The Model SD is a single piece, multi-sided, stainless steel lighting pole which is formed in an integral curved davit shape. The shaft is tapered octagon in heights up to 35' and
sixteen sided in heights from 35' to 50'. The pole is constructed from high strength type 201L
stainless steel with an after fabrication minimum yield strength of 60,000 PSI. The SD Series is widely used for street, highway and ramp lighting. Its one piece construction makes it ideally suited for high vibration applications such as bridge, overpass and median barrier mounting.
Optional bases for the SD are:
The enclosed "H" base is cold formed from the same type 201L stainless steel as the pole shaft, and is riveted and welded to a formed stainless steel base plate also made of type 201L stainless steel.
The standard anchor "A" base is made from 304L stainless steel plate and is welded to the pole shaft with two circumferential welds.
The stainless steel (AASHTO approved) breakaway "H" base is similar to the enclosed "H" base except that the base housing is fastened to the base plate with stainless steel rivets which are designed to shear under impact. (This base is designed to be replaced in the event of knockdown, allowing reuse of the pole shaft.)
