Nucor Steel Marion, Inc. is revolutionizing guardrail installation with a system that saves time and money.
The NU-GUARDT 31 system does not require the use of offset blocks - a simple
bolt assembly attaches standard W-beam guardrails to 5 lb per ft RIB-BAKR
U-channel posts, making installation quicker and cheaper than wood or I-beam
posts. NU-GUARD 31 can be used in either strong or weak post applications,
and the system is designed to work with standard W-beam guardrails (AASHTO
M-180, Class A or B, Type II).
The NU-GUARD 31 system is crash-test proven to guard against roadside
collisions with fixed objects or hazards, meeting the stringent NCHRP 350
TL-3 (MASH) criteria. The system is FHWA-accepted for use along roads or in
medians with design speeds up to 65 mph.
The RIB-BAK U-Channel steel posts come either galvanized- or powder-coated
to help prohibit rust, enabling the posts to last longer.
