In seaside locations in warmer environments the salt stuffed air deposits corrosive chemicals on obstacles
When exposed to these settings, weathering steel never creates the 'aging' that slows deterioration as in other much less hostile atmospheres. Within a couple of years significant area loss may result. The interior of box light beam barriers and the lap splice of w-beams can rust swiftly to the factor where the obstacle may end up being more harmful than the feature it was indicated to shield.

One holiday accommodation that has been tried is using zinc aluminum foil at the w-beam overlap additional reading where the zinc's galvanic action slows down the rust.

After that they damage to a sloped face that increases to 13 inches above the sidewalk on the Jersey barrier, however only up to an elevation of 10 inches in the instance of the F-Shape.
The Texas Constant-Slope Barrier is 1070 mm (42 in) high and has a constant-slope face that makes an angle of 10. 8 levels with respect to the upright. California created a Solitary Slope profile that makes an angle of 9. 1 levels relative to the upright (Crash Beams). The collision tests show that the performance of the Texas Constant-Slope Barrier approaches that of the Jersey-shape and the performance of the California Single-Slope Obstacle is equivalent to that of the F-shape.
