Compared with the checkered plate and other grille, the Fillinger steel grating has the following advantages:
Material saving: the way to withstand the same load under the conditions of the material. Correspondingly, can reduce the bearing structure of the material.
Reduce investment: saving materials, labor and construction period, free cleaning and maintenance.
Construction is simple: in the pre-installed support with bolts clamping, one person can make the installation.
Save time: the product does not require on-site re-processing, installation is very fast.
Durable: with hot dip zinc corrosion treatment, impact resistance and pressure capacity.
Modern style: beautiful appearance, design specifications, ventilation, giving the overall smooth modern.
Lightweight structure: less material, light structure, and easy to lift.
Anti dirt:: no rain, snow and dust.
Reduce the wind resistance: due to good ventilation, the case of wind and wind resistance is small, reduce wind damage.
Simple design: no small support beam, simple structure, simple design; no need to design steel grating details, only specify the model, the factory can design customers on behalf of the platoon.
Ventilation, lighting, good cooling, explosion-proof, anti-skid performance.

Definition of steel grating
The steel grating is a kind of open-type steel structure which is fixed by welding or press lock by carrying the flat steel and the crossbar according to certain mesh.
grating specification marks
1, Bearing bar center spacing 12.5,15,20,25,30,30.16,32.5,34.3,40,60 mm, etc. 30mm, 40mm recommended .
2, Cross bar spacing 38,50,60,76,100 mm, etc. 50mm, 100mm recommended .
3, Bearing bar shape mark:
F means flat steel (which can be omitted in the mark);
S means serrated;
I represents I-shaped flat steel.
4, surface treatment mark:
G means hot dip galvanized (can be omitted in the mark);
P means paint;
U indicates that the surface is not treated(mill finish).
Glossary
1, Bearing bar-bearing bar bears the main load of flat steel, its direction parallel to steel grating span direction.
2, Bearing bar center distance-center to the center of the distance of adjacent two bearing bars:
3, Cross bar-the twisted bars round bars and flat bars fixed on the flat steel, for the link of the bear bars.
4, Cross bar center distance-center to the center of the distance of adjacent two cross bars:
5, Steel grating length-max dimension parallel to the direction of bearing bars.
6, Steel grating with-max dimension perpendicular to the direction of bearing bars.
steel grating common type
According to the different types of flat steel, steel grating is divided into the following three types, their respective characteristics are as follows:
1, flat type: flat steel grating is one of the most widely used steel grating, mainly used for platforms, walkways, covers, stepping boards and so on.
2, serrated type: Compared with the flat steel grating, serrated grating’s anti-skid effect is better.
3, I shape-type: compared with the flat steel grating. I-shaped steel grating is light weighted, more economical.
Steel grating common specifications
1, Bearing bar spacing of 30mm steel grating is the most widely used with the strongest resistance on the surface impact.
2, Bearing bar spacing of 40mm steel grating si the most economical, the most lightweight type, in the smaller range of span, it’s the most ideal choice.
3, Bearing bar of 60mm with cross bar spacing of 50mm is a type developed for the mining industry. It solves the problem of mineral splashing on the board. It is often designated as a processing plant, a running station, a crushing system surface.

Steel grating installation method
1、 the installation of steel grating can be fixed by welding and clamp fixed. The welding is suitable for permanent no need removal of parts, such as equipment around the platform. And the clamps fixed installation is with no damage to the zinc layer and easy to remove.
2、 welding fixed method is: in the steel grating each corner of the first flat steel, the weld length of not less than 20mm, high not less than 3mm of the fillet weld.
3、 the clamp installation can be applied with a variety of series of steel grating.
4、 the use of clip fixed method is: each plate at least four sets of clips. It is advisable to install larger plates with more clips. When ordering clip, please indicate the type, quantity, and material.
Steel grating installation method
clamps
Type A: consists of a double hook with the upper pressure plate, a toothed under pressure plate and a M8 hexagon bolts.
Type B: consists of an upper platen with double hooks (one of which can be enclosed in two adjacent steel gratings), a toothed under pressure plate and an M8 angled bolt.
Type C: consists of a double hook with a upper pressure and M8 hex head bolts.
Steel grating order guide
1, Ensure steel grating material, flat steel shape, surface treatment.
2, Select the appropriate steel grating model according to the load table.
3, Specify the requirements of banding and opened place.
4, Provide the size and quantity of steel grating, and specify the direction of bearing bar(that is, the direction of the span. The size is usually written in the back, and then add "LB" to distinguish).
5, On a large area of steel grating needed, the layout design is needed. Please provide the following information: all relevant dimensions, support beam position, cross-sectional size, channel opening, moving plate. The location and size of the opening.
6, Steel grating is usually priced per square meter. The area calculation principle is executed according to the YB / T4001-2007 standard, that is, according to the maximum peripheral size. Including openings and notches.
7, The rational distribution of steel grating.
Steel grating area calculation
1, in the absence of drawings, according to the user specified size processing. The area is the actual number of steel gratings multiplied by the sum of the length and the width, which contains the opening and cut portions.
2, to provide drawings on behalf of the user to carry out the layout of the grid layout, the area according to the total size of the drawings on the calculation. It contains openings and cutouts.
3, for shaped steel grating, the area according to the total number of length (L) x width (w) calculation, It contains openings and cutouts.
