Our flat steel products are widely utilized across various industries:
Advanced high-speed rolling and controlled cooling technologies ensure dimensional precision (±0.1 mm) and microstructural homogeneity, supporting downstream processes like drawing and heat treatment. Material selection must comply with industry standards (ASTM, GB/T, JIS), prioritizing carbon content, elongation, and surface defect control.
What are the common thicknesses of flat steel available?
Hot-rolled flat steel is available in 1.5–60 mm, while cold-rolled flat steel typically ranges from 1–16 mm.
What is the difference between hot-rolled and cold-rolled flat steel?
Hot-rolled steel is processed at high temperatures with a rougher surface, whereas cold-rolled steel is processed at room temperature, offering a smoother surface and higher dimensional accuracy.
Is the length of the flat steel customizable?
Yes, while the standard length is 6 meters, we can customize the length based on your project requirements.
Which materials are commonly used for these products?
We commonly use common carbon steel (Q235, A36), medium carbon steel (45 Steel), stainless steel (304, 316), and alloy steel (40Cr, 42CrMo).
What are the primary applications of flat steel?
It is widely used in construction, machinery, automotive chassis, shipbuilding, bridge structures, and furniture frame manufacturing.
