Serving Mount Barker & the Adelaide Hills
Mount Barker is building faster than almost anywhere in South Australia. Concrete, civil and construction all need steel that turns up on time and fits first go.
About 45 minutes up the South Eastern Freeway

Kingpin Engineering re-barrelled two of our agitator drums and had them balanced and back on the trucks within the week. Pouring again with no downtime - proper engineering, not a patch job.
Needed a hook-lift skip bin built to suit our new truck. Sent Kingpin a photo of the fleet and they matched it exactly. Heavy-duty steel and it's copped a beating with no issues.
Brought a stack of thick plate and a CAD file to Kingpin Engineering for CNC plasma cutting and folding. Cut clean, bent dead-on spec, and turned around faster than anyone else would quote.
Built for a growth corridor: concrete equipment, site steelwork and the repairs that keep contractors moving.
New drums, drum repairs, agitator and hydraulic motor repairs. We get your mixer fleet off the bench and back pouring.

Learn MoreAdelaide Hills
Mount Barker has spent the last decade turning from a Hills town into one of the state's fastest-growing centres. New estates, new schools, new commercial developments - and behind all of it, a constant stream of concrete trucks, tippers, excavators and civil crews.
Growth corridors are hard on equipment. Mixer fleets run longer days, tippers do more cycles, and civil plant works in tighter windows. The gear that supplies a boom wears out faster than the gear that supplies a steady market, and the maintenance schedule has to keep up.
That is a large part of what we do for Hills operators: agitator drums built, re-barrelled and balanced; tipper and bin bodies repaired; access stairs, platforms, handrail and site steelwork fabricated to drawing. Forty-five minutes down the freeway, which makes deliveries and site measures straightforward.
We also cover
Agitator drums, re-barrelling, hydraulic repairs and chutes for the fleets pouring the growth corridor.
Access stairs, platforms, handrail, lintels, frames and structural steel fabricated to drawing.
Machinery repairs, custom brackets, trailer work and one-off builds for Hills businesses and properties.
At Kingpin Engineering, we’re more than just fabricators - we’re a team dedicated to setting the standard for what an engineering workshop should be. Founded by our director, the business was built on three non-negotiables: precision engineering, honest workmanship, and genuine customer care.
Kingpin Engineering started with a simple but powerful vision: to be the one workshop a customer could trust with everything - from a precision-engineered agitator drum to the one-off repairs most shops turn away. With years of hands-on experience, our founder saw firsthand how customers were bounced from supplier to supplier and let down by low standards - and knew there had to be a better way.
With that, the new standard for heavy fabrication and concrete engineering was born.
A remake costs a Mount Barker builder a week they do not have. Everything gets modelled and checked before it is cut, so what arrives on site is what the drawing said - dimensionally right, first time.
With engineering experience built over years on the workshop floor, every job at Kingpin starts with a clear plan - so you know the scope, the spec and the timeframe before we cut a single piece of steel.
That means we deliver the utmost care on every job we take on, from a 16m³ agitator drum to a one-off repair, without ever sacrificing attention to detail.
Backed by Certification: We wear our quality with confidence. You’re trusting us with serious equipment, so the least we can do is back it - with material certificates, welding procedure documentation and Australian-Standard engineering on every build that calls for it.
One Workshop, Every Job: The big concrete OEMs won’t touch your skip bin. The bin factories won’t roll a spiral blade. We do both - plus the cutting, bending, welding and mending others turn away - under one roof, on one invoice.

We will price it, build it and get it to site on the date we quoted.
Mount Barker is one of the areas we cover from our workshop floor. About 45 minutes up the South Eastern Freeway. Tap any area below to see what we build there.
Yes. It is about forty-five minutes up the South Eastern Freeway, and we deliver fabricated steel to Mount Barker, Littlehampton, Nairne and Hahndorf regularly.
We prefer to for anything that has to fit existing structure. A measure up front is far cheaper than a remake, and it is a short run for us.
We do - new drums, re-barrelling, refurbishment, balancing and hydraulic and drive motor repairs. Growth-corridor fleets work hard, so we schedule around your pour commitments.
We're a heavy fabrication and engineering workshop covering four main areas: concrete mixers and agitators, skip bins and waste bodies, CNC plasma cutting and bending, and custom fabrication and welding. Most workshops only do one of these - we do all of them under one roof, from precision-engineered agitator drums right down to one-off repairs.
We design and manufacture agitator drums from 6m³ to 16m³, built from high-tensile wear-resistant steel. Every drum is 3D CAD designed, dynamic-balance tested and water-capacity tested before it leaves our workshop. Need a size or spec not listed? We engineer to your requirement.
Both. We re-barrel and recondition worn drums, repair cracks, replace blades, re-balance and re-coat - bringing a tired agitator back to working life at a fraction of replacement cost. We also rebuild agitator drive motors and repair hydraulic motors and pumps (PMP, Rexroth and Eaton). Send us your drum or your truck and we'll tell you what's worth saving.
Yes. We build custom skip bins - Marrel, hook-lift, craneable and special-purpose - sized to match your truck and your job. Already have bins in your fleet? Send us a photo or a drawing and we'll build to match.
We do. Split floors, cracked walls, bent frames and general wear - we repair and reinforce bins rather than replace them, and get them back into service fast. Unlike the big bin importers, you can bring us a single bin without waiting on a container load or a minimum order.
Absolutely. Send us a CAD file, an engineering drawing, or even a sketch, and we'll cut and bend it on our CNC plasma cutter and press brake - including the big, thick steel smaller shops can't handle. No drawing? Our 3D CAD capability means we can design it, prove it on screen, then build it.
Yes - both steel and aluminium. Toolboxes, steps, brackets, tanks, frames and trade parts, including the aluminium work a lot of shops won't take on. Done properly and built to last.
Always. No job is too small to ask about and none too custom to quote. A snapped bracket, a bent chassis, a part that needs cutting, bending and welding into something new - walk in, describe the problem, and we'll tell you straight whether we can fix it, build it or improve it.
Yes. For OEM and export work we provide Australian-Standard design support, engineering and manufacturing drawings, material certificates, welding procedure documentation, and CKD/SKD container kits for local assembly.
The workshop is open Monday to Friday 8:00am to 5:00pm and Saturday 8:00am to 12:30pm, closed Sunday. We also run a 24/7 emergency callout for breakdowns - if something goes down outside hours, call (08) 7081 3155.
Yes. Our workshop is at 438-440 Hanson Rd, Wingfield SA 5013, and Mount Barker is one of the areas we cover regularly - supporting concrete operators, waste and recycling companies, transport fleets, mining and civil contractors and trade businesses. Give us a call on (08) 7081 3155.
Send us the details of your job - drawings or photos help - through our quote form or give us a call on (08) 7081 3155. The more detail you give, the faster and more accurate the quote.
