Heavy duty shelving is made for large, heavy loads that surpass the maximum load capacities of normal shelving units. In warehouses, heavy-duty shelving is often utilized to hold oversized goods or large pallets. These units provide the necessary support for heavyweight cargo.
Heavy duty shelving units are available in an array of designs; these designs vary most notably by the dimensions of the shelves and the materials that produce them. Dimensions include height, length and depth, as well as weight capacity. If desired, shelving units can be made fireproof, mobile or chemical resistant materials as well. These characteristics may also be achieved by various metal treatments and stains. Heavy-duty shelving is generally made of hard metals like steel or stainless steel. Steel is an alloy whose major component is iron. It also contains a small amount of carbon, although it only contributes to less than two percent of the total composition of steel. The variance between steel and cast iron is that steel has increased malleability and decreased carbon content. Heavy duty shelving is also made from treated wood material, depending on the application. However, some sort of metal frame is often involved in the wood shelving units.
