Crash Test

crash test
  1. As part of the rewrite of NCHRP 350 [NCHRP Project 22-14(2)], the MGS Barrier was successfully tested;
  2. With both the 5000-pound quad cab and 5000-pound 3/4-ton pickup trucks;
  3. With the 2425-pound small car at the 32″ rail height;
  4. The MGS Barrier has a greater construction tolerance: Was tested to 32″;
  5. Having all of the components of the MGS system tested at 27 5/8″ allows the states to both set a construction tolerance for the rail system and to overlay the road without adjusting the system;
  6. Both tangent and flared terminals were tested in the MGS configuration as an option;
  7. The MGS Guardrail Barrier offers many variables to accommodate the real-world site conditions;
  8. The SKT and FLEAT were successfully crash tested in the MGS configuration.

What is the thrie beam guardrail / crash beam barrier?

Thrie Beam is a standard guardrail panel designed to keep errant vehicles on the roadway. Its three-wave cross-sectional design provides greater strength and durability than the two-wave W-Beam rails. This robust construction results in higher impact endurance, making Thrie Beam especially suitable for transitional areas like bridge approaches.

What must the top rail of guardrail system be within plus or minus 3 inches of?

According to OSHA requirements, the top edge height of guardrail systems must be 42 inches, plus or minus 3 inches, above the walking or working surface. This means the top rail must be between 39 and 45 inches high. In certain situations, the height may exceed 45 inches, provided the guardrail system meets all other specified criteria.
