Materials

Perforated hardboard and similar systems are made of a variety of materials, each of which has different characteristics that affect the range of possible uses. Standard perforated hardboard is made of wood fibers, usually with the addition of

Hardboard will bend and warp with age and in the presence of moisture, and will sag under heavy weight (the exact weight is based on the dimensions and quality of the hardboard) unless secured to even weight distribution among several mounting points. Perforated wood is more labor-intensive to manufacture and will warp and splinter under heavy loads, but is sometimes selected for

Metal pegboard systems are usually made out of steel. Metal pegboards are usually mounted in strips, as it would be comparatively costly, cumbersome and inefficient to sell in larger sheets. Sufficiently thick metal pegboards will not sag between mounting points. Instead, the system's mounting on surfaces such as

beams or sheetrock will usually fail under a heavy weight before the metal pegboard does. Manufacturers advise customers to hang tools and other gear based on the estimated strength of the mounting points. High quality metal pegboard systems use

Exercise

Large vertical pegboard can also be used for climbing exercises, whereby athletes hold two large pegs to insert into the holes of the pegboard to move up the board.

Typical dimensions and layout

These dimensions apply to standardized hardboard systems. Other systems may use their own spacing.
