Chrome-Plated Tubes
Bricom Srl was founded in 2016 and immediately established itself as a supplier of quality chrome-plated tubes in a highly competitive industry. The company was able to build a solid reputation thanks to the preparation and experience of the founders, who had been working in this field for more than 30 years and were able to rely on a network of leading suppliers, which allowed them to gain the trust of their customers. In recent years, Bricom’s strong growth has impacted all the company’s figures: not only its economic results, but also those related to staff and company assets, which have also been consolidated in terms of technology, up to the doubling of production space in 2022 with the relocation of the headquarters. Today, the Italian and foreign customers that rely on Bricom are particularly concentrated in northern Italy and Europe, where some countries are also reached through local distributors. From the outset, quality and speed have been the characteristics that have made the company’s work stand out in the field of chrome-plated tubes, which has earned the trust of customers and suppliers alike, and which is also enshrined in an efficient quality system that regulates every stage of sales and has enabled the company to obtain UNI EN ISO 9001:2015 certification. This recognition is not only an excellent achievement, but it is considered a starting point for working every day according to high quality procedures. Speed in order fulfilment is another feature that Bricom has made a strong point of: being able to process the order and deliver chrome-plated tubes quickly has always been one of the company’s goals. Major companies from various sectors, primarily hydraulics and pneumatics, rely on Bricom for the supply of chrome-plated tubes, as they are looking for high-profile materials in both standard and custom sizes. In this way, Bricom has become a benchmark for the sale of chrome-plated tubes and can target new and expanding markets.
