1. Composition of steel bar grating
   • Bearing bar: Flat steel characterized by width × thickness. Common sizes: 25×5mm, 30×5mm, 40×5mm, 45×5mm, 50×5mm
   • Cross bar: Typically twisted square steel, round steel or flat steel that holds the bearing flat steel
2. Bearing bar spacing and cross bar spacing
   • Bearing bar spacing: Typically 30mm (distance between centers of adjacent bearing bars)
   • Cross bar spacing: Typically 50mm or 100mm (distance between centers of adjacent cross bars)
3. Cross-sectional shape of the bearing flat bar: Rectangular, I-shaped or tooth-shaped flat steel
4. Steel grating construction form: Press-welded steel grating and pressure-locked steel grating
5. Shape and size of the steel grating: Customized according to project requirements
6. Material: Q235, 304 or 316 grade stainless steel
7. Surface treatment: Overall hot-dip galvanizing process for corrosion protection
