What Is Steel Plate?

Steel Plate is flat rolled steel formed by continuous hot rolling or cold rolling of steel slabs, followed by leveling, surface finishing and fixed-length cutting processes. Every qualified Steel Plate features smooth steel plate surface, consistent steel plate thickness, neat steel plate cutting edges and dense internal metallographic structure of Steel Plate. Premium Steel Plate has no steel plate surface pits, no steel plate cracks, no steel plate warpage deformation and no internal segregation defects. Steel Plate possesses outstanding steel plate weldability, strong steel plate stamping performance, great steel plate bending and cutting capacity, which allows Steel Plate to undergo all kinds of secondary processing freely. Multiple surface treatment options are available for Steel Plate, including black hot rolled Steel Plate, pickled oiled Steel Plate, hot dipped galvanized Steel Plate, color coated Steel Plate and wear resistant Steel Plate. Different surface-treated Steel Plate can match indoor processing, outdoor construction, marine anti-corrosion and heavy wear working environments respectively. Each batch of Steel Plate will pass strict thickness tolerance, tensile and hardness testing to guarantee stable mechanical performance of Steel Plate during long-term production use.

Main Classifications of Industrial Steel Plate & Unique Features of Each Steel Plate

The global metal raw material market covers various mainstream Steel Plate categories, and each Steel Plate type is developed to meet exclusive industrial production and construction requirements.

1. Hot Rolled Steel Plate

Hot Rolled Steel Plate is the most mainstream bulk supply Steel Plate in the whole Steel Plate market. High-temperature continuous rolling endows Hot Rolled Steel Plate with thick stable internal grain structure, strong Hot Rolled Steel Plate impact toughness and outstanding plasticity. Hot Rolled Steel Plate has wide thickness coverage and low comprehensive cost, which makes Hot Rolled Steel Plate widely used for steel structure blanks, mechanical base plates, engineering foundation parts and general equipment shell raw materials. Stable supply and affordable price make Hot Rolled Steel Plate the first-choice bulk procurement Steel Plate for most engineering and processing enterprises.

2. Cold Rolled Steel Plate

Cold Rolled Steel Plate is high-precision thin finished Steel Plate processed by multi-pass cold rolling and annealing. Cold Rolled Steel Plate has ultra-smooth mirror surface, ultra-tight dimensional thickness tolerance and flatness far superior to Hot Rolled Steel Plate. Cold Rolled Steel Plate needs no secondary polishing, greatly reducing processing loss for precision hardware, electrical shell and decorative metal parts. Cold Rolled Steel Plate is the essential thin Steel Plate for high-standard precision manufacturing industries.

3. Galvanized Steel Plate

Galvanized Steel Plate is anti-corrosion upgraded Steel Plate covered with compact zinc coating via hot-dip galvanizing technology. The uniform zinc layer fully wraps every surface of Galvanized Steel Plate to isolate air, moisture and salt fog erosion, thoroughly solving the rust oxidation problem of ordinary carbon Steel Plate. Galvanized Steel Plate features long weather resistance service life, widely applied for photovoltaic accessories, outdoor cabinet shells, guardrail panels and long-term exposed structural Steel Plate components.

4. Checkered Steel Plate

Checkered Steel Plate is special anti-slip functional Steel Plate with raised pattern on the surface of Steel Plate. The convex patterns of Checkered Steel Plate greatly increase surface friction coefficient of Steel Plate, effectively preventing personnel and equipment slipping. Checkered Steel Plate is commonly used for workshop walkway flooring, truck bottom plates, stair treads and platform anti-slip Steel Plate projects.

5. Wear Resistant Steel Plate

Wear Resistant Steel Plate is high-hardness special Steel Plate with upgraded wear resistance index. Wear Resistant Steel Plate maintains stable hardness under long-term friction, impact and abrasion conditions, widely used for mining equipment lining, concrete mixer liners and heavy machinery wear-resistant structural Steel Plate parts.

6. Carbon Steel Plate

Carbon Steel Plate represented by Q235B, S235JR and SS400 is universal standard Steel Plate for most industrial scenarios. Carbon Steel Plate has balanced ductility, stable weldability and moderate hardness, easy to cut, weld and stamp. Carbon Steel Plate can adapt to most conventional construction and metal processing demands, becoming the most cost-effective general Steel Plate for mass procurement.
