Welded Grating vs Swage-Locked Grating
Welding uses heat to fuse the bars; swaging cold-forms them into a mechanical lock. The difference matters most for aluminium and for distortion-sensitive panels.
Use welded grating for the strongest, most economical carbon-steel flooring. Use swage-locked grating for aluminium and where heat distortion must be avoided — offshore, food and prefabricated panels.
FAQ
Why is aluminium grating swage-locked instead of welded?
Welding aluminium is difficult and distorts thin bars, so cross bars are cold-swaged into the bearing bars for a clean, strong mechanical lock without heat.
Is swage-locked grating as strong as welded?
For the same material it is close, but welded carbon-steel grating remains the strongest and most economical for heavy structural loads.
