What is the standard material used for securing a grease interceptor/separator?

The standard material used for securing a grease interceptor or separator is threaded rod and steel strut braces. This choice is appropriate because grease interceptors are typically heavy and require robust support to ensure stability and proper function. Threaded rods can provide adjustable tension and are strong enough to hold the interceptor in place, while steel strut braces offer additional support by distributing the load, making the installation secure against movement or displacement.

Other materials, like wooden beams, are not ideal due to their susceptibility to rot and degradation in a wet environment. Plastic ties, while lightweight, lack the necessary strength and durability for such heavy installations. Concrete anchors can be useful in certain situations, particularly for anchoring to concrete surfaces, but they do not provide the same level of adjustability and structural support as threaded rods and steel strut braces.
