Cracked uprights, broken cage gates, worn hinges and tired trays. We repair or rebuild trailers and trays, in the workshop or on site.
NL Welding and Fabrication repairs and rebuilds trailers and trays at our workshop in Nairne, South Australia, or on site if the trailer cannot be moved. A recent job was a cage gate where the upright had cracked around the weld. We replaced it with a new length of slightly thicker steel to take the work that trailer gets.
Trailers shake and flex on every trip. Cracks usually start at welds and where two pieces of steel meet, and water sitting between them starts rust. That was the story on the cage gate above: it had cracked around the weld, with rust between the two pieces of steel.
Sometimes a single weld does the job. Sometimes the steel has had enough and a new length is the better fix. Send us photos of the damage and of the whole trailer or tray, and we will tell you which it is.
We had replaced the upright with a new length, that was also slightly thicker to take the abuse and the workload that this trailer gets used for.Nick, October 2026
Tell us what has broken and where it is. A photo of the break helps us work out what the job needs.
We work out the job and quote it, then you decide. Quotes are free.
Bring it to the workshop in Nairne, or we come out to you and fix it on site.
Yes, trailer frames can be repaired by welding. The whole crack has to come out first, and steel that has rusted thin is better replaced than welded over. Send us photos of the damage and the whole trailer, and we will tell you what the job needs.
There is no simple yes or no. In South Australia any alteration or modification to a trailer has to be lodged with Service SA on form MR7, and trailers over 4.5 tonnes are treated as heavy vehicles with their own rules.
If a job changes the trailer's structure, brakes or size, check with Service SA before the work starts.
Welding burns off the coating beside the weld, and water sits in the gap where two pieces of steel meet. That is what happened on the cage gate on this page: it cracked around the weld, with rust between the two pieces of steel.
It depends on the job. What changes the cost is how complex the job is, the metal, the time on site, the travel, and whether it is urgent or after hours.
We do not list prices because every job is different, but our quotes are free. Send us a photo and we will work out what it needs.
