Introducing Ezy Guard Smart Barrier the next generation steel guardrail barrier providing MASH TL3 and NCHRP-350 TL4 containment. The superior design offers rapid installation, improved motorist safety and more meters of a barrier for your rupee.
Ezy-Guard SMART rails and Z-posts are manufactured from hot-rolled steel in accordance with AS/NZS1594/BSEN10025 Grade S355. The product is hot-dip galvanized in accordance with AS/NZS 4680/IS 4759, leaving no surface untreated.
The Z-post profile shields post edges from vulnerable road users and provides sectional strength when driving through difficult ground conditions. An Ezy-Carriage is used to secure the W-Beam rails to the Z-posts eliminating the requirement for blocking pieces and rail stiffening plates. This unique connection provides a soft ride down for the occupants, a smooth vehicle containment, and redirection.Features:
- Fully compliant with MASH TL3 & NCHRP-350 TL4
- Demonstrated containment and redirection of the 2,270kg pick-up truck traveling at 100km/h
- No blocking pieces or rail stiffener plates
- Fewer components facilitate rapid installation
- Z-post embedment depth is just 870mm
- Fewer components to purchase, savings on freight costs and faster to install
- A system width of just 200mm conserves valuable formation width
The supporting Z-posts contain smooth, rounded post edges and corners. In addition, the revolutionary design of Ezy-Guard SMART shields the top of the support Z-posts by positioning the top of the rail above the posts.
This eliminates a dangerous snag point and is a significant safety benefit compared to existing safety barrier designs. It’s fully crash tested and approved by Ingal MPR motorcyclist protection.Crash Test Details:
Ezy-Guard SMART has been fully crash-tested and evaluated according to the specifications for Test Level 3 (TL3) of the AASHTO Manual for Assessing Safety Hardware (MASH). The system has also been crash-tested in accordance with NCHRP-350 Test Level 4, this is the containment of an 8000kg truck impacting the rail at 80km/h and 15 degrees.
The MASH specification is an update to and supersedes the NCHRP Report 350 for the purpose of evaluating new safety hardware devices. The MASH TL3 crash test matrix requires the following impacts:
• 1,100kg car travelling at 100km/h and 25 degrees.
• 2,270kg pick-up travelling at 100km/h and 25 degrees.
The MASH TL3 test condition represents a 13% to 18% increase in impact energy when compared to the superseded NCHRP-350 Test Level 3.
