Main Types of ASTM A36 Carbon Steel Grating
When purchasing ASTM A36 steel grating, buyers should select the right type based on application conditions.
Welded ASTM A36 steel grating is the most popular type for industrial applications.
Features:
High structural strength
Strong connection between bearing bars and cross bars
Suitable for heavy loads
Easy installation and maintenance
Common applications:
Industrial platforms
Factory walkways
Steel structures
Equipment access areas
Serrated grating features a serrated surface on the bearing bars, providing improved anti-slip performance.
Advantages:
Better safety in wet or oily environments
Increased traction
Reduces slipping risks
Recommended for:
Oil and gas facilities
Chemical plants
Offshore platforms
Drainage areas
Smooth surface grating provides a flat walking surface and is commonly used where comfort and easy cleaning are required.
Applications:
Commercial buildings
Maintenance platforms
Indoor industrial areas
Heavy-duty steel grating uses thicker bearing bars and stronger structures to handle high loads.
Typical uses:
Vehicle access areas
Mining facilities
Heavy machinery platforms
Industrial bridges
Applications of Carbon Steel Grating
ASTM A36 steel grating is widely used across multiple industries.
ASTM A36 Steel Grating vs Other Carbon Steel Grades
