1. Serrated I bar steel gratings Brief Introduction

There are mainly four types bearing bars as belowing which are frequently used for steel gratings.

Here we mainly introduce the I bar Gratings. Same as normal bearing bars, there are two type of the I bars, plain type I bar and serrated type I bar. The main advantage of I bar steel grating is it is with high strength – to- weight ratio.

And the belowing info is for normal steel gratings which is as per Webforge's standards. 

A325MSG is the steel grating specifications described as per Australia Standard. A325MSG is same as steel gratings G325/30/100SG. It is regular type in Chinese Market, and it can be electro-forged by Machine directly.

"A"  means A pattern in Australia Standard, mesh size 30x100mm, bearing bar pitch 30mm, cross bar pitch 100mm; 

"325" means bearing bar size is 32x5mm;

"M" means mild steel

"S" means the bearing bar top surface is serrated type

"G" means the steel grating surface treatment is galvanized.

2.Serrated I bar steel gratings Surface Treatment

1) Hot dip galvanized as per ASTM A123 or EN ISO 1461 or special requirement

2) Painted or Powder Coated

3) HDG plus painted/powder coated
