Panel Length - Standard length is 10' (3m)
- Maximum length is 20' (6m)
Panel lengths over 13’ (4m) must be allowed to expand and contract with temperature change with the use of slotted holes for fasteners or special sliding clips available from RHEINZINK.
It should noted that long panels can be difficult to handle and are more easily damaged during installation.
Splice plates between panels allows for the linear expansion that occurs due to temperature changes. This gives a seamless appearance.
Vertical joints, if desired, can be designed in a number of ways, e.g. by rear-installed channels, sheets or pilaster strip profiles.
Fastening - Concealed fastening with stainless steel fasteners
The reveal panel is fastened to galvanized hat channels or Z-girts with stainless steel fasteners of a size and frequency adequate to resist wind loads. The fasteners are screwed through the bottom flange of the profiled panel. The top flange of the subsequent panel slides up and into the return of the upper panel’s bottom flange. This, then, conceals the fastener heads of the upper panel and provides joint closure.
Fasteners
- Fasteners are designed to allow for movement of the panels.
- Self-tapping stainless steel screws are recommended
Self-tapping screws are particularly suitable for fixing the installation profile to the metal substructure. Installation is done in one operation, using an appropriate setting tool. No pre-drilling is required.
The screws are selected based on various criteria:
