I am not so sure if it’s too good to be true. China has a massive oversupply of steel and they’re continuing to produce and melt in quantities that far exceed global demand. So it makes sense some entrepreneurs are producing this stuff as an alternative to using steel in construction projects
The welds and general build quality look very good IMO. Stainless is usually pretty hard wearing. If you get them, let us know how you get on with them.
Was reading about a foundry company that refuses to buy Chinese steel. He was explaining the quality control was no existent, it was not to spec, and was barely usable.
