Pool Dictionary: G235 Steel to Gunite

G235 Steel

The type of galvanized steel typically used for inground pool walls. G235 steel has a 14-gauge thickness (about 1.9mm) and coated with 2-3/4 ounces of zinc per square foot. The zinc acts as a rust inhibitor mainly for ground water that may get near your inground pool.

Gunite

Gunite is a brand-name of a concrete application process that pumps and sprays a concrete mixture through a hose and gun. Pressure sprayed Gunite is easy to use to create curves and special shapes, making it ideal for forming walls, steps and the floor of custom inground pools, along with bridges, dams, canals, locks, tunnels and pipelines. Gunite is pumped wet through the hose, while an alternative option ‘Shotcrete’, is mixed with water at the gun nozzle.
