    polished or rolled tubes

    Bricom Srl specialises in the supply of cold-drawn welded or non-welded polished or rolled tubes. This type of product is specifically aimed at the construction of cylinder liners for hydraulic systems: they offer maximum safety for pressure resistance, a fundamental characteristic for operators in the sector. Cold-drawn welded or non-welded polished or rolled tubes are produced in all dimensions for every specific requirement in the field of hydraulics, and in different steel types and delivery states. The range marketed by Bricom includes EN 10305-1 cold-drawn non-welded tubes and EN 10305-2 cold-drawn welded tubes. In addition to the marketing of standard material, Bricom also provides a cut-to-size service using band saws. As with all machining operations at Bricom, these are carried out by highly skilled operators following quality-set procedures. Established in 2016, the company immediately benefited from the experience of the founders, who have been in the industry for more than 30 years and quickly established trusted relationships with high-profile suppliers and customers. The company’s quality system, enshrined in its UNI EN ISO 9001:2015 certification, has played a key role in Bricom’s status as a high-end supplier of cold-drawn welded or non-welded polished or rolled tubes. Another strength that Bricom’s customers appreciated was the speed of delivery, which remains a goal to further improve services and strengthen the market position. The company has also placed a great deal of emphasis on packaging, logistics and shipping management to ensure the maximum punctuality of deliveries. Bricom operates on the Italian and international front, particularly in countries in Europe, where it is also supported by a network of distributors.
