What's the difference between welded and press-locked steel grating?
Welded grating fuses bearing bars and cross bars at every intersection for maximum strength, while press-locked grating mechanically clamps the bars without heat — giving a smoother, more decorative surface at a lower cost.
Which material should I choose for marine or chemical environments?
304/316 stainless steel grating resists salt spray and most chemical exposure; hot-dip galvanized carbon steel is the cost-effective choice for general outdoor and industrial use.
