EN10327 DX51D+Z Galvanized Square Pipe – Durable Zinc-Coated Steel Tubing for Structural & Construction Use

| PRODUCT INTRODUCTION

DX51D+Z galvanized square pipe is manufactured from cold-formed steel strip conforming to the EN 10327 standard, with a zinc coating applied via hot-dip galvanization. The DX51D grade ensures good forming properties, while the zinc layer (+Z) provides long-term protection against rust and atmospheric corrosion.

This product is widely used in both indoor and outdoor environments due to its durability and aesthetic surface finish. It is available in various wall thicknesses and lengths, with customizable coating weights according to client requirements.

APPLICATION

DX51D+Z galvanized square steel pipes are widely used in civil construction, light steel structures, and fabrication sectors due to their excellent corrosion resistance, processability, and clean appearance. Typical uses include:

• Structural framing – greenhouses, warehouses, scaffold frames
• Fencing and gates – boundary fencing, security structures
• Furniture frames – modular shelving, metal furniture
• Automotive body parts – support beams, crossbars
• HVAC and mechanical supports
• Electrical cable tray systems

In coastal or humid areas, the zinc coating ensures extended product life and minimal maintenance.

• Yield Strength (Re): ≥ 140–300 MPa
• Tensile Strength (Rm): 270–500 MPa
• Elongation (A80): ≥ 22%
• Formability: Excellent for bending, rolling, and stamping
• Weldability: Suitable for resistance welding and arc welding
