What are the load-bearing capacities of cast iron outdoor bench crossbars?

Cast iron outdoor bench crossbars are renowned for their durability and strength, making them a popular choice for public parks, gardens, and commercial spaces. The load-bearing capacity of these crossbars typically ranges between 300 to 600 pounds (136 to 272 kg), depending on factors like thickness, design, and manufacturing quality.

Key factors influencing their strength include:

1. Material Thickness: Thicker crossbars (e.g., 1/2 inch or more) offer higher load capacity.

2. Design: Reinforced or ribbed designs enhance structural integrity.

3. Installation: Proper anchoring and spacing between crossbars distribute weight evenly.

Cast iron’s inherent resistance to weathering and corrosion ensures long-term performance, though regular maintenance (e.g., rust-proof coatings) is recommended. For heavy-duty use, opt for crossbars with welded joints or additional support brackets. Always check manufacturer specifications for precise weight limits to ensure safety and longevity.
