What are people saying about us

Reliable factory quality, fast delivery and professional technical support for bulk wire orders.

Copper THHN/THWN-2 Wire supplier

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.

UL 83 Copper Building Wire

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.

What is your quality assurance process?

We will select and inspect the raw material and conduct strict quality inspections on each batch of raw materials. During the production process, the factory usually uses automated equipment and online detection systems for real-time monitoring. For example, the diameter of the copper wire, the thickness of the insulation material, and the twisting process during the wire drawing process all need to be precisely controlled. At the same time, we regularly take a certain number of wire and cable samples for inspection. These inspections include, but are not limited to, tests such as size, insulation resistance, conductivity, and mechanical strength. Each batch of wires and cables produced will be fully tested before leaving the factory. If quality problems are found in the product testing, the factory will take "traceback" measures to find the root cause of the problem and correct possible deviations in the production process. After production is completed, all wire and cable products will undergo a final quality inspection. In the packaging stage, the wires and cables will be properly packaged according to the specifications to ensure that they are not damaged during transportation. In addition, we have a professional after-sales team to respond to customer feedback and complaints promptly to ensure that problems encountered by users during use are solved promptly. In addition, the factory will regularly visit customers to collect product usage feedback and further improve product quality.
