Full In-House Control

Our Production Process

From raw material to finished product -- every step is performed in-house with precision equipment, ensuring consistent quality at every stage.

Shot Blasting / Peeling Machine

Removes surface oxidation and defects from the steel, ensuring a clean and smooth surface for further processing. This critical first step guarantees optimal adhesion for subsequent treatments.

Surface Prep Oxide Removal

Shot Blasting and Peeling Machine for steel surface preparation

Pointing Machine

Reduces the diameter at the ends of the bars to prepare them for the cold drawing process. Precise pointing ensures smooth entry into the drawing die, preventing material waste and die damage.

End Reduction Draw Prep

Annealing Furnace

Enhances the material structure of the steel, improving its ductility and strength, which is crucial for successful cold drawing. Controlled heat treatment cycles ensure uniform metallurgical properties throughout each bar.

Fully Automated Phosphating and Soaping Line for lubrication

Fully Automated Phosphating & Soaping Line

Applies a uniform lubricating film to the steel bars, significantly improving the cold drawing process and enhancing surface quality. Full automation ensures consistent coating thickness across every batch.

Lubrication Surface Quality Automated

Cold Drawing Machines

The core equipment in our production process, capable of performing multiple drawing passes to achieve precise dimensions and high tensile strength. Our fleet includes combined drawing machines, inline cold drawing machines, and heavy-duty units for large-diameter, high-strength materials.

Polishing and Straightening Machine for post-treatment of steel bars

Polishing & Straightness

Our polishing machine achieves a superior surface finish (Ra 0.4-0.8) for a smooth, high-quality result, while the straightening machine ensures excellent straightness across the full bar length -- meeting the tightest flatness tolerances.

Ra 0.4-0.8 Polishing Straightening

Precision Cutting Machine

Provides accurate length control and tight tolerances, ensuring that the steel bars are cut to the exact specifications required. Our CNC-controlled cutting system minimises kerf loss and delivers burr-free, square-end cuts.

Length Control Tight Tolerance

Precision Cutting Machine for accurate steel bar length control

Chamfering Machine

Processes the ends of the bars, creating a clean finish and precise edge for easy handling and further processing. Chamfered ends reduce the risk of injury during handling and improve fit during assembly.

End Finishing Clean Edge

Packaging Equipment

Automated bundling and labeling system for organized packaging, ensuring that our products are ready for shipment. Custom packaging options including anti-corrosion wrapping and export-grade crating are available on request.
