Mezzanine Guidelines

Fully Engineered Systems- See if your mezzanine supplier has at least one full time Professional Engineer on staff.  Ask if he/she supervises all mezzanines designs.  You will be surprised how many companies don't engineer their systems.
Confirmed Certified Welders- All steel fabrication work should be performed by confirmed certified welders.  A mezzanine system failure could spell disaster for you, make certain all fabrication work is done by professionals.
Build to Code- Yes there are many mezzanine "fabricators" that don't even build their systems to code.  If you are unlucky enough to purchase one of these, you could face fines and/or be forced to remove the structure from your facility.  Even worse you could have a failure and personnel could be seriously injured or killed.  If you are in doubt, please ask for a confirmation in writing, it's for your protection.
Experience / Past Performance- Mezzanine systems are mostly custom products so every application is different and unique, experience matters!  Ask your supplier how many systems they have sold in the last 12 months.  Some mezzanine dealers sell one a year if they are lucky!  Also ask for references names and telephone numbers.  They should be able to supply you with at least a few satisfied customers within the last few months.
Warranty- A credible mezzanine supplier will issue a warranty in writing for their systems.  Usually a warranty will be at least five years but some last the lifetime of the mezzanine.  Mezzanines don't have many moving parts to go bad.  The only real issues are factory defects and low quality materials and/or engineering.  Factory defects will be noticed and corrected during installation so why are so many fabricators afraid to offer lifetime warranties?  Please, for your protection, get a lifetime warranty in writing before you buy.
