Galvanized steel profiles are the ideal solution for structures that must withstand the weather, with a good balance between strength and weight and contained costs. We start from pre-galvanized steel coils: the zinc layer creates a protective barrier against corrosion that stays with the profile through every processing step. The result is a component suited to construction, industry, energy and urban furniture.

How we manufacture galvanized steel profiles
Roll forming, stamping, punching and bending
The production of galvanized steel profiles starts from pre-galvanized sheet in coil. The strip is slit to the required width and cold formed into the desired section, with full freedom of geometry and thickness. The zinc layer protects the profile from rust and oxidation, making it suitable for outdoor use and humid environments.
Cold roll forming
The galvanized sheet passes through a series of shaped rollers that gradually deform its section, allowing the creation of complex profiles while maintaining tight dimensional control.
Cold stamping
Using presses and molds, it is possible to form three-dimensional shapes with bends and ribs, meeting the needs of various industrial sectors.
Punching
Holes, slots, or various types of openings are created using precision machinery, often in line with profiling. This simplifies subsequent assembly in construction, mechanical, or light metalwork applications.
Bending
The use of rollers or specialized bending systems makes it possible to create curved or shaped profiles, which are in high demand in architectural applications or urban furniture.
The advantages of galvanized steel
Galvanized steel combines the strength of steel with effective corrosion protection, thanks to the zinc coating that prevents the formation of rust and oxidation. This feature makes it suitable for outdoor or harsh environments, offering an excellent combination of durability, practicality, and cost efficiency.
High corrosion protection
Galvanizing creates a shield against oxidation, preserving the material over time.
Good strength-to-weight ratio
It helps reduce loads on structures while maintaining solid resistance.
Design flexibility
Thanks to various processes (profiling, stamping, punching, bending), galvanized steel profiles can take on custom shapes with excellent dimensional tolerances.
Application versatility
The same profiles can be used in both indoor and outdoor environments due to their resistance to weathering and temperature fluctuations.
Types of galvanized steel profiles
Profiles can be open or closed, with standard or custom-designed configurations. Among the most requested formats are galvanized omega profiles, highly appreciated for their Ω-shape, which provides strength and application flexibility across different support structures. These profiles are suitable for multiple uses, ensuring stability without overloading the overall structure.

Frequently asked questions
What is the difference between profiles made from pre-galvanized coil and hot-dip galvanized profiles?
Profiles made from pre-galvanized coil are formed from sheet that is already coated: the cost is lower and the surface is uniform. Hot-dip galvanizing after fabrication deposits a thicker layer, including on cuts and holes, and is suited to the most aggressive exposures.
Can galvanized steel profiles be punched and bent?
Yes. Holes, slots and punching are made in line during roll forming, and profiles can be bent or calendered. The zinc layer follows the deformation of the material.
Where are galvanized steel profiles used?
Indoors and outdoors: construction, window frames, photovoltaic systems, greenhouses, industrial carpentry and urban furniture. They are suited to humid environments and temperature changes.
Applications
Thanks to their anti-corrosion properties, galvanized steel profiles are used in light and heavy construction, industrial carpentry and urban furniture. Galvanized profiles for window frames ensure stability and long life in humid environments, while galvanized profiles for photovoltaic systems support solar installations exposed to the weather. In agriculture we produce galvanized greenhouse profiles, and in interior construction galvanized drywall profiles make partition walls and suspended ceilings easy to install. For specific needs we produce special shapes such as galvanized omega profiles. To learn how the zinc coating protects steel, read our guide to zinc corrosion protection.
