Product information

Product name


Product description

The product is a hot-dipped galvanized G90, Grade SS255 steel truss connector plate that is 0.91 mm thick and stamped with 0.0099 teeth per mm2. The teeth are 9.5 mm long and are spaced 15.9 mm on centre (o.c.) along the width of the plate and 25.4 mm o.c. along the length of the plate. The slots in adjacent rows are staggered.
