What it is

A small web shop or marketplace store selling aluminium sheet, bar, tube and sections in small sizes. You buy from larger stockholders or mills, and either hold a modest stock or have orders sent on to the customer.

Your first three steps

  1. Open trade accounts with two or three UK stockholders and compare prices, minimum orders and delivery terms
  2. Pick a narrow range (for example sheet and flat bar in popular sizes) and list it on a marketplace or simple web shop
  3. Test a few orders with a small stock or direct delivery, then check your margin after postage, packaging and fees
Who pays

Makers, hobbyists, model engineers, small fabricators, sign makers, van converters and tradespeople who only need a few pieces.

How it makes money

You sell at a mark-up over your trade buying price, plus a charge for cutting to size and delivery. Orders are small, so a tidy range and good listings matter.
