Important info

Sourced in an annealed state, our steel arrives in expansive plates, typically measuring around 2x1m. Customization is made by trimming these plates into strips, optionally at 40 mm widths. Minor warping/bends from cutting is common yet can be effortlessly remedied using simple straightening methods (straighten them over the knee, with a vise, or hammer and anvil).
