Giuseppe & F.lli Bonaiti

What Giuseppe & F.lli Bonaiti does

Giuseppe & F.lli Bonaiti S.R.L. a socio unico is a privately held, family-owned Italian steel wire drawing company headquartered in Calolziocorte (Lecco province), tracing continuous operations to an 1826 founding and first documented workshop activity in Laorca in 1830. The company manufactures cold-drawn steel wire and wire rod through an integrated, single-site production chain built around three core processes: cold drawing (trafilatura a freddo) for dimensional precision and surface finish, controlled-atmosphere annealing in static bell and carriage furnaces (ricottura, with a new 16-tonne-per-cycle furnace commissioned in April 2023) for spheroidization and mechanical-property tuning, and skinpassing for low-elongation finishing. Its portfolio is organized into General Purpose Steel, Cold Stamping Steel (subdivided into non-heat-treated, quenched-and-tempered, and case-hardening grades), and Free-cutting Steel, with an in-house metallurgical laboratory issuing mechanical test certificates per work order and a 10-year worksheet / 1-year specimen traceability regime.

Commercial activity is a direct B2B sales-led model executed through commercial offices at the Calolziocorte site, with prices agreed quote-by-quote in writing on FCA (Free Carrier) Calolziocorte terms. Primary customers are fastener manufacturers producing screws and bolts for the automotive, mechanical engineering, and white-goods / appliance sectors; order confirmation and a 5-day buyer-carrier pickup window from "materials ready" notice govern logistics. The company is structured as a single-member SRL with €700,000 of fully paid-in capital and is UNI EN ISO 9001:2015 certified since 1997 (TÜV Italia); it is also a co-founder (with Itla) of the ITLA Bonaiti SPA joint venture for high-carbon cold-formed steel strips, to which it transferred its former Palazzago site in 2017.

Revenue model

1. Steel Wire and Wire Rod Sales: Giuseppe & F.lli Bonaiti generates revenue through the manufacture and sale of steel wire and wire rod products. Their product portfolio includes general purpose steel, cold stamping steel (subdivided into non-heat-treated, quenched-and-tempered, and case-hardening grades), and free-cutting (automatic) steel. Products are sold as finished or semi-finished steel wire in various surface conditions and delivery forms (coils, bundles, spools). Revenue is derived from direct B2B sales to manufacturers of fasteners (screws, bolts) and small metal parts. Pricing is FCA (Free Carrier) establishment of the Seller, net of VAT, with payment terms agreed in writing between the parties.

Core offering

Giuseppe & F.lli Bonaiti manufactures and sells steel wire and wire rod produced through cold drawing, controlled-atmosphere annealing, and skinpassing. Its core product lines are general purpose steel, cold stamping steel (subdivided into non-heat-treated, quenched-and-tempered, and case-hardening grades), and free-cutting (automatic) steel, supplied in coils, bundles, and spools with surface finishes such as bright, stearated, phosphated, polymer, or pickled. The offering is targeted at B2B customers producing fasteners, screws, bolts, and small metal parts for the automotive, mechanical engineering, and appliance sectors.

Product overview

Giuseppe & F.lli Bonaiti is a historic wire drawing company (trafileria) established in 1826, specializing in the production of steel wire and wire rods through cold working processes. The company's product portfolio centers on its core wire drawing capability with three main product lines: General Purpose Steel (non-alloy low carbon steels for general applications), Cold Stamping Steel (covering three sub-categories: steel not intended for heat treatment, quenched and tempered steels for high mechanical characteristics, and case hardening steels for surface wear resistance), and Free-cutting Steel for high-speed mechanical processing. These products are offered as wire rods and drawn steel wires in various delivery conditions (bright, phosphated, polymer, pickled surfaces) and are used primarily by manufacturers of fasteners (screws and bolts). Production processes include cold drawing, annealing, and skinpassing, supported by an in-house metal testing laboratory issuing mechanical test certificates.

Functional benefit

Products and services

• General Purpose Steel Wire and Wire Rod Non-alloy low carbon steel wire rods and drawn steel wires for general applications such as metallic carpentry, load-bearing structures, and parts requiring modest static stresses. Common steels with medium-low strength, not containing special alloy elements, not subjected to heat treatments other than annealing or normalizing. Supplied for B2B manufacturers.
• Cold Stamping Steel Wire and Wire Rod Steel wire rods and wires designed for high-speed cold forming processes, including three sub-grades: (1) steel not intended for heat treatment (medium/low carbon non-alloy steels with high ductility and excellent cold formability), (2) quenched and tempered steel (0.21%-0.60% carbon for high mechanical characteristics after heat treatment), and (3) case hardening steel (construction steels with <0.30% carbon for surface hardening via carburizing). Supplied to fastener and mechanical-parts manufacturers.
• Free-cutting Steel (Acciaio Automatico) Steel for high-speed mechanical processing, also called high machinability steel. Designed for high cutting speeds on automatic machines such as CNC lathes and machining centres. Contains sulphur for chip fragmentation, lead for reduced friction, and tellurium/bismuth for enhanced characteristics. Used by manufacturers producing small metal parts via CNC machining.
• In-house Metallurgical Testing and Mechanical Test Certification In-house metallurgical testing laboratory service that checks and monitors mechanical properties of each processed coil and issues a mechanical test certificate per work order, supporting customers' traceability and quality documentation needs.

• ItlacoreStrategic or Co-development Partner · 1 January 2017In 2017, Giuseppe & F.lli Bonaiti and Itla jointly founded ITLA Bonaiti SPA, which became Italy's first producer of high-carbon cold-formed steel strips. Giuseppe & F.lli Bonaiti transferred its entire Palazzago site (2,900 m² building on an 18,000 m² area) to the new company, which subsequently expanded the facility to 18,000 m². This represents a significant strategic co-development partnership in the cold-formed steel strips segment.
