The full material specification, certification and compliance policy, production evidence and manufacturing photo set behind every KAISTEEL unit — consolidated on one page for buyers who need to verify before they commit.

Factory-profile figures and qualifications are supplier-reported. 304 is the standard grade; 316 is available as an order-selected upgrade, not a blanket default — the exact grade supplied is confirmed on the quotation and Technical Freeze Sheet for each order.
Supplier-issued conformity documents may be available for selected component models, including CE documentation and, for Great Britain, UKCA or CE documentation as applicable under current destination requirements. Documents are verified against the actual model, destination market and validity at order confirmation. They do not constitute blanket certification of the complete KAISTEEL system. Controlled copies are provided to qualified buyers on request.
Production is coordinated through an approved manufacturing partner in Foshan, Guangdong, under KAISTEEL's order-specific specification, QC and documentation controls. Supplier history and facility qualifications are verified through controlled due diligence before being used for an order.






For each confirmed production lot or shipment, KAISTEEL compiles an order-specific Compliance Dossier matched to the approved BOM, selected components and destination market.
Include destination market, buyer type, model, quantity and target delivery date for the fastest response.
