Roll Forming as a Metal Fabrication Technique for Pallet Racking
Pallet racking is a material handling storage system devised to store materials on pallets or skids. These are typically used in warehouses and factories to store large boxes, caskets and other heavy equipment. Pallet racks store materials in horizontal rows with multiple levels. As the numerous shelves in these racking systems need to bear a lot of weight, it is important to choose a high strength, resilient and durable metal for their production.
Of all the metal fabrication techniques, roll forming proves to be the most effective process for manufacturing pallet racks. Roll formed shelves for pallet racks are generally fabricated in a ‘teardrop’ style. They are referred to as ‘teardrop’ racks as the holes on the column of an upright shelving rack are shaped like a teardrop. Pallets rest on horizontal load beams which in turn are held in place by mounting clips. As the clips on teardrop configurations can be easily moved, the shelves can be adjusted for different heights to accommodate various sizes of load. This is very convenient for a factory or warehouse that may have to store a wide variety of product sizes.
Roll Forming Techniques
Roll forming is a technique that takes metal sheet typically in coil form, and passes it through a series of roller dies that progressively form the metal sheet into the required shape. Pallet manufacturers for warehouse racking, shelving and other storage systems can economically produce bulk volumes of steel pallets using the roll former equipment. Several secondary operations involved in the production of metals can be effectively combined in the roll forming operation.
Metal forming through roll former equipment is a continuous bending operation wherein a sheet of metal is plastically deformed along a linear axis. The metal sheet is passed through a series of roller dies and is progressively shaped to the required shape.
Shelving and Racking Equipment
Shelving and racking systems certainly need to be strong and durable. At the same time they should not be very heavy. One of the benefits of steel pallets fabricated through roll forming is that the produced materials are stronger and lighter as compared to their non-rolled counterparts. Roll forming also provides thinner walls to the metal, reducing OEM material costs.
Different kinds of pallet racking systems can be produced through roll forming. These include push back pallet racks, pallet flow systems, compact mobilised pallet racks and drive through pallet racking systems. Its flexibility to fabricate quality rich storage systems apart from a variety of other applications make roll forming the ideal technique for metal fabrication.
