Pallet Rack Beams
Pallet rack beams are the horizontal load support members that connect uprights and create shelf levels within warehouse racking systems. Capacities for pallet rack beams are given per pair. Engineered Products: a pair of 2.5” 16ga x 96” beams can hold up to 2,212 lbs.; a pair of 4 1/2” 14ga x 96” can hold up to 6,944 lbs.

What pallet rack beams are
Midwest Material Handling says Pallet rack beams are the horizontal load support members that connect uprights and create shelf levels within warehouse racking systems. Engineered Products says The most common types are “Roll Formed Step Beams” and “Structural C-Channel beams”. WH1 says Capacities for pallet rack beams are given per pair and The most popular beam sold is a 96” L x 4” face with 5000 lb. capacity per shelf level.
Capacity, face, and gauge
Engineered Products says A pair of 2.5” 16ga x 96” beams, for example, can hold up to 2,212 lbs., whereas, a pair of 4 1/2” 14ga x 96” beams can hold up to 6,944 lbs. SJF says Both the steel gauge and beam face height play critical roles in determining capacity. MMH says Beam capacities range from approximately 2,100 lbs. up to 9,100 lbs. per pair, depending on beam length and profile height. AK Equipment lists A beam rated for 5,000 lbs per pair doesn’t override an upright rated for 20,000 lbs total: both limits apply at all times.
Interchange and connectors
Midwest Material Handling says Standard Teardrop style is fully interchangeable, regardless of the Manufacturer or when it was built, and Most Manufacturers make a proprietary style which is all their own and is not interchangeable with any other brand. AK Equipment says Never assume that beams or uprights from different manufacturers are interchangeable, even when the dimensions are identical.
Deflection (L/180)
SJF says maximum allowable beam deflection is defined as L/180, where L is the beam length in inches and a 96-inch beam has a maximum permissible deflection of approximately 0.53 inches (96 ÷ 180). SourceBySpec says Beam deflection is limited to L/180, the beam clear span divided by 180, under RMI ANSI MH16.1.
