Factory-fabricated W-beam, thrie-beam and parking barriers. Hot-dip galvanised finishes. Supplied to NHAI highway projects, airports, metro systems and industrial campuses across Telangana and Andhra Pradesh.
Sun Railings manufactures metal crash barriers at our factory in Jeedimetla Industrial Estate, Hyderabad. Our barriers meet MORTH specifications and are fabricated from IS 2062 Grade A mild steel, hot-dip galvanised to 85 microns for long-term durability in outdoor environments.
We supply W-beam crash barriers for national and state highway projects, thrie-beam systems for bridge parapets and high-containment zones, and painted MS barriers for parking structures and industrial campuses. All systems are available with custom post spacing, end terminals and transition sections.

Metal crash barrier (highway guardrail) is a roadside safety system using rolled steel W-beam or Thrie-beam sections, steel posts, spacer blocks and terminal ends — fabricated to MORTH drawings, hot-dip galvanized per IS 2629, with steel grade IS 2062. SR-MCB-01 is Sun Railings metal crash barrier product line — BOQ-meter supply, shop drawing support, and EPC/NHAI submittal packs from Jeedimetla for national highway, expressway, and industrial perimeter programmes.

| System | MORTH application | Deflection class | SR-MCB-01 package |
|---|---|---|---|
| W-beam (2-wave) | NHAI median & roadside | Standard highway | Post + spacer + terminal |
| Thrie-beam (3-wave) | High-risk curves, bridges | Higher containment | Enhanced edge protection |
| Industrial perimeter | Plant boundary, logistics yards | Project-specific | commercial barricade alternative |
Sun Railings supplies SR-MCB-01 metal crash barrier packages to EPC contractors, NHAI vendors, and state highway departments across India — meter-rate BOQ with post spacing per MORTH drawing, HDG coating certificates, and material test documentation for consultant approval.

Sun Railings fabricates W-beam and thrie-beam road safety crash barrier systems at Jeedimetla for EPC contractors, NHAI vendors and state PWD packages. As a crash barrier manufacturer in India, supply scope covers beam profiling, post fabrication, hot-dip galvanizing and BOQ-aligned dispatch — documented for consultant and PMC approval.
W-beam crash barrier manufacturers supply the double-corrugation profile for N2 containment on standard highway edges. Three-beam (thrie-beam) crash barrier systems add a third corrugation for H2 containment where impact severity and vehicle redirection requirements increase.
| Parameter | W-beam | Three-beam (thrie-beam) |
| Typical application | National and state highway roadside, median on lower-risk sections | Flyover parapet, bridge edge, expressway black spots, median transitions |
| Traffic conditions | Mixed highway traffic at standard design speeds per IRC alignment | Higher containment zones, steeper curvature, elevated structures |
| Impact resistance | N2 containment — standard deflection per IRC:119 | H2 containment — stiffer section, reduced dynamic deflection |
| Installation | Standard post spacing 1.33 m to 4.0 m; W-to-W splices per drawing | Heavier section; W-to-thrie transitions, overlap lengths and terminal details on shop drawings |
Highway crash barrier steel is hot-dip galvanized after fabrication to protect against corrosion in outdoor environments. Sun Railings galvanizing is batch-tested and traceable to dispatch bundles for NHAI and state highway material approval.
| Process | Hot-dip galvanizing per IS 2629 / IS 4759 after beam profiling and hole punching |
| Coating mass | Typically 550–600 g/m² (85 microns minimum) unless tender specifies alternate class |
| Inland highways | Standard HDG schedule suitable for Telangana and AP state highway exposure |
| Coastal applications | Verify coating mass and inspection frequency on consultant schedule; SS fasteners where specified |
| Documentation | Galvanizing test reports supplied with each lot for PMC filing |
Manufacturing scope and capacity statements for EPC prequalification are available on Sun Railings fabrication capabilities.
Crash barrier suppliers on NHAI and state highway tenders should align scope boundaries before manufacturing release so item-rate BOQs do not omit terminals, transitions or fasteners.
Contact Sun Railings for BOQ review and project references on highway and airport crash barrier supply.
What should an EPC contractor verify before awarding a crash barrier supply order?
Beam profile (W-beam vs thrie-beam), post spacing, steel grade, galvanizing class, terminal schedule and whether transitions are in the BOQ — mismatches here drive site variation claims.
How do crash barrier manufacturers price highway packages?
Per metre run for beam supply plus numbered lines for posts, terminals and fasteners once the typical detail is approved; kilometre lump sums are reconciled to the same BOQ structure.
What lead time applies to a 2–5 km W-beam highway order?
Typically two to four weeks from drawing approval and advance confirmation, subject to galvanizing batch scheduling; phased dispatch by chainage is standard on large EPC programmes.
Which certificates are mandatory for NHAI material approval?
IS 2062 mill test certificates, IS 2629 galvanizing reports, dimensional inspection records and the manufacturer compliance statement aligned to IRC:SP:84 schedules.
When should thrie-beam replace W-beam on the tender drawing?
Where the consultant specifies H2 containment — bridge parapets, flyover edges, median transitions and high-risk curves; not as a blanket substitution across the entire highway length.
Does Sun Railings support BOQ quantity take-off from IRC typical drawings?
Yes — beam lengths, post counts, terminal quantities and transition lengths can be reconciled to tender BOQs before manufacturing release.
Is factory inspection available before dispatch?
Pre-dispatch inspection covers profiling, punching, galvanizing batch ID and bundling; third-party inspection is supported on prior intimation for EPC workflows.
How is galvanized crash barrier supply coordinated to site installation?
Bundles are marked by km section; installation method statement covers post foundation, bolt torque and terminal fixing sequence per IRC:SP:55.
