Custom Outdoor Sofa Seat Support Wire Grid
Zhengna Technology supports outdoor sofa seat support wire grids made completely to the buyer's controlled drawing. The photograph on this page is a representative sample. It shows one possible wire-grid form, but it does not define the dimensions, material, finish, load, durability or approval requirements for another project.
A useful quotation starts with the drawing, overall dimensions, material, surface treatment, quantity and use environment. Those inputs determine whether the geometry needs several forming or assembly steps, which in turn affects tooling, production planning and price.
Send the controlled drawing and quotation requirements
Reference configuration and commercial terms
The following price is a real obtainable quotation reference for the stated configuration and minimum quantity. It is not a universal price for every drawing or outdoor seating project.
| Item | Confirmed reference |
|---|---|
| Product scope | Fully made to the customer's controlled drawing |
| Reference material | Carbon steel with PVC tubing |
| Reference wire diameter | 1.2 mm |
| Approximate reference size | 40 cm by 40 cm |
| Reference surface treatment | None |
| Reference unit price | USD 0.40 per piece |
| Minimum order quantity | 1,000 pieces |
| Reference trade term | FOB Ningbo or Shanghai |
| Supply status | Preorder production |
| Typical production lead time | Approximately 30 days after the drawing, commercial terms and production conditions are confirmed |
The USD 0.40 reference applies only to the carbon-steel and PVC-tubing configuration above at 1,000 pieces. A different size, wire diameter, material, finish, geometry, process sequence, quantity, packaging or inspection requirement requires quotation confirmation.
Applicable China-side taxes and export charges are included in the reference quotation. International freight is not included in the FOB reference. When CIF is requested, freight is included only in the separately confirmed CIF quotation. Import duties and destination-country taxes remain the buyer's responsibility. EXW, FOB and CIF quotations are supported.
The commercial record uses August 10, 2026 as its reference date and a three-year review horizon. This is not an unconditional fixed-price promise: a material, exchange-rate or specification change requires the quotation to be reconfirmed before order placement.
Mold and tooling reference
For this made-to-drawing product family, both a mold and production tooling are normally required. Typical references are approximately USD 500 for the mold and USD 300 for tooling. These charges are separate from the USD 0.40 unit price and are confirmed after drawing review.
The principal price driver is not only the outside size. A geometry that needs several forming, positioning, joining or handling stages can require a different tool concept and production route. The quotation should therefore identify the controlled drawing revision, process assumptions, sample plan and ownership of later design changes.
What the buyer should send for quotation
- the controlled drawing, revision, units and file precedence;
- overall dimensions, wire diameter, bend geometry, hooks, interfaces and tolerances;
- material and material-authority requirements;
- surface treatment or confirmation that none is required;
- prototype, order and forecast quantities;
- the outdoor use environment and any humidity, splash, temperature, cleaning or corrosion requirements;
- critical dimensions, inspection frequency, reports and acceptance criteria;
- packaging, labeling, delivery term, destination and requested timing.
A photograph can help explain the overall concept, but it cannot replace the controlled drawing. Hidden interfaces, free-state geometry, installed position, cushion interaction and acceptance limits must be defined by the responsible design owner.
Inspection and release planning
A 2D optical measuring system is used for applicable drawing-defined characteristics. Depending on the agreed control plan, the project can combine first-article inspection, sampling inspection, per-batch verification and 100% inspection of specifically designated characteristics.
This combination does not mean that every characteristic on every part is automatically inspected 100%. The drawing and control plan should name the characteristic, equipment or method, frequency, record, acceptance rule and reaction plan. Finished-seat comfort, load, fatigue, weather resistance and safety remain system-level responsibilities unless an exact component or subassembly test is separately defined and approved.
Useful first-piece evidence may include the measured dimensions agreed for release, the drawing revision, measurement method and sample identity. Production evidence should remain linked to the relevant lot and revision where the contract requires traceability.
Packaging and production timing
The confirmed packaging method is to nest or stack the parts and then secure them on a wooden pallet. The final packing plan should control deformation, hook or edge damage, surface contact, pallet stability, moisture exposure, labels and mixed-revision prevention.
Supply is scheduled as preorder production rather than unrestricted shelf stock. Typical production lead time is approximately 30 days after the drawing, tooling, quantity, inspection scope, packaging and commercial terms are confirmed. A new tool, drawing change, additional validation or unusual packing requirement can change the schedule.
Customer project feedback
Average product feedback: 4.5/5 based on five customer project follow-ups collected in 2025. The source records are retained.
“This supplier offered pricing in line with the industry, responded quickly and provided strong service follow-up.”
— Fusai, June 1, 2025 · 4.6/5
The feedback applies to this outdoor sofa seat support wire-grid product scope and the recorded project experience. It does not establish a universal price advantage, response-time guarantee, defect rate, delivery result, performance approval or outcome for another drawing.
From component drawing to finished-seat approval
The wire grid functions inside a larger seating system. The buyer should identify the frame opening, cushion stack, support zones, load introduction points, hooks or connection interfaces, nearby hardware and installed orientation. A component can match its drawing while the complete seat still requires separate comfort, durability, stability, upholstery, weather and safety validation.
- Drawing review: align revision, geometry, material, surface requirement, interfaces and open assumptions.
- Tooling review: confirm the mold, tooling concept, process sequence and sample timing.
- First-piece review: inspect the designated characteristics using the agreed method and record.
- Buyer validation: evaluate fit, assembly and any defined component, subassembly or finished-seat tests.
- Production release: retain the approved revision, control plan, packaging method and authorized deviations.

Frequently asked questions
What does the USD 0.40 price cover?
It is a reference FOB Ningbo or Shanghai price per piece at a minimum order quantity of 1,000 pieces for the stated carbon-steel and PVC-tubing configuration with 1.2 mm wire, an approximate 40 cm by 40 cm size and no surface treatment. Mold, tooling, international freight, import duties and destination-country taxes are separate.
Are the mold and tooling included in the unit price?
No. Both are normally required for this product family. Typical references are approximately USD 500 for the mold and USD 300 for tooling, subject to the controlled drawing and production route.
How are dimensions inspected?
A 2D optical measuring system is used for applicable drawing-defined characteristics. First-article, sampling, per-batch and characteristic-specific 100% inspection can be combined according to the agreed control plan.
Is the photograph the exact product for every quotation?
No. It is a representative sample. Every quotation and production release is based on the current buyer drawing, material, dimensions, finish, quantity, environment and acceptance requirements.
How long does production take?
Typical production lead time is approximately 30 days after the drawing, tooling, quantity, inspection plan, packaging and commercial conditions are confirmed. The final schedule is stated in the quotation or order confirmation.
