SYSTEM OVERVIEW
Built for secure, adaptable sign installations
Square posts support back-to-back or adjacent-side signage with strong torsional stability.
Inline zinc-coated steel provides durable corrosion resistance for roadway use.
Compatible anchor systems support yielding roadside installations when properly engineered and installed.
SQUARE POSTS
Perforated and Qwik-Punch® sizes
Standard posts use 7/16-inch pre-punched holes on 1-inch centers. Qwik-Punch models use 7/16-inch knockouts on 1-inch centers on all four sides.
| Tube size | Gauge / wall | Area | Weight | Moment of inertia | Section modulus | Radius of gyration |
|---|
Square tubing: ASTM A1011 Grade 50 steel. Galvanizing: ASTM A653. Values are manufacturer brochure specifications; confirm project requirements and availability with the quote.
ROUND SIGN SYSTEM
Round post and anchor sizes
Socket-and-wedge round systems provide corrosion resistance and 50 ksi yield strength from the inline galvanizing process.
Round posts are stocked in 10-foot and 12-foot lengths. Other lengths are available upon request. The 2.875-inch × 12-gauge configuration is used for anchors.
ANCHORING OPTIONS
Compatible installation systems
Single breakaway anchor
Ground-level installation using manual or power equipment; designed for minimum installation time.
Two-piece breakaway anchor
An outer sleeve adds double-wall thickness to create a yielding breakaway system.
Heavy-duty anchor
For larger posts, concrete, and higher-impact areas; heavy wall construction can eliminate a stiffener sleeve.
Stabilization sleeve
Supports soft, drop-off, loose, or sandy shoulders and attaches to the anchor and post.
Omni-directional anchor
Designed for easier installation and performance in loose-soil conditions.
Slip-base system
For larger signs where the post is too strong for a conventional breakaway function.
Important: Final post, anchor, hardware, embedment, and installation method must be selected for the applicable sign area, wind loading, soil, roadway, and agency requirements.
