grating: What is this, STO, GUEST, dimensions, kinds, application

Grating is a structure made of load-bearing and covering steel strips, which are interconnected in a certain configuration. Grating has many advantages, such as high strength, wear resistance, ease of installation and aesthetic appearance. Grating is widely used in various industries, such as construction, architecture, industry and landscaping. Grating can be made in different ways: pressing or welding.

Pressed flooring is made from low-carbon or stainless steel by cold pressing of connecting strips into the load-bearing ones. This method ensures weldless connection of strips and high strength of joints. Pressed flooring is suitable for use under high loads and aggressive environments.

Welded flooring is produced by contact welding of load-bearing strips with a cover rod of various sections. The main load here is carried by metal strips, and transverse twisted rods perform a connecting function. Welded flooring has high light transmittance and provides good slip protection.

The grating can have different cell shapes, sizes and thickness of strips. Depending on this, the grating can be adapted to different requirements and operating conditions.. The grating can be painted in any color or coated with special protective compounds.

Grid flooring is used for the construction of load-bearing structures of buildings, construction and observation platforms, various fences, overpasses, pedestrian paths, floors for wiping feet and other purposes. Grated flooring has a number of advantages over other types of flooring:

• provides good ventilation and lighting;
• corrosion resistant, moisture, temperature changes;
• easy to install and dismantle;
• economical and durable;
• safe for the environment.

Grating is a modern and reliable material, which can satisfy a variety of needs and tasks. Grating is the choice of professionals!

History of gratings

Grating is a modern and reliable material, which has a long and interesting history. The first prototypes of gratings appeared in ancient times, when people used gratings made of branches or vines to strengthen roads, bridges and fences. In the Middle Ages, bars made of wood or metal were used to protect windows, doors and fireplaces. IN 18-19 Over the centuries, gratings have become widely used in industry, especially in the railway and shipbuilding sectors, where he provided strength, lightness and ventilation of structures.

IN 1949 year, the German company Lichtgitter GmbH launched Europe's first line for the production of welded grating SP. Later 11 years Meiser company, which recently appeared on the market in West Germany, opened a production line for both welded, and pressed grating SP and P. IN THE USSR, where industry developed rapidly, back in the 30s of the last century, an order was issued on the development of grating flooring “Letter of the USSR State Construction Committee from 9 September 1930 g. No AB-4631-2/3 “On the use of welded gratings of the “Bataysk” type and the “VISP” type (welded decking with high structural strength), however, due to the Second World War, the start of production was delayed and only at the end of the 70s, together with the institutes of welding production in Kiev and Leningrad, the project on the use of welded gratings of the Bataysk type and the VISP type was improved and the first lines were launched in. Bataysk and g. Magnitogorsk. In the Soviet Union, welded gratings of the “Bataysk” type and the “VISP” type were called “grid gratings” or “grid flooring”. Nowadays gratings are manufactured according to different standards., such as DIN 24537-1, RAL GZ 638 and IN THAT 1461, which determine its size, form, thickness, coating and other characteristics.

STO gratings

STO grating is an abbreviation fortechnical support systemsgrating. This is a set of documents, which regulate production requirements, quality, safety and use of gratings. STO for gratings are developed and approved by manufacturers or customers of gratings in accordance with regulatory documents, such as GOST, TU, DIN and others.

STO gratings contain information about the types and sizes of gratings, technical specifications, control methods, acceptance rules, transportation and storage, instructions for use and manufacturer's warranties. Grating stations help ensure high quality and reliable gratings, and also protect the interests of consumers.

For example, STO 23083253-002-2017 "Welded grating flooring SP. Technical Specifications" is one of the operating service stations for gratings. It covers welded grating grating SP, which is used as structural elements for maintenance areas, floor gratings, industrial floors, walkways, overpasses, steel structures in various industries and civil engineering, which operate in different climate zones. This document was developed and approved by Firm SOLID CJSC based on DIN 24537-1, FROM 24531-1, RAL GZ 638 and IN THAT 1461.

GOST grating

GOST grating is a state standard, which defines the technical requirements and production conditions, quality, safety and use of gratings. GOST for grating helps ensure a high level of product, as well as protect the interests of consumers and producers. GOST gratings also take into account international standards, which operate in different countries.

For example, one of the current GOST gratings is GOST 23120-78 "Marching stairs, steel platforms and fencing. Technical specifications". This document applies to flight stairs, steel platforms and fences, which are made of cold-formed and hot-rolled profiles. It establishes technical requirements for flight stairs, having an angle of inclination 45 and 60°, as well as rectangular transition platforms.

Another example is GOST 14918-80 “Galvanized thin sheet steel with continuous lines. Technical specifications". This document defines the technical conditions for the production of galvanized sheet steel from continuous lines, which is used for the production of gratings. It sets technical level indicators, which meet the requirements of the highest and first quality categories.

Grating dimensions

The dimensions of the grating depend on the type, method of manufacturing and using flooring. There are two main types of gratings: pressed and welded. Pressed flooring is made from low-carbon or stainless steel by cold pressing of tie strips into load-bearing strips. Welded flooring is produced by resistance welding of load-bearing strips with a cover rod of various sections.

The dimensions of the grating are determined by the following parameters:

• Carrier strip pitch (a) — the distance between the centers of adjacent bearing strips, which bear the main load.
• Cover element pitch (b) — the distance between the centers of adjacent covering elements, which perform a connecting function.
• Carrier strip height (h) - vertical size of the carrier strip.
• Carrier strip thickness (g) — horizontal size of the carrier strip.
• Deck width (B) — horizontal size of the flooring along the covering element.
• Deck length (L) — horizontal dimension of the flooring along the supporting strip.

Depending on these parameters, grating can have different cell shapes, sizes and thickness of strips. The table below shows some examples of grating sizes by type and manufacturing method.
