Peculiarities
The manufacturing company SORMAT, which was founded in Finland in 1970, has been one of the leaders in the manufacture of fasteners for a long time. Today she is a leader in her field of activity. In the production process, the company uses only high-quality materials and raw materials, thereby guaranteeing the reliability of its goods.
According to legal regulations, according to the rules of which the product is manufactured, fasteners are characterized by the following technical parameters:
- nominal thread size;
- the length of the fastener;
- the diameter of the hole in the material to be attached;
- tightening torque;
- minimum drilling depth;
- effective depth;
- the maximum thickness of the attached material;
- maximum permissible load.
The most popular are SORMAT chemical anchors, which are characterized by strong adhesion to the base material.
The design of such a product differs from conventional anchors.
- Special adhesive composition.
- A metal fastening insert that consists of a sleeve, a stud and a reinforcing bar. For its manufacture, galvanized and stainless steel is used, the strength of which can be different.
As for the adhesive composition, its exact formula is known only to the manufacturer. Components:
- artificial resin based on polyurethane, acrylic and polyester;
- the binder mixture, in most cases, is quartz sand;
- filler - cement is used, since this material provides high strength of the composition;
- hardener.
This type of fastener has a number of advantages and features.
- High strength.
- Sealed connection between fasteners and base material.
- Ease of installation.
- The installation of the anchor does not provoke tensile stresses in the concrete.
- High load-bearing capacity.
- Suitable for various industries.
- The composition used for fixing has excellent chemical, corrosive and weather resistance properties.
- A variety of products for their intended purpose. There are models that can be installed even on a damp surface and under water.
- Long service life. For 50 years, the product has not lost its original properties.
- The adhesive does not contain toxic components, so it is completely safe for the person who is installing.
- Using this type of fastener, you can connect a part or structure to any surface: concrete, stone, wood, brick.
If we talk about the shortcomings, then it is worth noting the high cost, the limited shelf life of the adhesive composition after opening, the hardening period of the composition, depending on the temperature regime.
How to choose?
When choosing a fastening element such as the SORMAT anchor, several very important criteria must be taken into account:
- physical and technical parameters;
- properties;
- the conditions under which the product will be mounted and operated;
- what material will be attached to;
- type of product;
- temperature range of humidity;
- type of adhesive;
- solidification rate.
In the event that you buy fasteners from a dealer, be sure to make sure that it is legally valid. Proof of this is the availability of quality certificates for products and a document confirming the legality of dealer activities.

Applications
Excellent physical and technical parameters, which are characteristic of SORMAT anchors, make it possible to use fasteners in various fields of activity, both in production and in everyday life. They are applied in the process:
- installation of elements of road structures, such as barriers, noise screens, curbs, lighting poles;
- installation of a ventilated facade, if the basis of the walls is aerated concrete;
- installation of a massive structure - columns, building canopy, molded parts;
- installation of an advertising banner, billboard, banner;
- fastening flights of stairs;
- production and installation of elevator shafts, escalators;
- reconstruction of lift shafts;
- installation of scaffolding.
Also, very often, this fastener is used during the restoration of historical buildings and structures, strengthening the foundation, building berths, ski slopes and lifts.
SORMAT products are an indispensable fastening element for the installation of high-voltage power lines.
Installation of the anchor is also not very difficult and does not require certain knowledge and skills. All that is needed is to strictly and clearly follow the instructions for use, which must be attached to the product.
Range
In addition to special chemical ones, SORMAT also manufactures these types of anchor bolts for high loads.
- Wedge. Such anchors are used in the process of fastening elements in stretched and compressed concrete zones, in natural stone foundations and in solid clay bricks. With their help, steel structures, base plates, enclosing structures, handrails, staircases, and building facade systems are mounted. Manufactured from hot-dip galvanized steel. It can be mounted both in dry rooms and in high humidity conditions. The fasteners guarantee a reliable, sealed connection.
- Nylon. The product has high technical characteristics: strength, wear resistance, durability. Suitable for fixing structures to hollow slabs, natural stone, solid clay bricks, compressed concrete. Nylon anchor is used in the process of installing window and door openings, piping, electrical installations, ventilation and air conditioning systems.
- Driving. This is one of the most common and frequently used types of anchors. It is characterized by reliable and rigid bonding to any type of base. Possesses high corrosion resistance. It is used to fix ventilation pipes, water pipelines, cable gutters, sprinkler systems, and suspended ceilings.
Each of the above types of SORMAT anchors is available in different sizes. Most often, but this, of course, depends on the scope of application, anchors M8, M10, M16, M20 are used.
