Purlin Hex Roof

In timber construction purlins are nailed to the rafter or supporting trusses while in steel roof construction they are welded or bolted to the rafters or trusses by the means of cleats.

Purlin hex roof. The wider the roofing panels the greater spacing distance you should put. The purlin is adjusted into line and the 12mm diameter hex flange bolts on the brace tightened. The jm purlin fastener is a steel coated fastener with a hex head and 19 mm drill point. Purlins traditionally support the roof deck cladding sheeting and are in turn supported by the principal rafters steel beams etc.

As structural members they resist loads. Insert two equally spaced nails into the rafter. Purlins are non pressure treated 1 x 4 x 12 lumber that is installed on to the roof in a specific layout pattern and screw pattern. A common arrangement is a rafter and purlin system which combines purlins and rafters.

20 mm drill point allows the fastener to be drilled through the purlin before the threads engage into the standing seam metal roof. The width of metal panels will determine the rafter spacing. E purlin offers the greatest flexibility in the design of stick roofs clad with tile or metal sheeting. Do all roofing projects require purlins.

The drill point allows the fastener to be drilled through the purlin before the threads engage into the standing seam metal roof. 2 8 mm in seconds. Lay the first purlin at the ridge of the roof down to the chalk line beginning at either corner. The adjustable brace offers up to 20mm of adjustment.

There is a chance of damaging roofing sheets if you are failed to do so. The omg purlin fastener drills through steel up to 12 ga. The metal roof purlins spacing must be done correctly within narrow tolerances. Snap a chalk line horizontally across the roof two feet down from the top.

Fasten the purlin with 16d common nails into each vertical rafter. In the past the majority of roof structures were of wooden construction but over the past 15 to 20 years there has been a vast shift away from wood to metal mainly steel roof construction. E purlins are design engineered to maximise the efficient use of material and time. Low profile hex head has a smooth surface to ensure that there is no damage to the membrane.

The purpose of the purlins is to provide a solid foundation for the metal roofing panels and trim to be screwed to. They are available in a range of lengths from 3m to 12m with longer lengths available by special manufacture.
