FEATURE|The Analysis of the Development Status of Steel Market in Shandong Province(China)

Affected by the terminal market, domestic steel demand will continue to be sluggish, which will lead to inventory backlogs. Therefore, merchants generally begin to seek overseas orders. Domestic steel prices are in the global price trough, and the RMB exchange rate is still hovering at a low level, making China's steel exports more cost-effective.

FEATURE|Comparison of Common Mold Steel Grades in China and Other Countries

Mold steel is a type of steel used to make molds, such as cold stamping dies, hot forging dies, and die-casting dies. Molds are the main processing tools for manufacturing parts in industrial sectors such as machinery manufacturing, radio instruments, motors, and electrical appliances. Since the production standards of various countries are different, this has caused certain difficulties for customers in international trade. CSMC will organize and display the Chinese grades and other countries' grades to help customers conduct trade more smoothly.

FEATURE|The Brief Summary of Common Container Knowledge

Container refers to a large loading container with a certain strength, stiffness, and specifications specially designed for turnover use. The characteristics of containers are that they have a uniform format and can be stacked layer by layer. Therefore, they can be placed in large numbers on ocean-going ships. It can provide manufacturers around the world with high-volume shipping services that are cheaper than air freight.

Answers

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.
What are fixed length and random length. If I need 12-meter steel pipes, can you guarantee the exact length?
Fixed Length: This refers to production or cutting to a fixed length as required by the buyer's contract. For example, if you need 12 meters, the steel mill will roll or cut to the target length of 12 meters.
Random length: This refers to the natural length produced by the steel mill based on maximizing production efficiency (e.g., randomly between 6 and 12 meters), without a commitment to a specific size.

We can guarantee the length of the steel pipes, but the definition of "full length" needs to be clearly stated in the contract. Length tolerances must be agreed upon. because hot cutting and cooling shrinkage can introduce minute errors. Before shipment, we will conduct a re-inspection according to the sampling ratio specified in the contract, including key dimensions such as length, wall thickness, and outer diameter, ensuring that only qualified products are loaded.
To avoid disputes, we recommend clearly stating in the contract: "Length 12 meters, execution standard, and tolerances." Through self-operated or regulated procurement via the CSMC platform, conduct sampling inspections according to standards before shipment to ensure that the length of each steel pipe conforms to the agreement.
