There are many types of folding tables. They can be organized into types based on construction: particle board, plywood, abs plastic, hollow plastic and aluminum.
Particle board have all but been replaced with hollow blow mold plastic tables that have light steel runners. They are an OK homeowner table but generally not suitable for commercial or church use. They just dont last and end up costing more unless they are used very gently used.
Commercial ABS Plastic commercial tables are used by hotels, convention centers, churches, conference centers, civic centers, recreation centers and the like. Mity-Lite is the undisputed king of the hill.
