Floor-supported garage shelving is another site-built option. One method for constructing these is to form upright supports by running vertical 2x4 boards every 50 inches. Each 2x4 should rest on the floor and be attached to a rafter or ceiling joist at the top. Then, additional 2x4 boards are attached horizontally on edge between the uprights and particle board is used to create the shelf. Dimensions are usually 19-25 inches deep with 25 inches between each shelf. These are only suggested dimensions and can be adjusted to better accommodate the size of the items that will be stored.
When purchasing these types of shelves, you should ensure that they come with a protective coating such as chrome that will ensure the shelves resist rust and last a lifetime. The shelves with a protective coating will also look good for very long. The shelves can save you money in the long run because unlike wooden shelves, you do not have to recoat, repaint or replace them. You should therefore not worry about their initial prices, even though they may cost more than other shelves.
For industrial purposes, metal shelving is the ultimate choice as it is durable and strong for storing huge and bulky goods. These have shelved capacities that vary from 300 pounds to 1000 pounds. Shelving depths usually range from 12" to 36"; heights range from about 39" to 123"; and widths range from approximately 36" to 48". Metal shelving is generally placed in a movable passage so that maximum storage space is created.
