Answers

  • Is coiled rebar a type of wire rod or rebar?

    Coiled rebar is a type of rebar, referring to ribbed steel bars with spiral transverse ribs on their surface. It also refers to rebar coiled together like a wire rod. Coiled rebar is generally thread-shaped, with diameters of 6.5mm, 8.0mm, 10mm, 12mm, and 14mm, etc. While rebar only comes in diameters of 9-12mm, coiled rebar can be cut to any desired size.

    Rebar is hot-rolled ribbed steel bar, mainly used as the framework for reinforced concrete building components. It requires certain mechanical strength, bending deformation performance, and weldability. The raw material for producing rebar is carbon structural steel or low-alloy structural steel that has undergone refining and smelting. The finished rebar is delivered in hot-rolled, normalized, or hot-rolled condition. It is generally in straight bar form.

    Wire rod is the type of hot-rolled steel with the smallest cross-sectional area. Wire rod is delivered in coils, hence the name "coiled bar." Wire rod is generally round, with diameters typically ranging from 5 to 9mm.


  • What are the commonly used mesh sizes for rebar mesh?

    Rebar mesh is a robust reinforcing mesh structure formed by welded links of rebars. Common mesh sizes include: Type A: 20mm*20mm, Type B: 10mm*20mm, Type C: 15mm*20mm, Type D: 10mm*10mm, Type E: 15mm*15mm, and Type F: 10mm*15mm. The diameter of the rebar mesh is typically 4-14mm. The maximum width is 2.4 meters, and the maximum length is 12 meters.
    The calculation formula is: Weight of rebar = Length of rebar * Specific gravity of rebar. Therefore, reinforcing mesh can be used to calculate the weight of rebars. The total length of rebars with different diameters multiplied by their respective specific gravity gives the total weight of the rebars, which is actually the theoretical weight.


  • What are the applications of tinplate products?

    Tinplate (tin-plated steel) is primarily used in food and beverage packaging, such as cans, milk powder tins, and beverage bottle caps. It is also widely used in industrial containers for chemicals, paints, and aerosols, as well as in hardware and electronic products such as battery casings and electronic components. In addition, it is commonly used in gift boxes, tea tins, toys, and other daily necessities.
