Why steel gratings and what are the benefits of mesh gratings?
Nowadays life sets the fast pace of construction and makes increased demands on structural materials for the construction of buildings and structures for various purposes. Considering the pace, scale and needs of the modern world, we observe the constant development and popularity of construction with the use of metal structures. Since materials for steel construction should be durable, reliable, inexpensive and relatively lightweight, mesh grating is increasingly used in industrial building and civil architecture.
Steel grating – is an advanced structural material used in construction as a covering for service platforms, walkways, galleries, ladders, as well as in the manufacture of various staircases. In addition, it is widely used as fencing elements, in storage rack systems, surface drainage systems, etc. Steel grating is highly resistant to adverse weather conditions and physical impact, making it a versatile material for both indoor and outdoor applications. Due to its design features, steel grating provides high load-bearing capacity combined with its lightweight features, which makes it an essential material is compared to the main competitors - expanded and corrugated steel sheets. The material demonstrates excellent physical and mechanical properties, which allows for its using in all cases when other products are not able to ensure the proper reliability and safety of the structure.
Steel grating first appeared in the middle of the 20th century almost simultaneously in Europe and the USA. On the territory of the former USSR there were only two lines for the production of steel grating, in Magnitogorsk and Bataysk (Russia). The material was called “VISP Grating” or “Bataysky” grating (after the name of the city of production). The indicated grating was produced according to ТУ 36-2370-82 only in a welded version. However, after the collapse of the Soviet Union, both lines ceased functioning.
In Europe and Ukraine steel grating is produced in accordance with DIN 24531-1, DIN 24537-1, RAL GZ-638, which ensures high quality products of the European level and ensures safe movement at industrial and civil construction sites.
Initially, mesh grating was used mainly in the heavy and chemical industries for the organization of passages, service areas and their fencing. However, welded gratings soon began to be used almost everywhere based on the ideas of architects, developers and designers. Therefore, it is not surprising that today steel grating can be seen on modern elevators, oil refineries, car washes, facades and entrance spaces of malls or as decorative elements.
According to manufacturing technology mesh grating can be of two types – welded steel grating (SP) and press-locked steel grating (PR). Detailed information about the difference and advantages of each of these types of grating is given in the corresponding sections of our website.
Main elements of the grating are bearing strips connected by transverse rods and form a mesh structure. Such a structure of welded and press-locked steel grating provides for an easy and quick installation of the grating even in hard-to-reach places, because the grating offers various types of fasteners and fixings. It is the convenience and versatility during installation that allows for construction of complex industrial facilities in a relatively short time. Let's take a closer look at the terminology and parameters of steel grating:
bearing strip - vertically arranged steel strips that take the main load. Bearing strips are located parallel to each other at a distance from support to support.
transverse bar - twisted bar passing across bearing strips, which connects bearing strips to each other with the help of forge-and-press welding method.
banding - a flat bar welded to the ends of strips. The height of banding is usually equal to the height of bearing strip. More information about the types of banding is given in the "Technical Reference" section.
The main advantages of grating over the analogues:
- High load-carrying capacity;
- Lightweight material;
- No need for additional support structures;
- Installation without the use of welding;
- Wide assortment that allows choosing the optimal grating for any conditions of use;
- The price of 1 m2 of steel grating does not exceed the price of analogs with significantly better characteristics
