Our history
PROMRESOURCE TRADING LTD was established as a result of more than 20 years of experience accumulated by its shareholders and management team.
The expertise gained through previous business activities in the jurisdictions of the United Kingdom, Cyprus and Switzerland enabled us to define the company’s key area of focus: the supply of products for industrial enterprises.
Over the years, international product supplies organized by our companies have influenced the markets of individual countries and, in some cases, accounted for up to 10% of the total commodity market volume.
Successful operations during challenging periods of the global economy have allowed us to preserve and expand our network of partners, including leading global manufacturers in mechanical engineering, metallurgy, mining and raw material processing, as well as companies engaged in the production and processing of agricultural products.
Professionals who gained experience working in our companies over the years are now successful managers and are well known among producers of metallurgical products.
Our mission is straightforward: to create and maintain a balance between supply and demand for producers and consumers in the industrial sector.
By focusing on this goal, PROMRESOURCE TRADING LTD is committed to delivering the best possible results for every client, ensuring efficiency, reliability, and long-term value in every partnership.
Long-term perspective
The growing use of electronic components in global industrial production, together with increasing demand for elements of telecommunication systems, data protection, information transmission, and automated computer systems used in data processing and control centers, creates significant opportunities for long-term growth in international trade.
Thanks to deep market knowledge, many years of experience of our owners and management team, as well as the support of our reliable partners, PROMRESOURCE TRADING LTD has all the prerequisites for sustainable growth. We remain confident in the future of our business activities and in the continued development of the company.
Our Activities
Having our own working capital, we provide advance financing to manufacturers, guarantee supply volumes, control product quality, arrange delivery from the manufacturer to the end customer, and provide deferred payment terms to customers for delivered products.
We assume financial risks related to product quality and delivery, while ensuring a competitive market price for each supply.
Maintaining a balance between demand and supply for raw materials and products allows us to rely on our deep market knowledge and many years of experience.


The company’s main goal and strategy is long-term and mutually beneficial partnership.
Our mission is quite simple: we strive to find the right balance between supply and demand for manufacturers. In pursuing this goal, we aim to deliver the best possible results for our clients.

BendCom® bending-resistant single-mode fiber G.657.A2
G.657.A2 bend-resistant single-mode optical fiber is designed for data centers, access networks, FTTx projects and telecommunications infrastructure. It offers low attenuation, excellent bending performance and high reliability for dense cable installation environments.
Product introduction
Bend Com G.657.A2 bend-insensitive single-mode optical fiber can provide two specifications with diameters of 200μm and 242μm, and is protected by special high-
performance acrylic resin composite material. The optical fiber still has excellent bending loss characteristics under the condition of reducing the size. Small-sized
optical fiber can save a lot of pipeline resources, improve the cable laying capacity and
construction efficiency, and is the best choice for broadband construction of metropolitan area network and access network in an “environment-friendly and energy-
saving society”.
Performance highlights
- Special composite coating material, good bending loss characteristics
- Less bending loss.
- Smallersize optical fiber can be selected, and the designed cross-sectional area
of optical cable isreduced by more than 30%, which improvesthe laying density
of optical cable and effectively saves pipeline resources.
Application scenario
- High-density metropolitan area network and access network in narrow
environment - Air-blown micro-cable
- FTTx
