FOUNDATION
Why Steel Standards Matter
Steel products in industrial projects must meet 
strict quality standards. ASTM and ASME 
certifications ensure consistency, safety, and 
reliability across global supply chains.
Without proper certifications, projects face 
rejection, structural failure, and legal 
complications. Understanding these standards 
protects investment and ensures long-term 
performance.

ASME
What Are ASME Standards?
Design Codes Safety Focus Critical Industries
ASME focuses on design codes and safety Ensures systems operate safely under Essential for oil and gas, petrochemical, and 
regulations for pressurized systems. pressure and high temperatures. power generation sectors.
Key ASME Codes
ASME Section II • ASME Boiler and Pressure Vessel Code (BPVC)
• ASME B16.5 flange standard
Adopts ASTM specifications with "SA" prefix (e.g., ASTM A240 • ASME B31.3 process piping code
becomes ASME SA240)
ASME certification guarantees safety in pressurized systems and is 
required by international EPC contractors.

CERTIFICATION
Mill Test Certificates & 
Compliance

MTC Verification Type 3.1 Certification
Mill Test Certificate confirms steel meets Manufacturer testing confirmation per 
required standards with chemical EN 10204 standards

03
Type 3.2 Certification
Includes third-party inspection verification for enhanced quality assurance
Without proper MTC documentation, materials face rejection during quality audits, 
causing project delays and financial loss.
