The Steel tubular pole: Through traditional technology and advanced technology and with the help

of multiple advanced machines, we have developed advanced steel tubular poles. Varying from 10kV

to 220kV, type and application scope of steel tube poles from the Company are wide, including pole

types of single-circuit and double-circuits overhead lines. The Company owns two manufacturing

workshops and the annual output can be 36,000t. The Company frequently provides a reliable solution

for basic specification of steel tubular pole, special crossarm requirement and configuration of multiple

accessories. The Company has obtained rich production experience in the challenging production field

of steel tubular poles over years, so as to meet needs under conditions of various geological landforms

and wind speeds.

The Company owns an advanced management system. For the whole process of order signing, raw

material preparation, sample testing, product processing and manufacturing and transportation, the

Company uses an advanced internal working platform generally to achieve sharing and transmission of

internal resources; it is simple but no working procedures or related services are missing; design and

manufacturing technology are integrated, so as to achieve seamless connection between various

departments, shorten the overall work cycling time, improve the work efficiency and meet the current

needs of rapid development.

lines of China.

Since 2000, HENAN DINGLI has been actively developing international business, successively built

Ecuador, Cambodia manufacturing Base, Quito tower design center, Spain, Peru, Chile and other

overseas service centers. We have got a number of international certificates, such as ISO certificate

covering design, equipment and construction, AWS welding certificate, ASTM system certificate, Chile

NCH 203 certificate, Colombia RETIE certificate, Costa Rica material quality Certificate, etc. By the end

of 2018, the overall proportion of international business is more than 30% of the company's main revenue.

We have provided high-quality products and services to more than 100 customers in 33 countries,

Our poles as normal cover by Mat or straw bale at the top and bottom and wood between the poles

to avoid the damage on the galvanization of the pole ,anyway also can following by client required ,

The loading capacity of 40HC or OT an be calculated calculation base on the client actually

specification and data.

International Fully Automatic Pollution-free Galvanizing Line

All the production line of galvanization is sealed off, it is operated by 7 workers with a yearly

capacity of 160,000 tons.

In the new production line, we invest whole package of lifting equipment, all the loading works

will be completed in our factory, in this case, it will be avoided two times loading during transportation,

we are doing our best to protecting our products as always.

The new production line has improved on the part number tracking system, with this system we are

doing better to avoid the missing parts problem

Product Testing:

On December 16, 2018, the steel poles FAT test for project 20kv transmission line in DR-Congo

were carried out in our company's

steel pole test workshop. Participating in the test were representatives of the Spanish EPC and

representatives team from the

Democratic State Grid of DR- Congo. A total of six representatives came to witness the results of

the FAT test. There had 6

types of steel pole were carried out the FAT test. Items of FAT test includes: Material Test, Proofing

Test and Loading Test.

Customers are very satisfied with the test results of our products. The higher test results show that

the product quality of

our steel poles is very reliable.
