Fabrications:
The pressed welded steel/bar grating is made of bearing bar and cross rods. They placed horizontally and vertically, and at an equal pitch apart, by welding with 200ton hydraulic resistance automatic welding equipment then cutting punching and handing ends.
Center to Center Bearing Bar Spacing: we usually supply with 30mm or 40mm
Center to Center Cross Bar Spacing: usually supply with 50mm or 100mm. and we are pleased to accept your special order.
Steel/bar grating features:

  1. High strength, light weight
  2. Anticorrosion, durable
  3. Smooth ,bright and attractive
  4. Easy handling and maintains
  5. Good ventilation, lighting, heat-dispersing, resistant to sliding and explosion
  6. Easy installation and disassemble

Steel/bar grating application:
They are widely used for platform, walkway, trestle, covers, ladders and fence in many fields, such as petroleum and chemical, Electric power, water supply, sewage treatment, shipbuilding, parking lot, construction, environmental engineering, and so on.

Center to Center Bearing Bar Spacing
 

Center to center bearing bar spacing is the of distance from the center of one bearing bar to the center of the next bearing bar.

 
Center to Center Cross Bar Spacing
 

Center to center cross bar spacing is the distance from the center of one cross bar to the center of next cross bar.

 
Construction
 

The bearing bars run parallel to the length or span of a standard grating panel and are responsible for the product's load bearing capabilities. The cross bars, which run parallel to the width of the span, are primarily responsible for holding the bearing bars together. However, they also play a factor in deflection characteristics, especially for concentrated loads which are not distributed across the span of the grating.

 
Surface
 

Welded bar grating is available with the following surfaces:
· Smooth - Standard surface.
· Serrated - Serrations are cut into the grating’s bearing bars surface

 
Bearing Bar Height
 

The bearing bar height, also known as bearing bar depth, is measured from the bottom of the bearing bar to the top.

 
Bearing Bar Thickness
 

The bearing bar thickness, also known as bearing bar width, is the measurement of distance between the left surface of the bearing bar to the right surface of the same bearing bar.

 
Span
 

The span of the grating is the length of the grating between grating supports. In order to perform in accordance with its design loading characteristics, grating must be installed so that the bearing bars are parallel to the span. This is necessary because bearing bars are the primary elements which support the load applied to the grating.
