    Internally polished and rolled AISI tubes:
    a quality product

    Bricom Srl has always concentrated on commercialising internally polished and rolled AISI tubes. High precision, quality and speed of delivery are some of the key words to describe the work of this company that supplies high quality materials. Founded in 2016, Bricom builds on the experience of its owners, who founded the company after 30 years in the polished and rolled AISI tube market, a field of specialised applications where quality and precision are two key elements in satisfying customers’ purchasing criteria and in supplying materials which are suitable for installations with special requirements. It is also for this reason that Bricom has a quality system that defines high-level standardised procedures, thanks to which the UNI EN ISO 9001:2015 quality certification was obtained: it is not only a formality required by customers who are supplied with internally polished and rolled AISI tubes, but also an important starting point for the continuous improvement of the company. As mentioned, speed is also an important element: speed in preparing orders is part of the service that Bricom can provide to customers. For this reason, it is essential to have highly trained operators who can supervise all the stages and work to ensure that they are carried out with the utmost care: starting with the selection of materials in the warehouse, choosing the batches most suitable for the specific use, and up to the cutting and special processing of the internally polished and rolled AISI tubes. Packaging and all other operations related to the preparation of the order are also entrusted to experienced professionals. The internally polished and rolled AISI tubes marketed by Bricom are destined for Italian and European customers. The company is also active nationally and internationally through distribution networks that facilitate sales in countries which are otherwise difficult to reach directly. All this has led to steady growth, which has improved its numbers year after year on both the productivity and staff fronts, as well as strengthening its financial and technological assets with continuous new additions to space and machinery. In 2022, the company doubled the space in its headquarters with the aim of further improving the organisation and results.
