Incoming steel
Steel inspection records support material control before production.
JIASHAN ZHIDAMotorcycle & Automotive Workshop EquipmentQuality controls cover materials, welding, dimensions, load performance, drive systems, coating and packaging. Buyers may appoint third-party inspectors or send their own QC personnel.

Where serial numbers are included on the OEM label, they can trace the production batch. A confirmed PI also allows the factory to identify the corresponding batch.
Inspection records are normally retained for at least three years and may remain available longer according to document-storage conditions.
Discuss an inspection planExact inspection items and acceptance criteria remain model-specific and can be adjusted to customer requirements.
Steel inspection records support material control before production.
Work instructions, visual inspection and penetration checks support higher-requirement welding.
First-piece and patrol inspection against drawings, supported by dedicated gauges where suitable.
100% rated-load testing, batch overload sampling and safety-lock checks according to product requirements.
Hydraulic, pneumatic and electric systems receive assembly, sealing, operating and pressure-hold tests.
Coating cross-cut checks, stacking tests and specified drop tests support shipment readiness.
Records are connected to the applicable PI or serial-number system. Inspection scope remains product- and customer-specific.
Quality documents are matched to the product and project rather than placed in a generic public download folder. Joanna can provide the applicable package after the buyer, company and requested model have been confirmed.
Request quality documentsSteel inspection reports and applicable incoming-material records.
First-piece, patrol and model-specific process inspection records.
Rated-load, sampled overload, safety-lock and drive-system test records as applicable.
Applicable certificates and reports from SGS, TÜV, CCQS or other project-relevant bodies.
Buyers may appoint an independent inspection company or send their own quality-control personnel. Because workshop equipment is highly product-specific, many established customers prefer their own QC teams.
Inspection standards, sampling scope and timing should be agreed before shipment so the relevant records and products are ready for review.
Core products are commonly tested through SGS, with additional certification and testing support from organizations including TÜV and CCQS depending on the product and project.
Calculated from the bill of lading date, subject to correct use and exclusion of misuse, overload and unauthorized modification.
These systems contain wear components. Free replacement parts and technical guidance are included under the stated service conditions.
Replacement parts can travel with container orders or be delivered within China. International express cost is not included in the standard quotation.
Model-specific requirements and documents are confirmed during quotation and order review.
Applicable lifting products receive a 100% rated-load test. Overload testing is performed by batch sampling according to the applicable CE requirement, ASME PASE reference or an agreed customer requirement.
Systems containing wear or sealing components pass at least two control stages, including assembly sealing checks and whole-system operation, pressure-hold or life testing as applicable to the model.
Yes. ZHIDA accepts inspection by an appointed third party, and buyers may also send their own QC personnel. The inspection plan should be agreed before the shipment schedule is finalized.
Yes. OEM products do not need to carry the factory brand. A serial number can be incorporated into the buyer label, and a confirmed PI can also identify the corresponding production batch.
Inspection records are normally retained for at least three years and may remain available longer depending on document-storage conditions.
No. Applicable documents are supplied by Joanna after the buyer, company and relevant product or project have been confirmed. This helps ensure that the correct current document is provided.
