HFW Black Square Tube: Get a Quote for Square Hollow Section (SHS) Steel Profiles
1.Quote for Square Hollow Section(SHS) Profiles
Firstly, the square hollow section offer is not set in stone, this is determined by the price fluctuation of steel. In the source of tdr group. Our quotation for square hollow section is determined by the current raw material and processing cost of steel plate. Of course, the quotation of square hollow section you get includes the lifting fee, port charges, freight, and our small profit.
2.Square Hollow Section (SHS) Steel Profiles performances
The mechanical properties of large-diameter square hollow sections are important indicators to ensure the ultimate performance (mechanical properties) of large-diameter square steel pipes, which depend on the chemical composition and heat treatment system of the steel pipes. So according to different usage requirements, the mechanical properties of large diameter square hollow sections are specifically introduced from the aspects of tensile strength, yield point, and elongation.
1 Tensile strength
The maximum force (Fb) that the specimen bears during the tensile process at break, obtained from the original cross-sectional area (So) of the specimen( σ), Called tensile strength( σ b) , in N/mm2 (MPa). It represents the maximum resistance of metal materials to failure under tensile force.
2 yield point
The stress at which a metal material with yield phenomenon can continue to elongate without increasing (maintaining a constant) force during the tensile process is called the yield point. If the force decreases, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2 (MPa).
3. Elongation after fracture
In the Tensile testing, the percentage of the increased length of the gauge length and the original gauge length after the sample is pulled off is called the elongation. with σ Represented in%.
3.Square Hollow Section (SHS) Steel Profiles classification
1. There are two types of square steel pipes based on material: ordinary carbon structural steel square steel pipes and low alloy high-strength structural steel square hollow section(SHS)steel profiles;
2. According to professional purposes, it is divided into oil well pipes (casing), pipeline pipes (boiler pipes), mechanical construction pipes, etc;
3. According to the cross-sectional shape, there are four types: circular, square, rectangular, and irregular. The performance of Yuantai Derun square rectangular tube is better;
4. Various non-standard rectangular tube products can be customized according to user requirements.
