⚠️ Before You Dig: Check local council regulations. In most EU and Australian areas, carports under 20 m² are permitted development. Always contact your local utility locating service before digging (e.g. Dial Before You Dig in Australia: 1100). The carport requires a flat, load-bearing surface — concrete, paved, or compacted gravel all work. Soft or uneven ground may need deeper footings.
💡 Time Planning: Spread the work across a weekend. Day 1: dig holes, set posts, pour concrete (Steps 1 — ~3 hr). Let cure overnight. Day 2: assemble frame, install roof, finish trims (Steps 2–5 — ~8 hr). This avoids downtime waiting for concrete to cure.
Step 1 — Dig Foundation Holes & Pre-Embed Posts
⏱ ~2–3 hours · Manual pages 1–2
Mark post positions. Refer to the layout diagram on page 2 of your printed manual. The standard carport width is 1984 mm — confirm your order dimensions match. Use string lines or a laser level to ensure all four positions form a perfect rectangle. Double-check by measuring both diagonals — they must be equal.
Dig the holes. At each marked position, dig a hole approximately 400 mm deep × 300 mm diameter using a post-hole digger or auger. In regions with frost, dig below the frost line. Remove loose soil from the bottom and sides.
Insert the aluminium posts. Place each 6005-T5 post into its hole. Use temporary timber bracing staked into the ground to hold each post upright — do not rely on the concrete to hold position during pouring.
Level and align. Check verticality with a spirit level on two adjacent faces of each post — front-to-back and side-to-side. Verify the post tops are all at the same height using a string line or laser. Confirm post-to-post spacing matches the manual exactly.
Pour concrete footings. Mix quick-set concrete according to the bag instructions. Pour around each post, filling the hole to just below ground level. Use a stick to tamp the concrete and eliminate air pockets as you fill.
Re-check alignment. Before the concrete begins to set, re-check all four posts for verticality and alignment. Small adjustments are still possible at this stage. Do not disturb the posts once the concrete starts hardening.
Let it cure. Allow 24–48 hours for the concrete to reach sufficient strength. Keep the area free of foot traffic and do not apply any load to the posts during this period. Cover with plastic sheeting if rain is forecast.
💡 Pro Tip: Slope the concrete surface slightly away from each post base to prevent water pooling. A small trowel-formed crown around each post adds years to your installation by keeping the base dry.
Step 2 — Assemble Main Beams & Framework
⏱ ~2–3 hours · Manual pages 3–6
Attach beam brackets. Bolt the main beam connection brackets to the top of each embedded post. These brackets are pre-slotted for precise alignment — finger-tighten the bolts initially; final tightening comes after the frame is fully assembled and squared.
Mount main beams. With a helper, lift each longitudinal main beam into the bracket slots. The proprietary clip-lock connector system seats each beam with an audible click — no welding, no complex fasteners. A light tap with a rubber mallet helps seat stubborn clips without damaging the QUALICOAT powder coating.
Install secondary beams. Position secondary cross-beams perpendicular to the main beams at the spacing intervals shown in your manual's frame diagram. These create the structural grid that supports the roof panels. Each connection point uses the same clip-lock mechanism.
Add cross-bracing. Attach diagonal cross-bracing members between the posts and beams. This is one of the most important steps — properly installed bracing gives your carport its 180 km/h wind rating (Category 2 cyclone / EN 1991-1-4) and 1.5 kN/m² snow load capacity.
Check square. Measure both diagonals from corner to corner of the frame. If the two measurements are equal, the frame is square. If not, gently push the frame into alignment before fully tightening all connections.
Torque all fasteners. Once the frame is square, use your socket wrench to tighten every bolt to the specification listed in the manual. Work systematically — start from one corner and move around the structure to avoid missing any connection.
💡 Pro Tip: Keep a bolt checklist as you torque. On a 30-year-rated structure, a single loose bolt at a post-to-beam connection can introduce movement that accelerates wear over time. Take the extra 10 minutes — it's worth it.
Step 3 — Install Roof Panels & H-Profile Connectors
⏱ ~2–3 hours · Manual pages 7–9
Identify the UV side. Each Bayer polycarbonate panel has a UV-protected side marked with a peel-off protective film. This side must face upward toward the sky. The UV coating blocks 99.9% of UV radiation (UPF 50+). Do not remove the film until Step 4.
Position the first panel. Starting from one edge, lay the first panel onto the frame beams. Leave an even overhang of approximately 50 mm on all sides. Align the panel's rib direction with the roof slope for proper drainage.
Join panels with H-profiles. Slide an aluminium H-profile connector onto the edge of the first panel, then butt the next panel into the opposite side of the H-profile. The double-channel design locks both panels together while allowing for thermal expansion (important in climates with large temperature swings).
Seal with EPDM gaskets. Press the EPDM rubber gasket strips into the top channels of each H-profile connector. This creates a fully watertight seal that blocks rain, dust, insects, and driven snow. Ensure the gasket runs the full length of every connector — no gaps.
Maintain the drainage slope. Throughout panel installation, confirm a minimum 5° slope toward the designated drainage edge. Use your spirit level frequently. Insufficient slope causes water pooling, which can lead to algae growth and accelerated wear.
Secure the panels. Fasten each panel to the frame beams using the provided self-tapping screws with neoprene washers. Drive screws through the panel into the beam below at the spacing intervals shown in the manual. Do not overtighten — the neoprene washer should compress to about half its thickness, not bulge or flatten completely.
💡 Pro Tip: Install roof panels on a calm, dry day. Large polycarbonate sheets act like sails in even moderate wind. If conditions are breezy, have your helper hold each panel steady at both ends while you fasten it — one unexpected gust can crack an unsecured panel.
Step 4 — Install End Caps, Trims & Final Tightening
⏱ ~1–2 hours · Manual pages 10–11
Install post-top end caps. Press the aluminium end caps firmly into the open tops of all four posts. These prevent rainwater from entering the hollow post interior, which would otherwise become a breeding ground for mosquitoes and a trap for debris.
Cap beam and H-profile ends. Fit end caps into every exposed beam end and every H-profile connector end. An uncapped profile end is an entry point for water, insects, and dust — every open end must be sealed.
Attach fascia trims. Clip or screw the decorative fascia trim profiles along the exposed edges of the roof — typically the front and side edges. These trims hide the cut edges of the polycarbonate panels and give the carport a clean, professionally finished appearance.
Re-verify drainage slope. Place your spirit level along the roof panels one final time. Confirm the 5° slope is still intact. If the structure has settled slightly during assembly, adjust fasteners now.
Full torque check. Walk the entire structure systematically — every post bracket bolt, every beam clip, every panel screw. Vibration during assembly can loosen connections. This is your last chance to catch and correct anything before the carport goes into service.
Remove protective film. Peel the UV-side protective film from all polycarbonate panels. Do this last to keep the panels scratch-free throughout assembly. Pull slowly and evenly to avoid leaving adhesive residue.
💡 Pro Tip: If you plan to add guttering later, leave the fascia trim on the drainage edge uninstalled for now. This saves you from having to remove it when fitting gutters. The edge will still look clean thanks to the H-profile connectors and panel overhang.
Step 5 — Final Inspection & Quality Check
⏱ ~30 minutes · Manual pages 12–13
Structural walk-around. Visually inspect every connection point — bracket bolts, clip-lock joints, panel screws, cross-bracing attachments. Look for any signs of incomplete seating, misalignment, or gaps. Run your hand along all accessible connections — you'll feel looseness before you can see it.
Test rigidity. Push firmly on each post from multiple directions. Push on the main beams. The entire frame should feel completely solid — zero wobble, zero movement. If anything shifts, locate the loose connection and re-torque it.
Water-test the roof. If you have access to a garden hose, spray the roof for 2–3 minutes and inspect the underside for drips. Pay special attention to H-profile joints, panel seams, and screw penetration points. Any leak indicates a gasket that needs re-seating or a washer that needs tightening.
Verify drainage. Pour a small amount of water onto the roof near the high end and watch it flow. It should run smoothly to the low edge without pooling anywhere. Pooling water indicates insufficient slope or a low spot in the frame.
Clean the panels. Wipe the polycarbonate panels with a soft microfiber cloth and mild soapy water. Rinse thoroughly. Never use abrasive cleaners, solvent-based products, or stiff brushes — they will scratch the UV coating and reduce panel lifespan.
Record your installation. Note the installation date, concrete type used, and any customisations. Keep the printed manual in a dry place for future reference. Page 13 of the manual contains the parts checklist — verify against it for your records.
💡 Ongoing Maintenance: Wash your carport once a year with mild soap and water. Check bolt tightness annually — especially after the first year as the structure settles. That's it. No painting, no rust treatment, no replacement parts needed. Your 6005-T5 aluminium frame with QUALICOAT powder coating is rated for 20–30 years with minimal upkeep.
Frequently Asked Questions
Where can I find the printed manual that came with my order?
Your 13-page installation manual is packed inside the hardware kit box. If you've misplaced it, contact our support team with your order number and we'll send you a digital copy by email.
Do I need planning permission?
In most EU and Australian regions, carports under 20 m² are permitted development and do not require planning permission. Always check with your local council before ordering — rules vary by area, especially in heritage or conservation zones.
Can I install this on my own?
We strongly recommend two people. While the pre-drilled frame and clip-lock connectors make the process straightforward, main beams and roof panels are large and require a second pair of hands for safe handling. Attempting it solo risks injury and damage to components.
How long does the concrete need to cure?
Standard quick-set concrete reaches sufficient strength in 24 hours for light loading. For full structural strength — especially before any significant wind — allow 48 hours. Do not proceed to frame assembly until the concrete has fully set.
What if I need a custom size?
The standard width is 1984 mm but we manufacture custom dimensions for both B2B clients and homeowners. Contact our team with your measurements for a tailored quote. Standard sizes ship in 15 days; custom orders may extend lead time slightly.
What's the difference between the 6 mm, 8 mm, and 10 mm panel options?
All three are Bayer UV-stabilised polycarbonate with the same UV protection. The difference is in hail resistance and rigidity: 6 mm — standard for most residential use; 8 mm — recommended for areas with occasional hail; 10 mm — maximum strength for regions with frequent storms. Select your thickness at checkout.
Can I install the carport on soil or grass?
The carport requires a stable, load-bearing surface for the concrete footings — concrete slab, paving, or well-compacted gravel all work. Soft soil or lawn may require deeper footings and professional assessment. If in doubt, consult a local builder before starting.
