GESIT is committed to delivering guaranteed product quality that meets project specifications, on-time delivery, and competitive pricing.

As an integrated manufacturer and fabricator of sacrificial anodes, impress currect cathodic protection (ICCP) materials for onshore and offshore cathodic protection and coating systems, GESIT offers a full in-house production capability supported by strict quality control, complete traceability, and compliance with international standards.

Five Essential Pillars

To fulfill thecommitments, GESIT focuses on five core pillars:

1. Streamlined Production & Material Management

Optimized manufacturing and inventory systems ensure consistent quality, minimal waste, and shorter lead times for reliable on-time delivery. Efficient resource usage also helps keep pricing competitive.

2. Qualified and Experienced Personnel

Skilled engineers and production teams maintain product quality, improve workflow efficiency, and reduce operational costs—supporting timely delivery and competitive pricing.

3. Comprehensive Facilities & Equipment

Reliable and well-maintained melting, fabrication, and handling equipment guarantee stable production output. Minimizing downtime allows uninterrupted manufacturing and cost efficiency.

4. In-House Laboratory & Strict Quality Control

Regularly calibrated instruments enable accurate chemical, electrochemical, and dimensional testing. Rigorous QC ensures compliance with specifications, early issue detection, and smooth delivery schedules.

5. Strong HSE Implementation

GESIT applies strict Health, Safety, and Environment standards across all operations. The use of electric furnaces and controlled processes reduces environmental impact while supporting a safe and efficient workplace.
