What is 34mm steel pipe?

A 34mm steel pipe (also known as D34 steel pipe) is a type of steel pipe with an outer diameter of 34mm, manufactured from high-quality steel coils using electric-resistance welding (ERW) or high-frequency welding technology. With good mechanical strength, stable load-bearing capacity, and high flexibility during installation, 34mm steel pipes are widely used in civil construction, industrial projects, mechanical fabrication, and technical systems.

This is a medium-sized steel pipe, suitable for applications requiring durability without excessive weight, offering optimal performance and a reasonable price.

Common Types of 34mm Steel Pipes

Black steel pipe (Φ34)

• Characteristic black surface, non-galvanized.

• Low cost, easy to process.

• Suitable for frames, mechanical structures, railings, scaffolding, etc.

Galvanized steel pipe (Φ34)

• Coated with hot-dip or electro-galvanized zinc for rust protection.

• Highly durable in outdoor or humid environments.

• Often used in water/gas piping systems and pre-engineered steel buildings.

ERW welded steel pipe (Φ34)

• Welded from steel coils using high-frequency ERW technology.

• High uniformity, smooth surface, excellent tightness.

• Common in mechanical and steel structure applications.

Seamless steel pipe (Φ34)

• No welding line, produced using seamless casting technology.

• Withstands high pressure, suitable for heavy-load or high-pressure environments.

Characteristics of 34mm Steel Pipes

• Good load-bearing capacity: Thick walls and strong structure withstand impact and heavy loads.

• High durability: Resistant to deformation, temperature changes, and environmental effects.

• Easy to fabricate: Can be cut, bent, welded, and drilled without affecting quality.

• Reasonable price: Falls into the medium-size category, more cost-effective than larger steel pipes.

• Various types: Available in black, galvanized, welded, and seamless options.

Applications of 34mm Steel Pipes

Construction

• Used for building frames, roofing structures, scaffolding, railings, and support columns.

• Auxiliary structures in factories and pre-engineered buildings.

Mechanical engineering

• Fabrication of machine frames, workbenches, racks, and storage shelves.

• Used in manufacturing of household and industrial equipment.

Technical systems

• Water and gas pipelines, fire-fighting systems.

• Ventilation and HVAC installations.

Agriculture & farming

• Barns, greenhouses, irrigation frames, poles, and mesh structures.

Other uses

• Protecting electrical cables and telecom infrastructure.

• Furniture fabrication (tables, chairs, decorative shelves, etc.).
