Automated continuous extrusion lines achieve tighter wall-thickness tolerances (±0.05 mm) and high melt homogeneity, producing over 10 million tons of industrial material across our corporate group annually.
Port Proximity & Mixed Loadings
Direct proximity to Tianjin Port allows single-manifest consolidation: combining PVC cable raceways, conduit pipes, structural H-beams, and channel supports in single containers to slash procurement logistics costs.
International Regulatory Compliance & Material Testing
Every batch produced under ISO protocols undergoes physical, electrical, and flammability verification prior to global dispatch.

Frequently Asked Questions for EPCs & Importers
Direct engineering answers addressing material formulation, tooling customizability, and multi-product shipment consolidation.
What PVC formulations and additives do you utilize for custom industrial cable ducts?
We use virgin suspension PVC resin (K-value 65–67) blended with calcium-zinc non-toxic thermal stabilizers, impact modifiers (CPE/acrylic), calcium carbonate filler for structural stiffness, and rutile TiO2 for UV shielding. Flame retardants are tuned to meet specific UL94 V-0 or British Standards (BS 4678) requirements upon engineer request.
Can you manufacture non-standard profile dimensions and custom slot patterns?
Yes. Our in-house mold and tooling workshop designs custom extrusion dies and automated inline punching tools. Whether your project specifies narrow finger-slots for high-density telecommunication wire wrapping, solid unslotted bottom walls, or asymmetric dual-compartment designs, tooling can be created in 15–20 business days.
Can we consolidate PVC cable ducts with structural steel sections in one shipment?
Absolutely. One of our primary market strengths is complete Bill of Materials (BOM) consolidation. Because HZXY is an established producer and distributor of structural H-beams, angle steel, channel steel, and drainage pipes, overseas contractors can combine metallic framing supports and polymer ducting systems into single ocean containers, saving substantial freight and clearance expenditures.
Where is HZXY located, and which ports handle your export dispatches?
Our core headquarters and main fabrication bases are centered within the Daqiuzhuang Industrial Zone, Jinghai District, Tianjin, with secondary large-scale operations in Tangshan. Most export orders are handled directly via Tianjin Port (Xingang), the premier shipping hub in North China, with secondary port options (Qingdao, Shanghai) arranged upon request.
Do shipments include raw material certificates, and is third-party inspection permitted?
Every dispatch is accompanied by an authoritative Mill Test Certificate (MTC) verifying physical tensile tests, thermal Vicat points, flammability scores, and dimensional conformance. We frequently host independent international quality verification auditors (SGS, TÜV, Bureau Veritas) selected by buyers prior to container sealing.
How can prospective buyers obtain your complete technical catalog and pricing sheet?
You can access complete engineering schedules and dimension charts directly via our Request a Catalog portal or by contacting our specialized technical export engineering desk at [email protected].
