Steel Pergola Kits: What You Get and How a DIY Build Goes

A steel pergola kit is the frame and roof of a pergola, cut, drilled and made to size in a workshop, then shipped flat-pack for you or your builder to put up. Our kits come in set sizes from 3 x 3 m to 6 x 6 m or custom, in a Colorbond colour of your choice, supplied with the hardware. If you can dig footings, stand posts plumb and work safely at height with a helper, a kit is a realistic DIY project. If not, we install them around Adelaide, the Barossa, Murray Bridge and the Murraylands.

Because kits ship flat-pack, they suit people well outside Adelaide too, from Murray Bridge to Mount Gambier and Whyalla. Here are the questions worth answering before you fill in the kit quote form.

What comes in a steel pergola kit

Every kit is fabricated to order in our Mount Pleasant workshop and supplied with the hardware, ready for assembly. A steel pergola kit is built around:

• Steel posts and beams sized for the span, cut and drilled so the bolted connections line up on site.
• Purlins and bracing to carry the roof sheets and keep the frame square.
• Roof sheets in your chosen Colorbond colour, or unpainted Zincalume.
• The hardware to put it together: brackets, bolts and roofing screws.

Your written quote lists exactly what is in your kit. What is not in the box: concrete, the tools, and anything that depends on your site, like flashing into an existing roof line or extra posts for a sloping block. If you are attaching the pergola to the house, tell us what the fascia or wall is made of so we can talk through how it fixes on.

Choosing the size

The configurator has 3 x 3 m, 4 x 4 m, 4 x 6 m and 6 x 6 m, plus custom. A few things to measure before you pick:

• What goes under it. An outdoor table for six with chairs pulled out needs more room than people expect. Mark it out on the ground with string or a hose and walk around it.
• Clearance to the house and fences. Leave room for gutters, downpipes and a path, and check how close to the boundary you are allowed to build (see approval below).
• Height. Attached pergolas need enough fall on the roof for water to run off and still clear the door heads and gutters on the house.
• The sun. Afternoon sun from the west is the hot one in an SA summer. A pergola positioned to shade that side of the house earns its keep.

If your space does not suit a set size, choose custom and give us the measurements. Every kit is made to order anyway.

Choosing the finish

The configurator offers standard Colorbond, unpainted Zincalume, or a custom paint finish. Colorbond comes in the full range of colours, from Surfmist and Classic Cream through to Monument and Night Sky. Lighter roof colours stay cooler underneath on a hot day, which is worth thinking about for an outdoor area you plan to use in summer. If you are weighing a clear roof for more light, our guide to polycarbonate vs Colorbond pergola roofs goes through the trade-offs.

Footings and standing it up

The footings are where a DIY pergola goes right or wrong. Posts need to sit in concrete footings sized for the soil and the wind on your site, set out square, and at the right height so the beams sit level. On a reactive clay block or an exposed hilltop, take advice on the footing size rather than guessing.

The usual order is set out and dig, stand and brace the posts, pour the footings, let them cure, then lift the beams on, fit the purlins and bracing, and roof it last. Lifting beams overhead is a two-person job at least. Plan for a safe way to work at height, because roof sheets catch the wind.

Do you need council approval for a pergola kit?

A kit pergola is treated the same as one built by a tradesman. In SA, an open pergola with no solid roof and open sides can be excluded from development under Schedule 4 if it meets the size and siting limits, but a pergola with a solid roof (like Colorbond sheeting) is treated more like a verandah and usually needs approval. Heritage areas, overlays and building close to the boundary can change the answer. Our guide to council approval for carports, verandahs and pergolas in SA explains the rules, and the PlanSA zoning tool shows what applies to your block.

Sort the approval out before you order, because the drawings you lodge need to match the kit you build.

Freight, delivery and lead times

• Kits ship flat-pack anywhere in Australia, with freight quoted to your postcode, in writing, before you commit.
• Fabrication and dispatch usually take 2 to 6 weeks after your order and deposit are confirmed, depending on the product and our workload.
• Delivery is generally kerbside or to an agreed drop point with safe truck access, and you will need help on hand to unload.
• Check every part against the paperwork on arrival and tell us straight away, with photos, if anything is damaged or missing.

The full detail is in the shipping, freight and returns section of the kit quote page. Because each kit is made to your size and colour, double-check your measurements before you order.

Kit or built for you?

A kit suits you if you are handy, have a helper and the right gear, and are outside our install area or want to save on labour. Getting us to build it suits you if the block is sloping, the pergola ties into the house roof, you need it done before a set date, or you would rather not be on a ladder in January. We build custom steel pergolas across the Barossa, the Adelaide Hills, the Murraylands and Adelaide, and install kits around Adelaide, the Barossa, Murray Bridge and the Murraylands.

Want a shed or carport instead? The same kit system covers those, and the 3D designer lets you size it up first.
