STEEL-PANEL 850 wall cladding profile combines style, strength, durability and the wide colour choice of COLORBOND® steel.
It’s engineered from high tensile steel and rollformed locally in a distinctive profile to provide a high quality product at a cost-effective price for any wall cladding challenge.
The sheets of STEEL-PANEL 850 overlap each other and are fixed progressively along the building in the opposite direction to the prevailing weather. This gives complete weather protection and a fast and efficient method of installation. Each sheet consists of an “over” rib and an “under” rib which combine with neighbouring sheets to form an effective seal against water entry.
The faces of the supporting members must be true and all in the one plane for a professional finish.
STEEL-PANEL can be bent along the sheet at minimum bend radius of 3mm, however bending across the sheet is not recommended.
LAYING (RIBS VERTICAL)
Start at the end of the wall which is away from the prevailing weather. The over-edge should be as shown:
LAYING (RIBS HORIZONTAL)
The edge laps must face downwards with the over edge (double side rib) on top as shown. If end laps are necessary on long runs, allow 75mm per lap. End laps should be sealed with suitable sealant.
Steel Framing (up to 5mm thick): No 10x16 Wafer Head Self Drilling Tek Screws OR blind rivets.
Timber Framing: No 8x25 Pan Head Type 17 Self Drilling Wood Screw OR 25x02.8 Galv. Clouts.
SIDE LAP FASTENERS
Use No 8x12 Hex Head Type S Self Drilling Screw with Neo. Washer OR blind rivets.
When using the overlapping rib jointing method, these are added at the midspans of the sheets when support spacings are over 800mm. When using the overlapping edge method, side lap fasteners are required at maximum centres of 300mm.
LOCATION OF FASTENERS
At the ends of sheets and at end laps, fasteners must be located at every second valley. At intermediate supports a fastener is to be located either at the side lap or adjacent to it, with four fasteners used equidistant across the sheet. Note: In some applications the number of fasteners may be reduced by up to 50%.
Always use a spreader bar and fabric slings to prevent damage when unloading bundles of sheeting with a crane. Use clean dry gloves and do not drag sheets over each other when manually handling sheets. Storage of sheets should be above ground and under cover.
Do not locate fasteners less than 25mm from the end of sheets. Do not use punches to form holes for fasteners. Holes are to be drilled or self fasteners are to be used.
STEEL-PANEL 850 can be cut in the factory to any length specified by the customer. Tolerance on the length is +0mm-5mm.
MAXIMUM SUPPORT SPACINGS FOR NON-CYCLONIC CONDITIONS
The recommended maximum support spacings are 600mm for exterior applications, and 900mm for interior applications. These apply for buildings located under the following conditions as specified by AS.1170 Part 2 SAA Wind Code:
Area – Non Cyclonic
Max. Building Height – 10m
Wind Velocity – 50m/s
Internal Pressure Coefficient -+0.2
