Building-Mounted Channel Letters
Letter sets fixed to tower fascias and upper floors at height.

When the job is 100 feet up, experience matters. Highmark installs building-mounted, rooftop and tall pylon signage on commercial towers, hotels, hospitals and multi-storey buildings across Florida.
Specialised equipment, training and experience are not optional at elevation. Florida wind load requirements are among the most demanding in the country, and coastal locations require hurricane-force wind engineering before a sign is ever fabricated.
Permitting is heavier too: a standard sign permit plus structural engineering review, wind load certification and, in some jurisdictions, architectural approval.
Each of these needs a different combination of access method, rigging plan and electrical approach.

Letter sets fixed to tower fascias and upper floors at height.

Structures set and secured on the roofline of commercial buildings.

Highway and interchange pylons where reach and rigging are the constraint.

Identification and wayfinding across multi-level parking structures.

Engineered rigging plans where a bucket truck cannot carry the load.

SPRAT-certified technicians working from anchors on tight urban sites.

Elliott bucket trucks give us working heights beyond 100 feet. Where the load or the geometry rules that out, we move to crane operations with engineered rigging plans, or to SPRAT-certified rope access systems when there is no ground room for a lift at all.
More review up front, because there is no improvising at height.
Structure, anchor points and how crews will physically reach the location.
Wind load certification to Florida and, where applicable, coastal code.
Sign permit plus structural review and any architectural approval.
Bucket truck, crane or rope access selected and documented.
Executed by trained crews with full fall protection.
Electrical and structural sign-off, then municipal final.
