Pultrusion die
Grating T-bar pultrusion dies
A grating T-bar pultrusion die forms an individual continuous T-section for a pultruded grating system. Henan Zhongsheng publishes a customizable T-bar die listing without a fixed section size. The RFQ should define the T-profile and its assembly interfaces; this tooling does not establish the scope of grating assembly equipment.

Start with the section you need to form.
Check the grating route
Confirm that the project calls for continuous pultruded T-bars. A molded grating production process needs different tooling and equipment and is outside this product scope.
Define the assembly interfaces
Show how the T-bar meets cross members and supports. Identify holes or slots requiring later operations and ask whether any such equipment is included.
Keep load testing explicit
Provide the intended assembly test requirements and responsible party. A die dimensional report does not certify the load capacity of a finished grating panel.
Review the configuration with engineering before the quotation is finalized.

Specification
Configuration table
Published catalogue values are reference figures; the agreed configuration and acceptance criteria belong in the quotation. Unconfirmed values are marked TBD · ask factory.
| Parameter | Value |
|---|---|
| Die steel options | 40Cr, P20, Cr12, 38CrMoAl or H13; confirm grade on the die drawing |
| Cavity hardness (HRC)Catalogue hardness references vary; confirm material, treatment and inspection method per drawing. | TBD · ask factory |
| Cavity surface treatment | Heat treatment and hard chrome or nitriding; route to be agreed |
| Hard chrome thickness | 0.04–0.05 mm catalogue reference; confirm for the quoted die |
| Straightness and measurement lengthThe catalogue gives no gauge length, so it is not a usable straightness guarantee. | TBD · ask factory |
| Finished-profile dimensional toleranceAgree tooling dimensions separately from tolerances measured on cured trial profiles. | TBD · ask factory |
| Resin compatibility | Polyester, vinyl ester, epoxy, phenolic or polyurethane; confirm formulation and process |
| Service life before re-chrome (m) | TBD · ask factory |
| Lead time (working days) | TBD · ask factory |
| Heater supply: 380 V 50 Hz / 480 V 60 Hz | Confirm only if heating equipment is in scope |
| Control requirements, if controls are supplied | Confirm destination requirements, assessment documents and responsible party in the quotation; no certification assumed |
| FAT and trial-pull scope | TBD · ask factory |
| Payment milestones | TBD · ask factory |
| Spare-parts kit | TBD · ask factory |
| Warranty party | Henan Zhongsheng Composite Material Co., Ltd.; terms and exclusions to be confirmed in the contract |

Tooling workflow
Agree each step from drawing to trial
Use these stages to define responsibilities, interfaces and the evidence needed at handover.
- 01
Review the T-section
Agree flange width, stem depth, thickness and root radii on a controlled drawing.
- 02
Review the line interface
Confirm reinforcement guides, heating, gripping and die mounting for the proposed section.
- 03
Set trial and fit checks
Specify sample conditioning, longitudinal checks and any mating cross members for an assembly trial.
- 04
Review the acceptance record
Compare the agreed dimensional and fit results with the drawing and record any corrections before release.
Scope of supply
Define the supply package and its options
Request an itemized quotation against these lists. A catalogue description does not confirm that every item is included.
Core equipment and work to specify
- Die body and cavity finish: configuration to confirm against the approved drawing
- DFM and approval documents: deliverables and revision allowance to confirm
- Preforming guides and mounting interfaces: itemize quantities in the quotation
- Trial pull, samples and dimensional report: agree materials, duration and charges
Options and services to price separately
- Heating plates, thermocouples and controls: request a separate scope line
- Mandrels and supports for hollow sections: confirm whether included or additional
- Resin injection box and connection to existing equipment: price if required
- Refurbishment, replacement inserts and sample freight: request separate pricing
Cross-sections
Profiles covered by this die family
- Custom T-bar cross-section; dimensions to be agreed from drawing
- Flange, stem and root-radius details to be specified for the grating design
Prepare your enquiry
Send a brief that can be quoted
Include the drawings and requirements below so engineering can confirm the configuration, exclusions and lead time.
Include in your RFQ
- T-section drawing with flange, stem and root-radius dimensions
- Cross-member interfaces and downstream hole or slot drawings
- Resin formulation and reinforcement plan
- Existing line mounting, heater and puller information
- Dimensional tolerances, gauge length and assembly sample requirements
- Separate requirements for panel testing, secondary equipment and spares
Agree the acceptance evidence
- Measure flange width, stem depth, thickness and root geometry.
- Check twist and straightness over the agreed sample length.
- Verify fit with nominated cross members when an assembly trial is contracted.
- Check die marking, mounting interfaces and the agreed component list.

FAQ
Questions buyers ask
- What standard T-bar sizes are offered?
- The reviewed listing does not establish a fixed size range. Submit a section drawing and request written confirmation of feasibility and lead time.
- Is this a molded grating machine?
- No. This page covers a die for continuous pultruded T-bars. Molded grating equipment is a separate manufacturing route.
- Are drilling and grating assembly included?
- They must be separately identified in the quotation if required. Do not infer secondary machinery from the T-bar die listing.
- Does the die quote guarantee the panel load rating?
- No panel rating is established here. Agree materials, assembly design and finished-panel tests with the responsible engineering parties.
