Galvanized Metal Bar Grating

Our production company galvanized metal bar grating is located in Arak city. With 5000 square meters produce 5 ton/day grating. With skill full staff and suitable facilities to produce various galvanized metal bar grating with the best quality. The company has no limitations in its production. Also, we produce Grating clamps, which are used to fix the grating in its installation place.

This type of grating has the highest consumption rate which is manufactured without any limitation. All of the company produced gratings have the following standards specifications :

ANSI/NAAMM MBG 531

ANSI/NAAMM MBG 532

BS 4592

DIN 24531

Type of Grating

The type of grating is indicated by a letter,

W  Welded ( steel gratings only )

P  Pressure-locked

R  Riveted

Bearing Bar Spacing

Bearing bar spacing is designed by a number that indicates sixteenths of an inch.

for welded or pressure-locked grating this is the distance, in sixteenths of an inch, center-to-center of bars. For riveted grating is the distance, in sixteenths of an inch, between bearing bar faces.

Cross Bar or Rivet Spacing

Crossbar or rivet spacing is designed by a number that indicates inches. For welded or pressure-locked grating this is the distance, in inches, center-to-center of crossbars. For riveted grating, it is the distance in inches center-to-center of rivets, measured along a single bearing bar.

Size of Bearing Bars

The size of bearing bars is expressed in inches of depth and thickness as follows :

Steel: 3/4*1/8  –  3/4*3/16  –  1*1/8  –  1*3/16  –  1 1/4*1/8  –  1 1/4*3/16

Material

Grating Material is designed by name, such as “steel”, ” Stainless steel” or “Aluminium”.

 Electroforge grating ( resistive welding )

In this type of grating, the carrier and connector are forged together with high voltage and high pressure ( more than 100 tons ).

Stainless Steel grating

This type of grating is manufactured using argon welding and steel sheet 304. This is the most proper option for applications in a hygienic environment and food industries.

Galvanized coating

It is according to ASTM A 123 with a minimum thickness of 80 microns which is passed through all coating tests.
