Recent earthquakes serve as a reminder for businesses to prioritize the "safety of building signs," both in terms of materials and internal structure, as these directly impact long-term stability.
How are signs on high-rise buildings used?
Letter/logo signs installed on rooftops are designed to be "floating" and visible from a distance (e.g., from highways/business districts). These areas experience high wind forces and environmental vibrations, thus requiring strict engineering design and installation.
What are safe materials and structures like?
- Main Structure: Steel/powder-coated steel (supports weight and reduces long-term corrosion)
- Sign Surface: Zinc sheets or outdoor-grade acrylic, flexible, good shock absorption/temperature resistance
- Bolt Anchoring System: Secured with steel anchors/bolts to the floor or building wall, with additional mounting plates and support pads to distribute force.
Foundations and Piles: Must be designed and certified by an engineer
Even if the sign structure above is strong, if the foundations/piles are not designed by an expert engineer, there is a risk of tilting, sinking, or damage when exposed to wind forces or vibrations. The sign structure design should always be accompanied by a foundation design and certified by an engineer before installation.
- On-ground work: Use 4–6 bored/driven piles (depending on sign size and weight).
- Soft soil/earthquake-prone areas: Micro-piles or dry boring are recommended to increase stability and reduce vibration.
Production Techniques for Vibration Resistance
- Cut with high-precision CNC/laser.
- Reinforce the structure with Cross Braces (cross-shaped) to reduce swaying and twisting.
- Use a wide base + mounting plates (Bolt + Plate) connected to the building wall/floor.
- Create Drain openings to prevent water accumulation in the structure.
Benefits of Earthquake-Resistant Structures
Strength is at the heart of safety and brand trust.
- Reduces the risk of falling off/damage during vibrations.
- Extends service life to 5–10 years or more (depending on maintenance).
- Safe for surrounding lives and property.
Installing large letters with a crane
- Select a crane of 10–25 tons, according to the letter weight and lifting distance.
- Lift each letter sequentially, position, and secure with a Bolt + Plate system according to engineering specifications.
