Serving Mile End & the inner west
Mile End has been Adelaide's trade and transport quarter for a century. Bring us your CAD file, your drawing or your broken part - we cut, bend and weld the big stuff the small shops send away.

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.
Precision plate processing and heavy fabrication for the workshops, depots and trade businesses packed into Adelaide's inner west.
New drums, drum repairs, agitator and hydraulic motor repairs. We get your mixer fleet off the bench and back pouring.

Between Richmond Road, South Road and the rail yards, Mile End packs an extraordinary amount of trade into a small footprint. Transport depots, automotive workshops, steel merchants, engineering shops and the businesses that supply all of them - it is one of the densest working precincts in the state.
Dense also means tight. Mile End premises rarely have room for a plasma table, a press brake and the material handling that goes with them. So the plate work gets outsourced, and the question becomes who can turn it around without holding your job up for a fortnight.
We run CNC plasma cutting and folding for heavy plate in-house at Wingfield, fifteen minutes up Port Road. Send the file, we cut it. No file? Send the part or the sketch and we will model it first.
Overflow plate cutting and folding when your own capacity is booked or the plate is too thick.
Truck body modifications, chassis repairs, tray builds and ladder racks for the inner-west depots.
Profile cutting, brackets, gussets and plate packs delivered ready to weld.
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 lot of Mile End businesses use us as the back half of their own shop - we cut and fold, they assemble. Clean cuts, accurate bends, and a turnaround you can actually promise your own customer.
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.

CAD file, DXF, drawing or photo. We will come back with a price and a date.
Mile End is one of the areas we cover from our workshop floor. About 15 minutes via Port Road. Tap any area below to see what we build there.
Send us a DXF or a CAD file and we can go straight to the table. Engineering drawings and even hand sketches are fine too - we will model it up first and confirm the geometry with you before cutting.
We are set up for the heavy end of plate work - the thicknesses smaller Mile End shops generally send away. Tell us the material and thickness and we will confirm on the spot.
That is a good chunk of what we do. Plenty of inner-west engineering shops send us their profile cutting and folding when their own gear is booked out or the job is outside their range.
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 Mile End 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.
