At The Sign Shop, LLC we build the post from the bottom up. Starting with the base, we offer a slip over cover or a solid anchor base that is welded to the post. These anchor bases are of a monolithic design, or in other words, a single piece design. This single piece design means the base plate is part of the base and not welded on. A welded base plate would weaken the overall strength of the anchor base. Therefore, our anchor bases have a distinct advantage over bases where the base plate is welded on. Our slip over base covers are made in one piece which eliminates the unsightly seam that can open up over time on a clam shell style base cover.

All Sign Shop, LLC bases are made of ASTM 356 cast aluminum alloy which is a marine grade alloy to ensure long lasting beauty and strength.

The bases are designed to accommodate a 3, 4, or 5 inch diameter fluted or smooth post. Our standard heights are 8, 10, and 12 foot poles. The posts are made from ASTM 6061aluminum alloy heat treated to a T6 temper for durability and strength.

Finally, at the top of our post, the customer has a choice of one of our decorative cast aluminum post top finials. These post tops are made of ASTM 356 marine grade cast aluminum alloy to ensure long lasting beauty and strength.

Installation

Anchor bases come with 4 galvanized stainless steel bolts and hardware for proper installation. An anchor bolt pattern will be provided in advance of shipment when requested. Slip over covers come with 3 set screws, set at 120 degrees, to secure it in place on the pole.

Finish

These cast bases are painted with a durable polyester powder paint electro-statically applied coating or a liquid polyurethane finish. Prior to painting, the product goes through a 7 stage pretreatment process. This consists of: sanding which provides a uniform surface for paint application; a detergent rinse; a chemical etch to enable a solid paint adhesion; a cleansing rinse; a chemical sealer to ensure corrosion resistance; a rinse; and a heat drying process.
