What Is Galvanized Steel Sheet?
Galvanized steel sheet is a flat carbon steel product that has been coated with a layer of zinc by the hot dip galvanizing process. The zinc coating adheres metallurgically to the base metal, creating a durable and continuous barrier against corrosion. In everyday language, galvanized steel sheet is frequently referred to as GI sheet, galvanized iron sheet, galvanized sheet metal or simply zinc galvanized sheet.
In coil form it is known as galvanized steel sheet coil or DX51D galvanized sheet coil, which can be slit, cut-to-length or roll-formed into roofing, cladding, ducts and various fabricated components.
Standards and Technical Specifications – EN 10346 DX51D+Z
HL Metal typically supplies galvanized steel sheet EN 10346 DX51D and related grades, which are designed for forming and profiling. The galvanized sheet technical specifications EN 10346 define steel grades, zinc coating masses, mechanical properties and test conditions.
- Standard: EN 10346 – Continuously hot-dip coated steel flat products
- Grade: DX51D – general use, suitable for bending and profiling
- Coating: DX51D+Z100 to DX51D+Z275 (GI sheet & coil DX51D Z275 on request)
- Typical yield strength: approx. 140–300 MPa (depending on thickness and condition)
- Typical tensile strength: approx. 270–500 MPa
- Condition: As-coated, skin-passed, oiled or passivated depending on application
For specific forming, stamping or deep-drawing applications, alternative grades under EN 10346 can be supplied upon request, always supported with mill test certificates.
Galvanized Sheet Dimensions, Thickness and Weight Chart
HL Metal maintains a wide range of galvanized sheet stock sizes 1000×2000 / 1250×2500 mm for immediate delivery. Other dimensions, including 1500×3000 mm or custom cut-to-length sheets, are available depending on volume. The theoretical galvanized steel sheet weight chart below is based on the density of carbon steel; the additional zinc layer has a relatively small effect on total weight.
| Dimensions (mm) | Thickness (mm) | Approx. Weight per Sheet (kg) |
|---|---|---|
| 1000 × 2000 | 0.50 | ≈ 7.85 |
| 1000 × 2000 | 0.80 | ≈ 12.6 |
| 1000 × 2000 | 1.00 | ≈ 15.7 |
| 1250 × 2500 | 0.50 | ≈ 12.3 |
| 1250 × 2500 | 0.80 | ≈ 19.7 |
| 1250 × 2500 | 1.00 | ≈ 24.6 |
| 1250 × 2500 | 1.50 | ≈ 36.9 |
| 1250 × 2500 | 2.00 | ≈ 49.2 |
| 1500 × 3000 | 1.50 | ≈ 52.9 |
| 1500 × 3000 | 2.00 | ≈ 70,65 |
| 1500 × 3000 | 3.00 | ≈ 105,97 |
| 1500 × 3000 | 4.00 | ≈ 141,3 |
Values are indicative and calculated with a density of 7.85 g/cm³. For precise weights and custom coil widths, you can use our galvanized steel sheet weight chart & calculator .
Zinc Coatings Z100–Z275 and Corrosion Resistance Properties
The protective performance of a zinc galvanized sheet primarily depends on the coating mass. HL Metal supplies hot dip galvanized steel sheet Z100–Z275, carefully selected according to the environment and service life expectations.
- Z100 / Z140: lighter coatings for interior use, HVAC, ducting and dry environments
- Z200 / Z225: balanced protection for standard outdoor and roofing applications
- Z275 galvanized steel sheet: enhanced coating mass for demanding outdoor durability
Thanks to the sacrificial behaviour of zinc, galvanized steel sheet corrosion resistance properties remain effective even if small areas of the coating are damaged during cutting or forming. For particularly aggressive atmospheres, galvanized steel sheet can also be post-painted to form a duplex system, combining barrier and sacrificial protection.
Galvanized Steel Sheet for Roofing and Construction
Galvanized steel sheet for roofing and construction is a long-established solution in residential, commercial and industrial buildings. GI sheet metal is easy to profile, offering lightweight yet strong roofing and cladding systems with excellent water shedding and weather protection.
- Corrugated and trapezoidal hot dip galvanized sheet for construction
- Roofing and wall cladding for warehouses, workshops and agricultural buildings
- Gutters, flashings, ridge caps and accessory parts in galvanized sheet
- Structural decking and secondary framing elements in GI sheet metal
For projects requiring additional insulation and thermal performance, galvanized steel sheet can be combined with sandwich panels or insulated roofing systems, providing both structural strength and long-term durability.
Galvanized Steel Sheet for HVAC Systems and Industrial Applications
Due to its clean surface, formability and corrosion protection, galvanized steel sheet for HVAC systems has become the industry standard for ductwork, ventilation and air distribution components. Galvanized sheet for ducting and ventilation ensures low air leakage, hygienic surfaces and long service life in commercial buildings, hospitals and industrial facilities.
- Rectangular and round ducts, plenums and air handling components
- Fan casings, filter housings and air distribution boxes
- Galvanized sheet for fencing and fabrication of frames, gates and security enclosures
- Galvanized sheet for agricultural buildings, animal shelters and storage units
In general, galvanized steel sheet for industrial applications is used for cabinets, machine guards, electrical enclosures, conveyor covers and countless fabricated parts where corrosion protection and cost-efficiency are important.
Galvanized Steel Sheet vs Cold Rolled Steel Sheet
While cold rolled steel sheet offers a very smooth surface and tight dimensional tolerances, it lacks built-in corrosion protection. Galvanized steel sheet vs cold rolled steel sheet can be summarized as follows:
- Cold rolled steel sheet: excellent surface finish and formability, but requires subsequent painting or coating for corrosion resistance.
- Galvanized steel sheet: slightly less perfect surface but incorporates a zinc coating that protects both bare edges and damaged areas through sacrificial action, reducing maintenance costs.
In many projects, the ideal solution is a combination: cold rolled as a base material in selected areas, and DX51D+Z galvanized steel sheet and plate where long-term corrosion protection is essential.
Galvanized Steel Sheet Price, Per Ton and Per Square Metre
Galvanized steel sheet price is influenced by the same core factors as other steel products: global steel and zinc markets, coating mass, thickness, coil width, order size and logistics. HL Metal offers competitive galvanized steel sheet price per ton for bulk coils and a transparent galvanized sheet metal price list for regular customers and distributors.
For roofing, cladding and ducting projects, contractors often compare cost on an area basis. We therefore provide galvanized sheet per square meter price on request, taking into account the specific thickness (for example 0.5 mm galvanized sheet vs 1 mm galvanized sheet), coating mass and final destination.

FAQ
What is Galvanized Sheet?
Galvanized Steel Sheet is steel sheet coated with zinc to protect against corrosion. The coating method (hot-dip vs electro-galvanized) affects thickness and performance.
Galvanized Steel Sheet vs Stainless Steel Sheet — which to choose?
Choose galvanized when cost-effective corrosion protection is needed and stainless when higher corrosion resistance, aesthetic or non-magnetic properties are essential. We can advise based on application and life-cycle cost.
How do I find the Best Galvanized Steel Sheet for Outdoor Use?
Consider coating weight (Z275 or higher for coastal use), post-treatment (paint, passivation) and expected lifetime. Our technical team can propose an optimized specification.
Is there a Durable Galvanized Steel Sheet for Industrial Use?
Yes — structural grades like S350GD Galvanized Sheet with heavier zinc coatings provide robust performance for industrial environments. Consult Case Studies for examples.
Maintenance and Longevity — Maintenance-Free Galvanized Steel Sheet?
No metal is entirely maintenance-free, but properly specified and coated Galvanized Steel Sheet with correct detailing and protective finishes can provide decades of low-maintenance service.
