Electro Forged Grating

Electro Forged Grating

Operational since 2010, First Electro Forged Grating plant in Northern India. With an in-depth experience in the steel fabrication for over two decades and looking at the industrial requirement, Cell Com felt the need to improve upon the conventional manually fabricated gratings. Cell Com manufactures high quality and economical gratings in a wide range using the state of the art technology of Electro-forging.

Why Electro Forged Grating

  • Custom Manufacturing
  • No crack or open joint & defect free forge welds (without any air gaps)
  • Retains strength of bearing bar
  • Improves slip resistance
  • Visually attractive

Serrated Grating

Types Of Steel Gtatings

Gratings are manufactured in various mesh sizes as per EIL or customer specifications. The Electro-forging machine has the capacity of welding bearing bars of 25x3 mm - 50x8mm and cross bars from 6 mm to 10 mm

They are further classified as PLAIN & SERRATED depending on the type of bearing bar used. Gratings could be supplied in various shapes and sizes

  • Plain Grating
  • Serrated Grating

Applications Areas

Walk Ways | Step Treads | Trench & Drain Covers | Circular Platforms | Fencing (Grid Type) Boundary:

  • Cell Com has developed a robust and modular fencing solution using electro forged grating. Constituent members (flats/ twisted bars) cannot be cut by ordinary cutters unless torch cutting is done. This improves safety.
  • Widely used as a replacement for chain link type modular fencing applications

Supporting Accessories

Cell Com offers special Grating clamps & fixtures which do not require site welding and drilling and thus ideal where drilling & welding on site is not permitted.

  • Grating Fixture
  • Grating Clamp

Advantages

  • High load-bearing capacity (almost 20% more than manual gratings).
  • Easy to install and maintain/repair
  • High rate of production (fast deliveries).
  • Suitable for ventilation and natural lighting.
  • Durable in the harshest environment
  • Minimum distortion and accuracy of dimensions.
  • Corrosion resistant

Manufacturing Process

  • Twisted Bars are aligned on Bearing Bars for the desired mesh size on the Electro-forging machine.
  • Heat is generated at the metal intersection by passing a high Electrical current through the copper electrodes.
  • As the forging temperature is reached, high tonnage pressure is applied hydraulically on twisted bars, so as to forge weld every intersection of cross bars and bearing bars.
  • The Welded Cross bar is dragged automatically to bring the next cross bar under the welding electrodes. The grating panels are made in standard size of 1 mx6 m and the same process as above is repeated again and again till full length of panel (1m x 6m) is achieved.
  • The panels are then cut to the required grating sizes on circular power saw cutting machine & edge bearing bars (caging flats) are manually welded.
  • In house galvanizing or painting as required of the gratings is done before dispatch to customers.

Testing

Cell Com has an ultra-modern lab for testing all incoming, outgoing & in process material. The lab has complete Equipments to carry out physical & chemical properties of steel through UTM machine, Rockwell Hardness Tester, Carbon Apparatus, Hygrometer, etc., as per relevant IS codes. Testing Rig is used for load deflection test & UTM machine is used to carry out pull out test to check the strength of electro forged gratings.

Packing

Gratings are numbered according to drawing part number and are packed in bundles on steel/wooden pallets by means of steel strips.
