"Game-Changer for Custom Projects." "We had a retrofit project with space constraints needing a uniquely shaped plenum. Jinzehong's engineers worked with our CAD file, delivered perfect prototypes, and then fulfilled the bulk order ahead of schedule. Their ODM capability is a real differentiator." - Michael R., Technical Manager, Engineering Firm, Canada
"Solved Our Inventory Problem." "The fast 18-day turnaround and reliable sea freight schedule have allowed us to reduce our warehouse inventory of standard plenum sizes by 40%. We order more frequently with confidence, freeing up cash flow." - Sarah L., Operations Manager, Ductwork Fabricator, Australia
"Zero Defects, Consistently." "Over the past 12 containers, we've had zero returns for quality issues on their galvanized steel plenums. The seams are tight, the gauge is always as specified, and they pack them securely to prevent shipping damage. It's a reliable, 'set-and-forget' part of our supply chain now." - David K., Purchasing Manager, HVAC Wholesaler, USA
For standard sizes, our MOQ can be as low as 100 pieces. For fully custom ODM designs, the MOQ is typically 500 pieces, but we are flexible and encourage you to discuss your project volume with us for the best pricing.
Absolutely. This is our specialty. Please provide detailed drawings, samples, or specifications (including material grade, gauge, dimensions, connector type, and seam requirement). Our engineering team will confirm feasibility and provide a quote.
Standard terms are 30% T/T deposit with order, 70% balance before shipment. We ship FOB Tianjin/Xingang, CIF to major US ports (LA, Long Beach, NY), or DAP per Incoterms 2020. We handle all export documentation and work with reliable freight partners to ensure smooth logistics.
Yes, we provide samples for quality verification. Standard samples are free; you only pay the shipping cost. For custom ODM samples, a modest tooling/sample fee applies, which is deductible from your first bulk order.
Our QC process is multi-stage: 1) Raw material inspection (verifying MTCs), 2) In-process checks during cutting, bending, and seaming, and 3) Final dimensional and visual inspection before packing. We can also arrange third-party inspections (SGS, BV) upon request.
Limited-Time Offer for New Partners: Submit your inquiry this month and receive free CAD optimization on your first custom design, plus a 5% discount on your initial container (FOB) order.
Risk-Free First Step: Order a sample plenum to verify our quality matches your standards before committing to a bulk order.
