Supply of hot dip galvanized steel grating

1, hot dip galvanized steel grating Profile:

hot dip galvanized steel grating is flat according to certain distance and cross-bar arrangement, and welded into the middle of a square lattice with an iron and steel products, hot dip galvanized steel grating
Moderators use to do drain cover, steel platform plate, steel ladder treads. After a twisted bar commonly used square steel, flat steel can also be used to do bar.

2, hot dip galvanized steel grating production standards

hot dip galvanized steel grating manufacturing standards, China YB/T4001.1-2007 standards; addition, the U.S., Britain, Australia and New Zealand have their own standards. Steels by

GB700-88, GB1220-92.

3, hot dip galvanized steel grating production methods:

bonding pressure locked steel grating or hot dip galvanized steel grating antiseptic treatment after hot dip galvanized steel grating is.

4, hot dip galvanized steel grating types

in accordance with the production process can be divided into pressure welding hot dip galvanized steel grating and pressure lock hot dip galvanized steel grating; by load flat steel I-shape can be divided into hot dip galvanized steel grating, serrated Redu
Zinc steel grating and planar-type hot dip galvanized steel grating.

5, hot dip galvanized steel grating plate fixation

welding and installation of optional clip fastening two ways. Welding has the advantage of permanently fixed and will not come loose, the specific location in the grating on each corner of the first root of flat steel, weld length
Not less than 20mm, the high angle of not less than 3mm welding. Installation folder does not destroy the advantages of hot dip galvanized layer and the demolition of convenience, each plate at least 4 sets of installation folder, the installation folder with the use of the number of
The board increases in length. The safest way is not under the folder directly to the screw head welded to the beam to ensure the grating installation folder will not come loose and fall from the beam.

6, flat steel, bar size: 1, flat steel: Material for the Q235A or stainless steel, a common plane type, tooth type and section I slip type. Common specifications are 20 * 5,25 * 5,25 * 3,32 * 5,32 * 5.40 * 5.40 * 3,50 * 5,65 * 5,75 * 6,100 * 8,100 * 10 and so on. 2, bar: Material for the Q235A or 304 stainless steel bar, twisted square steel, square steel or six angles. Twisted square steel plate garden by drawing upon and twisted from side mode, the common specifications are 5 * 5,6 * 6,8 * 8mm and so on.

7, hot dip galvanized steel grating characteristics and uses: 1. characteristics: high strength, light structure: strong bonding grid structure, high bearing, structural lightweight, easy loading and other characteristics; beautiful appearance, durable : hot-dip zinc coating gives very good corrosion resistance, surface gloss appearance; ventilation, lighting, cooling, explosion-proof, non-slip performance; anti-product contamination. 2. Uses: Widely used in petrochemical, power plants, water plants, sewage treatment plants, municipal engineering, environmental engineering and other fields of the platforms, walkways, bridge, ditch cover, covers, ladders, fences, railings.
