ODM PVC Wire Trunking Factories & Suppliers

HZXY's competitive edge stems from complete raw material control and 30 years of manufacturing scale across Tianjin and Tangshan. We compound virgin PVC resin with proprietary impact modifiers and flame retardants in-house, ensuring batch-to-batch structural integrity that will not crack or turn yellow. Moreover, our industrial base allows global buyers to consolidate PVC wire trunking with structural steel sections, pipes, and electrical fittings in single shipments, drastically reducing overall procurement freight and import administration overhead.

Yes. As a full-service ODM partner, our precision tooling workshop produces extrusion dies, calibration units, and punching molds for customized widths, heights, partition walls, and snap-lock clasp geometries. Once tooling drawings are approved, trial extrusion samples are fabricated, dimensional CMM-verified, and air-couriered to your engineering team within 10 to 14 days.

Our standard trunking models achieve UL 94 Class V-0 flammability ratings, self-extinguishing within 5 seconds without burning drips. We fully comply with the European Union RoHS Directive 2011/65/EU and REACH regulations (eliminating hazardous lead, mercury, cadmium, and toxic plasticizers). For underground mass transit and enclosed server rooms, we formulate Low-Smoke Halogen-Free (LSOH) materials that emit minimal non-corrosive smoke during high-temperature combustion.

PVC trunking is inherently volumetric and low density. If shipped alone, freight containers frequently max out on volume (CBM) while utilizing only a fraction of allowable tonnage, drastically raising unit transport costs. Because HZXY is a major steel manufacturer, we offer innovative multi-product consolidation: nesting smaller trunking sizes inside larger profiles, and packing PVC ducting alongside high-density carbon steel pipes, rebar, or H-beams to reach optimal 28-ton, 68-CBM 40HQ container thresholds.

For standard sizes and catalog colors (White and Grey), our MOQ is typically 3,000 meters per profile size, with stock sizes ready for container dispatch in 7 days. For custom ODM colors, proprietary perforations, or branded protective film packaging, the standard MOQ is 10,000 meters or one 20GP container. Production run fulfillment ranges from 15 to 25 business days from final deposit and sample sign-off.

Absolutely. We actively encourage and regularly host independent quality assurance audits at our Tianjin freight yard and workshops. Third-party testing technicians can conduct on-site wall-gauge measurements, flammability burn checks, drop impact tests, barcode readability audits, and verify container sealing integrity prior to port departure.
