Our grounding materials offer excellent conductivity, strong corrosion resistance and easy installation, and are the preferred choice for power substations, telecom base stations, building lightning protection, rail transit, wind and PV farms, oil & gas depots and mining/chemical explosion-proof sites.
▲ Copper-clad steel rod / stranded wire / warehouse stock
• Copper-clad steel grounding rod — copper conductivity with steel strength
• Zinc-clad steel grounding electrode — for strongly corrosive soils
• Copper-aluminium composite plate — lightweight and highly conductive
• Graphite grounding cable — corrosion-resistant and maintenance-free
• Copper-coated flat/round steel — upgrade over traditional earthing materials
• Ionic grounding electrode — high-efficiency resistance reduction
• Exothermic welding materials — dedicated to grounding-system joints
| Product | Size | Key Parameters |
|---|---|---|

| Cu-Al composite plate | Thickness 3–10 mm; width 100–600 mm | Cu 10–30%; conductivity ≥ 60% IACS |
| Graphite grounding cable | Φ16 / Φ20 / Φ25 mm, or flat 30×3 / 40×4 mm | Acid/alkali resistant; maintenance-free; life ≥ 30 years |
| Ionic grounding electrode | Φ50 / Φ60 mm; length 1.0–3.0 m | Long-lasting moisture; resistance ≤ 4 Ω |
| Exothermic welding moulds | For Φ14–Φ25 rods / 25×3 flat bars | Joint ampacity ≥ conductor; joint resistance ≤ 1 mΩ |
We supply high-purity Ti, Al, Cu, Ni and Pb (3N5–6N) as ingots, rods, plates, strips, pellets and wires for semiconductor sputtering targets, evaporation coating, chemical and medical applications. Purity grades, impurity limits and packing (vacuum-sealed, argon-protected) can be specified per project.
We buy Au/Ag/Pt/Pd/Rh/Ir scrap — plated parts, spent catalysts, solutions and sludges — plus rare metals such as tungsten, molybdenum, cobalt and indium. Service flow: on-site XRF screening → sealed sampling by both parties → laboratory assaying (fire assay / ICP) → settlement based on exchange reference prices. On-site sampling is available across Shandong.
