Assembly work involves performing a number of tasks aimed at mechanical interference with the work surface. Of course, this requires the use of a number of tools, the replacement of which results in a loss of valuable time, and consequently an increase in the cost value in terms of man-hours. The use of a concrete and steel nailer significantly shortens the time of task completion, increasing efficiency and the level of competitiveness. What is a concrete nailer?

How much does a concrete setting tool speed up work?
Due to the lack of need to use other tools and limiting the necessary activities to a minimum (e.g. elimination of drilling in the work surface), the concrete setting tool speeds up work even ten times! The concrete setting tool is used in direct assembly work, consisting of fastening construction elements using steel fasteners (nails, threaded pins), applied directly to the interior of the concrete or even steel material.
Due to their ease of use, versatility, affordability and availability, the most popular nailers used in assembly work are gas nailers. A concrete nailer allows for quick assembly of partition walls, suspended ceilings to concrete, and also significantly facilitates the installation of heating or electrical installations. The advantage of this type of nailer is the possibility of carrying out work in a serial manner. The concrete connector is inserted without the need to change tools, even when using steel washers, necessary during the installation of e.g. membrane mesh.
Gas nailers drive nails up to 40 mm long into surfaces made of concrete, solid ceramic and silicate bricks and steel. What makes gas nailers practical is the automation of the gas collection process from the container and the analogous application of nails from the magazine. The average efficiency of one gas container is 600 shots, which should allow for the execution of an outline in a facility with an area of 150 m². Gas nailers are characterized by low noise emission and do not generate dust, which means that they can be used during maintenance work in buildings in active use.
What to consider when choosing concrete setting tools?
The selection of the appropriate nailer should take into account the parameters useful in the operation of the device. Their optimal selection will allow for the versatile use of the nailer regardless of the working surface and the scope of work performed. If the elements fixed in concrete are exposed to frequent vibrations or shocks, it may be necessary to use nailers with greater strength to maintain their stability.
Concrete setting tool material can affect their strength and corrosion resistance. Stainless steel is stronger than carbon steel, and galvanized steel has good corrosion resistance. For impact nailers, load capacities are typically 50 kg to 500 kg, but can be much higher for professional applications. Chemical nailers are available in a variety of strength classes that can be tailored to the specific task.
How to choose the right nail length for a concrete nailer?
The nail, when passing through the concrete, must make a hole for the pin, simultaneously breaking and compacting the concrete. At the same time, the concrete fastener should be resistant to the force of impact on hard aggregate.
The minimum nail length should be greater than the thickness of the material being fastened to the concrete. For example, if you are fastening a 5 cm thick wooden beam, the minimum nail length should be at least 7-8 cm. If there is an additional insulating layer on the material being fastened to the concrete, such as wood or plastic, add its thickness to the minimum nail length.
If the element is loaded, the nail length should be increased to ensure adequate load-bearing capacity and stability. For example, when fastening a heavy shelf, it is worth choosing longer nails. The ability of the fastener to penetrate and compact the concrete guarantees optimal indicators of correct fastenings, as well as high values of holding forces.
RAWLPLUG concrete setting tool at the Onninen wholesaler
An excellent example of equipment that meets the highest technical requirements is the Rawlplug R-RAWL-SC40II-SET1 concrete and steel nailer , from the world-renowned RAWLPLUG brand. A wide range of nails from 15 to 38 mm ensures versatility, while the precision of assembly is ensured by the keyless adjustment of the setting depth.
The 30-nail magazine reduces downtime. Additionally, the work is made easier by loading the magazine from the rear and the easy disassembly mechanism. Thanks to this, the operator can quickly unblock or clean the barrel of the nailer. The optimization of working time is supported by the charge indicator and the low weight of the device, allowing for longer work cycles.
