Low Profile Wall Cladding
Versatile and attractive, fluted, low profile walling
Stratco Maxirib ideal for applications such as ceilings, walling, screens, garage doors, fascias and barge boards. As an attractive cladding with a fluted profile, it can be readily used both internally and externally with the exception of roofing. Maxirib is ideally used on flat surfaces but can be spring curved according to Stratco recommendations.
Maxirib is available in a full spectrum of colours or un-painted zinc/al. The slightly fluted cladding design ensures strength along the length of the sheet, yet flexibility across the width.

- Its profile design allows for neat, easy packaging.
- Maxirib can be fixed with the flutes running horizontally or vertically.
Maintenance Requirements
The performance of Maxirib over time depends on its correct application and maintenance. Maintenance should be performed as often as is required to remove any dirt, salt and pollutants. Where used in severely corrosive environments, cleaning should be performed more often. It is important that screws have the same life expectancy as the cladding you have specified.
Packs of Maxirib should always be kept dry and stored above ground level while on site. If the sheets have become wet, they should be separated, wiped and placed in the open to dry.
Refer to the 'Stratco Selection Use and Maintenance' brochure, for more detailed information about the correct use and maintenance of this product.

Fixing Information
- For overlapping or edge lap applications, use side lap fasteners at every 200mm to 300mm centres.
- When using end laps, allow at least 75mm per lap.
- Fasteners should be placed at the side or adjacent to it.
- To ensure a quality finish, fasteners at the ends of Maxirib sheets should be placed in every second valley.
- For intermediate support applications, it is recommended that four fasteners be used at equal spacings across the sheet.
- For fastening the Stratco Maxirib to steel supports of up to 5mm thick, use 8 x 12mm wafer head self drilling and tapping screw or 4.8mm aluminium blind rivet.
- For fastening to timber, use 2.8mm x 25mm clout, or 8 x 25mm pan head self tapping wood screw.

Fixing Recommendations
Note: The following recommendations apply to non-cyclonic areas.
- All fasteners must have neoprene washers to prevent water penetration.
- Side lap fixing is recommended at no greater than 300mm centres for external applications. For internal applications where support spacings exceed 1000mm it is recommended side laps are fastened mid-span. Use either 8x12 mm self drill stitching screws (with seal) or 3.2 mm sealed blind rivets.
- The below fastener sizes are suitable for fixing over an insulation blanket up to 55mm thick. For thicknesses up to 100mm, the next standard screw length to that indicated is to be used.
