Pre-painted galvanised steel sheet S.Steel
What is pre-painted galvanised steel
Pre-painted galvanised steel is a cold-rolled steel sheet covered with a zinc layer (for corrosion protection) and a finish polymer layer (for colour and additional protection). The material is available in both sheets and coils, which is convenient for roofing and facade work.
How pre-painted galvanised steel is produced
The process includes several stages. First, the steel sheet is cleaned and degreased. Then it is passed through a bath with molten zinc (hot-dip galvanising) – a protective layer is formed. After this, a primer and finish polymer coating (polyester, PVDF, Pural, and others) are applied. The coating is polymerised in a high-temperature oven, ensuring strong adhesion to the metal.
Why this is a cost-effective solution for a facade
-
Affordable price. Galvanised steel with coating is significantly cheaper than stainless steel, copper, aluminium, and brass.
-
Wide colour range. Any colour from the RAL catalogue: matte, gloss, metallics, wood-grain or stone textures.
-
Corrosion resistance. Zinc protects steel from rust, and polymer coating protects from ultraviolet rays, moisture, and scratches.
-
Durability. With proper coating selection, service life is 15–40 years.
-
Ease of installation. Sheets are easy to cut, drill, and profile.
Types of polymer coatings
The durability and appearance of pre-painted galvanised steel depend on the type of finish coating. Let us consider the main options.
Polyester (PE)
A classic gloss coating based on polyester resin. Layer thickness – 20–25 μm.
Advantages: low cost, good colour fastness, elasticity (suitable for bending).
Disadvantages: sensitive to scratches, less resistant to aggressive environments.
Where it is used: facades and roofing of private homes, interior finishing, elements without high wear resistance requirements.
Super-polyester (HD PE)
An improved version of polyester with additives that increase strength and UV resistance. Layer thickness – 25–35 μm.
Advantages: higher scratch resistance, fade resistance, good price-to-quality ratio.
Where it is used: facades and roofing of commercial buildings, cottages, office centres.
PVDF (polyvinylidene fluoride)
A coating based on polyvinylidene fluoride. Layer thickness – 25–40 μm. The most expensive and most reliable option.
Advantages: maximum UV resistance (does not fade for decades), high scratch and chemical resistance, maintains gloss and colour in aggressive environments.
Where it is used: facades of high-rise buildings and business centres, facilities on marine coastlines, in industrial zones.
Pural (polyurethane)
A coating based on polyurethane with polyamide additives. Layer thickness – 50 μm.
Advantages: high resistance to mechanical damage, temperature fluctuations, and aggressive environments. Good colour retention.
Where it is used: roofing and facades in regions with harsh climates, industrial facilities.

Where pre-painted galvanised steel is used
Ventilated facades
Coated steel panels are mounted on a substructure with an air cavity. This allows for building insulation and facade moisture protection. A wide selection of colours gives architects freedom for creativity.
Suitable for: office centres, shopping malls, residential buildings, warehouses, hangars.
Roofing
Standing seam roofing made from pre-painted galvanised steel is a budget-friendly and reliable option. Sheets are connected with standing or horizontal seams without through holes, ensuring watertightness.
Suitable for: industrial buildings, warehouses, hangars, private homes.
Decorative elements
Sheets are used to make cornices, flashing, gutter pipes, canopies, window surrounds, and entrance details. Colour can be matched to the main facade or made contrasting.
Suitable for: any facilities where detailing is important.
Profiled sheet (corrugated metal)
Pre-painted galvanised steel is the basis for corrugated metal production, which is used for roofing, fences, facade panels, and partitions.
How to choose pre-painted galvanised steel
Sheet thickness
| Thickness | Application |
|---|---|
| 0.35–0.45 mm | Corrugated metal, decorative elements (non-load-bearing) |
| 0.5–0.6 mm | Facade panels, roofing with rafter spacing up to 80 cm |
| 0.7–0.9 mm | Roofing in snowy regions, industrial facades |
| 1.0–1.2 mm | High-load structures, load-bearing elements |
Coating type
-
For budget projects in moderate climates – polyester (PE).
-
For residential buildings and commercial facilities – super-polyester (HD PE).
-
For aggressive environments (marine coastline, industrial zone) – PVDF or Pural.
-
For harsh climates – Pural.
Galvanising class
The thicker the zinc layer, the longer the material will resist rusting at cut edges and scratches. For facades, a coating class of at least 140 g/m² is recommended.
Why buy pre-painted galvanised steel from the manufacturer
If you have decided to buy pre-painted galvanised sheet steel for building facade cladding, working directly with the manufacturer provides several important advantages.
Manufacturer prices
Without distributor and retail markups. Prices from the manufacturer for pre-painted galvanised steel for roofing per m² in Moscow are 15–25% below market prices.
Quality control
The manufacturer is responsible for the source steel, zinc coating thickness, and polymer coating quality. You receive material with a guarantee.
Any size for your project
The manufacturer cuts sheets to your dimensions or supplies coils. This minimises waste and accelerates installation.
Colour and coating stability
In a single batch, colour and texture are identical throughout the coil or sheet batch. No risk of colour variation on the facade.

Frequently asked questions
1. What is the difference between pre-painted galvanised steel and plain galvanised steel?
Plain galvanised steel has only a zinc coating (silver colour). Over time it dulls, may develop a white coating (zinc oxide), and requires painting. Pre-painted galvanised steel already has a finish colour layer that protects the zinc from corrosion and provides the desired shade.
2. Can pre-painted galvanised steel be used on a residential home roof?
Yes. It is one of the most popular roofing materials for private homes (especially in the form of metal tile or corrugated metal). It is important to choose the correct coating: polyester is suitable for most regions, Pural for snowy and windy areas, PVDF for homes by the sea.
3. What is the service life of pre-painted galvanised roofing?
With polyester (PE) – 10–15 years. With super-polyester (HD PE) – 15–25 years. With Pural and PVDF – 25–40 years. The key factor is environmental aggressiveness and installation quality (absence of scratches on cut edges).
4. What is cheaper – buying a pre-painted sheet or painting galvanised steel on-site?
A ready-painted sheet from the manufacturer is almost always cheaper and higher quality. On-site painting requires sandblasting, priming, and application of expensive weather-resistant paints. Factory coating is more uniform and durable than factory-applied coating.
5. What colour should I choose for the facade so it fades less?
Light colours (white, beige, light grey) fade more slowly than dark colours (blue, green, red, brown, black). PVDF and Pural coatings fade more slowly than polyester. For southern regions, always use coatings with high light fastness.
