The NJB (New Jersey Barrier) is the international standard profile for rigid concrete road barriers, characterised by its distinctive sloped face that redirects vehicles without deflection during impact. Our barriers are precast, zero-maintenance, impact-tested, and available in standard lengths with pin-and-loop interlocking connection points.

NJB vs F-shape — which profile do I need?

For federal-highway contractor contracts, NJB (810mm) is the default; for MRT/LRT guideway works or heavy-industrial access where higher vehicles need redirection, F-shape (1,070mm) is often specified. The 260mm height difference creates a meaningful change in containment performance:

  • NJB (810mm) — the most common profile for highways and federal roads. Sloped face transitioning to vertical at top.
  • F-shape (1,070mm) — slightly different slope geometry. Used where truck/bus traffic is high or where the engineering specification calls for higher containment energy.

Muhibah manufactures both. WhatsApp your project's barrier requirement (typically stated in TMP or engineering drawings) for the right recommendation.

Concrete NJB vs plastic NJB — use case comparison

The NJB profile is available in both rigid concrete and flexible water-fillable plastic:

  • Concrete NJB (this page) — rigid, ~2,200kg, no deflection on impact. For permanent installation and heavy-vehicle containment. Ideal for highway shoulders, construction perimeter, MRT/LRT guideways.
  • Plastic NJB — HDPE polyethylene, water-fillable (~350–400kg when filled), deflects on impact to reduce vehicle damage. Ideal for temporary lane closures, event barricades, short-term traffic diversion. See our NJB Plastic Barrier page.

Delivery & installation across Malaysia

Standard lead time for NJB concrete barriers is 7–14 working days from confirmed PO, with delivery to site by prime-mover truck. Installation uses a hiab or crane — Muhibah can arrange, or your contractor can handle. Nationwide coverage: Klang Valley, Penang, Johor, Kelantan, Perak, Pahang, Sabah and Sarawak via regional logistics partners.

Frequently Asked

Frequently Asked Questions

What does NJB stand for?
NJB stands for New Jersey Barrier. It's the international standard profile for rigid concrete road barriers, first developed by the New Jersey Department of Transportation in the 1950s. The distinctive sloped face redirects vehicles without deflection during impact. NJB is the most common concrete barrier profile used in Malaysia for highways, federal roads and heavy-industrial applications.
What is the standard length of an NJB concrete barrier in Malaysia?
Muhibah's standard NJB concrete barrier modules are 3,000mm (3 metres) long, 810mm high, and weigh approximately 2,200kg per module. Modules interlock via pin-and-loop connections. Custom lengths (2m, 4m, 6m) can be manufactured for specific project requirements.
Is the NJB concrete barrier JKR-approved for Malaysian roads?
Yes. Muhibah's NJB concrete barriers are designed per AASHTO and Malaysian JKR/REAM guidelines for road-safety containment. Compliance certificates are supplied with every order. Common applications include federal roads, highway construction zones, MRT/LRT guideway perimeters, and major project boundaries.
How much does an NJB concrete barrier cost in Malaysia?
Pricing depends on quantity, delivery distance and installation scope. As a general guide, a single 3m standard NJB concrete barrier delivered to Klang Valley is in the RM 850–1,200 range per module for quantities of 20+ units. Bulk project pricing (100+ modules) is significantly better. WhatsApp +6012-351 3349 with your quantity and site location for a firm quote.
Do you only sell or also rent concrete NJB barriers?
Muhibah focuses on supply and manufacture. For short-term rental of barriers, dedicated rental specialists in Malaysia offer that service. For long-term installation, contractor project supply, or MRT/LRT guideway works, Muhibah is the direct manufacturer.
Can you deliver NJB barriers to East Malaysia (Sabah/Sarawak)?
Yes. Muhibah ships NJB concrete barriers to Sabah (Kota Kinabalu, Sandakan, Tawau) and Sarawak (Kuching, Miri, Bintulu) via roll-on roll-off (RoRo) shipping partners. Lead time is longer (3–5 weeks) due to sea freight, and minimum order quantities apply. WhatsApp for East Malaysia quotations.
