What Sipa does

Sipa SpA is an Italian manufacturer of custom special steel profiles, founded in 1981 and headquartered in Carnate (Monza e Brianza), Italy. The company operates a B2B direct-sales model with 25 employees and an annual production capacity of approximately 1,500 tons, producing more than 1,550 distinct profile shapes. Sipa is subject to the management and coordination of Calvi-Holding SpA and operates as part of the Calvi S.p.A. Group (within the wider RISA Group), alongside siblings Calvi and Rathbone.

The company's core technology is cold drawing and cold rolling of steel at room temperature, producing profiles with tight dimensional tolerances, smooth surface finishes, and enhanced mechanical properties through strain hardening. The product portfolio comprises cold-drawn special profiles, cold-rolled special profiles, and a stock catalog of standard profiles (including UNI 8953 splined shafts and DIN 508 T-blocks), supported by add-on services such as cutting-to-size, testing with certification, packaging, mechanical machining, heat treatment, and surface treatment. Sipa works a broad range of steel grades including construction steels (e.g., S235JRG1), case hardening steels (e.g., 16MnCr5), tempered steels (e.g., 42CrMo4), bearing steels (100Cr6), spring steels (55Si7), and tool steels.

Sipa serves industrial OEM customers across eight verticals: automation, automotive, furniture, defense, infrastructure, machines, general mechanics, and transport, with geographic reach into Europe (Italy), Germany, and North America via the parent group. Pricing is quotation-based with no public price list, and revenue is generated through one-off manufacturing contracts rather than recurring licensing. The company holds UNI EN ISO 9001:2015 certification and markets primarily through its corporate website, industry news content, and trade fair participation (including MECSPE in Bologna and IWA OutdoorClassics in Nuremberg). Between 2024 and 2025, Sipa undertook a group-wide rebranding alongside Calvi and Rathbone to reposition under the unified Calvi S.p.A. Group identity.

Functional benefit

Products and services

• Cold-Drawn Special Profiles Custom cold-drawn steel profiles manufactured by pulling steel through shaped dies at room temperature, producing complex geometries with tight tolerances, high surface quality, and improved mechanical properties (greater hardness, strength, and toughness) without material removal. Targeted at industrial customers in automation, automotive, defense, machinery, and other sectors.
• Cold-Rolled Special Profiles Custom cold-rolled steel profiles formed at room temperature by passing steel through rollers to produce precise shapes, reduced thickness, and smooth uniform surfaces with excellent dimensional tolerances and straightness. Intended for industrial applications requiring robustness and manufacturing efficiency.
• Standard Profiles (Splined Shafts and T-Blocks) Ready-to-use standard cold-drawn and cold-rolled profiles in C45 and stainless steel, including cold-drawn splined shafts conforming to UNI 8953 and T-blocks according to DIN 508, available from stock for fast delivery to industrial customers.
• Additional Manufacturing Services Supplementary manufacturing services including sampling, custom cutting to size, testing and product analysis with certifications, custom packaging, mechanical machining, heat treatment, and surface treatment, provided alongside custom and standard profile production for industrial customers.
