aluminium sheets plate buy

  1. P

    Where can I buy aluminium sheets/plate?

    Hello I am looking for aluminum sheet/plate that is approx 2.5m to 3mm thick for my school's project. The size i'd love is around 20"x20" or if the store offer to cut for me would be the best... May I know if anyone knows the exact shop that i can go look for this material? Thank you soo much!
