FAQ: Technical Terms & Expert Answers

1. What types of steel can be used in metal grating for sale?

Answer: Carbon steel (A36/Q235/Q195), stainless steel (304/316L), and aluminum alloys. Carbon steel is most popular for its cost-effective strength, while stainless steel provides maximum corrosion resistance.

2. What is the difference between swage-locked and welded steel grating?

Answer: Swage-locked grating uses hydraulic pressure to force crossbars through notches in the bearing bars, locking them in position for superior rigidity. Welded types fuse cross and bearing bars by electric resistance, allowing for rapid mass-production but less customization.

3. Which standards govern the production and installation of steel grating?

Answer: Major standards include ISO9001 (quality management), ANSI/NAAMM MBG531 (design/installation), OSHA 1910 (safety), and EN 1090 (EU market).

4. How is slip-resistance achieved and measured?

Answer: By serrating the bearing bars and/or cross bars. Measurement uses the R-Value or PTV (Pendulum Test Value), complying with EN 13501 for slip resistance.

5. What is the typical service life of hot-dip galvanized carbon steel grating?

Answer: In industrial and outdoor environments, service life is generally 20–30 years per Galvanizers Association, depending on climate and exposure.

6. What are standard grating panel sizes and thicknesses?

Answer: Most common panels are 1000x6000mm, 1000x4000mm; bearing bar thicknesses 3–8mm, heights 22–65mm, mesh opening 30x100mm or customized.

7. How do I select the right types of steel grating for my application?

Answer: Consider load requirements, span, corrosion environment, slip requirements, and regulatory standards. Consult with supplier's engineering team for specification review.
