X-FCM NG • Redundancy of fastening points is required. • Base metal vibration and stress effects (e.g. tensile stress effects) are considered. • For base material thickness 3 mm ≤ tII ≤ 6 mm rework of coating on the backside of the plate / profile may be needed. • Grating fastening system resists shear load by friction. • Grating fastening system is not suitable for shear load design, e.g. diaphragm. • Depending on surface characteristics, shear load up to 0.
