Safe, reliable trailers start with strong structure
A strong chassis and correct mounts are the starting point for safe towing and fewer roadside problems. We focus on structure first because everything else depends on it.
That means better handling, shorter braking distances and less tyre wear. These benefits protect your tools, machines and family when you tow on local roads and the Sturt or Dukes Highway.
- We check load paths from coupling through the A‑frame to cross‑members and spring hangers.
- We spot early issues others miss — hairline cracks, elongated bolt holes and creep at weld toes.
- When work is needed, we offer staged options so you can keep trading while we restore strength.
We prepare for SA registration checks, fit and stamp VIN plates and send vehicles for DPTI inspection at Regency or Lonsdale when required. Our team uses abrasive blasting, chassis straightening and protective coatings as needed.
Choose routine servicing to catch small faults early and avoid larger problems later. Call 0447 100 145 to request a quote, book a service or arrange a structural check today.
How to spot structural risk: rust, cracks and metal fatigue
A few quick checks can reveal whether a unit is safe to tow or needs urgent attention. We focus on the load points and moving parts first, because failures there cause the worst outcomes on the road.
Drawbars, A‑frames and cross‑members that weaken load points
Look for bubbling paint, seam corrosion near the coupling and pitting around bolt holes. Cross‑members often fail from the underside; tapping with a hammer helps us judge wall thickness and decide if a replacement is needed.
Cracks at spring hangers, coupling mounts and chassis joins
Cracks usually start at weld toes or bolt edges. We watch for fine lines, rust trails or dust marks that show movement. Elongated holes or distorted plates mean a clear repair plan is required.
Fatigue signs: sagging frames, uneven tyre wear, noisy suspension
Sagging or uneven tyres point to a frame that flexes under load. Noisy suspension and creaks are warnings. We measure diagonals and ride heights as part of a safety-first check.
Professional inspections that meet SA road requirements
For secondhand or homemade units we prepare VIN plate fitment and drawbar stamping, and we guide DPTI inspections at Regency or Lonsdale. We document findings with photos and a simple risk rating, then offer clear options and an upfront price.
- Common fix: replace a cracked cross‑member and reinforce hangers to restore alignment.
- We check bearings, brakes and lights when we inspect structure.
- We provide honest photos, ratings and costed options so you choose fast.
| Issue | Quick check | Likely action |
|---|---|---|
| Drawbar / A‑frame | Look for bubbling paint, pitting, seam defects | Cut out and replace section; stamp drawbar VIN |
| Cross‑member | Tap underside, check under deck boards | Replace member or box‑section and reinforce |
| Spring hanger / welds | Inspect weld toes for fine cracks or movement marks | Re‑weld with correct procedures and gusset brackets |
| Fatigue signs | Measure ride height, check tyre wear patterns | Realign chassis, fit reinforcements and re‑test |
Action: Book a safety inspection on 0447 100 145 and we’ll show you the condition, options and a clear cost for any repairs.
Trailer rust repair Adelaide: our inspection, repair and re-spray process
Our service starts with a careful inspection so we know exactly what needs restoring and why.
Full structural inspection, measurements and safety checks
We measure drawbar straightness, chassis diagonals, hanger brackets and coupling plates. We photograph defects and record ride heights so decisions are clear.
Surface prep: abrasive/sand blasting, rust treatments and clean metal
We blast to bright metal, treat remaining corrosion and only then weld or coat. Clean surfaces give strong joins and longer finishes.
Welding and custom metal fabrication to restore strength
Where metal has lost section we cut out and fabricate new parts in quality steel. We follow correct welding procedures and realign frames if needed.
Protective coatings and paint re-sprays for long service life
We seal with primers and finish in durable 2‑pack paint suited to SA conditions. We also renew fasteners, brake lines and wiring while the unit is in for works.
- Real job: a tandem plant unit had the front cross‑member replaced, A‑frame plated, blasted and finished in 2‑pack; chains and fittings were replaced.
- We provide photos, measurement reports and a clear price before we start.
- We manage insurance and private jobs and can assist with VIN plate fitment and drawbar stamping.
| Stage | Key checks | Typical action | Time (approx) |
|---|---|---|---|
| Inspection | Diagonals, load points, ride heights | Report, photos, costed options | 1–2 hrs |
| Prep | Scale, coatings, contamination | Abrasive blasting, rust treatment | 2–4 hrs |
| Fabrication | Lost section, weld quality, alignment | Cut out, new steel, weld and align | 4–8 hrs |
| Coating | Surface profile, adhesion | Prime, 2‑pack paint and protective finish | 2–6 hrs (plus cure) |

Repairs, servicing and compliance to keep you on the road
Planned servicing and clear compliance steps stop small faults turning into costly downtime. We work with tradies and towing customers who value uptime and safety. Our goal is simple: detect issues early, fix what matters and keep you legal.
Scheduled servicing: brakes, bearings, lights and fasteners
We tailor a service plan to your workload and load rating so checks occur when they need to. Regular servicing catches small faults before they become breakdowns.
- Brakes: even operation checks, shoe/pad adjustment or replacement, magnets and cables, and breakaway testing.
- Bearings: clean, inspect, repack with quality grease and torque hubs to spec to avoid heat build-up.
- Lights & wiring: end-to-end testing, clean earths, new grommets to stop water ingress and keep you visible.
- Fasteners, tyres and suspension: torque critical bolts, check load ratings and note worn bushes or shackles.
Compliance support: inspections, VIN stamping and registration guidance
For secondhand or homemade units we prepare paperwork and stamp VIN plates, then guide you to DPTI sheds at Regency or Lonsdale for inspection. After structural work we supply photos and documentation to streamline registration and insurance claims.
| Service step | We do | Benefit |
|---|---|---|
| Pre‑inspection | Measure, photograph, report | Clear priorities and cost estimate |
| VIN & stamping | Fit plate, stamp drawbar VIN | Simpler DPTI registration |
| Post‑work pack | Documentation and photos | Faster inspections and insurance approval |
We plan around your calendar, stage works when needed and keep common parts on hand to reduce downtime. Call 0447 100 145 to request a quote or book a service and keep moving.
Materials and workmanship that last in SA conditions
We choose materials and methods that resist coastal salt, dust and heat so your unit lasts longer between services. Our approach is practical: use the right steel, follow welding standards and protect every surface with proven coatings.
Quality steel and welding
We specify steel grades suited to load and duty, and we follow fit‑up, pre‑heat and controlled cooling where needed. This reduces brittle zones and lowers the chance of future cracking.
Preparation and coatings
We blast and clean to bright metal, apply high‑bond primers and finish with durable 2‑pack paint for impact and chemical resistance. In high‑wear areas we add extra build or hard‑wearing finishes.
- Protect cavities with corrosion‑inhibiting treatments.
- Use correct fastener grades and anti‑seize where service access is needed.
- Document materials and batch numbers on larger jobs for warranty and touch‑ups.
| Item | Why it matters | Typical action |
|---|---|---|
| Steel grade | Matches load and duty cycle | Select grade and thickness; note batch number |
| Welding | Prevents cracking and weak zones | Fit‑up, pre‑heat, qualified procedures, controlled cool |
| Coatings | Extend life in salt and heat | Blast, prime, 2‑pack topcoat and extra build in wear areas |
Result: fewer unplanned stops and longer service intervals at a fair price. Call 0447 100 145 to request a quote or book a service.
Service, price and turnaround: what to expect

FAQ
What signs indicate a structural risk from corrosion, cracks or metal fatigue?
We look for thinning or perforation at load points such as drawbars, A‑frames and cross‑members, visible cracks near spring hangers and coupling mounts, sagging frames, uneven tyre wear and unusual suspension noise. Any of these signs warrants an immediate professional inspection to assess safety and required work.
How do you inspect and measure structural damage to ensure compliance with South Australian road rules?
Our team conducts a full structural inspection including dimensional checks, non‑destructive testing where needed and safety assessments of mounting points and welds. We document findings and advise on repairs required to meet SA standards, and can assist with VIN stamping and paperwork for re‑registration.
What process do you follow to prepare and treat corroded metal before welding or painting?
We perform abrasive or sand blasting to remove loose material, apply rust converters or inhibitors, clean to bare metal and then carry out any necessary welding or fabrication. After repairs we use primers and high‑quality 2‑pack topcoats or protective coatings to extend service life in local conditions.
Can you restore cracked or fatigued sections rather than replacing the whole chassis?
In many cases we can repair by cutting out damaged sections and fabricating new reinforcements, using certified welding procedures to restore strength. Where damage is extensive or compromises safety, we recommend section replacement. We provide clear quotes so you can compare repair versus replacement costs.
How do you ensure welded repairs are durable and safe?
We use qualified welders, correct filler materials and pre‑/post‑weld treatments as required for the steel grade. We perform visual checks and, when necessary, additional testing such as dye‑penetrant or ultrasonic inspection to confirm integrity before finishing.
What maintenance should owners perform to slow corrosion and fatigue?
Regularly wash and inspect chassis, keep drainage holes clear, touch up paint chips promptly, lubricate moving parts and check fasteners and suspension for play. Scheduled servicing of brakes, bearings and lights helps identify issues early and extends component life.
How long does a full inspection, repair and re‑spray typically take?
Turnaround depends on scope. A basic inspection and minor repairs can be done in a day or two, while complex structural work and re‑sprays usually take several days to a week. We provide estimated timelines with every quote and aim to minimise downtime.
Do you handle insurance claims and provide documentation for insurers?
Yes. We prepare detailed reports, photos and quotes suitable for insurers and can liaise directly where required. That makes both private and insurance repairs straightforward and transparent.
What materials and coatings do you use to withstand South Australian coastal and inland conditions?
We use marine‑grade primers where needed, galvanised or suitably specified steel components and 2‑pack polyurethane finishes for UV and chemical resistance. Combined with correct fabrication and surface prep, these materials deliver long‑lasting protection.
How do you price structural repairs and what factors influence cost?
Pricing is based on inspection findings, labour hours, materials, welding complexity and whether fabrication or part replacement is needed. We provide itemised quotes so you can see costs for labour, parts, coatings and any compliance services.
