ASTM Specification
Menu
The A847 steel specification takes the A500 standards a step further with the addition of atmospheric corrosion resistance.
Bull Moose rises to the challenge with our Weathering Grade product line. Like our A500 entries, it’s cold-formed high-strength/low-alloy steel. But over time, this product develops a permanent, stable, light-brown patina that protects it from corrosion and eliminates the need for painting and re-painting.
Available in square and rectangular forms, A847 steel is an ideal, cost-effective choice for walkways, bridges, railings, and other structures that are directly exposed to the elements.
Weathering Grade Product Details
- Our Weathering Grade steel tube is produced per ASTM A847, which mirrors ASTM A500 (plus atmospheric-corrosion-resistant steel).
- 50 KSI min. yield, 70 KSI min. tensile, 19% min. elongation
- General applications: bridges, pedestrian walkways, utility/light poles.
- Normally in stock:
- 3/16″
- 1/4″
- 3/8″
- If you require a custom size, please inquire about lead time.
- The typical initial cost savings equal about 10-15%. This product avoids the expense of painting… resulting in savings of at least 30% over the structure’s lifetime.
- The weathered finish provides a natural look for outdoor environments and doesn’t require either VOC paint or blasting—both of which can be harmful to the environment.
