Frequently Asked Questions (FAQ)

What are the primary applications of these pre-galvanized steel pipes?

These pipes are specifically designed for structural support in greenhouse construction, offering an optimal balance of strength, durability, and corrosion resistance for agricultural environments.

What is the difference in zinc coating between hot-dip and pre-galvanized pipes?

Hot-dip galvanized steel pipes offer a heavier zinc coating of 220–350G/M2, which provides superior long-term corrosion resistance. Pre-galvanized (Gi) pipes feature a zinc coating of 60–80G/m2, which is more cost-effective and suitable for standard indoor and outdoor structures.

Can the wall thickness and length of the pipes be customized?

Yes. We support custom wall thicknesses ranging from 0.6mm to 20mm, and custom lengths from 1 to 14 meters to fit the specific requirements of your greenhouse project.

What international standards do your steel pipes comply with?

Our steel pipes are manufactured in compliance with major global industrial standards, including ASTM, DIN, JIS, and BS, ensuring reliable quality and structural safety.

How are the steel pipes packaged for shipment?

The pipes are securely packed either in bundles or customized according to the buyer's shipping requirements to prevent damage during international transport.
