Industrial Alignment
Engineered for Indonesia’s Toughest Industrial Frontiers
From the world-class nickel smelting hubs in Central Sulawesi to maritime offshore assets in the Java Sea, our titanium mesh anodes and auxiliary fasteners solve severe corrosion, intense current density, and chemical wear challenges.
HPAL Nickel & Cobalt Hydrometallurgy
Indonesian High-Pressure Acid Leach (HPAL) operations (Morowali, Weda Bay, Obi Island) extract nickel and cobalt under intense sulfuric acid concentrations. Our dimensionally stable MMO-coated titanium mesh anodes exhibit near-zero substrate erosion, reducing plant cell maintenance downtime by over 45%.
Marine Cathodic Protection (ICCP)
Indonesia’s expansive archipelagic marine infrastructure—offshore FPSO vessels, deep-water terminals in Tanjung Priok, and submarine pipelines—demands high-reliability mixed metal oxide (MMO) ribbon and mesh anodes that withstand high salinity, tropical water temps, and chlorine evolution.
Palm Oil Effluent (POME) Electrochemical Treatment
In Sumatra and Kalimantan, palm oil mills utilize electro-coagulation and electro-oxidation cells to break down dense biochemical oxygen demand (BOD) and chemical oxygen demand (COD). Our iridium-tantalum coated mesh provides optimal oxygen evolution overpotentials for swift organic mineralisation.

Emerging Trends Driving Titanium Mesh Anode Procurement in Indonesia
The industrial landscape in Southeast Asia is shifting rapidly toward downstream resource processing. Following the Indonesian government’s strict raw mineral export bans under Law No. 3/2020 on Mineral and Coal Mining (Minerba), the nation has transformed into the epicenter of high-purity battery chemicals and metallurgical processing. This structural shift has created an unprecedented surge in demand for Dimensionally Stable Anodes (DSA®), electrodeposition substrates, and inert titanium fastening infrastructure.
1. Downstream Nickel Laterite Processing and Electrowinning (EW)
Traditional pyrometallurgical processing (RKEF) produces ferronickel and nickel pig iron, consuming massive electrical energy while generating high carbon footprints. In contrast, newly commissioned hydrometallurgical operations rely on high-pressure acid leaching followed by Mixed Hydroxide Precipitate (MHP) refining into battery-grade nickel sulfate (NiSO4) and cobalt sulfate (CoSO4). The final electrowinning phases require titanium mesh anodes capable of enduring aggressive sulfuric acid electrolytes (150–200 g/L H2SO4) at operating temperatures surpassing 60°C without shedding catalytic coatings.
2. Sustainable Coastal Desalination & Seawater Electrolysis
As remote industrial parks develop across Halmahera and Maluku, reliable freshwater supply has become a strategic necessity. Industrial-scale seawater electrochlorination systems are deployed to generate in-situ sodium hypochlorite (NaOCl) for marine bio-fouling suppression in turbine condenser cooling loops. Titanium expanded mesh coated with multi-layer Ruthenium-Iridium Oxide (RuO2-IrO2) delivers elevated chlorine evolution efficiency (>85%) with exceptionally low cell voltages, mitigating system power draw across remote microgrids.

3. Supply Chain Security and Strict Traceability
Procurement departments in Jakarta, Surabaya, and Balikpapan face significant challenges when procuring unverified titanium hardware. Generic distributors often deliver titanium meshes contaminated with iron inclusions or irregular expansion slitting, resulting in premature passivation, coating blister formation, and catastrophic short-circuits across electrolyzer frames. Direct sourcing from Baoji-based primary manufacturers guarantees ASTM B265 compliant Grade 1/Grade 2 substrates paired with ISO-verified thermal decomposition coating regimes.

Frequently Asked Questions by Indonesian Buyers
Essential guidance addressing technical specifications, logistics to Indonesian ports, customs, and installation best practices.
Q1: How do you choose between GR1 and GR2 titanium substrates for mesh anodes?
Commercially Pure Grade 1 (GR1) offers superior mechanical ductility, making it ideal for micro-expansion mesh patterns with high open-area ratios without micro-fracturing along strand knuckles. Grade 2 (GR2) provides higher structural tensile strength, which is preferred for self-supporting anode baskets or heavy busbars used in aggressive hydrometallurgical electrowinning cells.
Q2: What are the lead times and shipping routes to Jakarta and Morowali?
Standard expanded titanium mesh patterns and catalog fasteners are stocked for dispatch within 5–7 days. Custom fabrication (stamping, busbar TIG welding, catalytic thermal baking) typically takes 15–25 days. Shipments are consolidated through Qingdao or Shanghai ports directly to Tanjung Priok (Jakarta), Tanjung Perak (Surabaya), or direct container feeder lines servicing Morowali and Weda Bay.
Q3: Can you fabricate custom anode geometry according to existing cell drawings?
Yes. Our engineering department processes 2D CAD (DWG, DXF, PDF) and 3D solid models (STEP, IGES). We fabricate custom-flanged anode frames, cylindrical tube anodes for pipeline cathodic protection, and slotted assemblies using our in-house multi-axis CNC machines and cold-heading tooling.
Q4: Why are GR5 titanium fasteners mandatory for anode busbar connections?
Standard stainless steel fasteners (304 or 316) suffer severe pitting, crevice corrosion, and galvanic degradation when coupled with titanium in chloride or sulfate environments. GR5 (Ti-6Al-4V) titanium fasteners deliver yield strengths exceeding 828 MPa, preventing loosening from thermal cycling while eliminating galvanic corrosion across your current-carrying junctions.
Q5: What documentation is provided for Indonesian customs clearance and SNI/KSO audits?
Every commercial order is accompanied by comprehensive EN 10204 3.1 Mill Test Certificates (MTC) stating precise chemical composition (O, N, H, C, Fe, Ti balance) and mechanical test data. We also furnish Certificate of Origin (Form E for ASEAN-China preferential tariffs), coating thickness verification reports (XRF), and commercial documentation tailored for smooth customs processing.
Q6: How is coating longevity verified before delivery?
We execute Accelerated Life Testing (ALT) per ASTM standards in high-concentration acidic baths under elevated current densities. Furthermore, cross-sectional SEM microscopy and thermal shock tests (quenched from 450°C to ambient water) ensure the MMO catalytic layer exhibits outstanding mechanical adhesion and zero spalling.
