FAQS
Q: Can you give me a fatory 4x4 square tubing 20 ft price
A: Yes, we can. But the purchaser requires a minimum order quantity of around 5 tons.
Q: What is 4x4 square tubing price per foot?
A: The 4x4 Square Tubing Price Per Foot is a floating price. To know the specific price, please consult the account manager
Q: How to know 4x4 square steel tubing weight?
A: Generally, a rough weight can be obtained through weight calculation, and the actual weight can be determined through weighing.
Q:
How To Know 4x4 square tubing strength?
A: The strength of square tubes is determined through a series of calculations and consideration of multiple factors. The following are several key aspects for determining the strength of square tubes:
Calculation formula:
Koch's formula: S=(M * y)/W, where S is the strength of the square steel pipe section, M is the bending moment, y is the maximum distance between the section and the neutral axis, and W is the section modulus that resists bending moment.
Eisenberg formula: S=(My)/3 (I * 1/2), where S, M, y are the same as the Coriolis formula, and I is the moment of inertia of the cross-section.
Lorentz formula: S=M/W, where S, M, and W are the same as the Coriolis formula.
Strength formula (based on strength theory): σ=F/A, where σ is strength, F is force, and A is area.
Influencing factors:
Material: The material of square tube plays an important role in its strength. For example, using high-strength materials such as Q235, Q345, etc. can better withstand external forces.
Manufacturing process: Different manufacturing processes can result in differences in the strength of square tubes.
Section shape: The section shape of a square tube (including side length and wall thickness) also affects its strength.
Other considerations:
Actual stress state: In practical applications, square tubes may be subjected to various stresses, so the influence of actual stress state on strength needs to be considered.
Load distribution: The distribution of loads can also affect the strength of square tubes.
Material properties: The elastic modulus, yield strength, and other characteristics of the material are also important factors in determining the strength of square tubes.
Practical application:
In practical applications, the strength of the square tube is usually estimated and tested based on specific usage scenarios and requirements, combined with the above formulas and influencing factors.
Through experiments and simulation analysis, the strength design of square tubes can be further verified and optimized.
In summary, determining the strength of square tubes requires comprehensive consideration of multiple factors and the use of appropriate calculation formulas and experimental methods for estimation and verification.
Q: How to choose the coating for 4x4 Square Tube?
A: At Yuantai Derun, our purchasers should consider the application environment of different square tubes when selecting coating. Generally, they are arranged in descending order of corrosion resistance strength: black carbon steel square tube<pre galvanized square tube<zinc aluminum magnesium coated square tube<hot-dip galvanized square tube.
