Verifying Concrete Slab Load Capacities

We eliminate the guesswork by conducting rigorous slab tests to confirm your concrete can handle a structural mezzanine. If your floor needs help, we engineer custom heavy-duty baseplates to safely distribute the extreme loads.

Seismic Base Shear Compliance for Mezzanine Structures

The deployment of a multi-tiered mezzanine necessitates complex structural bracing to counteract localized overturning moments and elevated centers of gravity. Erecting this secondary footprint in a North Charleston warehouse requires precise calibration of cross-bracing and moment connections to comply strictly with local seismic base shear and transverse deflection protocols.

    Calibrate cross-bracing against transverse deflection protocols.

Technical Inquiry: Q&A

Question

"What are the deflection tolerance coefficients for cold-rolled steel joists supporting a high-density Mezzanine in North Charleston, SC?"

Arjun Patel Racking System Installation Lead

For high-density industrial mezzanines supporting dynamic live loads (such as pallet jacks or heavy conveyor topologies), the joist deflection limit must not exceed L/360. Exceeding this threshold induces deck substrate micro-fracturing and compromises the moment connections at the primary support columns.

Mezzanine Load Limit FAQ

Q: How much weight can a mezzanine hold in my North Charleston facility?

We engineer them to hold anywhere from lightweight boxes and hand-picking shelves to heavy machinery. You tell us the load, we run the math.

Q: Can I drive a forklift on top of it?

No. Mezzanines are for hand-picking, conveyors, or pallet jack traffic. Keep the heavy forklifts on the ground floor where they belong.

Q: How do I get pallets up to the second level in my North Charleston warehouse?

We install heavy-duty drop gates. Your forklift raises the pallet up, drops it through the gate, and your guys up top pull it safely with a jack.
