SASO Steel Standards: Saudi Arabia Conformity Requirements for Structural & Rebar Steel

Quick Answer

SASO — the Saudi Standards, Metrology and Quality Organization — is the national body responsible for issuing Saudi Standards (SS), operating the national metrology system, and enforcing conformity requirements on regulated products entering the Saudi market. For steel used in construction, SASO standards are mandatory, not voluntary, and customs clearance at Saudi ports requires documentary evidence of conformity.

Saudi Arabia adopts many international standards by direct reference or with minor modifications. Most SASO steel standards are technically equivalent to ASTM International or ISO specifications, giving international mills a clear path to compliance without redesigning product.

Scope and Applicability

SASO steel standards apply to:

• Reinforcing steel bars (rebar) for reinforced concrete construction
• Structural steel sections (beams, columns, angles, plates) used in buildings and infrastructure
• Steel hollow sections for structural applications
• Steel products supplied to government-funded projects, which must comply with Saudi Building Code (SBC) references

Private projects may specify alternative standards, but the SALEEM mark is required for imported products classified as regulated construction materials regardless of project type.

Standards Adoption Framework

Saudi Arabia adopts international standards through two mechanisms:

1. Direct adoption as Saudi Standard (SS): The international standard is republished as an SS number with little or no technical change. SASO 203 adopts ASTM A615 Grade 420 and Grade 520 with identical composition and mechanical limits.

2. Adoption by reference: Saudi Building Code sections reference international standards (ACI 318, AISC 360, BS 5950) directly, meaning material supply to SBC-governed projects must meet those referenced standards even when no separate SS exists.

The GCC Gulf Standards Organization (GSO) layer adds a further tier: GSO standards are collectively adopted by all GCC member states including Saudi Arabia. Where a GSO standard exists for a product category, Saudi Arabia implements it as the applicable SS.

Grade Coverage

SASO 203 — Steel Bars for Concrete Reinforcement

SASO 203 is the primary rebar standard for Saudi Arabia. It covers deformed and plain bars for reinforced and prestressed concrete.

These limits are identical to ASTM A615/A615M. Grade 420 (the equivalent of ASTM Grade 60) is the dominant specification on Saudi construction projects.

SASO 2178 — Hot-Rolled Structural Steel Sections

SASO 2178 covers hot-rolled I-beams, H-sections, channels, and angles for structural applications. The standard references EN 10025 grade designations (S235, S275, S355) as the technical baseline for chemical and mechanical requirements.

Chemical Composition Requirements

SASO 203 Rebar — Chemical Limits (wt%)

Carbon equivalent is calculated as: CEV = C + Mn/6 + (Cr+Mo+V)/5 + (Ni+Cu)/15

Note: These limits match ASTM A615-22 limits. For epoxy-coated or galvanized bar, additional restrictions on phosphorus may apply per project specification.

Mechanical Properties

SASO 203 — Tensile Test Requirements

Bend test: Bars must withstand 180° bend around a pin diameter of 3.5× bar diameter (Grade 420) without cracking on the outer surface.

Rebend test is not mandated by SASO 203 but may be invoked by the project specification for seismic zones.

Mandatory Certification Requirements

SALEEM Conformity Mark

The SALEEM mark (also written SABER under the updated Saudi Product Safety Program) is the mandatory conformity mark for regulated products entering the Saudi market. For construction steel:

1. Product Registration: The product type and grade must be registered in the SABER platform (saber.sa) by an accredited Conformity Assessment Body (CAB).
2. Third-Party Testing: A SASO-recognized or internationally accredited laboratory must test representative samples against the applicable SS.
3. Factory Assessment: The manufacturing facility must pass an initial factory inspection and periodic surveillance audits.
4. Certificate Issuance: The CAB issues a Product Certificate of Conformity (CoC) linked to the SABER registration.
5. Shipment Certificate: Each shipment must be accompanied by a Shipment Certificate of Conformity (SCoC) cross-referencing the Product CoC.

Customs authorities verify the SCoC number against the SABER database at the port of entry. Shipments without a valid SCoC are held or returned.

Accredited Certification Bodies (CABs) for Saudi Steel

Major internationally recognized CABs active in Saudi Arabia include Bureau Veritas, SGS, Intertek, TÜV Rheinland, and RINA. Each must hold SASO recognition for the specific product category.

Cross-Standard Equivalents

For mills holding ASTM A615 or EN 10025 certification, achieving SASO conformity requires primarily the SALEEM/SABER registration process rather than product reformulation.

Saudi Aramco Supplementary Requirements

Steel used on Saudi Aramco projects (upstream oil and gas, petrochemical, downstream) is subject to Saudi Aramco Materials System Specifications (SAMSS) in addition to SASO requirements. Key supplementary requirements include:

• SAMSS-031: Structural steel for offshore and onshore facilities — imposes Charpy impact testing at −20 °C not required by SASO 2178.
• Third Witness Inspection (TWI): Saudi Aramco Inspection Department or their designated representative must witness mill testing. The MTC must include the TWI representative's stamp.
• Heat Traceability: Full heat-to-heat traceability from billet/bloom to finished product. Bundle-level tracking with heat number stenciling is mandatory.
• PMI (Positive Material Identification): Required for alloy steel grades used in pressure-containing components.
• Document Language: All certificates must be in English. Arabic translation is not accepted in lieu of English originals for Aramco projects.

MTC Verification Checklist

What Middle East buyers and Saudi customs agents check on a mill test certificate for SASO-governed steel:

• SASO standard number and edition cited (e.g., "SASO 203:2006" or equivalent)
• Grade designation matches purchase order (Grade 420 or Grade 520)
• Heat number printed on certificate matches markings on bundles
• Chemical analysis results within SASO 203 limits for all elements (C, Mn, P, S, CEV)
• Tensile test results: yield strength, tensile strength, elongation — all meeting minimums
• Bend test result: pass/no crack stated
• Mill name, location, and authorized signatory with stamp
• SALEEM/SABER SCoC certificate number linked to shipment
• Lot identification: heat number, rolling date, bar size, quantity (tonnes/pieces)
• For Aramco projects: TWI stamp, impact test results, PMI report number
