What is your minimum order quantity (MOQ)?

Yes. Every finished conduit goes through dimensional accuracy testing (outer diameter, wall thickness, and ovality), thread gauge inspection (for threaded ends), coating thickness measurement and salt spray testing (for corrosion resistance), mechanical strength testing (compression load and bend cycle), and visual inspection (for surface scratches, dents, and plating uniformity). Every shipment comes with a detailed test report, including batch traceability.

Our craftsmanship standards are reflected in every detail:

Wall thickness consistency — Tolerance is controlled within ±0.05mm across the entire length, ensuring uniform mechanical strength and seamless joint compatibility.

Inner surface finish — Bore roughness is maintained to a strict low-level standard, preventing insulation abrasion during cable pulling and reducing friction loss.

Thread precision — All threaded ends are machined to ANSI/UL standards, with gauge-fit accuracy within one full turn, ensuring leaktight connections and reliable grounding.

Coating & corrosion resistance — Only our inline emt conduits deliver a dense, uniform zinc coating with superior adhesion, providing exceptional corrosion protection that passes rigorous salt spray testing with no red rust. This process is unique to our steel conduit production and ensures long-term durability in harsh environments.

We believe great craftsmanship isn't something we advertise — it's something we prove in every millimeter, every thread, and every test report we deliver.

We believe the electrical conduit market — driven by infrastructure modernization, stricter fire safety regulations, and the growing adoption of sustainable materials — remains robust and steadily growing.

Yes. We conduct quality inspections before shipment to ensure that products meet the agreed specifications and quality requirements. Inspection reports and relevant quality documentation can also be provided upon request, depending on the product and order requirements.
