RIB-BAK® U-channel posts provide greater strength (80,000 PSI
minimum yield) at load bearing points than other posts, which is why
they have found favor in the agricultural industry. Our high-tensile
strength (140,000 PSI minimum) allows more weight to be distributed per
post, requiring fewer supports per acre.
The posts are easily installed. Using a
conventional power post driver, they can be driven in place in
approximately 30-40 seconds even in the harshest soil conditions, less
than one-fourth the time required for a comparable pine post. No
drilling or backfilling necessary.
RIB-BAK® posts are much stronger than wood,
and will not rot or carry disease.
In addition to economy, another benefit of
U-channel posts are the holes running the length of the posts, which
allow side pieces of U-channel or other steel components to be bolted
to the support posts.
Tests held at UC DAVIS Research Facility at Oakville .
• Posts driven to a DEPTH of 36" in compacted soil
• Pull tests were conducted by attaching a chain to
the test sample while concurrently connecting a chain to a deadman on
the opposite end. A "come-a-long" provided pull and a crane scale
measured load capacity in POUNDS at mid-point.
