Blade & projecting signs
Blade signs — also called projecting signs — that hang perpendicular from a wall. We engineer the outrigger arm, the wall attachment, and the connection to handle wind and dead load.

Engineering notes
A few things we always check — and what code references we follow.
Outrigger is sized for the cantilever moment from wind load on the sign face plus dead load.
Wall attachment uses through-bolts in masonry or backing-plate-to-stud connections with full blocking spec.
Connections are detailed for the eccentric load — not just shear.

Frequently asked questions
Common questions about blade & projecting signs and engineering.
What is a blade sign?+
A blade sign — also called a projecting sign — hangs perpendicular from a building wall, making it visible to pedestrian and vehicle traffic along the street. They're common on storefronts and in downtown districts.
Can you design decorative scroll-arm mounts?+
Yes. We engineer both standard outrigger arms and decorative scroll-arm configurations, including historic-district designs that meet aesthetic requirements while carrying the structural load.
How do you handle the eccentric load?+
Blade signs create an eccentric load on the wall — not just shear, but a moment from the sign's offset from the attachment plane. We detail the connection and wall attachment for this combined loading.
What wall types can you attach to?+
We design blade sign attachments for masonry (CMU, brick), stud walls with blocking, and poured concrete. Each gets a substrate-specific anchor and backing design.
