FAQ for Steel Supply Services
What is Galvanized Steel Pipe?
Galvanized Steel Pipe is steel pipe coated with zinc to protect the surface from corrosion. It is commonly used for construction, water supply, scaffolding, fencing, greenhouse, and outdoor engineering applications.
What is the difference between hot-dip galvanized pipe and pre-galvanized pipe?
Hot-dip galvanized pipe is galvanized after pipe production, giving both inner and outer surfaces zinc protection. Pre-galvanized pipe is made from galvanized steel strip or coil before forming and welding, and is often used for lighter structural and general applications.
What standards can SKSteel supply for Galvanized Steel Pipe?
SKSteel can supply Galvanized Steel Pipe according to ASTM A53, ASTM A500, ASTM A795, BS1387, EN10255, EN10219, JIS G3444, GB/T and other project standards.
Can SKSteel customize zinc coating thickness?
Yes. Zinc coating thickness can be supplied according to customer requirements, project environment, and applicable standard. Common zinc coating ranges are available for both pre-galvanized and hot-dip galvanized pipes.
Can SKSteel provide customized processing for Galvanized Steel Pipe?
Yes. Cutting, threading, grooving, drilling, end caps, bundling, marking, packing, and custom length services are available.
