Electrical Conductors

High-Conductivity Copper Bus-bar

Our Copper Bus-bars are designed and extruded specifically for heavy-duty electrical engineering systems. They serve as reliable, low-resistance conductors in power distribution systems, transformer assemblies, switchboards, and electrical control panels.

We manufacture bus-bars with a copper purity of over 99.95%, ensuring maximum energy transmission with minimum heat build-up. All products comply strictly with the KS D 5530 (Korean Industrial Standards) and JIS specifications.

Technical Specifications:

Property	Specification Target
Copper Content (Cu)	≥ 99.95%
Electrical Conductivity	≥ 98% IACS
Standard Compliance	KS D 5530 / JIS H3140
Edges Profile	Sharp, Rounded Corners, Full Radius

Casting Materials

Copper Billet & Slab Casting

PT Sungming Metal Indonesia produces high-density copper billets and slabs through a continuous horizontal casting process. These intermediate materials are ideal for secondary manufacturers who operate rolling mills, wire drawing plants, and sheet metal factories.

The smelting process uses top-tier recycled non-ferrous scrap and cathode materials to achieve consistent structural density and prevent internal porosity, making it highly reliable for heavy extrusion and machining.

Form factor	Standard Dimensions	Primary Usage
Copper Billets	Diameter 90mm - 250mm	Extrusion, Wire Drawing, Pipe Manufacturing
Copper Slabs	Custom thicknesses & widths	Copper Plate & Strip Rolling Lines

Industrial Supplies

Steel Materials & Non-Ferrous Alloys

We supply premium steel products and metal alloys for industrial structures, heavy equipment frameworks, and shipbuilding. Through our global partnerships in Korea and Singapore, we handle supply chains for:

• 🔯 Structural carbon steel sheets, H-beams, and channels.
• 🔯 Aluminum ingot blocks, brass alloys, and zinc materials.
• 🔯 Cold-rolled and hot-rolled coils for local steel fabrication.

Custom Fabrication

Custom Extrusion & CNC Fabrications

PT Sungming Metal Indonesia offers tailored manufacturing services. Customers can supply mechanical blueprints for specialized bus-bars, connectors, or non-standard profiles.

Our workshop handles bending, hole-punching, silver/tin plating, and precision machining, delivering drop-in components directly to electrical assembly factories and grid substations.
