Sector Shaped Steel Tube

Shixinda's supplier manufactures this Sector Shaped Steel Tube, using two mature processes of cold rolling extrusion and high-frequency welding for shaping. It is also equipped with multiple surface treatment options such as black annealing, hot-dip galvanizing, and stainless steel polishing.

It combines the advantages of decorative appearance, safety in use, and structural load-bearing, and is widely used in landscape guardrails, stair handrails, photovoltaic supports, commercial display stands, door and window profiles, and transportation vehicle frames, etc.

Product details

1. Section and Process Specifications

The core standard model adopts vertical double straight edges combined with an integrated circular arc surface, with smooth line transitions without sharp corners; apart from the conventional 90° right-angle fan shape, special engineering can customize small angles and semi-circular arc irregular sections. The forming process is divided into two types: high-frequency welding fan-shaped tubes have high production efficiency and outstanding cost performance, suitable for large-scale guardrails and greenhouses projects; cold extrusion integrated forming fan-shaped tubes have higher dimensional accuracy and stronger overall structure, mostly used for load-bearing components of precision equipment.

2. Optional Materials and Surface Anti-corrosion Processes

The base material is selected from national standard Q235B, Q355B carbon structural steel, and 304, 316 stainless steel materials are available for selection; surface treatment includes blackened bare tube, high zinc layer hot-dip galvanizing, electrostatic spraying, and stainless steel mirror finish polishing, suitable for different working conditions such as indoor dry, outdoor rain, and mild acid-base corrosion. The wall thickness range is 0.7mm to 8mm, regular stock sections are 40×40 to 78×78, and other non-standard sizes support mold production.

3. Physical Properties and Processing Compatibility

The arc-shaped section of Sector Shaped Steel Tube optimizes the force distribution, under the same load conditions, compared with flat tubes and ordinary round tubes, it has stronger resistance to bending and twisting, and thin-walled thick materials can be selected to reduce the overall weight and procurement cost. The pipe material has excellent plasticity, and it can complete the entire process of laser cutting, fixed-length cutting, drilling, bending, and welding processing. The coating adhesion of the circular arc surface is stable, and the finished product spraying is less likely to peel off, significantly reducing the processing plant's rework losses.

4. Full-scenario Adaptation Range

Outdoor scenarios: photovoltaic support frames, courtyard protective fences, road landscape guardrails, greenhouse supporting brackets;

Home decoration and commercial: stair handrails, door and window decorative frames, supermarket product display stands;

Mechanical transportation: electric vehicle frames, small equipment support beams, lightweight mechanical frames.

Surface treatment process

I. Carbon steel basic model

1. Black anodizing: Low cost, convenient for self-painting and powder coating. The preferred choice for indoor furniture and guardrail processing.

2. Phosphating treatment: Provides a base layer, enhances coating adhesion, and offers short-term rust prevention.

II. Galvanized anti-corrosion model

1. Galvanized strip: Abundant in stock, low price, suitable for mild indoor / short-term outdoor use.

2. Hot-dip galvanizing: Thick zinc layer, strong anti-corrosion, specifically for photovoltaic, municipal, overseas projects, and coastal scenarios.

3. Cold galvanizing (electro-galvanizing): Poor anti-corrosion performance, not recommended for outdoor use.

FAQ

1. Q: What are the common specifications of the Sector Shaped Steel Tube available for purchase?
