04 The manufacturing process

Precision from
ore to bar.

S / 04

Twelve stages from iron ore to dispatch — melting, refining, continuous casting, hot rolling and thermo-mechanical treatment, each with controls of its own.

01From ore to reinforcement

Every stage leaves
a signature.

The final bar is shaped by a chain of linked controls. Stability at one stage protects performance at the next.

Our manufacturing approach pays attention to material condition, rolling temperature, rib formation, water-box behaviour, cooling uniformity and final product verification before release.

Stena Steel TMT manufacturing flow chart with twelve stages: iron ore, sponge iron, melting process in induction furnace, ladle refining furnace, in-process quality check and quality control with process addition, molten metal to continuous billet caster, hot billet charging roughing mill, hot rolling TMT process, thermo mechanical treatment by quenching and self tempering, sampling and testing of TMT bars, third party inspection by SGS, and finished Stena Steel TMT bars ready for supply.

Performance must be
demonstrated.

Quality review combines material, mechanical and dimensional checks to build a more complete picture of the finished bar.

01 / MATERIAL

Chemical composition

Composition review supports stable processing and expected mechanical behaviour.

02 / STRENGTH

Tensile properties

Yield and ultimate tensile response are assessed for the applicable product requirement.

03 / DUCTILITY

Elongation & bend

Elongation, bend and rebend behaviour help evaluate fabrication and structural suitability.

04 / GEOMETRY

Mass & dimensions

Diameter, weight and rib-related consistency support predictable use on site.

Traceability

Know the batch.
Follow the bar.

01Heat or batch identification

02Inspection documentation

03Bundle and dispatch coordination

04Process discipline
PEOPLE

Operators who watch the line

Equipment matters, but attentive process ownership turns settings into repeatable outcomes.

CONTROL

Parameters that stay visible

Critical production conditions are followed so variation can be recognised and managed.

RELEASE

Material that earns dispatch

Final release follows the required checks and order identification workflow.
