Horizontal Beam: Length Range 36-144 inches, Height 3-8 inches

Component Specifications

Definition

A horizontal structural member in storage racking systems designed to support palletized or unit loads between upright frames. It functions as the primary load-bearing element that transfers weight to vertical columns while maintaining system stability and alignment. Typically features standardized connection interfaces for rapid assembly and adjustment.

Working Principle

Distributes vertical loads through bending moment resistance to upright frames. Provides horizontal bracing to prevent rack sway under seismic or impact forces. Uses standardized locking mechanisms (teardrop, bolt-on, or wedge-lock) for secure attachment to upright columns.

Materials

Cold-formed steel (C-channel or box beam), ASTM A36 or equivalent. Yield strength: 36 ksi minimum. Galvanized coating (G60-G90) or powder coating for corrosion resistance.

Frequently Asked Questions

What is the difference between step-beam and box-beam designs?

Step-beams have a stepped profile for easier pallet placement and are lighter, while box-beams offer higher load capacity and rigidity with rectangular cross-sections.

How do I determine the correct beam capacity for my application?

Calculate based on maximum unit load weight, number of beams per level, safety factor (typically 1.67), and consider dynamic loads from forklift impacts.

Are beams interchangeable between different rack manufacturers?

Generally not interchangeable due to proprietary connection designs. Always use beams specified by the rack system manufacturer for safety compliance.
