13 May ASTM A847 Pipe & Tube Sizes & Availability at Central Steel Service
When project timelines are tight and performance matters, material availability becomes just as important as material quality. At Central Steel Service, customers can count on both, especially when it comes to ASTM A847 hollow structural sections (HSS).
With a deep inventory of square and rectangular weathering steel tubing and pipe, we’re proud to help engineers, fabricators, and contractors stay on schedule without sacrificing strength or durability.
What Is ASTM A847?
ASTM A847 is a high strength, low alloy weathering steel grade that governs Hollow Structural Sections and Pipe. Designed for exposed applications, it forms a protective oxide layer that reduces corrosion and often eliminates the need for painting.
With a minimum yield strength of 50 ksi, ASTM A847 tubing is built for structural performance in demanding environments.
Common applications include:
- Pedestrian bridges
- Highway Bridges
- Outdoor pavilions
- Architectural exposed structural applications
- Fencing
- Guardrail
- Guide Rail
- Sign Posts
The Benefits of Using ASTM A847
Because weathering steel HSS are both high-strength and lightweight, engineers can achieve the same load-bearing performance with smaller or thinner sections — reducing material usage, fabrication costs, and overall project weight.
- Structural Efficiency: The inherent strength of weathering steel HSS means you can design leaner structures without sacrificing performance. Their efficient strength-to-weight ratio allows bridges to maintain rigidity and stability with fewer tons of material, which also simplifies installation.
- Lower Project and Life-Cycle Costs: Less steel translates to lower upfront costs in material, shipping, and fabrication — and the corrosion-resistant nature of weathering steel further reduces maintenance and repainting expenses throughout the bridge’s service life. The result: a more economical project from start to finish!
- Reduced Environmental Impact: Using less material supports sustainability goals by lowering embodied carbon and conserving natural resources. Weathering steel also eliminates the need for paint systems, reducing environmental waste and maintenance emissions over time.
- Enduring Performance and Aesthetic Appeal: Weathering steel HSS develop a warm, natural patina that blends beautifully with the environment while protecting the steel beneath. This combination of strength, longevity, and visual appeal makes them a top choice for all sorts of applications.
