قیمت 30*30 Steel Square Box

Using high-quality raw materials and choosing the appropriate type for a specific use case is critical in all industries. However, its importance is significantly magnified in sectors where human safety is at stake. One such example is the construction and civil engineering industry, where the use of reliable materials is essential.

The safety of individuals within a structure is directly tied to the quality of the materials used. Square (SHS) and rectangular hollow sections (RHS), such as box profiles, are frequently used across various structural applications.

One of the widely used profiles in the industry is the 30*30 steel square box section. As a type of hollow structural section (HSS), it comes in many variations. In this article, we will introduce the 30*30 steel square boxes, their types, and their applications in various industries.

What Is a 30*30 Steel Square Box?

The 3×3 centimeter (or 30×30 millimeter) box section is a commonly used square hollow section. As the name suggests, it has a square cross-section.

These sections are typically manufactured in thicknesses ranging from 0.7 mm to 3 mm and conform to DIN 2395 and JIS G3466 standards. Known for their high strength, these profiles are preferred in situations where enhanced structural integrity is required.

Range of 30*30 Steel Square Box Variations

Steel square box sections are manufactured in several types. The two primary criteria for categorizing a 30*30 steel square box are the material type of the steel sheet and the section thickness. Below, we elaborate on each:

Based on Material Type:

30*30 steel square boxes are produced in the following material categories:

• Mild steel (iron)

• Galvanized steel

• Stainless steel

• Aluminum

• Composite materials

Based on Thickness:

Different thicknesses result in distinct characteristics and applications:

Lightweight Tube
If the steel sheet used has a thickness of 2 mm or less, the resulting box section is considered lightweight, commonly referred to as a furniture tube in layman’s terms. Benefits include:

• High surface quality and finish

• Precision in manufacturing

• Good formability

Heavy-Duty Tube
In contrast, when the thickness exceeds 2 mm, the profile is classified as heavy-duty. Its features include:

• High weldability

• Enhanced surface hardness

• Excellent torsional and flexural stability

• Increased structural strength

Applications of 30*30 Steel Square Box

As noted, 30*30 steel square boxes are produced in both lightweight and heavy-duty categories, each suitable for different applications. Their presence in steel structures significantly increases the moment of inertia in both axes, which improves the overall rigidity and strength of the structure. Main applications include:

• Steel shed construction (warehouses and workshops)

• Bridge construction

• Industrial building frameworks

• Manufacturing of household appliances

• Door and window fabrication

• Structural framing for buildings

How to Calculate the Weight of a 30*30 Steel Square Box

One of the most critical pricing factors for 30*30 steel square boxes is their weight, which is directly influenced by the section’s length and thickness. As these parameters increase, so does the weight. Generally, the weight of a 30*30 steel square box can be calculated using the following formula:

weight of a 30*30 steel square box (kg/m) = (Steel Density * Width * Height * Thickness) / 1000

Advantages of Using 30*30 Steel Square Box

Thanks to their numerous advantages, 30*30 steel square boxes are widely used in various industries. Key benefits include:

• Enhanced structural resistance compared to materials like wood

• Reduction in dead load due to the tube’s relatively low weight

• Cost-effective and budget-friendly

• High-quality surface finish and dimensional precision

Is the Price of a 30*30 Steel Square Box Stable?

Naturally, no. The price of 30*30 steel square boxes, and steel products in general, is constantly subject to market fluctuations. Influential factors include:

• Supply and demand dynamics

• Exchange rate variations

• Tube thickness

• Base steel sheet prices

• Cost of raw materials
