Which fasteners do I use for installing the roofing sheets?
Here at Metal Roofing Online, we only use and recommend Class 4 screws when installing your roof sheeting as they last considerably longer in the elements. In a standard roofing application, when fixing to either timber or metal purlins, we have in our range a Multifix screw which is the perfect choice for this roofing iron. These are able to colour matched to your sheets. 

Installing Trimdek for Walling Using the Pierce-Fixing Method

If you are planning to install COLORBOND Matt Trimdek as a wall cladding, it is highly recommended that you use the pierce-fixing method over the concealed-fixing method. With this method, you can affix the screws either through the crests or the pans or valleys. For wall cladding purposes, it is highly recommended that you affix the screws through the valleys for three key reasons. First, the screws are less obvious and the aesthetic lines won't be broken. Second, because the fastener goes through the cladding through the valley, the chances of the cladding getting deformed is practically eliminated. Finally, affixing the screws through the valley ensures a tight water seal. If you are going to affix the screw through the valleys, you will need a side lap fastener for all the laps and support. If you wish to minimise the time, money and effort required for this task, you may use a crest fastener. Prior to the installation of the wall cladding, make sure that the support structure is in the same plane. Before laying the sheets, check the supports and make the necessary adjustments. Remember, it will be doubly difficult to make adjustments once the sheets have been installed. Begin installing the COLORBOND matt Trimdek sheets in the area which you expect the prevailing weather to come from. Before lifting the sheets, it is best if you turn these first on the ground. It is much safer that way. Before affixing each COLORBOND Matt sheet, position it against the building and check whether it is aligned with the end wall as well as the parapet or transverse wall. After finishing the installation of the first sheet, make sure that the next sheet is aligned properly against the previously installed sheet and from the end of the sheet to either the fascia or purlin. You can either install each sheet quickly before moving to the next or you can simply fix one sheet after another and then use the intermediate fasteners when all the sheets have been laid into place. From time to time, double check each sheet to see whether each one is aligned with the first sheet that you installed. Once you are halfway done with the installation, check the sheets and their measurements from the end line so that the final sheet is parallel with the end of the roof. If you think you are off by a little, you can adjust by aligning and fixing the lap and then fixing the outer edge of the sheet by affixing the fastener either closer or further than your original plan. You can purchase and the other materials you will need for roofing and wall cladding here at Metal Roofing Online, your trusted Bluescope Steel supplier. Roofs are the most important part of when building a house.
