Technical Support
Technical support on pre-sales stage. DINGLI has own survey and engineering company with more than 100 engineers.

We have special pre-sales engineer to work with customer at early stage of the project.

 

Site assistance
Site assistance in Latin American market, so far we have sales and service center in Spain, Chile, Bolivia,

Peru, Ecuador, Senegal, which will make a fast response for customer.

 

Warehouse and Emergency Supply
Warehouse and emergency supply for spare parts, damage parts and missing parts: DINGLI has built production

line in Quito and warehouse for transmission line and distribution network in Ecuador, Bolivia and Senegal with

common use spare parts.

 

Design and Consultant
Supported by both domestic engineering company and Quito tower design center, could provide technical

consultant and design service within our scope of work. For Quito tower design center, most of the engineers

are local staffs. The Design is based on ASTM protocols meantime with GB material standard, which will

reduce the weight, and avoid the replacement on the profiles to save the working time.

Package
Set-wisely packing or member-wisely packing as per client's requirements.
