Steel scraps for welding

Hi All, I’m looking for some second hand/scrap steel to use for a project. I’m going to create a fire drum out of an old truck wheel and want to add some legs and increase the height with some lengths.

This is the type of product I’m looking for but 30-40mm wide: https://www.themetalstore.co.uk/products/2-metre-lengths-3mm-flat-bar?utm_source=google&utm_medium=product_feed&utm_campaign=products&gclid=Cj0KCQiAn4SeBhCwARIsANeF9DIdNgZwyf-Bfn4JNxBcpf77V-WNBmdbCSIFxwEvcuGek5xkr14Agk4aAkLuEALw_wcB

I’ll also be adding more ‘spikes’ to the top of it similar to this one : https://www.google.com/imgres?imgurl=https%3A%2F%2Fflashcraftart.files.wordpress.com%2F2015%2F04%2Fimg_4467-0.jpg%3Fw%3D380&imgrefurl=https%3A%2F%2Fflashcraftart.wordpress.com%2F2013%2F08%2F25%2Frecycled-car-wheel-bbq-fire-pit%2F&tbnid=1EwIBc6VbWd-uM&vet=12ahUKEwi7i5e678T8AhWhXaQEHWjJBgsQMyhbegUIARDMAg..i&docid=xEFXz3QTIPPGbM&w=380&h=285&q=truck%20wheel%20fire%20pit&ved=2ahUKEwi7i5e678T8AhWhXaQEHWjJBgsQMyhbegUIARDMAg
