How to choose the right color of corrugated sheeting for the roof and fence

Corrugated sheeting, like metal tiles and European picket fences, is made from galvanized steel sheet. Zinc coating is a good, but insufficient protection of metal from corrosion and minor external damage. Therefore, for roofs, fences, facade cladding and other structures that require high reliability and durability, products painted or coated with colored polymers are produced. This additional layer improves their performance and appearance. Its strength and service life do not depend on the color of the corrugated sheet, but the consumer has the opportunity to choose a shade that perfectly harmonizes with the landscape and exterior of the site.

In addition to standard colors, there are about 2000 more shades Source orenp.pro

Composition and properties of profiled sheets

Metal corrugated sheets are one of the most popular building materials today. There are a great many varieties of it. The materials differ in shape, wave or trapezoid height, in the thickness of the original metal blank , and also in the color of the protective and decorative coating applied to the surface.

The profiled sheet is made from high quality galvanized steel. The zinc layer present on it provides reliable protection of the metal from corrosion, and also, due to its thickness, from minor mechanical damage. In addition, a special paint or polymer is additionally applied to it.

The coating creates additional protection and significantly extends the service life of the corrugated sheet. If ordinary galvanized corrugated sheeting without special coating lasts 20-30 years, then coated corrugated sheeting can last about 50 years.

In addition to excellent protective properties, the polymer coating of the corrugated sheet can have almost any color. The most original design solutions become a reality thanks to the use of this material.

Modern corrugated sheeting combines excellent decorative qualities , as well as strength and durability.

Types of coatings

There are several types of polymer coating. One of the most durable is plastisol. Its thickness is 200 microns, and it has excellent anti-corrosion characteristics. If, for example, a corrugated sheet is exposed to active influence of external environmental factors, then this polymer coating should be chosen. True , the palette will not be very diverse, limited only to black, white, burgundy and cream colors.

In total, the corrugated sheet consists of four layers:

1. Galvanized corrugated sheeting.
2. Passivating layer.
3. Primer layer (5−10 microns).
4. Polymer coating with layer thickness from 25 to 100 microns for various coatings. The exceptions are enamel, varnish (10-12 microns for one-sided coating) and polymer coating (25-200 microns for double-sided coating).

Following plastisol is polyester or polyester paint. It is also extremely popular among consumers. There is a wide variety of colors present here. The coating thickness is 25 microns for a glossy finish and 35 for a matte finish.

Next on the list are acrylic paints (PVDF) - their coating thickness ranges from 20 to 40 microns. The excellent anti-corrosion qualities of PVDF are highly appreciated by customers, giving them a leading position in the market.

And finally, Pural (polyurethane-polyamide paint), which is more expensive than profiled sheets with polyester paint.

Corrugated sheet coloring options

To give the corrugated sheet the necessary characteristics, such as additional strength and corrosion protection, it is coated with a polymer or paint protective layer. In addition to all these properties there is an original color scheme. According to the nature of the applied coloring, metal profiles are distinguished:

1. Sheet painted only from the front surface. Intended for structures that are exposed to unfavorable conditions on only one side. For example, the roof of a building facade. A certain color scheme is applied to such corrugated sheeting from the “face”, while the back side remains gray.
2. In the second case, the sheet is painted the same color on both sides. Profiled sheets for fences and other barriers are painted in this way, as a result of which it is possible to achieve an aesthetic appearance on both sides.
3. The third option is double-sided painting, which can be not only of different colors, but also with different types of coating. This type of material is used on objects where various factors influence on both sides. In this case, the front surface must have an aesthetic appearance. One example of the use of such a profiled sheet is the construction of garage walls.

Color Standards

Profiled sheets, like other building materials, undergo standardization regulated by certain regulatory documents. The color range of the corrugated sheet is also subject to standardization. Colors and shades are presented in a wide palette, created on the basis of three generally accepted global standards:

• RAL is a European standard, represented by a wide range of shades, having 4 digits in the code.
• RR is a Finnish standard, the designation of which has 2 or 3 digits.
• HPS is an English standard that has the smallest number of colors in its palette. Its code consists of 4 numbers and 1 letter, which is not always present.
• PRELA is a Swedish standard.

The most popular coding is RAL. The color scheme along with the markings is indicated on cards or tables that the seller provides to the client. The color of the metal profile includes more than a thousand positions and is divided into 9 main ones.

In addition, there are the following RAL color catalogs:

• Classic - this scale was first developed in 1927, when the RAL standard was adopted. It is represented by 210 shades, where the first number indicates the series: 1 - yellow shades; 2 - orange, 3 - red, 4 - purple, 5 - blue, 6 - green, 7 - gray, 8 - brown; 9 - black and white.
• Design is a more advanced version of the RAL standard. It was developed in 1993, and initially it contained 1625 shades and colors in its palette. Periodically replenished, today it has 1688 shades, which are indicated by seven-digit digital codes.
• Effect is represented mostly by industrial colors, of which there are 490. Of these, 420 are matte and 70 are glossy. They are designated by a four-digit index and the letter M, which means metallic.
• Digital was developed in 1995 and is an analogue of RAL Design. It was created to work with computer design programs and computer-aided design (CAD) systems.

Profiled sheets coated with Printech polymer coating have recently enjoyed particular popularity and demand. Using offset technology, a design is applied to a galvanized sheet. It imitates natural wood: log, naive, pine wood (golden and stained oak, alpine pine). There are also types of corrugated sheeting, decorated with stone and brickwork, as well as imitating military camouflage. However, this coating option does not always combine well with other materials and can become boring very quickly.

Polyester according to the RAL standard is most often used as a coating for corrugated sheets. In addition, PRISMA coating (produced by the Corus concern), produced in original color palettes with a metallic effect, is in great demand.

What is RAL

RAL is a color matching system used in Europe to select the desired shade. In colloquial speech, RAL refers to the RAL Classic system, it is mainly used for paint and powder coating; modern production also widely uses it for coating corrugated sheets, plastic products, wood, and also for tearing metal tiles. Since 2013, RAL-approved products have been sold only with the use of a special hologram on the materials to minimize counterfeit color combinations. Substandard corrugated sheets may visually appear different shades under different light sources, which is unacceptable for world standards.

Profiled sheet for fence

As mentioned above, there is a profiled sheet that is painted on both sides. It is an architectural decorative element of the overall building. The colors of corrugated fences are very diverse, which makes it possible to combine it into one ensemble with the roof and facade.

Light colors, as you know, have the property of visually expanding space, while dark colors, on the contrary, reduce it and make it less catchy.

When choosing a profiled sheet for a fence, many people prefer green, as it fits very organically into the landscape design and harmonizes with the background of green spaces. Do not forget that the fence should not stand out from the overall color composition and design of the structure. The most popular and sought-after shades are brown, burgundy, green, blue and gray. They are compatible with almost all facade materials.

Colors such as yellow and red are quite risky to use when decorating a fence - they are too bright and catchy, they are difficult to combine with other shades and can create contrasts.

A fence made of galvanized profiled sheets is noticeably inferior in its characteristics to a painted one. Colored corrugated sheets are beautiful, practical and durable. These factors are decisive in construction and design.

Tips for choosing colors

Of course, the choice of colors for corrugated sheets used in building a house and landscaping a site is a matter of taste and personal preference of the owner. But if you need help, try choosing the right shade based on basic design principles.

In the case of fencing, a win-win solution would be the same color of the fence and the roof of the house. If it is selected for practical reasons - so that a fence located close to the road does not have to be washed frequently, then it is better to choose dark shades of brown, gray, and green.

When you need to fill between massive stone or brick pillars, choose either a shade similar to them, or a contrasting one, but compatible with the color of the supports that you want to visually highlight.

The color of the inside is also important. It is selected in accordance with the style, design and area of ​​the site. If it is small, leave the “native” light shade on the backside - it expands the space. Dark tones will help to visually reduce a large area and give it a more intimate feel. With the help of bright colors it is often possible to enliven the landscape or maintain the modern style of its design.

The roof is more difficult - it must be in harmony with the exterior of the house. Therefore, it is best to make it the same color as the doors, trim, and gutters.

Roof covering

Today, protective and decorative coatings are available in matte and glossy versions, and various color solutions allow you to realize the most daring design ideas.

The most popular colors of roofing sheeting are:

• polyester according to RAL 3005, 5002, 3011 and 9014;
• plastisol according to RAL 1015 and 9010, P 362;
• prism with standard markings 1015, 5005, 305, 7024 and according to RAL Aurora, Helios and Atlantis.

Corrugated roofing can be of any color, but it must be remembered that any building must fit harmoniously into the surrounding space and not create overly bright and contrasting spots. In addition, the color should be practical, despite the fact that the corrugated sheet is very easy to care for. It is enough to wash the product under running water, even without using detergent. However, it is not recommended to use white material for roof cladding. From a practical point of view, it is the least suitable, since dirty stains and dust will be too noticeable on such a coating.

When selecting colored corrugated sheets, you should be guided by a number of rules. The color of the roof is matched to the shade of the façade of the building, and the color of the walls, if there is a roofing covering, is matched to the color of the roof. The color of the roofing should go well with the facade of the building, the color of the windows, pediment, frame and all other elements. In addition, the building must be in harmony with nearby buildings.

In order not to stand out as a bright spot against the general background and at the same time not to get lost among the green spaces, it is necessary to take into account the compatibility of the most popular colors and shades:

• gray color goes well with crimson, lilac and purple;
• red is ideal for all shades of blue, gray and green;
• Beige, dark blue and black look good with burgundy;
• scarlet color harmonizes with light blue and green;
• raspberry - with gray and mauve;
• yellow - with blue, violet, and green;
• blue echoes sandy shades, as well as yellow and orange;
• orange goes harmoniously with pale blue, purple and bright blue;
• purple - with different shades of green;
• brown goes with red, orange and beige tones;
• hot pink - all sorts of shades of blue;
• pale pink - light green, blue and lilac.

Additional painting

In some cases, additional painting of the profiled sheet may be required. The reasons for this may be:

1. Scratches and minor damage that appeared during transportation.
2. Extending the service life of profiled sheets.
3. Need to update faded paint.
4. The desire to change the color for aesthetic reasons or to change the design solution.

There are five painting technologies:

1. Electrostatic - suitable for painting sheets with a slightly corrugated or wavy surface.
2. Powder is one of the most durable. It is heat-resistant: it can withstand from minus 60 to plus 150 degrees, but a heat chamber is required.
3. Pneumatic - characterized by high paint consumption. Suitable for use at home.
4. Airless - great for flat surfaces.

It should be noted that on the monitor screen, when compared with paper media, the color palette of corrugated sheets is slightly different, so preference should be given to lighter tones. It is recommended to use a color compatibility table.

Colored profiled sheet is a modern universal solution for finishing roofs, cladding facades of residential and industrial buildings, erecting fences, etc. It has excellent technical and aesthetic characteristics that will not leave even the most demanding buyer indifferent.

Price overview

The cost of RAL-painted corrugated sheets varies depending on the brand, and the color palette does not affect the price in any way. We suggest considering where you can buy RAL corrugated sheeting, as well as how its price varies depending on the region:

Sales are carried out both in stores of official dealers and at metal depots. If you visit the Chelyabinsk or Klimovsky corrugated sheeting plant, you can save significantly, because The manufacturer always sets a price below the market price.
