Mastering Work Zone Safety: The Science Behind Arborist Lane Closures
Executing a proper lane closure for roadside tree work requires more than just deploying a few cones on the shoulder. Establishing a fully compliant advanced warning area is the absolute most critical step in protecting arborist crews from high-speed or distracted drivers.

To maintain an impenetrable safety barrier, traffic control equipment must perform flawlessly under stress. At Eastern Metal Signs and Safety, we manufacture the complete suite of products arborists need to execute safe lane closing procedures, focusing heavily on two non-negotiable elements: visibility and stability.
Maximum Visibility: Orafol Super Bright Retroreflective Sheeting
Roadside tree care frequently occurs in challenging lighting—deep tree canopy shade, early dawns, or during emergency storm clean-up. To combat this, our roll-up signs utilize Orafol microprismatic retroreflective technology. Unlike standard materials, this engineered sheeting actively catches and returns headlight beams straight back to the driver’s eyes. This extreme luminance ensures that the “Tree Work Ahead” warning is registered hundreds of feet earlier, providing motorists the necessary reaction time to slow down and execute a safe lane merge.
Maximum Stability: Wind-Deflecting Sign Stands
A work zone warning system is completely compromised if the sign is blown face-down into a ditch. Arborist sites face heavy, unpredictable crosswinds, the powerful aerodynamic draft of passing semi-trucks, and the localized exhaust from heavy wood chippers. Our heavy-duty sign stands are engineered with a specialized dual-spring, wind-deflecting system. Instead of fighting the wind and tipping over, the mast flexes to absorb the kinetic energy. This allows the base to remain firmly planted while keeping the retroreflective sign face upright, properly oriented, and highly visible to oncoming traffic.
Eastern Metal Signs and Safety has all the products an arborist needs to keep a work zone compliant and safe. We take deep pride in engineering and assembling these critical safety tools locally near Elmira and Horseheads, NY.
Equip your crews with tools built for the reality of the road.
