Hot-dip galvanizing: long-lasting protection for steel products

Hot-dip galvanizing is a process that protects steel from corrosion by immersing the product in molten zinc. The result is a zinc coating metallurgically bonded to the steel, ensuring strength, reliability and durability over time.

At Bordignon Group, hot-dip galvanizing is not just a production step, but a process managed with meticulous attention to detail. Each product is analyzed based on its characteristics, intended use, and the environmental conditions to which it will be exposed, ensuring a result consistent with technical and design expectations.

The value of our service lies in our ability to integrate mastery with process control and customer relationships. Throughout the process, from the initial consultation to operational support, we approach each project with a focus on quality and consistent results.

How do we support our customers from consultation to delivery of the galvanized part?

Alberto is one of our Area Managers for hot-dip galvanizing.
His approach is practical, solution-oriented, and focused on long-term relationships.

For him, the consultation phase is strategic and consists of:

  • Analysis of project needs, to understand the application context, technical constraints and customer objectives
  • Direct consultation with designers and technical representatives to identify the most effective solutions right from the initial stages
  • Evaluation of product characteristics, based on the hot-dip galvanizing process and the required performance
  • Support in defining technical choices, sharing expertise and suggestions to improve the final result
  • Building an ongoing relationship based on trust, availability, and the ability to concretely respond to operational needs

An approach that transforms consulting into a valuable opportunity, helping to prevent critical issues, optimize the process, and ensure reliable results over time.

How are the surfaces of the parts to be galvanized prepared?

Cleanliness is the foundation of any good galvanizing.

  • Through degreasing, we remove oils, greases, and organic residues.
  • Through pickling, we restore the steel to its bare metal state, eliminating oxides, mill scale, and rust.
  • This is followed by washing to avoid cross-contamination between stages

Each step is monitored to ensure that the surface is suitable for galvanizing.

A monitored process in every phase

The quality of hot-dip galvanizing depends on the care with which each step is handled. This is why we operate through structured procedures that guarantee:

  • Careful surface preparation
  • Constant monitoring of process parameters
  • Coating uniformity
  • Compliance with relevant standards

Each phase is designed to contribute to a common goal: protecting the items over time, reducing maintenance and ensuring the durability of the structures.

Large-scale hot-dip galvanizing

Production capacity and complexity management

Large-scale hot-dip galvanizing is one of Bordignon Group’s core specialties. Thanks to some of the largest facilities in Europe, we are able to process complex and heavy components, maintaining the same quality standards required for every new process.
The ability to galvanize components up to 19 meters in length and weighing up to 30 tons allows us to meet the needs of sectors such as infrastructure, heavy carpentry, energy, and industrial construction.

Tailored technical management

Processing large-scale components requires a specific approach, based on:

  • Preliminary study of the structure
  • Design of correct hooking and handling points
  • Control of zinc immersion and drainage points
  • Dedicated and coordinated logistic activities

Each step is monitored to ensure a surface chemically ready for galvanizing.

Process and Logistics Integration

The management of non-standard components does not involves galvanizing only, but the entire operational flow. For this reason, Bordignon Group integrates:

  • Specialized internal handling
  • Oversized load logistic & transport
  • Coordinated planning between production and inbound/outbound logistics

An organized system that allows even the most complex processes to be handled with continuity and efficiency.

Production Planning: Organization, Precision, and Process Efficiency

Mirco is our production planning manager.
For him, planning is a central phase, which is built through:

  • Analysis of incoming orders, evaluating priorities, technical characteristics, and required lead times and turnaround time
  • Organization of production flows to ensure continuity and balance between different processes (perchè processes?? Cosa intendiamo?)
  • Coordination with factory’s handling and operations to align timescales, resources, and production capacity
  • Optimization of process sequences, reducing waiting times and improving overall efficiency
  • Constant monitoring of progress to promptly intervene in the event of changes or issues that might be critical

This work enables us to transform operational complexity into a structured, reliable process consistent with quality and service objectives.

Logistics: operational continuity along the entire supply chain

Logistics is an integral part of Bordignon Group’s service. It goes beyond transportation; it is a key element in ensuring continuity, safety, and compliance with deadlines throughout the hot-dip galvanizing process.
Through DMW Logistic, a dedicated logistics management organization, we coordinate the movement of products with organized and flexible solutions that can adapt to diverse operational needs, even for complex or non-standard components.
From collection scheduling to final delivery, each phase is carefully managed to ensure efficiency, traceability, and reliability.

This support completes the production process, simplifying the logistic and reducing the overall burden for the customer and thus contributing to the success of each project.
