Code requirements, material availability, and even material costs can affect the final design of the guardrail. By equating the component's applied Bending Moment to its Flexural Strength, the span of rail, L, (or post spacing) can be solved. The stronger the component, the bigger the value of span it can attain. The least span attained by any component will be the design post spacing or the permissible spacing for the railing system. The American and Canadian building codes refer to the rack design standards in which it is indicated that individual beam load capacity weights must be clearly displayed on racks.
