Our grating welders (steel grating machines) are specialized machines for the manufacture of forge welded gratings and grating welders with fast and firm welding and power saving advantages.

We use advanced intermediate frequency (1000Hz) technology to manufacture our machines. With strong instantaneous electric current and short welding time, our machines can save approx. 30-50% power energy compared with low frequency (50Hz) grating welders. Moreover, in contrast to low frequency (50Hz) grating welders, our matched transformers can even save 40-50% KVA, so our grating welder is the first choice for your investment.
