1、 Introduction to steel grating: it is a steel product with square grid in the middle, which is made of flat steel and cross bars at a certain distance. The surface is hot-dip galvanized steel grating. The steel grating is made of carbon steel, and the surface hot-dip galvanizing treatment can prevent oxidation. Generally, hot-dip galvanizing treatment is adopted.
2、 Fabrication method of steel grating: according to the specifications given by the customer, the steel grating shall be processed, welded, cut, and then wrapped. If there is a missing corner, the corner shall be removed from the edge.
3、 Type of steel grating: according to the production process, it can be divided into pressure welded steel grating and pressure locked steel grating, and according to the shape of bearing flat steel, it can be divided into I-shaped steel grating, tooth shaped steel grating and plane shaped steel grating.
4、 Fixing method of steel grating: welding and installation clamp fixation can be selected. The advantage of welding is permanent fixation without looseness. The specific position is on each corner root edge steel of steel grating. The weld length is not less than 20mm and the height is not less than 3mm. The advantage of the installation clip is that it does not damage the hot-dip galvanized layer and is easy to disassemble. Each plate requires at least 4 sets of installation clips. The number of installation clips increases with the increase of plate length. The safe method is to directly weld the screw head on the steel beam without using the lower clip to ensure that the steel grating will not slide off the beam due to the looseness of the installation frame.
5、 Representation method of steel grating: the center spacing of flat steel is divided by series: 30 mm for series 1, 40 mm for series 2, 60 mm for series 3, and 50 mm for series 1 and 100 mm for series 2.
6、 Characteristics of steel grating: the firm grid pressure welding structure makes it have the characteristics of high bearing capacity, good structure, easy hoisting, beautiful appearance, durable, hot dip galvanizing surface treatment makes it have a good anti-corrosion capacity, beautiful surface luster, ventilation, lighting, heat dissipation, explosion-proof, good skid resistance, and dirt prevention.
7、 Use of steel grating: it is widely used in platforms, walkways, ditch covers, well covers, ladders, fences, guardrails, etc. in petrochemical industry, power plants, water plants, sewage treatment plants, municipal engineering, sanitation engineering and other fields.
