Fixtures

FIXTURES

We normally use stainless steel grade 316 fixtures for our projects. On special request we can use grade 304 which is cheaper, however, this grade will stain (but not lose its structural capacity during its lifetime). Except for the prefabricated USA-made Simpson anchors we never use galvanized fixtures, since they will corrode within a few years. 
Our stainless steel rods are 1 meter long and be cut to the required length for the connection. We use stainless steel hexagon nuts and plain washers with the same quality as the rods, either 316 or 304.  If the rod ends are exposed and become visible we may use acorn nuts for beautification. The use of acorn nuts will incur some extra costs.  

The following connections will be made with steel rods, nuts, and washers:
♠  Main flooring beam (header) to columns,
♠  Main column to pedestal 
♠  Sub-flooring beams (joists) to main beams
♠ All truss chord connections 

Secondary connections will be accomplished using galvanized lag bolts. These bolts do not need to made be of stainless steel since they are fully embedded in wood and will therefore not corrode. As per our standard, the foundation anchors will be made from normal galvanized steel pins. On request, we can install prefabricated Simpson strong tie anchors. These anchors are in particular very effective when building in cyclone areas since they have a very high capacity to hold in the strong wind uplift forces.
