Simpson Sst Connecting plate

NP perforated plates are made of Sendzimir galvanized plates, steel quality: S 250 GD + Z 275 according to DIN EN 10346. They offer corrosion protection of 275 g/m² on both sides, corresponding to a zinc layer thickness of approximately 20 μm. The advantages include versatility as a fastener, supporting wood and wood materials. There are many possible applications for perforated sheets in structural timber engineering, particularly for the production of trusses and collar beam trusses, in conjunction with Simpson Strong-Tie® CNA grooved nails or CSA screws. All perforated sheets may be calculated as thick sheets in accordance with EC5 or DIN 1052, allowing for the use of higher values of nail load-bearing capacities for the 1.5 mm plates.
