If you are a distributor, window manufacturer, or building materials brand looking to source fiberglass mesh or insect screen under your own label, you have come to the right place. OEM (Original Equipment Manufacturing) and ODM (Original Design Manufacturing) are the most common partnership models in our industry — and getting them right makes the difference between a smooth supply chain and a constant headache.
This guide walks you through every step of the OEM/ODM process with CredenTex, from initial specification to container loading. Whether you are new to private-label sourcing or looking to optimize an existing partnership, the information here will help you work more effectively with any mesh manufacturer.
1. OEM vs. ODM — What Is the Difference?
Before we dive into the process, it helps to clarify the two models:
| Factor | OEM (Original Equipment Manufacturing) | ODM (Original Design Manufacturing) |
|---|---|---|
| Who designs the product? | You provide existing specs; we manufacture to your requirements | We propose designs based on market needs; you choose and brand them |
| Best for | Buyers with established specifications, existing products they want replicated or improved | Buyers entering a new market or product line who lack in-house technical expertise |
| Customization | Fully customizable within manufacturing capability | Minor customization (color, packaging, label) on top of proven base designs |
| Lead Time | Longer (tooling/sample approval needed) | Shorter (existing production lines) |
| MOQ | Higher per SKU | Lower per design |
At CredenTex, we support both models. Many of our long-term customers start with ODM (using our standard product designs with their branding) and gradually transition to OEM as their market knowledge grows and they develop custom specifications.
2. Step 1: Specification & Quotation
The process begins with a clear understanding of what you need. The more detail you provide upfront, the fewer revisions and surprises later.
For Fiberglass Wall Mesh (Plaster / EIFS Reinforcement)
When requesting a quotation, please include:
- Mesh count: e.g., 4×4, 5×5, 6×6, 10×10 per inch (or per 25 mm)
- Grammage (weight): Target g/m² (e.g., 60 g/m², 110 g/m², 160 g/m²)
- Roll dimensions: Width (cm/inches) × length (m/yards)
- Coating type: PVC, acrylic, or combined — and target coating content %
- Color: Standard (white, blue, green) or custom (Pantone code)
- Application: EIFS, plaster reinforcement, marble backing, waterproofing, etc.
- Certification required: CE, ISO, third-party test reports
For Insect Screen (Window / Door Mesh)
- Material: Fiberglass (PVC-coated) or polyester
- Mesh count: e.g., 18×16, 20×20, 30×30 mesh
- Wire diameter: Typically 0.20–0.28 mm for fiberglass
- Roll width: Standard (1.0 m, 1.2 m, 1.5 m) or custom
- Color: Black, grey, charcoal, white, or custom (must specify RAL/Pantone)
- UV resistance requirement: Accelerated weathering test standard (if applicable)
- Packaging: Inner core diameter, shrink wrap, labeling, pallet type
What Happens Next?
Our sales team reviews your requirements and confirms feasibility within 1–2 working days. You receive a formal quotation with:
- Unit price (FOB / CIF / EXW — your choice)
- MOQ per SKU and per order
- Estimated lead time (sample and mass production)
- Packaging details
- Payment terms
We recommend using FOB (Free on Board) for first-time orders — it gives you maximum control over shipping and often results in lower total landed cost.
3. Step 2: Sample Development & Approval
Once the quotation is accepted, the sample stage begins. This is the most important quality gate in the entire OEM process.
Sample Types
| Sample Type | Purpose | Typical Turnaround | Cost |
|---|---|---|---|
| Stock sample | Reference from existing production; good for initial quality assessment | 1–3 days | Free (you cover shipping) |
| Custom sample | Made to your exact specification; the reference for mass production | 5–10 days | Free for first revision; nominal fee for additional revisions |
| Pre-production sample (PP sample) | Made from the same batch of raw materials that will be used in mass production | 3–5 days before production run | Included in order cost |
| Shipment sample | Random sample pulled from the final production lot before container loading | Before shipment | Free |
What We Include with Every Sample
- Labelled sample with product code and date
- Weight (g/m²) measurement report
- Mesh count verification
- Roll width measurement
- Color reference under standard lighting (D65)
Pro tip: Always keep a signed “golden sample” — a physical reference that both you and the manufacturer agree represents the approved quality. Disputes about “shade of grey” or “mesh density” are much easier to resolve when both sides hold the same physical reference.
4. Step 3: Production & In-Process Quality Control
After sample approval, the order enters production. This is where our quality control system (described in detail in our earlier blog on QC) takes over.
Production Timeline (Typical)
| Stage | Duration | Key Activity |
|---|---|---|
| Raw material procurement | 3–5 days | Order fiberglass yarn, PVC resin, packaging materials from approved suppliers |
| Warping & weaving | 5–10 days | Set up looms with correct mesh count and yarn tension; IPQC checks every 30 minutes |
| Coating & curing | 3–5 days | Apply coating, control oven temperature profile, monitor line speed |
| Slitting & rewinding | 2–3 days | Cut to ordered width, inspect for visual defects |
| Packaging | 1–2 days | Wrapping, labeling, palletizing per your instructions |
Total lead time range: 15–30 days depending on order quantity, complexity, and current production load. We provide a confirmed schedule at order placement and update you if anything changes.
During Production, You Can Expect:
- Mid-production update — Photo/ video of production progress
- Pre-shipment sample — Sent for your review before the container ships
- Inspection photos — Key quality checkpoints documented with timestamps
We welcome factory visits during production. If you cannot visit, a third-party inspection can be arranged at your cost.
5. Step 4: Packaging & Labeling
Packaging is where many OEM partnerships succeed or fail. The mesh inside might be perfect, but if the packaging arrives damaged or the labels are wrong, your warehouse will be unhappy.
Standard Packaging Options
| Packaging Element | Standard Options | Custom Options (OEM) |
|---|---|---|
| Inner core | Paper core, 76 mm ID | Specified ID, plastic core, reinforced core for heavy rolls |
| Roll wrapping | Shrink wrap (PE film) | Kraft paper + shrink wrap, polybag, custom outer wrap |
| Label | Product name, roll size (width × length), net weight, batch number | Your logo, barcode, QR code, handling instructions, custom format |
| Pallet | Wooden pallet (heat-treated per ISPM-15 for export) | Pallet size, load configuration, corner protection, banding type |
| Outer packaging | Stretch wrap on pallet | Full carton, partial carton, brand-printed outer wrap |
Labeling Requirements to Discuss
- Product label: Brand name, product code, dimension, net/gross weight, quantity
- Barcode / QR code: For your warehouse management system
- Handling symbols: “Keep dry”, “This side up”, “Fragile” — in your local language
- Certificate of Origin: Marked on outer packaging when required for customs
- Carton marking: If using cartons, the number of rolls per carton, carton dimensions, and gross weight
Provide a packaging specification sheet (PDF or image) during order confirmation, and we will match it exactly. We also keep a “packaging reference file” for each OEM customer so that reorders are consistent without re-explaining every detail.
6. Step 5: Pre-Shipment Inspection & Shipping
The final stage before your product leaves our factory.
Internal Pre-Shipment Inspection
Our QC team performs a final sampling inspection per ISO 2859-1 (AQL Level II, AQL 2.5/4.0). Checks include:
- Roll weight, width, and length verification
- Visual inspection for coating uniformity, color consistency, selvage quality
- Mesh count spot check
- Packaging integrity
- Label accuracy
- Moisture protection (plastic inner lining if required)
Third-Party Inspection
We welcome third-party inspections by SGS, Bureau Veritas, Intertek, or your own QC team. Simply coordinate the timing with us during order confirmation, and we will have the full lot ready for sampling.
Shipping Documentation
After the container is loaded, you receive the following documents:
- Commercial Invoice — Unit price, total value, trade terms
- Packing List — Roll-by-roll breakdown: each roll’s net weight, width, length, and total pallet count
- Bill of Lading (B/L) or Air Waybill
- Certificate of Origin (if required)
- Inspection Report — Internal or third-party inspection results
- Certificate of Analysis — For special requirements (e.g., REACH, RoHS compliance)
All documents are provided in digital format (PDF) before the vessel departs, with hard copies included in the shipment or couriered separately as required.
7. Common OEM Mistakes and How to Avoid Them
Based on our experience working with dozens of OEM partners, here are the most common issues B2B buyers encounter — and how to prevent them:
| Mistake | Consequence | How to Avoid |
|---|---|---|
| Vague specifications (“standard quality, standard mesh”) | Received product does not meet expectations; no recourse | Write down every parameter in writing. Use numbers, not adjectives. |
| Skipping sample approval | Mass production starts with the wrong specification; costly rework or rejection | Always require and sign off on a production-level sample before mass production. |
| Not specifying packaging in detail | Labels wrong, rolls damaged, pallets incompatible with your warehouse | Provide packaging spec sheet with photos or a reference. |
| Not discussing MOQ flexibility | Stuck with high per-SKU MOQs across many variants | Ask about mixed-container MOQ — combine different SKUs in one container. |
| Assuming all manufacturers test the same way | Quality inconsistency across shipments | Ask for their QC checklist and testing frequency before ordering. |
| No retention sample kept | Hard to compare future shipments against the first approved sample | Keep a signed golden sample and retention labels from each production batch. |
