What it is

A web store selling small-quantity metal (aluminum, steel, stainless, brass, copper) to people who can't or don't want to order full lengths or sheets. You buy from larger distributors or service centers, often with cut-to-size or drop-ship arrangements, and sell in small, ready-to-use pieces.

Your first three steps

  1. Pick a niche such as aluminum for makers or stainless for food equipment, and compare prices from 3 to 5 distributors
  2. Ask suppliers about drop-shipping, cut-to-size and minimum order terms, and apply for a wholesale account
  3. Set up a simple online store with a small product range and test a few orders to check shipping costs
Who pays

Hobbyist makers, welders, small fabrication shops, engineers building prototypes, woodworkers and builders who need a few pieces.

How it makes money

You sell at a markup over your wholesale cost, with extra charges for cutting and shipping. Repeat buyers and bundled kits (for example, a project's worth of tube and plate) lift the average order.
