The press welded steel granting, requested by the customers, is made of load flat steel bar and cross bars, placed horizontally and vertically, and at an equal pitch apart, by welding with ***-ton hydraulic resistance automatic welding equipment, then cutting, punching and banding ends.

Load bearing steel bar pitch: Pitch between the two neighboring load bearing steel bars is *0mm or *0mm.

Cross bar pitch: Pitch between two neighboring cross bars is usually *0mm or **0mm. Special specifications can be done according to your request.


Note:

1. Bearing bar pitches may be *5 to *0,*5,*0,*3,*5,*8,*0,*0,*0,*0,*0mm,of which *5,*0,*5 and *0mm are recommended.
2. Cross bar pitches may be *****0mm,of which *0mm,*6mm and **0mm are recommended.
3. Sign of the shape of bearing bars.

F-Plain style (may be omitted in the symbol of steel grating)

S-Serrated style

I-I-section style

4、Sign of surface-treatment

G-Hot galvanizing (may be omitted in the symbol of steel grating)

P-Painted

U-Untreated

1. Characteristics of The Product

They are widely used for platform, trestles, covers, ladders and fencing in many fields such as petroleum and chemical industry, electric power, water supply, sewage treatment, ship building, parking lots, city construction, environmental engineering.
 

1. Manufacturing Process

Steel grating have been fabricated strictly in accordance to the product quality standards, and their high quality is guaranteed under the control of ISO***1 quality system. The manufacturing process charts are as follows:
 

1. Classified By The Type of Load Bearing Flat Steel Bar

 

1. Classified By The Type of Surface Covering Plate

Composite steel grating is made of the steel grating with spanning ability and the checkered plate covering the surface, it comprises of any type steel gratings and various checkered plates.

1. Surface Process of Gratings
2. Hot-dipped galvanizing

Normally, hot-dipped galvanizing will be carried out after end welding process. When the thickness of bearing bars is not less than 5mm,the weight of average Zinc Layer will not be less than **0g/m^2.When the thickness of bearing bars is less than 5mm,the weight of average Zinc Layer will not be less than **0g/m^2.The quality and requirements after hot-dipped galvanizing are according to the standards of GB/T****2

2、 Lacquering

Gain protection layer through the ways of spraying, brushing and soaking.

3、Electro Galvanizing
