ISO 9001:2015 Certified Quality Management System
Reliance Metalcenter is an ISO 9001:2015 certified company with procedures in place to ensure consistency in everything from material inspection to final shipment. Our ISO 9001:2015 certified quality management system applies to both aluminum and steel products, giving customers confidence in our role as ISO 9001:2015 steel distributors and ISO 9001:2015 aluminum distributors.
With over 165,000 square feet of space in our Union City facility, we house an extensive stock of metals that meet documented quality requirements. Material certifications, traceable batch records, and calibrated processing equipment are all standard parts of our workflow. For customers working under AS9100 or other regulated standards, our team provides supporting documentation and certified processing, allowing seamless integration with your supply chain requirements.
Our operation as a metals supply company for the Bay Area is supported by a centralized inventory management system that reduces lead times, supports efficient picking, and minimizes order fulfillment errors. Whether you’re sourcing for a semiconductor tool manufacturer, medical equipment supplier, or aerospace component producer, Reliance Metalcenter maintains the systems necessary for compliant, high-quality delivery.
DFARS and DRC Conflict-Free Materials
In addition to ISO standards, our quality protocols ensure we can meet critical compliance frameworks. We offer DFARS-compliant materials, including DFARS-compliant carbon steel, DFARS-compliant stainless steel, and DFARS-compliant aluminum, for customers working in aerospace, defense, and other federal sectors.
These materials are sourced from approved mills and suppliers that conform to country-of-origin requirements. Our team regularly addresses compliance questions, including:
- Does aluminum need to be DFARS compliant? In certain aerospace and government projects, yes. We stock DFARS-compliant aluminum and can provide certifications upon request.
- Does DFARS apply to carbon steel? Yes, in many defense-related applications, DFARS applies. Our DFARS-compliant carbon steel is sourced from authorized mills and stocked with relevant certification.
We also maintain a certified inventory of DRC conflict-free materials to support customers involved in electronics, communications, and semiconductor fabrication. All documentation can be provided upon request for audit and regulatory reviews.
Just-in-Time (JIT) Inventory Management for California Manufacturers
Our operation is structured around the Just-in-Time (JIT) inventory model. As a steel service center and metal services company serving northern California, we recognize the time-sensitive demands of modern manufacturing.
