Published by pultrx, the export partner for Henan Zhongsheng. This is a buyer planning guide; the manufacturer confirms project specifications in writing.
Start with one controlled order schedule
Create one line item for each combination of section, cut length, material and finish. Give each item a reference that appears on the drawing, quotation and packing list. Specify whether the quantity is pieces or total length and how the supplier should price it. State drawing units explicitly; do not leave a supplier to infer millimeters or inches from a screenshot. Keep the required delivery date separate from the supplier's confirmed production and transport schedule.

Define the dimensions that control fit
Issue a dimensioned drawing with its number, revision and approval owner. Mark critical mating faces, holes, cut ends and any tolerances your design requires. For hollow sections, identify which outside, inside and wall dimensions govern acceptance, and resolve conflicts before ordering. A photograph helps explain the application but cannot replace the dimensional requirements. If a supplier proposes an existing section, compare its drawing with your required interfaces before accepting the substitution.
| Product family | Additional RFQ inputs | Acceptance question |
|---|---|---|
| Fiberglass tubes | Outside size, bore, wall, cut length and mating components | Which dimensions and fit checks govern the hollow section? |
| Fiberglass rods | Diameter or section, length, end finish and required rigidity or flexibility | How will the ordered shape and any required bending behavior be checked? |
| Flat strips and boards | Width, thickness, length, flatness and proposed construction | Is this a solid strip, hollow board or another panel construction? |
| Structural profiles | Section drawing, connection faces, drilled features and design requirements | Which material or load evidence does the project engineer require? |
| Sheet piles | Interlock geometry, effective width, installed length and project drawing | Who approves the interlock fit and structural design? |
| Fiberglass grating | Molded or pultruded construction, panel layout, supports, openings and surface | Are bearing direction, cutouts, load and deflection criteria defined? |
| GFRP rebar | Engineer-approved bar schedule, size definition, surface form and qualification requirements | What tests and product identification must accompany the ordered bars? |
| Custom FRP profiles | Controlled section drawing, product function, material, quantities and sample plan | What must be approved before tooling or batch production is released? |
Describe the service conditions and required evidence
Explain where the product will be used, what it contacts and which loads, temperatures or exposure conditions the design must address. Identify a required resin or reinforcement only when it is part of the specification; otherwise ask for a documented proposal. Color is not a material grade. Fire, electrical, chemical or structural suitability requires evidence applicable to the selected product and intended use. Name the test method, acceptance criterion and responsible reviewer where your project requires them.
Separate catalogue references from approved supply documents
| Starting reference | Requirement to confirm | Order evidence |
|---|---|---|
| A tube or beam shown in a catalogue | Exact geometry, material and available supply option | Approved drawing and supplier quotation |
| A published product property | Applicability to the ordered section and required test method | Agreed report, sample plan or qualification record |
| A custom section concept | Feasibility, tooling scope and approval sequence | Approved tooling scope and identified trial samples |
Agree samples, inspection and change approval
State whether a sample, first article or inspection report is required before batch release. Agree sample identification, measurement locations, sampling scope and the criteria used to accept the order. Incoming checks can cover dimensions, quantities, labels, visible damage and the reports listed in the contract. Keep tooling inspection, finished-product inspection and project design approval as separate records. Assign an owner for deviations and require approval before changing an agreed drawing, material or finish.
Compare quotations on the same delivered scope
Ask the supplier to separate product price from tooling, cutting or machining, samples, testing, packing and freight. Record the quotation date, validity, currency, quantity basis and delivery terms with a named destination. Clarify minimum quantities, production lead time and what starts that lead time. Identify the manufacturer and contracting legal entity in the quotation. The lowest product unit price is not enough to compare offers with different inspection or delivery obligations.

Prepare the RFQ and keep the attachments together
- Choose the product family and complete one schedule row for each ordered variant.
- Attach controlled drawings and any project test or qualification requirements.
- List open questions, required supplier evidence and the person who can approve changes.
- Use the pultrx contact form to prepare the enquiry. When using email draft mode, attach your files in your email client and send the RFQ to inquiry@pultrx.com.
Follow the delivery instructions shown on the contact form. In email draft mode, download the requirements brief and add your drawings and completed CSV to the email before sending; preparing the draft does not submit the enquiry. If the form confirms direct delivery, retain that confirmation and follow up with the supporting attachments. Keep the supplier's responses with the same project revision so engineering and purchasing review one agreed scope.

Questions buyers ask
- Can I request an FRP profile quotation without a final drawing?
- Yes. Send the available dimensions, intended function and quantity, and identify the open details. A preliminary response does not replace an approved drawing and acceptance specification before production.
- Should I buy a pultrusion die to order finished profiles?
- An existing section may not require new tooling. A custom section can require a separately quoted tool or development work. Ask the quotation to identify tooling ownership, approval and charges; buying finished products does not require buying a production line.
- Does a catalogue dimension mean the product is in stock?
- No. Confirm the offered section, order quantity, production availability and delivery schedule in the quotation.
