Product overview

## How to Specify Highway Guardrails for Project RFQs

Guardrail quotation should follow the road layout first: beam profile, [effective length, hole pattern](https://qymetaltech.com/w-beam-vs-thrie-beam-guardrail-rfq/), post spacing, terminals and transitions all need to match the drawing or local standard.

QY Metal Tech reviews road drawings, quantity lists, accessory schedules and export packing notes so beams, posts, spacers and bolt sets can be grouped for site installation instead of quoted as loose parts.

 



### Highway Guardrails RFQ specification path

 

| Road layout | Send plan drawings, section length, curve or bridge transition information before beam quantity is confirmed. |
|---|---|
| Beam profile | W-beam, thrie-beam or project profile should match the drawing, hole pattern and applicable road standard. |
| Posts and spacers | Post type, post length, spacing, spacer block and installation method affect the accessory package. |
| Terminals | End terminals, transition sections, reflectors and special fittings should be listed by location. |
| Coating | Hot-dip galvanized finish is common, but coating thickness or color should follow the project requirement. |
| Packing groups | Beam bundles, post bundles and bolt cartons can be marked by road section for installation. |

 

 





Standards reference

## Road standard, coating and accessory references

- Guardrail systems should follow approved road drawings, local highway safety standards and installation layout.
- Hot-dip galvanizing can be reviewed according to ISO 1461, ASTM A123/A123M or project-specified coating requirements.
- Beam profile, post section, spacer block, terminal and reflector details should match the drawing and accessory list.
- Final packing should group beams, posts, bolts and terminals by road section or installation sequence.

 



Specification examples

## Common Highway Guardrail RFQ Models

 

| W-beam guardrail | Common road barrier profile reviewed with matching posts, spacers and bolt hole layout. |
|---|---|
| Thrie-beam guardrail | Deeper beam profile used when the drawing or containment requirement calls for higher protection. |
| Galvanized beam package | Beams, posts, spacers, terminals, reflectors and bolts grouped by road section. |
| Terminal and transition set | End terminals, bridge transitions and special sections confirmed from the project layout. |

Use these expressions as RFQ shorthand, then confirm drawing standard, beam length, post spacing, terminals, accessories, coating and packing marks before production.

 

 

 

 



Applications

## Where Highway Guardrails Are Commonly Used

## Highway Guardrail Buyer Questions

 

W-beam or thrie-beam: which guardrail do I need?

Follow your project drawing, tender document or road standard. Thrie-beam is a deeper profile used where higher containment is required; if unclear, send the layout and containment notes for review.



Can you supply the complete system with posts, spacers and bolts?

Yes. Beams, posts, spacer blocks, bolts, nuts, washers, reflectors and special fittings can be quoted as one package. Terminals and transitions need the exact approved drawings.



Which coating is used?

Hot-dip galvanizing is standard. ASTM A123/A123M usually applies to fabricated parts and ASTM A153/A153M to hardware; coating thickness follows the project specification.



Can you make curved guardrail panels?

Yes. Send the chord, rise or radius with its reference basis, the orientation (inside or outside curve) and the tolerance from your drawing.



What documents come with the shipment?

Depending on your requirements: approved drawing, material certificates, dimensional and coating reports, fastener certificates, packing list and a deviation register.



How are guardrails packed for export?

Beams, posts and bolt cartons are bundled and marked by road section or installation sequence, so crews can sort parts on site.

System specification

## Highway Guardrail System Specification and Component Matching

Highway guardrail should be quoted as a matched system, not as an isolated beam. Confirm the W-beam or Thrie-beam profile, rail and hole pattern, posts, spacer or blockout, fasteners, terminals, transitions, coating, road layout and exact supply boundary.

 



### Guardrail system fields to confirm

 

| Field | What to send |
|---|---|
| Project basis | Road authority or engineer specification, drawing revision, location and approval basis. |
| Beam | W-beam or Thrie-beam profile, rail length, hole pattern, thickness or gauge wording and lap direction. |
| Post and offset | Post section and length, post spacing, spacer or blockout type and connection drawing. |
| Fasteners | Splice bolts, post bolts, washers, nuts and any project-specific hardware list. |
| Ends and transitions | Terminal, end section, transition, bridge or median interface and quantity by type. |
| Layout | Road section, curves or radius, slopes, obstacle interfaces, total length and sequence marks. |
| Finish | Coating specification, environment and any inspection or document requirement. |
| Supply boundary | Rails only or the complete rail, post, spacer, hardware, terminal and packing package. |

 

Compare [W-beam vs Thrie-beam guardrail](https://qymetaltech.com/w-beam-vs-thrie-beam-guardrail-rfq/), confirm [posts, spacers and bolts](https://qymetaltech.com/guardrail-post-spacer-bolt-rfq-details/), review [terminals and transitions](https://qymetaltech.com/guardrail-terminal-end-section-transition-rfq/), or use the [replacement-part matching guide](https://qymetaltech.com/replacement-w-beam-guardrail-parts-matching-rfq/). Then [send the approved system schedule and RFQ to QY](https://qymetaltech.com/contact/).



QY can review submitted component descriptions, drawings, quantity, finish, packing and destination for quotation. QY does not infer crash performance, interchangeability or road-authority compliance from a photo or component name; final system selection and approval remain with the project authority or qualified engineer.

 







## Highway guardrail engineering RFQ details

Source: QY-HGR-RFQ-01, Rev. 1.0 / 24 Jul 2026. A procurement and engineering clarification guide before project drawings and compliance evidence are approved; retain the original downloadable PDF.

**System boundary:** a loose W-beam is not an approved crash-barrier system. Rail profile, splices, posts, blockouts, fasteners, ends, transitions, foundation/soil and installed geometry must match the selected system. Changes can affect performance. This guide makes no blanket MASH, test-level or agency-approval claim.

On small screens, swipe wide tables sideways or focus the table and use the left/right arrow keys.

### Choose the procurement route



QY-HGR-RFQ-01 · Rev. 1.0 / 24 Jul 2026 · PDF page 2. Project entries are not assigned product values.

| Route | Customer input | QY output |
|---|---|---|
| Build to approved drawing | Issued project drawing, bill of materials and governing specification | Component offer with deviation list and document package |
| Match a named public standard | Standard designation, edition, class/type and agency supplements | Specification review; exact evidence confirmed before claim |
| Develop an RFQ package | Site, barrier function, geometry, environment and authority | Preliminary schedule for designer/agency review; not an approved safety system |



Define straight or project-curved W-beam/thrie-beam panels, posts and blockouts, complete fasteners and the specified finish. Terminals, transitions and crash cushions require the exact approved assembly and interface, not a generic substitute.

### Rail-panel manufacturing inputs



QY-HGR-RFQ-01 · Rev. 1.0 / 24 Jul 2026 · PDF page 3.

| Parameter | Required selection / entry |
|---|---|
| Profile | W-beam / thrie-beam / other approved profile |
| Nominal length | Overall and effective coverage length |
| Base metal | Grade, standard and certified thickness/gauge |
| Hole pattern | Approved drawing number and revision |
| End geometry | Standard splice / flared / special transition / custom |
| Curvature | Inside/outside curve, radius, chord, rise and orientation |
| Finish | Coating standard, class/grade, local repair method and appearance |
| Marking | Heat/lot, component ID, date or agency code as required |
| Quantity / packing | Panels per bundle, separators, lift points and destination |



### Curve geometry: record the basis and units

Supply the drawing’s independent geometry controls and orientation. For a circular arc defined by chord C and rise M, **R = C²/(8M) + M/2**. Use consistent units for C, M and R before applying the relation; the worksheet’s alternative units are not permission to mix mm, in and ft. State whether the radius is centerline or another drawing reference. This geometric relation is not a capacity or crash-performance calculation.

### Curve worksheet — project entries, not default dimensions



QY-HGR-RFQ-01 · Rev. 1.0 / 24 Jul 2026 · PDF page 3.

| Input | Definition | Record |
|---|---|---|
| Chord C | Straight-line distance between panel endpoints | \[project entry\] mm / in |
| Rise M | Maximum offset from chord to arc | \[project entry\] mm / in |
| Radius R | Centerline or reference radius — state basis | \[project entry\] mm / ft |
| Orientation | Inside / outside curve; traffic face; top/bottom | \[project entry\] |
| Tolerance | Project drawing tolerance | \[project entry\] |



### Posts, blockouts and foundations



QY-HGR-RFQ-01 · Rev. 1.0 / 24 Jul 2026 · PDF page 4.

| Item | Specify | Do not assume |
|---|---|---|
| Steel post | Section, mass/length, grade, length, holes and coating | A visually similar post is structurally equivalent |
| Blockout | Material, geometry, hole pattern and orientation | Thickness or recycled content without approval |
| Post spacing | Exact approved system drawing | A universal spacing for all soils and test levels |
| Embedment | Approved depth, soil class or foundation detail | Field adjustment without designer acceptance |
| Base-plated post | Plate, anchors, concrete, edge distances and design loads | Anchor capacity from bolt diameter alone |



### Fastener and interface schedule

For every connection, specify diameter, length, head form, nut, washer, grade and finish, plus thread position, shear plane and permitted projection. Use the approved tightening sequence. Kit parts by station, lot and drawing revision. Define exact terminal/transition drawings, connections and quantities before release; do not infer compatibility from a similar-looking component.

### Coating and handling controls



QY-HGR-RFQ-01 · Rev. 1.0 / 24 Jul 2026 · PDF page 5.

| Control | Required record |
|---|---|
| Process route | After-fabrication hot dip / metallic-coated input / duplex system / other |
| Governing standard | Project-specified standard and edition; component-specific applicability checked |
| Coating acceptance | Thickness/mass, sampling plan, appearance and permitted repair |
| Drainage / venting | Fabrication features reviewed before galvanizing |
| Handling | No damaging chains on finished surfaces; dry, ventilated storage |
| Traceability | Coating batch linked to component and inspection report |



Specify the applicable contract edition and grade/class: ASTM A123/A123M commonly applies to fabricated steel products and ASTM A153/A153M to applicable hardware; they are not interchangeable component requirements. Agree coating measurement locations and sample size. Inspect bare areas, runs, sharp points, damage and repairs against the governing standard, keeping holes, slots, threads and mating surfaces fit for assembly. Packing must prevent finish damage and wet-storage staining while preserving dry ventilation. Keep coating batch, component and inspection identifiers linked.

### Evidence supplied with the release



QY-HGR-RFQ-01 · Rev. 1.0 / 24 Jul 2026 · PDF page 6.
