NJB Concrete Road Barrier — Manufacturer in Malaysia
Precast NJB (New Jersey Barrier) concrete road barriers manufactured in Malaysia. Heavy-vehicle containment for highways, federal roads and project sites. G7 CIDB registered manufacturer since 2009.
NJB concrete road barriers in Malaysia: precast 3-metre modules, 810mm high, ~2,200kg each, sloped New Jersey profile, designed per AASHTO and Malaysian JKR/REAM guidelines. Muhibah Konsortium Holdings is a G7 CIDB-registered manufacturer in Bandar Baru Bangi, Selangor — supplying federal roads, MRT/LRT works, highway construction zones, and major project boundaries since 2009. Lead time 7-14 days, nationwide delivery including Sabah and Sarawak, no foundation required for installation.
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 vs water-filled — choosing the right barrier
| Use case | Concrete NJB | Plastic NJB (water-filled) |
|---|---|---|
| Permanent installation | ✓ Best | ✗ Not suitable |
| Temporary lane closure | ~ Heavy to move | ✓ Best |
| Heavy-vehicle containment | ✓ Best | ~ Limited (deflects) |
| Event barricades | ✗ Overkill | ✓ Best |
| MRT/LRT guideway works | ✓ Best | ✗ Not suitable |
| Construction perimeter | ✓ Best | ~ Acceptable |
| Weight | ~2,200 kg | ~350-400 kg (filled) |
| Movability | Crane required | 2-person handling (empty) |

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.
