Quality Inspection For Steel Shot & Grit

Steel shot and steel grit are widely used for surface preparation, descaling and shot-blasting in foundries, shipyards, steel-structure and automotive component industries. Stable and reliable quality must be guaranteed before goods leave the factory for overseas destinations.

How many verification steps does one batch of steel shot and steel grit go through before shipment?

Recently, a customer representative visited the SEPPE production base for on-site inspection and loading supervision of this export order. Every step was witnessed and verified item-by-item, including random sampling, package weighing, laboratory testing for grain size, hardness and metallographic structure, as well as container inspection and loading confirmation.

Under the witness of the customer representative, our team followed agreed inspection procedures to take random samples from the ready-to-ship batch. Key indicators including product appearance, grain-size distribution, hardness and metallographic structure were tested.

Test data was confirmed on-site upon completion to ensure bulk products satisfy the technical requirements stated in the order.

Beyond product performance, packaging and loading form critical parts of the inspection process. Our staff conducted random weighing of finished packages, cross-checking product model, packaging specifications, net weight and marking details. Prior to loading, container interiors were inspected to confirm they were clean, dry and suitable for cargo stowage. Goods were then loaded systematically in line with the established stowage plan.

For industrial abrasives, true stability means consistent performance across different batches. True reliability lies in full-process control covering production, testing and final delivery. We systematically eliminate uncertainties before container loading, so both product quality and shipment status are fully verifiable and well-documented.
