FAQ
What is pre galvanized square steel pipe?
Pre galvanized square steel pipe is a type of mild steel square tube that has been coated with zinc before fabrication. This process adds a protective layer, making the pipe resistant to rust and corrosion right from production. It’s ideal for outdoor structures and harsh environments.
How is it different from hot dip galvanized pipe?
The main difference is the galvanizing process. Pre galvanized steel pipe gets a zinc coating at the manufacturing stage through a continuous hot-dip process before shaping into square tubes. Hot dip galvanized pipes are coated after forming, usually in a separate dipping process. Pre galvanized offers a more uniform coating and smoother surface, which is great for certain applications.
Can I order custom sizes?
Yes, you can. We offer custom sizes and lengths for practical needs. Whether you need specific dimensions for your project or custom wall thicknesses, we can usually accommodate your requirements.
What is the minimum order quantity?
The minimum order quantity depends on your specific needs and the product type. For small projects or samples, we can often supply in smaller quantities, but for bulk orders, we typically have a minimum that ensures cost efficiency.
Is it suitable for outdoor use?
Absolutely. The zinc coating on pre galvanized square steel pipe provides excellent corrosion resistance, making it perfect for outdoor applications such as fencing, structural framing, or any project exposed to the elements. It’s built to withstand weather and low maintenance over time.
