Plan your order
Material & processing
Plate thickness, width and length; cut size if required. Include the grade or describe your intended use if it is not yet selected.
Quantity & timing
Share your required tonnage and delivery date. Ask for stock availability, minimum order quantity and the dispatch schedule for your exact specification.
Packing & documents
Include destination, handling limits and required inspection documents so they can be reviewed with the material quotation.
Product details
Hot rolled steel plate enquiries range from full-size structural plates to cut pieces for fabrication and machinery. Start with the specified grade and standard, then list thickness, width, length and quantity for each size. This page brings together plate dimensions and grade-specific tables; use the individual A36, Q235B and S355JR pages when your project already names a grade. Cutting, surface preparation and inspection requirements should be included in the same quotation.
Flat plate for structural fabrication and industrial components. Specify the grade, thickness and cutting dimensions for your application.
Supply availability and the final specification are confirmed in the quotation. Please include the intended application, dimensions, quantity and destination when contacting us.
Cutting & fabrication
Specify the final plate size and downstream cutting or welding process.
Thickness & flatness
Define nominal thickness and the tolerances your fabrication requires.
Material documentation
Match the requested material standard with the inspection document.
Typical application

Frequently asked questions
What information is needed for cut-to-size hot rolled steel plate?
Provide a cutting list or drawing with finished dimensions, quantity per piece and tolerances. Identify the required grade, plate thickness, edge condition and any machining allowance. State whether the quotation should include cutting and surface preparation, as well as the full plate or finished-piece weight basis.
How do I choose between A36, Q235B and S355JR plate?
Use the grade required by your drawing or project specification. Compare the relevant thickness-dependent mechanical properties, chemistry, delivery condition and inspection requirements. These grade names refer to different standards and should not be treated as automatic substitutes.
Which details should match when comparing hot rolled plate prices?
Compare the same grade, thickness, plate size, delivery condition and quantity. Check the scope of cutting, testing, documents, protective packing and freight terms. Confirm material availability for the complete size list with the quotation.
How are minimum order and lead time confirmed?
Send your grade, size, tonnage and required delivery date. Ask for separate confirmation of stock availability, any production or processing time, and the dispatch date. Transit time depends on destination and shipment terms; the agreed quotation should state the minimum quantity and schedule.
What documents should I request?
List the required material test report, inspection document type and any third-party inspection in your enquiry. Ask which documents apply to your selected material and agree their scope before ordering. A general company certificate does not replace the material test results for the supplied heat or coil.
