Product overviewThe MEISER sheet metal profile grating Drainstep RH3 is a development based on EN ISO 14122-2 designed to provide increased protection against items falling through (ball ≥ 20 mm) while maintaining high drainage performance. The geometry achieves approximately 70% free cross-section and a maximum opening width of 20 mm. Steeply positioned bars deliver enhanced transverse rigidity suitable for industrial floors, platforms and stair treads.
