Grade 6061 Hardened to T6 then Anodised
Perfection.... Is a wonderful achievement...
Production Process
Anodising is controlled oxidisation
It breaks the electrical conductivity that allows electrolysis,
Anodise can not chip or break off as it is not a coating, rather the conversion of the base metal surface to form a protective surface created through an electrolytic process.
Inside and out..
The anodising is complete protection.
The oxidisation forms on all syrfaces.
Both inside and out side on all profiles even inside the holes.
Separation of Metals
Separation of Metals
In addition to anodising, metals of different nobility are separated with either Tefgel, PET gaskets or in the case of Stainless U-Bolts a protective saddle to stop the bolt from damaging the protective anodised surface.
Bolted... Not Welded.
Why... Not Welded
When Boeing weld their Aircraft.... Then we at Spitfire will weld our Trailers....
Grade 6061 Aluminium Hardened to T6 and offers high strength, excellent corrosion resistance, and superior machinability and greater strength over other Grade of alloys which is why it’s chosen for applications that require tough, yet light material.
Aluminium is incredibly robust material and can be welded as long as it is in a static situation, such as a building structure.
However if aluminium is used in any mobile situation, such as an aircraft or a boat trailer it flexes.
This is why aircraft are never welded.
Because this is where the welding cracks.
Raw aluminium has a hardness of around T4, however when it is welded the weld heated strip can reach T6.
So this creates one piece of metal of two different hardness.
Actually it is not the weld that cracks, it is the soft metal beside the weld where vibration and flexing stress crack at the join.
We don't know of any aluminium boat trailer manufacturer, apart from Spitfire, that hardens their trailer.
The only welded part of a Spitfire Trailer is the winch post.
How do we overcome this metal hardness difference ?
To offset this metal difference, we weld this post and then harden it in its welded form ensuring the whole post including the weld is T6.
Then we anodise it.

Why a 10 Year Warranty ?
Established in 2014... and not one Warranty Claim on our Chassis.
Why no Warranty Claims ?...........3 reasons:
1. Spitfire Trailers, like Aircraft, are not welded, rather bolted together. Aluminium, in a static situation like a building can be as strong as steel. However in a mobile and turbulent situation, like an aircraft or boat trailer, Aluminium needs to flex to relieve stress. A weld on aluminium becomes very hard, the metal beside the weld is still soft. This flexing will crack the main metal, not on the weld, but beside the weld, where two metals of different hardness meet.
2, Another reason why Spitfire have never had a Chassis Warranty Claim is because we use the same Chassis for all our Braked Trailers under 3,500 kg. That is right. If you purchase a 1,200 kg, a 1,500 kg, a 2,000 kg a 3,000 kg ATM Spitfire Trailer... then, even though it might be shorter, that trailer has exactly the same chassis as our 3,500 kg Trailers.
3. Finally, Anodised & Hardened Aluminium. Correct us if we are wrong, but we believe Spitfire is the only Boat Trailer Company in the world to Anodised and Harden our Boat Trailers.
Why Anodise & Hardened... and how is it done.? Anodising is an intentional electrically actioned Oxidisation of the surface.
This Oxidation brakes the electrical conductivity which is necessary for electrolysis which occurs when two metals of different nobility are in contact and exposed to a liquid... i.e. salt water.
Hardening strengthens the Aluminium from T4 to T6.
How is this done ? Simple, we extrude the aluminium, cut it to length, CNC drill it, bend it to shape, return it to the oven and harden it to T6....then we Anodise it.... even inside the drilled holes are Anodised and protected.
Most importantly, it is Hardened and Anodised in its final bent shape. We can not be more professional.
Spitfire Trailers have forged a World Wide Reputation in providing the Highest - Quality Boat Trailers to customers in 11 different countries. Spitfire Trailers are made from Grade 6061 Aluminium, Hardened to a strength of T6.
The metal on Spitfire Trailers which is not Aluminium, is life long lasting 316 Stainless Steel.

Benefits of being a Spitfire Distributor.
Distributor Opportunity:
On July 1st 2023, the Australian Government introduced ROVER.
In simple terms, ROVER compliance, means that all companies manufacturing trailers must ensure that those trailers meet the same standards as new motor vehicles.
In short, every component or part must be certified and it's origin is traceable in case of recall.
This brings great opportunity to Spitfire Trailer Distributors, as many companies selling trailers and many trailer imports will not be able to meet these high standards and will drop from the market.
Spitfire Boat Trailers are recognised and celebrated as the highest quality boat trailer on the market and are exported to 11 countries world wide complying with each countries motor vehicle code.
Spitfire Trailers are manufactured from Grade 6061 Anodised Aluminium hardened to T6.
WE believe Spitfire to be the only boat trailer that is Anodised and Hardened.
ALL non-aluminium parts on a Spitfire trailer are 316 Stainless Steel.
Yet despite the highest quality, Spitfire Anodised, Hardened Aluminium and 316 stainless steel trailers can compete with and are often cheaper than galvanised steel trailers.
Benefits of a boat trailer business.
The boat trailer industry is unique in that 92% of customers are existing boat owners replacing a rusty or defective boat trailer.
Generally boats can last for 30 - 40 - 50 years or more, and be on their second or third trailer.
Traditionally boat trailers were made from galvanised steel, many of which fail after 10 - 12 or 15 years.
This creates an ongoing market demand for the hundreds of thousands of trailer boats sold over previous decades.
Replacing a rusty boat trailers is not an emotional purchase like buying a caravan or camper trailer, rather is is a purchase through necessity to continue to use or even sell a trailer boat.
Spitfire customers can be categorised as pretty much the same, they just want a quality lasting trailer at a fair and competitive price.
