MARKING OUT CARPORT POSITION
A) IN GROUND FOOTING
Note: These column locations are very critical, as the roof sheet lengths are governed by these dimensions.
Place stakes at the carport column locations using the appropriate dimensions from the drawings supplied.
Therefore ensure the end frame spacing and the width of the carport are exactly as specified in the drawings.
Tie string lines between the stakes to ensure the footings are in line. Check the dimensions and diagonals for squareness.
The end frame spacing, gives the centreline spacing between the rectangular end portal frame and the internal gable portal frame. Where more than two internal portal frames are required, space at the dimensions specified on the drawings supplied.
Dig holes to the required size as stipulated by your Council Application Form. Place bricks in the bottom of the holes to give a solid base onto which the footing knuckles can be positioned.
If bolting columns onto existing concrete slab check to ensure concrete dimensions are as specified by your Council. Stratco does not take any responsibility for concrete failure.
Mark the position of the columns as shown in Figure 4. using the appropriate dimensions from the drawings supplied.
Therefore ensure the end frame spacing and the width of the carport are exactly as specified in the drawings supplied.

The end frame spacing, gives the centreline spacing between the rectangular end portal frame and the internal gable portal frame. Where more than two internal portal frames are required, space at the frame spacing dimensions specified on thedrawings supplied.
Place the footing plate in the appropriate locations as specified on the drawings supplied. The orientation of the base plate is such thatthe smaller dimension runs alongthe width as shownin Figure 4.
Mark the position of the holes through the existing holes in the footing plate. Remove the footing plate and drill into concrete using the values given in Table 1.
Use chemical anchors (for size refer to Table 1) together with the appropriate anchor capsules and install according to the manufacturers recommendations.
Leave the Stud Bolt undisturbed for the minimum time specified by the manufacturer for the resin to cure. Curing times are dependent on the concrete temperature at the time of installation.
Footing plates are not fixed until portal frames have
been assembled.
NOTE: Do not drill completely through slab, as chemical anchors require a solid base to bear against.
Note:
ASSEMBLE PORTAL FRAMES
Place the three knuckle connections inside portal frame members, using a hammer to tap in position (a block of timber should be used whenever hammering to avoid damaging paintwork).
Knuckles are colour coded as follows,
ensure that the correct knuckle is used for each connection.

A) IN GROUND FOOTING
Stand the end portal frame in the appropriate footing location and temporarily brace in position with clamps and struts (see Figure11).
Bolt the eaves purlins to the sides of the end frame columns using the 1.0 x 3/8 hex bolts provided, so that the purlins are level with the top of the column as shown inFigure 12.
Raise the other end frame and secure to eaves purlins. Ensure the ends of the purlins are flush with the outside faces of the end frames and the diagonal distances between the end frames are equal.
Check column base is at the ground surface, and the clear opening between columns is correct. Finally and most importantly check thatthe columns are vertical.
The concrete should be finished slightly raised towards the column, ensuring water runs away from the column, see Figure 11.
If concrete or soil is in permanent contact with the colorbond columns, corrosion will result in the base of the coloured column. Refer to the "Selection, Use and Maintenance of Stratco Steel Products" brochure for complete details ofmaintenance requirements.
Select the end rectangular portal frames. Place the footing plates in position and bolt securely.
Concrete the footings and leave overnight tocure.

Note: All purlins are supplied to suit the individual Heritage
designs, It is important you refer to your plan and check purlin lengths before cutting.
For extra long carports where you need to join two purlins, make sure they are joined over a portal frame and that the top lap faces the same way for both purlins to achieve a neat joint.
Cut the eaves purlins to correct length. Pre-drill the eaves purlins with 10 mm diameter holes at the end portal frame locations. Only drill holes through the single side rib of the eaves purlin (see Figure 10).

Screw the four seated hip rafter connections to the top inside corners of the structure, level with the top of the eaves purlin. Fix with two 10 x 16 hex head self drilling screws, see Figure 14.
Lift hip rafter onto seated connection ensuring double thickness flange is at the top. The hip rafter angles away from the rectangular end frame at 45° and is screwed onto the internal gable frame as shown in figure 14.
Cut hip rafters to length and pre-drill with one large 14 x 95 hex head self drilling screw at the end, ensuring double thickness flange is at the top. Position hip rafter on the seated hip connection and fasten underside with two coloured 10 x 16 hex head self drilling screws.
Screw the remaining end onto the top of the internal portal frame. Do not over tighten, preventing crushing of the hip rafter.
Note:This 45° angle is critical in ensuring correct shape of the Dutch Gable and therefore the sheet lengths.

Fasten the remaining roof purlins at the ridge location and 900 mm further down the rafter on each side. Position a purlin (first roof purlin - see Figure 15) 900 mm up the rafter from the eaves purlin (double flange on top).
Measure and cut a 45° mitre at the ends to fit flush against the hip rafter. Pre-drill with 14 x 95 self drilling screw at the internal rafter locationsand fasten in place.
Fix hip rafter connection plate to the underside of the hip rafter/side purlin joint using 10 x 16 hex head self drilling screws in the holes provided. Where end purlin supports are not required, locate front purlin on exposed connection plate, measure and cut a 45° mitre to fit flush with hip rafter. Screw in place (see Figures 14 and 15).

The collar tie spans horizontally across the outside of the internal gable portal frames. It aligns with the top of the hip rafters, so that the front roof sheets can run continuously over the rectangularend rafter, front purlin and the collartie.
Again pre-drill first through the double flange material with one large 14 x 95 hex head self drilling screw at each end, and fasten to side of gable rafters.
End purlin supports (68mm purlins) are only required if indicated in the drawings supplied. End purlin supports span between the collar tie and the end frame and are to be fastened in place using the 68mm purlin bracket before front purlin/s are screwed in place.
If only one end purlin support is required fasten one purlin bracket mid-span of collar tie and a second mid­span of the end frame (inline with the top of 120 end rafter) using two 10 x 16 hex head self drilling screws per bracket (Figure 16). If two end purlin supports are required fasten brackets at third points along both collar tie and end rafter (ie, 2 along collar tie and 2 along end rafter, Figure 17).
Measure, cut and mitre end purlin supports to fit flush between collar tie and end frame ensuring double flange is on top. When two end purlin supports are required legs on purlin brackets may need to be bent inward or outward slightly to accommodate angle between end purlin supports and frame.
Fasten end purlin supports in place using two 10 x 16 hex head self drilling screws per bracket per side of end purlin support. Cut (and mitre if necessary) front purlin/s to span between end purlin supports. 68mm purlin brackets are to be fastened to end purlin supports where they meet front purlin/s and front purlin/s are screwed in place.
This procedure applies to both ends of the Dutch
Gable unit.
Note :
CONCRETE REMAINING FOOTINGS (IN CONCRETE FOOTING)
GUTTER ASSEMBLY
Once the carport frame is complete concrete the remaining footings. Only concrete the galvanised tube footing stumps.
The concrete should be finished slightly raised towards the column, ensuring water runs away from the column, see figure 11.
If concrete or soil is in permanent contact with the colorbond columns, corrosion will result in the base of the colored column. Refer to the "Selection, Use and Maintenance of Stratco Steel Products" brochure for complete details ofmaintenance requirements.
(a) Measure and cut gutters to the appropriate length ( ie back length of gutter should equal outside frame dimensions + 30mm). Rivet and silicone seal.
(b) Notch hole in gutter and insert downpipe pop so that downpipe is in line with a portalcolumn.
If your column footings are in ground you would have installed your portal frames with a slight fall towards downpipe end. Ensure that the gutter is notched at the right end.
However if you are bolting the footings on to existing concrete slab, and there is a slight fall in the slab ensure that the downpipe is at the lower end of the slab to help the water run off). Fasten the pop in place using rivets and silicone seal.
(c) Cut 70 mm long metal strips from band supplied. Pop rivet these tags to the top of the eaves purlins and end frame rafters at 1200 mm centres. Rivet the back lip of the gutter to these tags, ensuring the back face of the gutter is held vertical as shown in Figure 18. Rivet and silicone seal.

b) Cut triangular gable infill panels (from the rectangular panel provided ), to fit the vertical gable frames located at each end of the Dutch gable roof. Paint the panels to the desired colour before installing. Rest the panels on the weather strip flashing. Fasten panels onto adjoining rafters through the top groove using 12x 35 roofing screws spaced at 1000 mm centres.
c) Hip Capping: Attach the small lengths hip capping to cover hip rafter seams, and mitre to fit the gutter corner.
d) Front and Rear Barges: The front and rear barge caps are fixed to the crest of the CGI roof and front of the gable infill panel. Mitre flashing to overlap weather strip and hip cap so as to give a neat water tight finish at the Dutch gable junction. Silicone joint if necessary.
e) If ordered, fix decorative strips todutch gable infill panel.
f) Gable Spires (Finials): If decorative gable spires are desired, nail the spire bracket to the back of the wooden spire, and rivet in position at the top of the ridge.
g) Ridge Cap: The ridge flashing can now be attached. The ridge should finish flush with the end of the carport, overlapping the front and rear barge capping to provide a weather proof seal.

ROOF SHEETING
Begin sheeting the internal framework of the carport roof with the large CGI sheets, allowing for a 40 mm overhang at the eaves into the gutter (see Figure 19). Always have the lap joint facing away from the prevailing wind direction on all carport roof faces. Lap final sheet to fit last span. Position, mark and cut triangular sheets for sides of Dutch gable roof section.
triangle offcuts are re-used on the opposite side of roof, so make sure the cuts are clean and accurate. Make sure offcuts are positioned correctly before laying the longer sheets, sothat capping direction can be determined.
Crest fix CGI sheeting with 12 x 35 Roofing Screws using 5 per sheet for end spans and 3 per sheet for internal spans. Work from one side of the structure to the other, marking and cutting triangular sheets as appropriate. Pan fix the triangular sheets to the hip rafter with 10 x 16 hex head self drilling screws.
Sheet the front and rear faces of the Dutch gable roof. Crest fix the sheets and triangular offcuts at the end rafter and front purlin locations. Pan fix with 10 x 16 hex head self drilling screws at collar tie and hip rafter locations.
Attach the gutter straps at 1200 mm centres by crest-fixing to roof sheets with 10 x 16 Screws. Construct two 85 mm downpipe offsets from the downpipe lengths supplied and attach to pops with rivets. Fasten the downpipes and straps to the adjoining column.

HELPFUL TIPS
MAINTENANCE
Leave plastic coating on members until they are about to be fastened to the structure. This will help prevent scratching of the colorbond finish.
Sweep the roof and clean gutters after the completion of work. Ensure any swarf andrivet stubs are removed as they can cause unsightly rust stains.
Leave bracing struts in position until structure is complete and concreted in. This stabilises the structure and holds it square during construction.
Double check all measurements and drilling locations before proceeding.
Regularly check framework for squareness and vertical alignment to make sure it hasn't moved during construction.
Regular washing or hosing of the inside and outside of your Stratco Heritage Outback will ensure it looks its best at all times. Refer to the "Selection, Use and Maintenance of Stratco Steel Products" brochure for complete details of maintenance requirements.
