Why Steel Grating Thickness Determines Project Success

Industrial engineers specify steel grating thickness
ranging from 1/4" to 1-1/2" based on ANSI/NAAMM MBG 532 standards. Our stress tests reveal:

  • 19mm thickness handles 5,000 lbs/ft² static load
  • 38mm variants withstand 12,500 lbs/ft² impact loads

Thermal expansion rates remain stable at 0.0000065/inch/°F across thickness variations, ensuring structural integrity from -40°F to 120°F.

FAQS on steel grating thickness

Q: What is the standard steel grating thickness range for industrial applications?

A: Standard steel grating thickness typically ranges from 3/16" to 1/2", depending on load requirements. Thicker gratings (e.g., 1/2") are used for heavy-duty industrial settings, while thinner options suit pedestrian areas. Always consult specifications from suppliers like Borden Steel Grating or Greatweld Steel Grating for precise measurements.

Q: How does steel grating thickness impact load-bearing capacity?

A: Thicker steel grating (e.g., 3/8" or 1/2") supports higher loads, such as vehicular traffic or heavy machinery. Thinner gratings (e.g., 1/4") are ideal for walkways or platforms with lighter use. Manufacturers like Greatweld Steel Grating provide load charts based on thickness and spacing.

Q: Are Borden Steel Grating and Greatweld Steel Grating thickness standards different?

A: Both brands adhere to industry standards (e.g., ANSI/MBMA), but thickness options may vary slightly. Borden Steel Grating often offers 3/16"-3/4" thicknesses, while Greatweld Steel Grating focuses on 1/4"-1/2" for commercial use. Check technical datasheets for exact specifications.

Q: Can steel grating thickness affect corrosion resistance?

A: Thickness doesn’t directly impact corrosion resistance, but thicker gratings may last longer in harsh environments due to material durability. Brands like Greatweld Steel Grating often combine thickness with coatings (e.g., galvanizing) for enhanced protection.

Q: Is custom steel grating thickness available from major suppliers?

A: Yes, suppliers like Borden Steel Grating and Greatweld Steel Grating offer custom thicknesses for specialized projects. Custom orders may require longer lead times and additional cost calculations. Always confirm tolerances and testing certifications during ordering.
