ISO 9001:2015 Quality Management System
For engineering clients, ISO 9001 is not a certificate on the wall — it is the answer to whether a supplier's quality can be audited. Hengsheng's system is audited and issued by SGS, covering the full scope of design, production, sales and service under certificate HK-QMS-0258-2024, valid from 2024 to 2027, and working in tandem with the 68 internal inspection gates.
Core Strengths
- Full-scope certification: covering design, production, sales and service rather than a single workshop, so procedural documents can be requested at any stage from selection and shop drawings to after-sales.
- Independent third-party audit: assessed by SGS with annual surveillance visits; non-conformities must be corrected within a set period and verified as closed.
- Linked to internal practice: the 68 inspection gates, batch traceability and non-conforming product handling are written into the system, so the documents describe what is actually done.
- Usable in tenders and acceptance: certificate copies, scope statements and surveillance records are available for tendering, owner review and supplier prequalification.
Key Figures
Service Process
- System planning: quality policy, objectives and process responsibilities defined.
- Documentation: work instructions, inspection records and traceability rules written into executable form.
- Internal audit: periodic internal audits and management review, with deviations identified and corrections implemented.
- Third-party audit: initial certification and annual surveillance by SGS.
- Continual improvement: complaints, non-conformance data and audit findings drive the next cycle.
Applications
- Supplier prequalification for government and public works tenders
- Vendor assessment by international hotel groups
- Quality system documentation required by main contractors of subcontract materials
- Compliance document lists specified by owners on cross-border projects
Sustainability & Certification
ISO 9001 and ISO 14001 share one process framework, so quality records also feed environmental indicators for energy, wastewater and waste, avoiding two disconnected sets of data.
The system requires root-cause analysis and reduction of non-conforming product and scrap, directly cutting secondary consumption of material and energy, alongside 95% process water recycling and over 85% waste utilisation.
Deep Selection Guide
When checking an ISO 9001 certificate, what matters is not whether it exists but three things: whether the scope covers the stage you are buying, whether the issuing body is accredited, and whether the certificate is still valid with surveillance audits completed. Ask for the certificate copy and scope attachment during prequalification and check that company name and address match; request the most recent surveillance record as well. Where traceability matters, ask for the batch coding rules and sample test reports to confirm the system reaches every shipment rather than only the paperwork.
- Selection criteria：Start from the actual conditions at Supplier prequalification for government and public works tenders, then narrow the options by Full-scope certification; colour is the last layer to consider.
- Specification & thickness：Set panel size and thickness first by Certificate no. (HK-QMS-0258-2024), then thicken or reduce locally for Vendor assessment by international hotel groups, with cut-out positions noted on the same drawing.
- Acceptance & records：Make Independent third-party audit: assessed by SGS with annual surveillance visits; non-conformities must be corrected within a set period and verified as closed. the focus of acceptance, checked and archived before dispatch; accept on site by number, with any dispute traceable to that batch.
- Sustainability：ISO 9001 and ISO 14001 share one process framework, so quality records also feed environmental indicators for energy, wastewater and waste, avoiding two disconnected sets of data. Write it into the acceptance terms and apply the local green building requirements alongside it.
What Hengsheng does with ISO 9001:2015 Quality Management System is join quarry-direct supply, smart manufacturing and global delivery into a single line where every step is documented, so project teams need not rely on judgement alone to weigh risk.
FAQ
- How are validity and surveillance audits arranged?
- The current certificate runs from 2024 to 2027, with SGS surveillance audits each year and recertification at the end of the three-year cycle. Clients may request surveillance records to confirm the certificate remains valid.
- Does the scope include design and after-sales service?
- Yes — the scope is full: design, production, sales and service. System documentation therefore supports selection advice, shop-drawing development and installation guidance, not only the production floor.
