How to fasten slate to iron

Slate and iron are two sturdy and well-liked options for roofing materials. Slate is frequently chosen for its visual appeal and resistance to weathering because of its longevity and natural beauty. Contrarily, iron gives roofing frameworks structural stability and strength. In order to ensure longevity and functionality when combining these two materials, careful consideration of fastening techniques is necessary.

Slate to iron fastening is the process of firmly attaching slate tiles or shingles to an iron framework using specialized techniques. In contrast to conventional wooden or concrete roofs, which are easily fastened with nails or screws, iron roofs require different fastening techniques because of the hardness and composition of the material. Slate tiles that are properly fastened will stay firmly in place even in the face of weather-related factors like wind, rain, or snow.

Slate is frequently attached to iron using screws or nails made especially for metal roofing. To avoid rust and guarantee longevity, these fasteners are usually composed of materials that are resistant to corrosion, such as galvanized or stainless steel. Their purpose is to firmly fasten the slate tiles to the iron framework underneath by penetrating them without causing any harm.

It’s important to properly prep the surface before attaching slate to iron. This includes making certain that the iron framework is free of corrosion and rust, which could eventually weaken the fastening points. It is also possible to improve the roof’s functional performance and aesthetic appeal by precisely aligning and arranging the slate tiles.

What is slate

Many kinds of roofing materials have more than one name at the moment. One item can be categorized as folk, while the other satisfies legal requirements. As a result, each kind of slate has a unique attachment technology.

Table: Slate Varieties

The table indicates that roofers cannot agree on which materials belong in the slate category and which does not. In this context, we will look at ways to fasten each of the roofing materials on the list.

What applies to the iron

Furthermore, there is no agreement on this issue. Steel rails, stainless alloy rifles, formed rentals, and profiled galvanized metal profiles are some names for iron. The slate fastening method is chosen after accounting for the individual physical parameters of each of the materials on the list. While some techniques can be applied when screwing slate to thin galvanized profiles, a totally different technology is needed when screwing slate to thick metal beams.

A steel corner pattern or square and round pipework can serve as an iron slate frame.

Schifer mount to galvanized profiles

This choice is available when using a metal slate to line the wall. Because the galvanized profile has a thickness of less than 0.5 mm, special metal screws can be used to secure it. They are offered for sale with metal slate, or metal profiles. Since the material is light, thin galvanized metal profiles can support it without experiencing any issues. Cement-sand solutions take a lot longer to decorate walls. Regarding longevity, everything hinges on adherence to operating guidelines.

A frame or crate can be installed from a galvanized profile if a metal slate is chosen for the casing.

Metal slate has just started to be utilized in the process of building prefabricated metal structures out of profiles. These are structures with specific operating parameters; slate fastening can be achieved by bolts or self-tapping screws into holes that have been previously prepared, depending on the location.

The most practical way to fasten a metal slate to a galvanized profile is using unique self-tapping screws designed for profiled sheets.

Vital. Rubber gaskets for sealing holes as a roofing coating should be used in all versions when using metal sheets. It is not possible to seal the opening when building a fence using slate.

When you need to screw the slate to the gland

In three cases, slate is attached to the gland.

    During the roof covering. Tthe roofs are currently found often, and not only on private buildings. Most often, a professionalist (metal slate) is attached to the metal frame, the main task of the coating is to provide protection against precipitation. For fixation, special screws for metal with rubber gasket are used. Metal structures to other types of roofing materials from all points of view are impractical.

Hangars, garages, and other technical rooms are frequently used to create metal frames for corrugated board casing.

When installing fences and other types of fencing, the Schifer is typically fastened to the iron.

Slate sheathing of the iron frame is a typical choice for industrial structures.

A polycarbonate slate may also be utilized in each of these situations, but only if there will be little stress on the structures.

What metizes are used to fasten the skin

There are various ways to fasten elements, depending on the specifications of the metal and slate.

Self -tapping screws

The most well-known and frequently utilized method for fastening the metal slate to the profile frame. Self-tapping screws come with a unique drill at the end that is used to drill a hole in slate and rental materials.

Corrugated board fastened with metal screws

Benefits of this technology include:

  • The speed of work. Self -cut through the metal simultaneously drilles symmetrical holes in two connected surfaces, there is no need to make markings, separately drill holes, combine and check them;
  • reliability. Self -tapping screws are made of alloy carbon instrumental steels, physical characteristics guarantee the strength of fastening. To protect external surfaces from corrosion processes, they are covered with a zinc layer with a thickness of at least 12 microns;
  • Universality of use. The method provides complete tightness of the roof, regardless of the angle of inclination of slopes. Can be applied both on flat and on complex scatter roofs. Self -tapping screws can be fixed with metal fences, sheets of facade walls, etc. D.;
  • The possibility of dismantling. This is a detachable connection, if necessary, the design is dismantled and assembled in a new place.

Self-tapping screws for roofing have excellent operational qualities.

Bollet compounds

Used to secure large slate sheets with asbestos cement that is both flat and wavy. It is only advised to use this mounting technique when making fences. The roof will inevitably leak because the slate’s holes cannot be properly sealed. Prior to connecting, you must precisely mark and drill holes through the slate and metal.

Schifer fastening to the gland using bolts works better in vertical planes where the structure’s tightness is not as critical.

Vital. Pulling bolts is strictly forbidden; asbestos-cement slate does not differ in high strength indicators. Furthermore, you ought to account for temperature expansion at all times.


Today’s implementation tools enable the installation of rivets up to 4 mm in diameter, allowing the combination of heavy components into a single, sturdy structure. Using pneumatic or manual tools, rivets are easy to install and don’t require specialized training.

Exhaust rivets can be used to fasten metal slate to metal.

Screwing technology with self -tapping screws

To ensure a robust and long-lasting slate-to-metal connection, it is recommended that experienced roofers follow construction standards and regulations and follow their recommendations. Which ones?

    The angle between the screw and the metal should be 90 °. This is necessary for several reasons. Firstly, otherwise the end of the drill will slide along the surface of the slate, it will be very difficult to start drilling. Such slipping is damaged by anti -corrosion coatings, which has an extremely negative effect on the durability of the coating. Secondly, at the junction site, the elastic band will not be able to ensure tightness. She will closely close the hole, in addition, from the side of strong compression, cracks will necessarily appear over time.

Regardless of the kind of slate, self-cutting is always screwed at a right angle to the sheet’s surface.

The self-cut drill must unavoidably be thicker than the materials that are fastened.

The weight of the materials being fastened determines the fastener dimensions.

Sensible guidance. Drilling holes through the metal takes a lot of work. Make the ultimate choice only after evaluating your physical capabilities.

Find out how to accomplish a dependable attachment that endures the weather without sacrificing the visual appeal of your slate roofing.

Technology for fixing rivets

These peculiar compounds are limited to use on vertical structures, such as fences, walls, etc. D. Holes are drilled along the previously determined points prior to the connection in the details.

Make rivet holes.

Two doses of connection delay are experienced. The rivet expands and becomes fixed in the hole after the handle is initially pressed. The final tightening of the components and the separation of the excess part take place during the second pressing on the handles.

Put the fasteners in place, then join the components with the rivet.

Sensible guidance. The rivet length must be carefully chosen; it can be found using the formula C = A+B. The rivet’s length is denoted by C, its diameter by a, and the total thickness of the linked elements by B.

Using a pneumatic tool is preferable if you need to insert a lot of rivets. It is best to purchase high-quality rivets because Chinese rivets break easily and are difficult to cut off.

Using a pneumatic tool is more convenient when there is a lot of work involved.

Tools Needed Hammer, nails, drill, screws
Steps 1. Place slate over iron roof. 2. Use hammer to gently tap nails into slate and iron, ensuring secure fit. 3. Alternatively, use drill to make holes in slate and iron, then insert screws for stronger hold.

Slate must be fastened to iron roofs with extreme precision, using the right tools and materials. Starting with a strong foundation is crucial to guaranteeing a secure installation. This usually entails cleaning the roof surface thoroughly and making sure there are no obstructions or debris that could cause problems during installation.

Selecting the appropriate fasteners comes next after the roof surface is ready. Because they are long-lasting and corrosion-resistant, stainless steel nails or screws are frequently suggested for securing slate to an iron roof. These fasteners ought to be long enough and thick enough to hold the slate firmly in place, especially in light of the potentially severe weather that roofs experience.

An additional crucial element in the installation process is the placement of the slate tiles. Slate tiles need to be carefully positioned to guarantee that they overlap and line up with neighboring tiles. This contributes to the overall structural integrity of the roof in addition to improving its aesthetic appeal.

Finally, for long-term performance, sealing and finishing the installation are critical. When necessary, sealants or adhesives made especially for slate roofs can be applied to stop water intrusion and improve the roof’s resistance to different weather conditions. Frequent upkeep, such as inspections and small repairs, can help the roof last longer and continue to provide the building with effective protection.
