Products Description
ASTM A252 ERW Piling Steel Pipe is a professional electric resistance welded steel pipe, specially designed for foundation construction casing and piling engineering. Complying with ASTM A252 international standard, this steel pipe serves as permanent load-bearing piling components or outer casing for cast-in-place concrete piles. Manufactured by advanced ERW welding technology, it features uniform wall thickness, smooth inner and outer surface, excellent structural integrity and stable mechanical properties. It is widely applicable for various deep foundation projects, effectively bearing vertical building loads and lateral soil pressure, ensuring the stability and safety of infrastructure engineering. We provide full-size customized services and strict quality inspection to meet global construction project standards.
