I got some ordered as I needed some quick for a job. They held up to plasma cutting and grinding (Aluminum) so far. For the cost they’re great to have to prevent a fire or item being burned.
I liked that it was big and thick it also had grommet in it if you need them...word of advise I'd the welding is to hot you could add water to the blanket to make it much better
These are a heavy-weight blanket that are at a great price. Used them to protect floors on a residential, metal grinding project. The grinding had to be done “in place” and these worked like a charm. Price was exceptional for my scope of work.
