700), to suit a variety of wider roof sheet profiles, such as
Lysaght Klip-Lok 700 High Strength
Roof clamps can be rotated 90 degrees by loosening the fastener that connects it to the
channel foot, then re-tightening.
Roof clamps should be installed directly on top of the purlin, i.e., on top of the concealed clip
which holds the roof sheet to the purlin. Channel should be extended past the last module
frame to overlap the next available purlin.
Roof clamps 406 and 700 are supplied with EPDM mats, which provides a level of separation
from the roof sheet, and corrosion protection for the roof sheet. According to the BlueScope
technical bulletin CTB-12 (Rev 3, November 2003) on dissimilar metals, aluminium accessories
are compatible with all common roofing materials, including galvanized iron, Zincalume and
Colorbond. Therefore, the aluminium channel foot is permitted to directly contact the roof
sheet. However, Schletter recommends the use of the EPDM mat where possible. Roof clamp
305 is not suited to the use of EPDM mats, because the oval point fastener needs to compress
directly against the roof sheet.
