Product Application Scenarios

Material Type	Specific Uses
Low Carbon Steel (C ≤ 0.25%)	- Building structures (e.g., bridges, house frames). - Car body panels. - General machinery parts (e.g., bolts, nuts). - Packaging materials (e.g., steel drums, containers).
Medium Carbon Steel (C: 0.25%-0.60%)	- Machinery parts (e.g., shafts, gears, connecting rods). - High-strength structural components. - Tools (e.g., wrenches, hammer heads). - Railway wheels.
High Carbon Steel (C ≥ 0.60%)	- Cutting tools (e.g., blades, scissors). - Springs (e.g., suspension springs). - High-strength wires. - Wear-resistant parts (e.g., bearings, molds).
Alloy Steel (with Cr, Ni, Mo, etc.)	- High-strength machinery parts (e.g., gears, axles). - Automotive components (e.g., crankshafts). - Aerospace parts (e.g., landing gear). - Oil drilling equipment (e.g., drill pipes).
Tool Steel (with high hardness)	- Cutting tools (e.g., drill bits, milling cutters). - Molds (e.g., stamping dies, injection molds). - Wear-resistant parts (e.g., punches, shear blades).
Spring Steel (high elasticity)	- Springs (e.g., car suspension springs, mechanical springs). - High-elasticity components (e.g., clutch springs). - High-strength wires (e.g., piano wires).
Heat-Resistant Steel (high temp use)	- Boilers and pressure vessels. - High-temperature pipelines. - Heat exchangers. - Petrochemical equipment (e.g., reactors, furnace tubes).

FAQ

Q: How is the packaging of steel coil to ensure safe transportation?

A: Anti-rust paper, waterproof material and steel belt are used to fix the steel coil to ensure that the steel coil is not damaged during transportation.

Q: Can the size of the steel coil be customized?

A: Yes, we can provide customized size steel coils according to customer needs.

Q: What is the difference between hot-rolled steel coil and cold-rolled steel coil?

A: Hot-rolled steel coil is rolled at high temperature, with a rougher surface and thicker thickness; cold-rolled steel coil is rolled at room temperature, with a smoother surface, thinner thickness and higher precision.

Q: How long is the lead time for hot rolled steel coils?

A: The lead time depends on the order quantity and customization requirements, usually 7-15 days.

Q: What is the weight of a single hot rolled steel coil?

A: The weight of a single hot rolled steel coil depends on the thickness, width and length, usually between 4tons-6tons,6tons-8tons,8tons-12tons. The specific weight can be customized according to customer needs.
