Snow ladder 155 mm
The snow grille is a key component of the roof snow protection system, which is designed to prevent snow from sliding off, thereby protecting the building's surroundings. This grating is an effective protection against avalanches of snow that may fall from the roof. Its main function is to ensure the safety of pedestrians, building occupants and to protect vehicles from damage caused by snow.
Our snow grating is constructed from hot-dip galvanized steel angles with a frame size of 20 x 20 x 2 mm. This material was chosen for its corrosion resistance, which ensures a long life of the grating even in harsh weather conditions. The bars of the grating are also made of 20 x 1 mm hot-dip galvanized steel sheet, which ensures the strength and stability of the entire structure.
This design of snow barrier not only meets the requirements for safety and security, but is also cost-effective due to its long life and weather resistance.
Material
Hot-dip galvanized steel profile; available in natural (unpainted) or powder-coated finish. Fasteners in non-standard colors available upon request (for an additional fee, lead time up to 7 days).
Dimensions
- Length: 2000/3000* mm (*on individual order)
- Height: 155 mm
- Grid thickness: 20 x 20 x 2 mm
- Distance between bars: 110 mm
Installation on all types of roofing
Our snow fences can be mounted on any type of roofing. With our wide range of products, we have a product that can be mounted on any type of roofing. No matter what material your roof is made of, we can provide the right solution for your needs. Snow fences provide safety and protect your roof from snow and ice damage. We offer a variety of models and colors to match the look of your roof. Snow fences are available in two heights: 155 mm and 200 mm.
Zinc coating
All elements are made of steel that has undergone a tinning process. This is the most effective and durable way to protect steel from corrosion. During the tinning process, zinc atoms penetrate the outer layer of the steel, forming a surface alloy of iron and zinc, which forms a protective layer against corrosion. The durability of zinc coatings can reach up to 100 years, depending on conditions.
Powder coating
Powder coating is resistant to corrosion, chemicals, high temperatures and mechanical damage. Electrically charged powder paint particles are applied to the metal surface, which is then heated to 140-200°C, causing the powder to melt and polymerize. The advantages of powder coating include a smooth, crack- and stain-free surface, anti-corrosion properties, resistance to mechanical damage, thermal and chemical resistance, and environmental friendliness.
Snow balustrade: and the number of handles needed
What does the number of handles depend on?
- The slope of the roof (the steeper the slope, the more handles)
- the length of the roof surface (rafters) - above 6 m, an increase in the number of handles or even the installation of a second row of railings is required
- for standard lengths of rafters, the number of handles is used according to the table below
Note - exceptions!
- When the roof pitch exceeds 55° - always add one bracket to the set.
- When the length of the rafters exceeds 6 m, it is necessary to add 1 bracket for every 2 m of rafters above 7 m. Thus, from 6 m to 8 m - one additional bracket, from 8 m to 10 m - two additional brackets.
- Above 10 m, it is necessary to use an additional row of handrails - about 4 m above the first row. In this case, the lower handrail is installed according to the table above, and the upper handrail according to point 2
- In the case of handrails with a height of 20 cm, an additional bracket should be used.
Note: The above information is the result of collected information and our experience. The above information should not be considered as installation instructions. The use of roof communication should be in accordance with the technical design drawn up for the building, taking into account the requirements of relevant standards and applicable technical and construction regulations. To add additional brackets to the kit, use the menu of individual components.

General assembly rules
The method of mounting the handrail to the bracket:
Special slats on the bracket allow quick and easy installation of the snow railing. Simply push the handrail profile into the latches - the new method of attaching the handrail to the latch brackets is extremely durable. No additional tools are required.
Handrail mounting height:
When installed, the handrail is 65 mm above the base of the latch. For coverings with a module height exceeding 65 mm, installation will not be possible. This applies in particular to:
- metal sheets with a wave height <65 mm
- trapezoidal sheets with a module <65 mm (T-65 profile)
- corrugated sheets with a wave height <65 mm.
Instructions for installation of snow protection:
- Snow guard brackets should be fixed to the wooden roof structure with wood screws in accordance with PN-EN 14592+A1:2012.
- The recommended mounting point for the first row of rails is at the height of the roof trusses
- Edge brackets should be installed so that they are close to the edge of the railing.
Note: The spacing of the brackets, the number of fixing screws and their dimensions should be determined in the technical design, depending on the slope of the roof and the snow load zone, taking into account the load capacity of the elements of about 2 kN.
Screws 6 mm x 60 mm for attaching brackets to the roof surface can be found here: Screws for fixing the snow guard
