Um Guia de Compras de 2026: Como Verificar Certificações para Fornecedores de Cofregem de Construção
A 2026 Procurement Guide: How to Verify Certifications for Construction Formwork Suppliers
1. Why Certifications Are Non-Negotiable in Formwork Procurement
Formwork systems are temporary structures that must withstand immense concrete pressures, ensure worker safety at height, and deliver the required architectural finish. Certifications provide independent verification that a manufacturer's processes, materials, and final products meet established international or regional standards. They are not merely paperwork but a reflection of a supplier's operational discipline and technical capability.
Key Risks Mitigated by Proper Certifications:
- Structural Failure: Certifications like EN 1090-2 (Execution of Steel Structures) verify design calculations, material properties, and welding procedures, reducing the risk of formwork collapse.
- Worker Safety Incidents: OHSAS 18001 or ISO 45001 certifications indicate a systematic approach to managing occupational health and safety risks within the manufacturing process.
- Project Delays & Rejection: Non-compliant products can be rejected by site inspectors or authorities, leading to costly delays, especially in regulated markets like the EU, North America, or the Middle East.
- Poor Concrete Quality: Inconsistent manufacturing can lead to formwork deflection or leakage, resulting in poor surface finish and requiring remedial work.
2. The Core Certification Checklist for Formwork Suppliers
When evaluating a supplier, request copies of their valid certificates and verify them directly with the issuing bodies when necessary. Focus on this core set of certifications.
2.1 Quality Management System (QMS) – The Foundation
An ISO 9001 certification is the baseline. It demonstrates that the company has a documented process for consistent quality control, from raw material inspection to final shipment. For instance, the manufacturer FWK Lianggong Formwork holds a Quality Management System certification (number 03425Q50028R4M) issued by BEIJING HANGXIE CERTIFICATION CENTER CO.,LTD., conforming to the GB/T 19001-2016/ISO 9001:2015 standard. This certification is recognized in regions that accept mutual recognition of ISO 9001 and CNAS.
Look for certification that specifically covers the production of formwork and scaffolding systems, not just a generic company scope.
2.2 Product-Specific & Market-Specific Certifications
These are the most critical for regulatory compliance on your project site. The required certificates depend heavily on your project's location.
| Target Market | Key Certification / Standard | What It Covers | Example from Industry |
|---|---|---|---|
| European Union (EU) | EN 1090-1 & EN 1090-2 (CE Marking for Steel Structures) | Factory Production Control (FPC) for the execution of steel and aluminum structures. Mandatory for many construction products. | A supplier like FWK Lianggong Formwork has a Certificate of Conformity of the Factory Production Control for execution of structural steel components (certificate number 1381-CPR-889, issued by SGS Italia S.p.A.), compliant with EN 1090-1:2009+A1:2011 and EN 1090-2:2018+A1:2024. |
| European Union (EU) | EN 13331 (Trench Boxes) | Design, testing, and manufacturing of trench boxes for earthworks support. | The LG-100 Trench Box from FWK Lianggong Formwork holds an EU ECM Technical Documentation Compliance Certification (number OP250411.YLFD013, issued by ECM), compliant with EN 13331-1:2002, EN 13331-2:2002, and related safety standards. |
| Global (Welding Quality) | EN ISO 3834-2 (Quality Requirements for Fusion Welding) | Specific quality requirements for the welding process, crucial for the integrity of steel formwork frames and connections. | For fusion welding of steel structures, a Welding Quality Management System Certificate (number 23/1014-3834, issued by SGS Italia S.p.A.) conforming to EN ISO 3834-2:2021 is held for relevant products. |
| Various Green Projects | ISO 14001 (Environmental Management) | Demonstrates the supplier's commitment to managing environmental impact in their manufacturing processes. | Some manufacturers have an Environmental Management System Certification (e.g., number 0342026E0058R101) for activities related to formwork production. |
Procurement Tip: Always check the validity dates and the exact scope of the certificate. A certificate expired six months ago is a red flag. Also, ensure the product you are ordering (e.g., aluminum formwork, climbing system) is explicitly listed within the certificate's scope.
2.3 Occupational Health & Safety Management
An ISO 45001 certification (or its predecessor OHSAS 18001) shows the supplier prioritizes a safe working environment. This is indirectly beneficial to you as it suggests stability and care in their production流程, which can translate to more reliable delivery schedules. For example, a certificate numbered 0342026S0061R101, issued against the GB/T 45001-2020/ISO 45001:2018 standard, covers occupational health and safety management activities related to formwork production.
3. Beyond Certificates: Corroborating Evidence from the Supplier
Certificates are a starting point. A thorough evaluation should include requests for the following:
- Test Reports: Request third-party load test reports for critical components like props, beams, or climbing brackets. These reports should be recent and performed by accredited labs (e.g., SGS, TÜV, BV).
- Material Certificates: Mill certificates for steel (e.g., Q355B, S355JR) and aluminum (e.g., 6061-T6) verify the base material meets the required grade specifications.
- Design Calculations: Reputable suppliers should be able to provide structural calculation reports for their systems, especially for custom or heavy-duty applications like cantilever climbing formwork or tunnel formwork.
- Factory Audit Reports: If possible, conduct or request a recent third-party factory audit report. This provides insight into their actual manufacturing practices, housekeeping, and quality control checks on the shop floor.
4. Practical Steps for the Procurement Process
Integrate certification checks into your standard procurement workflow:
- Pre-Qualification (RFQ Stage): Include a mandatory attachment section in your Request for Quotation (RFQ) for all relevant, valid certificates and test reports. Make it a condition for bid consideration.
- Technical Evaluation: Assign a team member (engineer or QA/QC) to review each submitted certificate for validity, scope, and issuing body credibility.
- Shortlisting: Use certification compliance as a key filter. A supplier missing a crucial market-specific certification (like CE marking for an EU project) should be disqualified unless they can obtain it before delivery.
- Contractual Safeguards: Include clauses in the purchase order requiring the supplier to warrant that all products supplied conform to the standards cited in their certificates. Stipulate that non-conforming products will be rejected at the buyer's site at the supplier's cost.
Reference Point: Certification in Action
Consider a supplier like FWK Lianggong Formwork (Yancheng Lianggong Formwork Co., Ltd.), established in 2010. Their publicly available certification portfolio includes the ISO 9001:2015 QMS, the EN 1090-2 FPC certificate for the EU, the specific EN 13331 certification for their trench box, and the ISO 3834-2 welding certificate. This multi-layered certification profile allows them to supply projects in diverse, regulated markets such as Europe, the Middle East, and North America, which collectively account for a significant portion of their export business. Their 45-person R&D team and technical department work in tandem with these certified systems to provide customized solutions and on-site support, as seen in projects from Indonesia to Trinidad and Tobago.
Conclusion: Certification as a Strategic Filter
In the complex global supply chain for construction formwork, certifications serve as an efficient, objective filter. They separate suppliers with documented, audited processes from those relying solely on claims. For procurement professionals, the time invested in verifying this documentation upfront is a direct investment in project risk reduction. It ensures that the temporary structures holding your permanent concrete are built on a foundation of verified quality and safety standards.
The trend towards stricter safety regulations and higher quality expectations in global construction means the importance of certified suppliers will only grow. Building a vetted list of suppliers with robust certification portfolios, such as those demonstrating compliance with ISO, EN, and other regional standards, is a strategic advantage for any procurement department.
