The A847 steel specification further adds atmospheric corrosion resistance to the A500 standard.

Peak Kong Special Steel rises to the challenge and launches our range of weather-resistant grade products. Similar to our A500 product, it is a cold formed high strength/low alloy steel. But over time, the product forms a permanent, stable light brown rust layer that protects the steel from corrosion, eliminating the need for painting and repainting.

• Our weather-grade steel pipes are produced to ASTM A847 standards, which are similar to ASTM A500 (with the addition of steel that resists atmospheric corrosion)
• Minimum yield strength is 50 ksi, minimum tensile strength is 70 ksi, and minimum elongation is 19%.
• Common applications: bridges, sidewalks, utility/light poles.

• 3/16 inches
• 1/4 inch
• 3/8 inch

Typically, initial cost savings are around 10-15%. This product avoids the cost of painting... saving at least 30% over the life of the structure.

Weathered finishes provide a natural look to outdoor environments without the need for VOC paint or sandblasting—both of which can be harmful to the environment.
