ASTM A847 Weathering Steel Pipe
ASTM A847 steel pipe is a weathering steel, a high-strength, low-alloy steel covering cold-formed welded square and rectangular pipes.
1. Standard: ASTM A847
2. Shape: round, square, rectangular
Square size: 25mm x 25mm to 150mm x 150mm, meeting a variety of engineering needs.
Rectangular size: 50mm x 25mm to 200mm x 100mm, suitable for a variety of building and structural engineering.
Circular size: The diameter range is usually between 21.3mm and 323.9mm, widely used in bridges, buildings and other fields requiring high strength and corrosion resistance.
3. Wall thickness: between 1.5mm and 12.5mm
4. Length: 6 meters or 12 meters, can also be customized according to customer needs.
5. Type: Cold-formed welded steel pipe, with excellent tensile strength and weather resistance, especially suitable for structural applications exposed to outdoor environments.
