Yes, PyroMania fire tables have a heat shield incorporated underneath the burner pan and can be placed on a wood or synthetic deck.

Legs are optional for PyroMania firepits, but fresh air must be able to pass under the fire table to safeguard against residual gas accumulation. Failure to allow proper ventilation may cause a fire or explosion. If installing PyroMania fire table without the optional legs, it should be placed on a hard level surface that allows proper ventilation through the ½” gap incorporated into the bottom. If the installation method blocks the incorporated gap, then an alternative method for allowing ventilation would be required.
Required minimum clearances to combustible materials:
Sides and back - 48 inches. Top - 72 inches.

All PyroMania firepits are made from GFRC (Glass Fiber Reinforced Concrete) which has a better ability to expand and contract than traditional concrete and much less likely to suffer from structural cracks. GFRC is considered a gold standard material for extreme weather which makes it the ideal material for outdoor fire features.
