Quality, Compliance, and Confidence in Every Meter and Every Ton

In the GCC’s rapidly expanding construction and infrastructure sectors, testing of steel and plastic materials is more than a regulatory requirement — it’s a commitment to safety, sustainability, and structural integrity. At METS Lab, we provide ISO/IEC 17025-accredited testing for steel, plastics, and composite materials, ensuring compliance with Qatar Construction Specifications (QCS), GSO, and international standards such as ASTM, BS EN, and ISO.

Whether you are a contractor, consultant, or manufacturer, working with an accredited testing partner like METS ensures that your materials not only meet design specifications — they exceed expectations for safety, performance, and regulatory approval.

1. Testing Infrastructure and Accreditation

METS operates across the GCC through a multi-national network of accredited laboratories, each specialized in local regulatory frameworks and standards compliance.

Our Accreditation Highlights:

• ISO/IEC 17025 accreditation for testing and calibration.


• QGOSM (Qatar General Organization for Standardization) and ASHGHAL (Qatar Public Works Authority) recognition.


• Collaboration with SABER (Saudi Arabia) and ESMA (UAE)-approved testing programs.


• Authorized to conduct initial qualification (type testing) and routine batch testing for ongoing quality verification.

Every branch under METS ensures continuous conformity with national construction codes and international testing benchmarks, delivering traceable, validated, and audit-ready results.

2. Ensuring Quality and Safety — The Role of Plastic and Steel Testing

In the Gulf’s construction ecosystem, where climate extremes and rapid development intersect, material reliability is fundamental.

Steel and plastics form the structural backbone of modern infrastructure — from high-rise towers and bridges to underground piping and smart city installations.

Why Testing Matters

Rigorous testing of materials ensures that they:

• Meet mechanical, chemical, and dimensional standards.


• Comply with GCC, QCS, and international codes (ASTM, BS EN, ISO).


• Maintain traceability from manufacturing source to on-site delivery.


• Offer long-term safety and durability in harsh Gulf conditions.

In essence, QCS/GSO testing standards convert material “quality” from an assumption into certified proof of compliance and reliability.

3. Steel Testing — Building Strength with Science

Steel is the most critical component in the GCC’s reinforced concrete and structural frameworks.

Under QCS 2024 and GSO regulations, all reinforcement and structural steels must undergo type approval, batch verification, and third-party certification through an ISO 17025-accredited laboratory.

Key Tests for Steel Materials

Compliance Framework

• QCS 2024 – Section 5: Structural and Reinforcement Steel
• BS EN 10002-1, BS EN 15630, ASTM A370 – Mechanical testing
• ISO/IEC 17025 – Laboratory accreditation standard

Under QCS, the Engineer or Authority reserves the right to inspect and re-test materials both at the manufacturing site and upon project delivery.

4. Plastic Testing — Ensuring Performance in Harsh Environments

Plastics are widely used across pipes, conduits, fittings, membranes, and formworks, offering flexibility and corrosion resistance. However, under Gulf climatic stress, compliance and performance validation are mandatory.

Essential Tests for Plastic Products

Regulatory & Environmental Compliance

• QCS 2024 Section 8: Plastics, Pipes, and Fittings


• GSO 2758:2024: Plastic Moulds for Concrete


• ASTM D1785, BS EN 1452, ISO 2507 – PVC, PE, PP systems


• ISO/IEC 17025: Laboratory competence


• Environmental Directive: Prohibits use of lead stabilizers and restricted additives

These standards ensure that all plastic materials are fit for Gulf environments, resistant to high temperature and pressure, and compliant with health and environmental regulations.

5. GCC Testing Ecosystem and Cross-Border Compliance

METS supports clients across the Gulf through harmonized multi-country testing and certification, providing a unified compliance solution for regional markets.

METS laboratories across the GCC ensure cross-recognition of test reports, helping clients achieve multi-market certification efficiently.
