Inside the Mejonson Partnership: How Kingmaker Steel Controls Quality from the Mill

The Problem with Inconsistent Imports

Before 2008, like many master distributors, Kingmaker Steel sourced from multiple overseas mills. The result was inconsistent quality — variations in wall thickness, surface finish, and dimensional tolerances that created problems for our distributor customers and their end users. Some shipments were excellent; others required sorting, returns, or customer credits.

The Mejonson Solution

In 2008, after years of working to solve this problem, Kingmaker Steel developed an exclusive partnership with Mejonson International. This partnership gave us direct involvement in the production process — from raw material sourcing through finished tube production.

ISO 9001 & ISO 14001 Certified

Mejonson International operates under both ISO 9001 (quality management) and ISO 14001 (environmental management) certification. These certifications ensure that production processes are documented, controlled, and continuously improved. Every coil of raw material, every production run, and every shipment is traceable.

Consistently Smooth Interior Weld Seam

One of the distinguishing characteristics of tubing produced through the Mejonson partnership is the consistently smooth interior weld seam. Unlike some imported tubing where the internal weld bead is inconsistent or excessive, Mejonson-produced tubing features a controlled weld profile that provides better formability and a cleaner appearance in fabricated assemblies.

What This Means for Distributors

When you purchase from Kingmaker Steel, you are getting tubing from a known, certified source — not a random import broker. The material is consistent from order to order, shipment to shipment. Your customers get predictable quality, and you get fewer returns and complaints.
