Check guardrail strength, stiffness, and code-style load cases with engineering-grade accuracy. Enter span and section details, choose material, and compare against concentrated and line loads. See bending stress, deflection, and pass/fail checks instantly, in US or metric units. Designed for designers, builders, and safety reviewers who need quick verification without spreadsheets. Includes customizable limits, material properties, and section presets too.
Use with engineering judgment. Actual code compliance may require additional checks (posts, connections, infill, system behavior).
Two independent cases: a concentrated load at midspan and a uniform line load along the top rail. The tool reports the envelope for stress and deflection.
Yes. You can change the allowable stress fraction (a multiplier on Fy) and the deflection limit ratio L/x to match your project requirements.
No. This calculator models only the top rail as a simply supported beam. Post bending, base plates, anchors, and fasteners should be checked separately.
Many standards require additional infill or panel loads. This tool does not check them. If applicable, evaluate infill panels and their fixings per your code.
Enter elastic modulus E and yield strength Fy for your material (e.g., steel, aluminum, wood). If you’re unsure, use manufacturer data or a trusted reference.
Results indicate whether the beam model passes the user-defined limits. Actual compliance depends on the full system and the specific building or safety code.
Yes. Choose the unit system at the top. Inputs and outputs switch accordingly, including default loads comparable to common industry guidance.
