Quality control
How quality is controlled
Quality control runs at seven points between material receipt and documentation handover, with the purpose of catching each class of defect at the stage where it can still be corrected cheaply. The two stages that matter most in practice are material verification, because grade substitution is invisible at delivery and expensive to discover later, and pre-shipment inspection, because it is the last point at which a discrepancy can be fixed without freight in both directions.
Material verification
Stainless steel is verified by grade on receipt, and material certificates are retained against the production batch.
Why it matters: The most consequential substitution in playground equipment is grade 304 supplied against a grade 316 order. It is invisible at delivery, appears as pitting one to two years later near coastlines, and cannot be corrected without replacing the affected components.
In-process inspection
Dimensional checks against drawings at each fabrication stage, before components are assembled or finished.
Why it matters: A dimensional error found after surface finishing costs the finishing as well as the component. Checking before finishing is what keeps rework contained.
Weld inspection and treatment
Weld seams are inspected, ground and passivated, with particular attention to the flume and to load-bearing joints.
Why it matters: Corrosion in stainless equipment starts at untreated or inadequately ground weld zones, not on the parent sheet. This is also where the structural integrity of a slide or frame is actually determined.
Surface finish check
Flume surfaces checked for finish consistency and for defects that would affect slide friction or present a sharp edge.
Why it matters: The surface finish, not the alloy grade, is what determines how a slide performs. An inconsistent finish produces a slide that is fast in one section and slow in another.
Pre-assembly fit check
Structures are trial-assembled before packing to confirm that components, connectors and fixings match.
Why it matters: A missing or mismatched connector discovered on site costs weeks of shipping time to resolve. Discovering it in the factory costs an hour.
Pre-shipment inspection
Final inspection against the packing list and the agreed specification before the container is sealed, with photographic records.
Why it matters: This is the point at which a discrepancy can still be corrected cheaply. After the container leaves, every correction involves freight in both directions.
Documentation handover
Installation drawings, component lists, maintenance instructions and the applicable certification documentation are issued with the shipment.
Why it matters: Without installation drawings the installer improvises, and an improvised installation of compliant equipment is not a compliant installation. This documentation is also what the buyer needs to satisfy an insurer or a municipal authority.
Third-party inspection
Buyers are welcome to arrange independent inspection before shipment, and we recommend it for first orders. Where a third-party inspection is commissioned, agree the acceptance criteria and the remedy if the goods fail before production begins, rather than after — that is the point at which the inspection has leverage.
