Steel grating welding

Steel grating welding:

There are two kinds of machine pressure welding and manual manufacturing: machine pressure welding uses a high-voltage resistance pressure welding machine. In the flat steel, high-quality steel grating with strong welding points, high stability and strength can be obtained. The hand-made steel grating is first punched on the flat steel, and then the crossbar is placed in the hole for spot welding.

There will be open space between the crossbar and the flat steel, but each contact point can be welded to achieve the same melting connection between the flat steel and the twist steel, so the welding will be stronger and the strength will be improved, but the appearance is not as good as the beautiful folding of pressure welding Modify this paragraph to use pressure welded steel grating for alloys, building materials, power stations, boilers, shipbuilding, petrochemical, chemical and general industrial plants, municipal construction and other occupations.

It has the advantages of ventilation and light transmission, anti-skid, strong bearing capacity, beautiful and durable, easy to clean, and simple installation. Steel grating has been widely used in all walks of life at home and abroad, mainly used as industrial channels, ladder treads, handrails, channel floors, railway bridge sideways, high-altitude tower channels, drain covers, well covers, road barriers, three-dimensional Parking lot, the fence of institutions, campuses, factories, enterprises, sports fields, garden villas.

It can also be used as exterior windows of houses, balcony guardrails, guardrails for highways and railways, etc. As a new type of engineering material, pressure welded steel grating is mainly used for channels, trestle, bridges, highway guardrails, trench covers, gates, gates in the fields of metallurgy, power, marine, municipal, petrochemical, transportation, building materials, national defense, etc. and other equipment. At present, Our country’s annual demand for steel grating is about 270,000 tons. Therefore, the market prospect of pressure welded steel grating is very broad.

Installation of platform steel grating

Before laying and installing the steel grating on the platform, first confirm whether the installation of the overall steel structure meets the design requirements. First, confirm that the location of the steel grating on the platform must be laid according to the elevation and number required by the drawings. The number is seated and accurately positioned.

The laying process of the platform steel grating is as follows:

1. Attention should be paid to the installation of the platform steel grating. Once the platform steel grating is placed on the beam, the gap should be adjusted and fixed immediately to avoid displacement of the platform steel grating and cause safety accidents. The location of the platform steel grating must be laid according to the elevation and number required by the drawings.                        2. The installation gap of the platform steel grating is generally 10mm.

3. Both ends of the loaded flat steel of the platform steel grating must be supported on steel beams or other supporting frames, and the lap length of each end shall not be less than 25mm. The distance between the steel gratings of the two platforms is usually 10mm. During installation, appropriate adjustments should be made according to the requirements of the drawings and the actual situation on site.

4. The installation spacing should meet the following requirements: the spacing between the platform steel gratings is 3mm, and the distance between the platform steel grating and the adjacent structure is 10mm.
