Can these be painted? Using a metal primer prior to finish paint.

Asked by BW February 21, 2021

Answer

CB post base has galvanized finish which could be painted over given proper cleaning and preparation of surfaces. Note that galvanized finish on CB66 is recommended for interior dry service conditions. You'd need to consider CB66HDG, which has hot-dip galvanized finish, if the base is installed in exterior wet conditions. Note that required bolts are not supplied with the base. The bolts finish needs to match that of the base. American Galvanizers Association is a good resource for information on painting over galvanized finish. Here is a link to their web site: https://galvanizeit.org/

Answer

The CB is only tested/rated for vertical (uplift) loads. Except for the MPBZ moment post base, post bases do not provide adequate resistance to prevent members from rotating about the base and are therefore not recommended for non-top-supported installations (such as fences or unbraced carports). The top of the post must be restrained from moving horizontally by some other means, e.g., by tying the roof into a supporting structure or by adding knee bracing between the posts and beams. Alternatively, see the MPBZ for a post base that provides moment resistance for columns or posts. Thank you!

Im not sure as I Only purchased 2 but I would assume so if you purchase the required quantity. HD typically has bulk pricing for larger quantities. The column base pricing was the best I found when surfing the web.

Is this anchor suitable for a gate post.

Hot Dipped?

Asked by Homebuilder March 9, 2016

Answer

The CB66 is made from G90 galvanized steel which is galvanized by a hot-dip process (prior to the part being fabricated), however, this base is also offered in a post-fabricated hot-dipped version (CB66HDG). The CB66 (G90) has a low level of corrosion protection while the CB66HDG has a medium level of corrosion protection. Please see the Corrosion section of our website to determine the recommended finish for your specific application based on environment, type of treated wood being used, chemical retention, etc. Thank you!

These are massive and very heavy. They are exactly what I needed for 6x6 posts that were going to have a lot of sideways load put on them. This did the trick!

Used it for the base posts of my new cedar pergola. Posts were true 6x6 posts so I had to trim a little off of them. Guy at the local lumber store said cedar posts were not true 6x6 posts...but they were. But these Simpson Strong Ties are heavy duty and solid.
