I never use Aluminium Warehouse after they never done anything about my last order they screwed up. Despite being told their substitute sizes were no use before they even sent them, they still sent them, and then proceeded to do nothing about fixing it despite numerous phonecalls and emails.

Now, I either try local for larger quantities, or Metal Suppliers – Round Metal Bar– Stainless Steel Rod – Stainless Steel Rod – Stainless Steel Bar- Brass Rod – Brass Round Bar – Aluminium Rod when I'm needing smaller quantities. Metal and Plastic also dispatch your order in a reasonable time frame, unlike AW who seemed to only send it when they could be bothered, which was usually around a week after you placed the order.
