Detailed engineering information for procurement managers, structural designers, and logistics coordinators.
Q235 steel yields at a nominal 235 MPa, making it suitable for standard scaffolding and framing. Q355B steel yields at a higher 355 MPa, allowing designers to reduce wall thickness and weight while maintaining necessary structural capacity under high loads.
The steel is dipped in molten zinc, creating a metallurgical bond with several zinc-iron alloy layers and an outer pure zinc layer. This provides barrier protection and acts as a sacrificial anode, preventing rust even if the pipe's surface is scratched.
Under standard structural use, a zinc coating of 45-85 microns can last 15 to 20 years. In highly corrosive coastal or wet locations, the expected service lifespan is typically between 10 and 15 years before maintenance is needed.
We use automated cutting, punching, and sizing systems to control outer diameter, wall thickness, and length deviations within a tight tolerance of ±1mm, helping to ensure smooth assembly on the job site.
