The fastening system is also very important in determining the maximum load capacity of shelving. Light duty wire shelving with tubular steel uprights typically utilizes a plastic collar fastening system. Medium and heavy duty shelving systems utilize a boltless design that incorporates single or double rivets to join the front/side supports to the uprights via the punched holes. Extra heavy duty or high capacity shelving is either bolted or permanently welded together, or may utilize special high strength, boltless fastening systems designed for extra heavy duty applications.
Shelving units in their basic form consist of a frame and decking material. The frame can be constructed out of a variety of materials with the most common being steel sheet. The thickness of sheet metal is called its gauge and the lower its gauge number is, the thicker the steel is. Steel sheet ranges from about 30 gauge to 8 gauge, with thinner 30+ material called foil and thicker 8+ material called plate. The steel sheet is formed into structural members with various shapes for different applications and load carrying capacities. The capacities can range anywhere from a couple hundred pounds to 30,000 pounds or more.
Twenty years ago, cars were much simpler to maintain and understand than they are today. Computerised engine management systems and adjustable fuel injectors are now commonplace, and special automotive diagnostic tools are required in order to make adjustments to the engine timing and fuel air mix, whereas in the past, these jobs could be done quite simply.
