Metal is the main component in several building applications, and it isn’t easy to imagine constructing buildings without it. Warehouse buildings are large plain buildings used by manufacturers, wholesalers, exporters, importers, customs, and transport businesses to store goods.
Pre-engineered metal warehouse buildings are popular, and 95% of their construction is made of steel. Steel has different variations, and the suitable metal depends on your intended use. Different types of steel have distinctive properties as well. Here are four tips for selecting the right metal for warehouse buildings.
1. Tensile Strength
You need to check the tensile strength of the steel you plan to use and see how much tensile stress it can handle until it leads to brittle or ductile failure. Tensile strength refers to the resistance of a material to breaking under tension. It is used to specify the point when steel will go from temporary to permanent deformation.
The tensile strength is an important factor in metal warehouse buildings projects that will experience significant forces. The ductile failure is a preliminary stage where the metal is pushed beyond the yield point leading to permanent deformation. Finally, the brittle failure is a stage where final measurements are taken.
Weldability refers to the ability to join material. Most metals can be welded, but some are easier to weld than others. The steel’s hardenability depends on its chemical composition. Steel with higher carbon content has higher hardenability and lower weldability. Metal experts mention that as metal’s carbon content rises, its weldability decreases.
Almost all metals can be welded, and steel is no exception. Stick welding is the most common welding used to join metals like steel, nickel, copper, aluminum, and iron.
Machinability refers to the ease with which you can cut the metal with a blade. If the metal is less machinable, you will need special tools to cut it, increasing the expense and time required to build a metal warehouse building.
Carbon steel has a 1% of carbon content. Therefore, steel machinability is directly related to carbon content. Experts mention the highest machinability “sweet spot” is around 2%. Hence, you need to look for steel that has 0.15% carbon.
Above 0.3%, the steel becomes harder, and therefore, the wear is faster on the cutting edge. Using less machinable steel (with higher carbon content) can increase the time and cost required in metal building construction.
4. Ductility and Formability
Ductility refers to the material’s ability to change shape without breaking or losing strength. For example, metals are often drawn into thread or wire for various applications. The steel ductility depends on the levels of alloy elements present in it. An increase in carbon content will increase the strength of steel but also reduce its ductility.
To construct a metal warehouse structure, you can opt for higher ductility steel to absorb more energy without rupturing. In addition, HD steel can be ideal for building side structures of metal warehouses to improve structural safety and prevent cargo leakage in case of a collision.
Formability refers to the degree of deformation that can be accomplished in a metal forming process. For example, the formability of the steel you plan to use can be measured by a bend test or a simple tensile test.
To sum up, these are a few things you should consider when selecting suitable metals for warehouse buildings.
