Platform grating in plant.

The Classification Of Platform Steel Grille

1. According to the welding method, it can be divided into: pressure welding type platform steel grid plate, embedded type platform steel grid plate, lock type platform steel grid plate and through welding type platform steel grid plate. 2. According to the shape of the side surface of the load flat steel, it can be divided into: plane steel plate, tooth steel plate and "work" type steel plate, etc. 3. According to its use, it can be divided into: general purpose steel plate and special purpose steel plate, such as: gutter cover plate, step plate and so on. 4. According to the load flat steel distance: two adjacent center distance of load flat steel, commonly used 30MM, 40MM and 60MM three. 5. According to the bar spacing: the center spacing of two adjacent bar is usually 50MM, 100MM, two kinds.

The Characteristics Of The Platform Steel Grid

1. Can be welded around the kick plate (baffle plate), pattern plate guard plate, installation of connectors and other accessories. 2. Use flat steel with different specifications from the flat steel, or use Angle steel, channel steel, square pipe, etc. 3. Handle and hinge can be installed on the steel plate of the platform that needs to be moved or opened frequently. 4. The welding standard for the edge of the platform steel grille is: one weld for every five parts of series 1; Series 2 every four welding one; Series 3 one weld every three. The weld is not less than 3mm single side fillet welding, the weld length is 20mm.

Platform Steel Grating Specifications

1. The steel plate with 30mm flat steel spacing is the most widely used variety in the industrial field. In the commonly used steel grille series, it has the strongest resistance to surface impact. 2. The steel plate with 40mm flat steel spacing is the most economical and portable variety. In the minimum span of the occasion, is the most ideal choice. 3. Steel plate with flat steel spacing of 60mm and crossbar spacing of 50mm is developed specially for the application of mining industry. It solves the problem of mineral sputtering on the plate surface, which is often designated for the processing plant, transfer station and the plate surface of crushing system in mining industry.

Platform Steel Grating Material

1. Flat steel and bar are made of GB/T700 Q235, according to user requirements, can also be made of other materials. 2. Flat steel adopts hot rolled flat steel or longitudinal shear hot rolled or cold rolled steel strip. 3. The allowable deviation of flat steel size shall comply with the provisions of Table I YB/T4001.1-2007. 4. Toothed flat steel adopts hot rolled flat steel or hot rolled or cold rolled steel strip after longitudinal shear and punching teeth. The tooth size shall not be less than 5 teeth per 100mm. 5. I-shaped flat steel section size and section moment of inertia.

Platform Steel Grating Application

Widely used in chemical, electric power, tap water, sewage treatment, port terminals, building modification, shipbuilding, self-walking parking lot, municipal engineering, sanitation engineering and other fields of platform, walkway, trestle, trench cover, manhole cover, ladder, fence, etc. Beautiful style, easy to install, is a new type of building products.
