Pre galvanized Round Steel Pipe

Based on the mature pre-galvanizing pipe manufacturing process, Shixinda manufacturers' Pre galvanized Round Steel Pipe have significant comprehensive practical advantages. The surface of the pipes is bright and clean, with small dimensional tolerances and good straightness. They are stable in rust prevention under indoor dry conditions, cost-effective, suitable for large-scale lightweight construction projects, effectively reducing the initial procurement cost and shortening the construction preparation cycle. The product specifications cover all common sizes on the market. The pipe walls have uniform color without spots, no missed galvanizing, no zinc nodules or burrs. The finished products have a neat and beautiful appearance, facilitating direct assembly, secondary processing such as spraying, and are suitable for various civilian lightweight construction scenarios such as greenhouses, guardrails, decorative display stands, and electrical wiring.

Core Functional Positioning

Pre galvanized Round Steel Pipe are circular welded pipes manufactured using black steel pipe as the base material, through online hot-dip galvanizing or galvanized tape wrapping processes. These products are designed for lightweight anti-corrosion fluid transportation and lightweight steel structural support, making them suitable for civil engineering applications and small-to-medium industrial projects requiring general anti-corrosion piping solutions; unlike hot-dip galvanized seamless pipes, these products emphasize low cost, thin wall thickness, and ample stock availability, making them ideal for small-to-medium loads and indoor or mildly outdoor corrosive environments; however, they are not suitable for high-pressure fluid applications or heavy-duty pressure-bearing conditions.

Fluid transportation: low-pressure municipal water supply, fire sprinkler systems, agricultural irrigation, low-pressure gas branch lines, and industrial plant ventilation ducts.

Structural supports: photovoltaic mounting systems, greenhouse frames, guardrails and fences, billboard poles, temporary scaffolding for construction sites, furniture piping components, and carport or awning frames.

Protective accessories: wiring sleeves, lightweight protective pipes for mechanical equipment.

Core Selling Points

1. Advantages in corrosion resistance

The surface galvanizing layer is uniform and dense, effectively blocking moisture vapor while resisting slight acid and alkali exposure; its rust prevention performance is significantly superior to that of black-walled steel pipes and spray-painted steel pipes.

The galvanized strip process offers fast manufacturing speed, excellent coating adhesion, and resistance to peeling or detachment; when used indoors, it remains free from noticeable rust for 5–10 years.

2. Cost and Supply Advantages

Compared with hot-dip galvanized seamless pipes and thick-walled hot-dip galvanized round pipes: the price is 30% or more lower, offering exceptional cost-performance ratio;

Capable of mass production on continuous production lines, offering a comprehensive range of specifications with ample in-stock availability, short delivery lead times, and support for custom length cutting.

3. Easy to install and operate

The Pre galvanized Round Steel Pipe wall is uniform with standard roundness; bending, drilling, threading, and welding processes are relatively straightforward.

Equipped with a built-in galvanized protective layer, eliminating the need for secondary anti-corrosion painting; field installation eliminates the need for rust removal and spray-painting processes, thereby shortening the construction period.

4. Wide compatibility with various scenarios and lightweight design

The thin-walled specifications result in a lightweight design, making manual handling during the installation of greenhouses, railings, and photovoltaic mounting systems significantly easier;

Compatible with both cold and hot processing; can be bent into curved shapes for arched greenhouses or curved guardrails, meeting a wide range of design requirements.

5. Eco-friendly and aesthetically pleasing

Silver-gray matte metal finish requires no additional decoration, ensuring a unified and clean appearance for outdoor installations;

The galvanized coating is non-toxic and can be used in public welfare applications such as drinking water systems and greenhouse cultivation for fruits and vegetables.

Basic Specifications

Where can ShixinDa's galvanized steel round tubes be used?

Agricultural greenhouse sector (highest usage rate)

1.Greenhouse frames, spring and autumn cold greenhouses, vegetable arch greenhouses, strawberry greenhouses, and simple livestock housing structures.

2.Greenhouse arch supports, longitudinal beams, door frames, and film pressure support frameworks: Advantages include lightweight design, ease of bending, ample stock availability, and low manufacturing cost; these are the preferred choice for inland dry regions; for rainy coastal areas, hot-dip galvanized pipes are recommended.

Guardrails, fencing, and municipal lightweight protective barriers

1.Residential community perimeter fencing, courtyard railings, and balcony round tubular railings.

2.Simple roadside barriers, indoor protective railings for factory premises, and stair handrails.

3.Park landscape fencing, trellises, and climbing supports.

For wire threading protective sleeves (KBG and JDG metal wire threading pipes), the mainstream substrate material is galvanized round tubing:

1.Protection conduit for indoor electrical wiring (both high-voltage and low-voltage systems).

2.Fire-resistant and rust-resistant electrical conduit sleeves for concealed wiring in shopping malls, office buildings, and home renovation projects; intended exclusively for pre-installation within indoor dry walls.

Decorative, advertising, and display stand industries

1.Advertising lightbox brackets, outdoor lightweight billboard frames.

2.Exhibition trusses, exhibition stand supports, and temporary event scaffolding.

3.Furniture & Pipe Materials: wrought iron tables and chairs, storage shelves, coat hangers, bed frames.

Lightweight Steel Structures and Supports

1.Small-scale photovoltaic simple mounting brackets and residential distributed photovoltaic small mounting brackets.

2.Home-use parking sheds, simple warehouses, and sunshade structures – lightweight frames.

3.Equipment racks and internal support frames for mechanical equipment.

Aquaculture and Horticultural Supplies

1. Support structures for poultry farming sheds; poultry cage frames; 

2. Garden grape trellises, rose climbing trellises, and horticultural support columns.

FAQ

Q1: Which is better, Pre galvanized Round Steel Pipe or square steel pipes?

A: Circular steel pipes offer superior torsional resistance and low wind resistance, making them suitable for column/pile foundations and pipelines; square steel pipes are easier to connect and are more suitable for frame structures. Choose based on your specific requirements.

Q2: How is the required quantity calculated?

A: Based on load, span, and wall thickness specifications for design purposes, we provide free calculation tables and selection services.

Q3: Does our company support custom large-diameter or thick-walled components?

A: Yes, we fully support such requests; the maximum outer diameter can reach 2000 mm+, and we welcome you to provide your drawings.

Q4: What certificates are required for exports?

A: We provide a complete set of documents, including material certificates, galvanizing reports, Certificate of Origin, and SGS testing reports.
