316 Welded Square Pipe 304 Stainless Steel 316 Square Tube

Brand ZCXH
Product origin Shandong,China
Delivery time 10-20 days
Supply capacity 1000 tons/ month

Our 304 Stainless Steel and 316 Welded Square Pipes, along with 316 Square Tubes, offer exceptional features. 304 pipes, with 18% chromium and 8% nickel, resist corrosion well in general conditions, perfect for food, construction, and water systems. Their smooth surface ensures easy cleaning and low fluid resistance. 316 welded square pipes and square tubes, containing 2 - 3% molybdenum, have enhanced resistance to pitting and crevice corrosion. This makes them ideal for harsh environments like marine, chemical, and coastal applications. All are precisely welded, ensuring high strength and leak - free performance. Available in various sizes, they meet diverse industrial and construction needs.

1.Shared Advantages of Square Cross-Section (304/316 Common)

Regardless of material grade, the square shape of these pipes/tubes provides unique structural benefits that outperform round tubes in many scenarios:

- Even Load Distribution & High Rigidity

The uniform 4-sided structure ensures stress (from weight, pressure, or torsion) is spread evenly across all sides, avoiding localized stress concentration. Compared to round tubes of the same material grade and wall thickness:

Higher moment of inertia (a key metric for bending resistance): Square tubes are 20–30% more resistant to bending or twisting, making them ideal for load-bearing applications (e.g., building columns, machinery frames, railings).
Stable structural support: Flat sides prevent "rolling" during installation, ensuring stability for fixed components (e.g., shelf brackets, signposts).

- Easy Installation & Versatile Splicing

Flat surfaces simplify attachment to walls, floors, or other flat components (no need for special adapters—direct welding, bolting, or clamping works).
Precise right-angle joints: Square tubes can be easily cut and spliced into rectangular frames or multi-directional structures (common in furniture, exhibition stands, or industrial equipment).

- Aesthetic & Space-Saving Design

Clean, linear appearance: Square tubes have a modern, minimalist look, suitable for decorative applications (e.g., interior railings, store displays, furniture legs).
Space efficiency: Unlike round tubes, square tubes fit tightly in corners or compact spaces (e.g., narrow industrial machine enclosures, residential balcony balustrades).

2.Advantages of Welded Processing (for 304/316 Welded Square Pipes)

Most 304/316 square pipes on the market are welded (manufactured by rolling stainless steel strips into square shapes and welding the seam). This process offers critical benefits for industrial and structural use:

- Cost-Effectiveness

Welded pipes avoid the complex extrusion or forging processes of seamless pipes, reducing production costs by 15–25%. This makes 304 welded square pipes accessible for large-scale projects (e.g., construction railings, agricultural equipment), while 316 welded square pipes balance performance and budget for mid-range harsh-environment applications.

- Dimensional Flexibility

Welded processing supports a wide range of sizes to meet custom needs:

Standard side lengths: 10x10mm (small decorative tubes) to 200x200mm (large structural tubes).
Wall thickness: 0.8mm (lightweight use, e.g., display frames) to 15mm+ (heavy-duty industrial use, e.g., offshore platform supports).
Manufacturers can quickly produce non-standard sizes (e.g., 35x35mm, 80x80mm) for specific projects, unlike seamless pipes which have limited size options.

- Consistent Quality for Non-High-Pressure Scenarios

Modern welding technologies (e.g., TIG, laser welding) ensure the weld seam is strong, smooth, and free of defects. For non-high-pressure applications (most structural, decorative, or low-pressure fluid transport uses), welded square pipes meet strength requirements—their weld seam tensile strength is typically ≥80% of the base material, avoiding cracking under normal loads.
