I have been checking into this company myself since I saw the original post a few days ago. I told the OP that prior to COVID, I traveled to Chine frequently. I also have come to find that their factory is in Yangzhou, which is a huge auto parts manufacturing area. Yangzhou is one of the cities I travel to regularly, so once I'm able to go back, I will schedule a factory visit and see their operation. What I have been able to tell so far is that they 3D scan OEM parts for their manufacturing process. This is a good sign. They also offer tubs, but only '79 and up. They make FJ40 doors, aprons, hoods, fenders, bibs, bezels, windshield frames, running boards, '79 and up half and full tubs (with cowl), top sides (offering soon), and FJ45 roofs. In addition, they are offering FJ60 front fenders and front doors.
This appears to be a huge company. They make aftermarket body parts for many many vehicles.
As someone who works in the steel industry, I can tell you that Chinese steel is good quality, provided the right grade is specified. Their steel industry is probably one of the most modern in the world, and many of their mills have been built in the last 20 years. On top of that, many of the mills themselves are made by the Germans or Italians. The Germans make the best rolling mills in the world. Most US mills are German.
