Specifications
Mild Steel Sheet
Carbon Steel Plate Hot Rolled and Cold Rolled
Low carbon plate in 0-100mm for building frames bridge members and fabrication work
Carbon steel plate is a low carbon flat rolled product supplied hot rolled or cold rolled in 0-100mm thickness. It is specified by structural fabricators and civil contractors who need plate for building members bridge work and road repair platforms. Ordering it cut to size removes the offcut that a fabrication shop otherwise pays for, stores and eventually scraps. The grade list covers S235 S235JR S335 SS400 ST37 ST52 E250 E350 and SM400 so several drawing callouts can be filled from a single order.

Why It Is Specified
Key Benefits of Carbon Steel Plate
Bends Without Cracking at the Radius
Bending strength is not high and the plate falls in the easily bendable category. Press brake work goes through without the edge cracking you get on higher strength plate.
Welds With the Procedure You Already Run
Low carbon content keeps the plate easy to weld. Your shop can fit it using the filler and procedure already qualified for mild steel instead of writing a new one.
Several Standard Grades From One Order
S235 S235JR S335 SS400 ST37 ST52 E250 E350 and SM400 come from the same supply so a mixed drawing package does not need separate suppliers for European Japanese and Indian grade callouts.
Hot Rolled or Cold Rolled to Suit the Job
Hot rolled plate suits heavy structural members and cold rolled suits work where surface and dimensional consistency matter more than section thickness.
Plate Arrives Ready to Fit
Bending welding decoiling cutting and punching are done before shipment so panels and gussets land at your bay ready to assemble.
Grade Documented on Paper
A mill test certificate is issued against the ordered grade so the plate can be signed into a building or bridge inspection file.
Problems It Solves
What This Material Removes From Your Process
Paying for Offcut You Cannot Use
Ordering full plates to make small parts leaves drops that occupy rack space and go to scrap. Cut to size supply against your cutting list sends only the pieces on the drawing.
Chasing Three Suppliers for Three Grade Callouts
European Japanese and Indian designations often sit on the same drawing package. S235 SS400 ST37 E250 and SM400 come from one supply so the package is filled in a single order.
Plate That Cracks on the Press Brake
Higher strength plate cracks at the bend line when the radius is tight. Low carbon plate is in the easily bendable category so formed parts come off the brake intact.
Missing Grade Documentation at Inspection
Structural and bridge work needs the grade on paper. The mill test certificate ships with the material so the inspection file is complete when the plate arrives.
Application Scenarios
Where It Is Used
Structural Members in Buildings
Base plates gussets stiffeners and connection plates that add strength and support to a steel building frame.
Bridge Fabrication
Plate for girder webs flanges and splice plates on road and pedestrian bridge work.
Road Repair Platforms
Temporary trench covers and running plates laid over excavations during road repairs.
General Fabrication Shops
Brackets frames skids and mounting plates cut from stock plate for mixed job shop work.
Formed and Bent Components
Channels trays covers and folded sections where the plate has to take a bend without edge cracking.
Painted Structural Assemblies
Work where the plate is supplied painted so the fabricator does not have to prime it before shipping the assembly.

Comparison
Carbon Steel Plate Against the Alternatives
| High strength low alloy plate | Carbon plate bends and welds more easily because the bending strength is lower, which suits connection plates and formed parts more than weight critical members. |
|---|---|
| Stainless steel plate | Carbon plate is the cheaper choice for painted structural work where the environment does not demand corrosion resistance. |
| Structural section such as channel or angle | Plate lets you cut any profile you need instead of designing around the shapes a rolling mill offers. |
Use Guide
Specifying Handling and Welding Notes
- State the grade designation from your drawing so the right equivalent is matched at order entry
- Choose cold rolled where surface and thickness consistency matter and hot rolled for heavier structural sections
- Bend across the rolling direction where the part allows and keep the inside radius generous on thicker plate
- Specify painted surface if the plate will sit outdoors between delivery and fabrication
- Send the cutting list with the order so plate arrives as finished parts rather than full sheets
- Ask for the mill test certificate at order stage so it ships with the material
Questions Buyers Ask
Carbon Steel Plate FAQ
What thickness can you supply in carbon steel plate?
Thickness runs from 0 to 100mm and size is cut to your requirement. Tell us the plate sizes on your cutting list rather than a standard sheet size.
Which grades do you hold?
S235 S235JR S335 SS400 ST37 ST52 E250 E350 and SM400. If your drawing names a grade not on that list, send the chemistry and mechanical requirement and we will confirm the nearest match.
Is the plate hot rolled or cold rolled?
Both are available. Cold rolled is the usual choice where surface and thickness consistency matter and hot rolled covers the heavier structural sections.
Can you cut and bend the plate before shipping?
Yes. Processing covers bending welding decoiling cutting and punching, so parts can arrive formed and drilled ready for assembly.
Do you supply a mill test certificate?
Yes. A mill test certificate is issued against the ordered grade and travels with the shipment for your inspection file.
Can we see a sample first?
Samples are available. Confirm the grade thickness and surface you want to check and we will advise what can be released.
Is the plate painted or bare?
Surface is supplied natural or painted. Painted is worth specifying if the plate will be stored outdoors before fabrication.
