Application of Steel in the Construction Industry and SHUNGE STEEL's Market Contribution

In the construction industry, steel plays a vital role as a fundamental material, with various categories each serving unique functions. Different construction projects have strict requirements for the performance and specifications of steel, with the types of steel used in construction needing to meet specific standards.

Commonly Used Steel Categories and Standards in the Construction Industry:

• Rebar

Rebar is one of the most widely used steel materials in the construction industry. It features longitudinal and transverse ribs on its surface, which greatly enhances its bond with concrete, allowing them to work together efficiently to withstand various loads imposed on buildings. In building structures, rebar is primarily used in constructing the main framework, such as beams, slabs, and columns, ensuring the stability and safety of the structures.

In terms of standards, the production of rebar must adhere to a series of strict specifications. Taking China as an example, the execution standard is GB/T 1499.2-2018 "Steel for the Reinforcement of Concrete - Part 2: Hot-Rolled Ribbed Bars." This standard specifies the dimensions, appearance, weight, and allowable deviations of rebar. It defines parameters such as the internal diameter, transverse rib height, and longitudinal rib height for rebar of different nominal diameters. The standard also requires that rebar have both longitudinal and transverse ribs, with the transverse rib spacing not exceeding 0.7 times the nominal diameter. Weight deviations are also specified to ensure consistent product quality. Additionally, strict requirements are set for the mechanical properties of rebar, including yield strength, tensile strength, elongation after fracture, and maximum total elongation, among others. Different grades of rebar, such as HRB400 and HRB500, correspond to different standard values for mechanical properties. The selection of the appropriate grade of rebar depends on the specific design requirements of the construction project, ensuring structural safety and reliability.

• Wire Rod

Wire rod, also known as coil rod, refers to round steel with a smaller diameter and is generally supplied in coils. Due to its excellent flexibility and processability, wire rod finds wide application in the construction industry. A common standard for wire rod is GB/T 701-2008 "Carbon Structural Steels," which specifies the dimensions, appearance, weight, and allowable deviations for low-carbon steel hot-rolled wire rod. The standard defines parameters such as diameter tolerances for wire rod of different nominal diameters. In terms of performance, wire rod must meet mechanical properties such as tensile strength and elongation after fracture. There are also strict requirements for its chemical composition, ensuring the stability of quality and processability in construction applications.

• Medium and Thick Plates

Medium and thick plates refer to steel plates with thicknesses ranging from 4.5mm to 200mm. In the construction industry, medium and thick plates are mainly used to manufacture large structural components and building equipment. For instance, in high-rise steel structure buildings, medium and thick plates are used for constructing crucial structural elements such as beams and columns. With their higher strength and excellent load-bearing capacity, medium and thick plates meet the requirements for large-scale structures subjected to significant loads.

There are numerous execution standards for medium and thick plates, such as GB/T 709-2019 "Dimensions, Shape, Weight and Permissible Deviation for Hot-Rolled Steel Plates and Sheets," which specifies the dimensions, appearance, and weight deviations, among other aspects. In terms of performance standards, different steel grades and applications have corresponding requirements for the mechanical properties, process performance, and chemical composition of medium and thick plates. For example, Q345 series medium and thick plates used in building structures must meet specific indicators for yield strength, tensile strength, impact toughness, as well as strict limits on the content of carbon, manganese, silicon, and other chemical elements. These measures ensure the safety and reliability of medium and thick plates in construction applications.
