AstralPool has a wide of range of gratings, with various assembly systems. From straight lines to angles of 45–90º, through to curves. Consisting of modular plates for straight or curved stretches (exterior radius of 1 or 2 m) with a quick-click assembly system (male-female), the grating has a certain degree of elasticity for assembly purposes, as well as preventing potential shrinking and expansion due to the effect of temperature differences.
