What are people saying about us
Our customers have consistently shared positive feedback about our cables and services. Here’s what they say about US:
Luis Fernando Pérez - Venezuela - Office Building Project
The wires are of very good quality. The cables need to pass through long pipes and corners, and the cables are very flexible. We also ordered fire-resistant wires, which have been tested by a testing agency and found to be without problems.
Thomas Baker - USA - Factory construction
GERITEL WIRE's engineering team was very professional. They offered suggestions based on our cable requirements, and we found more suitable cable models. Subsequent operation has been stable without any problems.
Ricardo José Herrera - Dominican - Hotel Project
Due to the tight schedule of the hotel project, we had to adjust the usage quantity several times. GERITEL WIRE supplier was very flexible in terms of delivery and packaging, with fast delivery times. The wire reels were clearly labeled, making on-site counting and distribution very convenient.
