Minimal Wall Rectangular Tube

In the realm of structural and architectural design, achieving maximum strength with minimal material weight is a constant engineering pursuit. This is where the significance of thin-walled rectangular profiles becomes paramount. For applications demanding a sleek aesthetic, efficient load-bearing, and material economy, our **Minimal Wall Rectangular Tube** offers an optimal solution. This product category is engineered for scenarios where heavy sections are unnecessary or undesirable, providing a perfect balance between structural integrity and lightweight design. Closely related solutions include the Light Gauge Rectangular Hollow Tube, ideal for framing and supports where weight is critical. Similarly, the Slim Thickness Rectangular Steel Pipe serves applications requiring clean lines and reduced mass. For broader structural sections with a focus on efficient material use, the Low Wall Rectangular Hollow Section is a key offering. Finally, precision-focused projects benefit from the Fine Wall Rectangular Steel Tube, known for its consistent dimensions and excellent surface finish. Our minimal wall tubes are manufactured to exacting standards, ensuring high performance in furniture frameworks, automotive roll cages (for non-critical structural members), exhibition stands, and lightweight industrial frames.

The defining characteristic of the **Minimal Wall Rectangular Tube** lies in its precise geometric and material specifications, which directly influence its mechanical properties and suitability for various loads. The product is typically fabricated from high-strength, low-alloy (HSLA) steel or carbon steel, offering an excellent strength-to-weight ratio. Key parameters that engineers and fabricators evaluate include external dimensions, wall thickness, and sectional properties. Below is a detailed breakdown of standard specifications and performance metrics for our product range. These specifications ensure that the **Minimal Wall Rectangular Tube** meets the rigorous demands of modern design, providing reliable performance while optimizing material usage and cost-efficiency.

Material Properties & Performance Data

The following list details the core material characteristics and calculated sectional properties for a standard grade, which are crucial for structural analysis:

• Standard Grade: S355J2H / ASTM A500 Grade C
• Yield Strength (Min): 355 MPa / 345 MPa
• Tensile Strength: 470 - 630 MPa / 415 MPa Min
• Elongation: ≥ 22% (on a standard gauge length)
• Sectional Area: Calculated based on exact dimensions; e.g., a 50x25x1.8mm tube has an approximate area of 2.54 cm².
• Moment of Inertia (Ixx, Iyy): Values are provided in technical datasheets for precise bending stiffness calculations.
• Section Modulus (Zxx, Zyy): Critical for determining the bending moment capacity of the section.
• Surface Finish: Mill finish (hot-rolled pickled and oiled) or galvanized (to EN ISO 1461) for corrosion protection.
• Primary Applications: Light structural frameworks, machinery guards, DIY projects, furniture chassis, display systems, and automotive accessories.
