Electroforged Grating

In this process, square twisted cross bars are welded or electroforged to the rectangular shaped bearing bars by a process that combines heavy hydraulic pressure with a heavy electric current. Pre-straightened bearing bars are cut and fed in while the cross bars are fed directly from coils. Two crossbars are shot into the welder and placed under the electrodes by pulling hooks for simultaneous welding.

SMOOTH SURFACE GRATING
SERRATED SURFACE GRATING​

ELECTRO FORGED GRATING
  •   HOMOGENEOUS COMBINATION OF BEARING BAR AND CROSS BAR
  •   MASS PRODUCTION
  •   LESS TIME CONSUMPTION PROCESS
  •   ECONOMICALLY LESS COST
  •   QUALITY FINISHED PRODUCT
  •   DIMENSIONAL ACCURACY IS MORE
  •   ANTI SLIP PROPERTY BY USING SQUARE TWISTED BAR
  •   DISPATCH IS FASTER DUE TO READY STOCK OF STANDARD SIZE GRATINGS
  •   NO AIR GAP BETWEEN WELDED JOINTS
  •   WASTE IS LESS COMPARED TO MANUAL GRATINGS
MANUAL WELD GRATING
  •   HETEROGENEOUS COMBINATION OF BEARING BAR AND CROSS BAR
  •   BATCH PRODUCTION
  •   MORE TIME CONSUMPTION PROCESS
  •   COMPARATIVELY HIGH COSTING PROCESS
  •   SEMI FINISHED QUALITY
  •   IMPROPER DIMENSION AT DIFFERENT SECTION
  •   SLIPING TENDENCY SHOULD BE MORE BECAUSE SURFACE IS COMPLETELY FLAT(SMOOTH)
  •   THESE CAN NOT STOCKED
  •   AIR GAP BETWEEN WELDED JOINTS CAUSES CORROSION
  •   WASTE OF RAW MATERIAL IS MORE
