Q235B Medium-diameter Galvanized Square Pipe (DN80-DN100, 3.2mm Wall Thickness)

Product Overview

Q235B Medium-diameter Galvanized Square Pipe is a structural steel product designed for applications requiring corrosion resistance. It features a hot-dip galvanization coating on Q235B carbon steel, suitable for medium-diameter installations.

Specifications

Material

Constructed from Q235B carbon steel, which provides a yield strength of 235 MPa and tensile strength of 370-500 MPa. The steel meets GB/T 13793 standards for cold-formed welded structural sections.

Dimensions

• Nominal diameter (DN): 80 mm to 100 mm
• Wall thickness: 3.2 mm
• Length: Standard lengths of 6 m or 12 m, customizable upon request

Galvanization

Hot-dip galvanized with a zinc coating thickness of minimum 50 microns, complying with ASTM A123 or equivalent standards. This protects against rust in outdoor and humid environments.

Weight and Tolerances

Approximate weight: 15-25 kg/m depending on exact DN. Dimensional tolerances follow GB/T 6728, with outer dimension variance of ±0.5% and wall thickness variance of ±10%.

Applications

Used in construction frameworks, scaffolding, fencing structures, and water drainage systems. Suitable for industrial piping, agricultural installations, and electrical conduit supports where moderate strength and corrosion resistance are needed.

Features

• Resistance to atmospheric corrosion due to zinc coating
• Weldable and formable Q235B base material
• Uniform square cross-section for structural stability
• Compliance with international quality certifications

Asia Metal supports customization of steel products in different sizes and specifications to meet specific project requirements.
