STRUCTURAL MEZZANINES

When considering optimizing your storage space, consider a mezzanine. Mezzanines are low-level stories used in warehouses, gyms, libraries, homes and many more applications. At times the cost of moving into a bigger lease not only costs more money, but also puts a halt on your day to day operations and can be solved by redeeming the pre-existing cubic volume to your facility. As a result these structural steel platforms can be used to reconfigure your plan, provide more production space and relocate areas of less importance to the 2nd or 3rd level deck.

DESIGN CRITERIA

Designing a mezzanine can be a straight forward process or a complicated one. There are many variables that play a role that are governed in the applicable use of mezzanines. One must consider for starters if the mezzanine has the ceiling height to be functional? Will it be used for equipment support or eventually expand as your business grows? As a structural platform, a mezzanine can be over designed to engineered to meet specification. One of the most important concerns to foreshadow is how much weight will the system support? Will it be a uniformly distributed load or a point load on a receiving end? This load will determine the approximate weight of the system and determine if the concrete slab of your facility can support your platform or require special footings. To be safe and meet all city or county compliance codes, one will need to conduct a slab and soil analysis with a local engineering firm or through your mezzanine manufacturer. Many customers that purchase a used mezzanine are unaware that the mezzanine’s structural column base and foot plates are sized to meet load bearing specifications. As a result, they do not forecast neither the weight distributed on the columns or the slab thickness to support the load. In this case a larger base plate does not even help eliminate the need for concrete footings.

FACTORS TO CONSIDER :

  • Determine how you plan to use the mezzanine, is it over designed for future expansion?
  • Make sure mezzanine column base plates are sized appropriately.
  • Determine and coordinate with your designer to configure your column layout.
  • Do guardrails and stairs meet the permitting agencies requirements and their code compliance?
  • Know your slab capacity and soil strength.
  • Do you have at least 14 ft of clear ceiling height?
  • Do your mezzanine materials meet ASTM specifications?
  • Is your mezzanine a modular mezzanine or a custom designed mezzanine?
  • If it is modular and purchased as a package deal, does it meet your size and load requirements and have the necessary components (i.e. staircase, gate. handrail, etc.)?
  • Are your flooring options suitable for your use to transport products
  • and equipment?
  • Have you selected a swing gate? If so, is it the best fit for its use?
  • Are all structural calculations performed by a professional structural engineer?
  • Are the engineering plans stamped by a professional engineer and ready for city submittal?
  • Are the mezzanine structural calculations stamped by a professional structural engineer and ready for submittal?
  • Is your installation team licensed and insured to meet city compliance?
  • Is it galvanized or powder coated?

FAQ on Mezzanine Floor Design Considerations

A mezzanine floor is an intermediate floor between the main floors of a building, often used in industrial and commercial settings to create extra space or a work platform.

Common flooring options include steel bar grating, diamond plate, resin decking and concrete. The choice depends on the intended use, load capacity, and safety requirements.

Handrails should be sturdy, at an appropriate height, and compliant with OSHA standards. Choices include steel and aluminium depending on the environment.

Stairs should be designed for safe and easy access. Considerations include the width, slope, tread design, and handrails, aligning with IBC codes and OSHA guidelines.

Access gates provide secure and controlled access to the mezzanine floor level. They are essential for operations with pallets or material that needs to be brought to the floor level intentded, especially in areas with forklift traffic.

IBC codes cover aspects like load capacity, egress, fire safety, and accessibility. For mezzanines, specific attention is given to structural integrity and emergency exits.

OSHA guidelines emphasize fall protection, railing heights, safe access, and load capacities to ensure a safe working platform.

Load capacity is crucial. It dictates the material choice and structural support needed to safely support the intended use without risk of collapse and very much delegates the purpose of the mezzanine floor.

This includes installing fire-resistant materials, fire sprinkler systems (when recommended), ensuring clear emergency exits, and adhering to IBC fire codes regarding spacing and egress routes.

Compliance with the Americans with Disabilities Act (ADA) is key. This may involve installing ramps or elevators, along with accessible stair designs.

Factors include space availability, frequency of use, load requirements, and compliance with safety standards set by IBC and OSHA.

Consider factors like purpose, durability, maintenance, safety (e.g., non-slip surfaces), and compliance with relevant building codes and standards.

Yes, they can be tailored to specific requirements, but always within the constraints of safety codes and operational functionality.

Regular inspections for structural integrity, railing stability, and gate functionality are important, along with general upkeep.

Non-compliance can lead to safety hazards, legal actions, fines, and in severe cases, closure of facilities.
