Product Overview

Construction Carbon Steel Plate Sheet is manufactured according to international standards such as ASTM, EN, JIS, and GB, providing reliable strength, good weldability, and excellent fabrication performance.

Due to its balanced mechanical properties and cost efficiency, carbon steel plate remains one of the most commonly specified materials in construction and structural engineering worldwide.

Product Details

Typical Mechanical Properties

Mechanical properties vary depending on the steel grade and applicable standard. Typical values for commonly supplied construction carbon steel plates are shown below:

Property	ASTM A36	S235JR	SS400	Q235B
Yield Strength	≥250 MPa	≥235 MPa	≥245 MPa*	≥235 MPa
Tensile Strength	400–550 MPa	360–510 MPa	400–510 MPa	370–500 MPa
Elongation	≥20%	≥26%	≥21%	≥26%
Impact Test	Optional	27J @ +20°C	Optional	Optional

Typical value depending on thickness.
Actual values are supplied according to the relevant standard and verified through Mill Test Certificates (MTC).

key Performance

Thickness tolerances comply with ASTM A6, EN 10029, or customer-specific requirements, typically ranging from ±0.25mm to ±0.5mm depending on plate thickness.

Plates undergo shot-blasting and automatic priming to remove mill scale and enhance paint adhesion for outdoor use.

Heavy-thickness plates are available with ultrasonic testing (UT) to verify internal integrity for high-stress structures.

Consistent flatness and predictable chemistry prevent cracking or warping during laser cutting and heavy bending.

Packaging & Delivery

FAQ

Q: What is your Minimum Order Quantity (MOQ)?

A: For standard sizes in stock, there is no MOQ. For customized sizes or specific steel grades, the MOQ is typically 5 to 10 tons per specification.

Q: Can you provide free samples and Mill Test Certificates (MTC)?

A: Yes. We offer free small material samples (courier cost covered by the buyer) and always provide a real EN 10204 3.1 MTC before or upon delivery to verify chemical and mechanical properties.

Q: How do you handle quality disputes or weight shortages after arrival?

A: We take 100% responsibility. If any quality issue or weight shortage is verified by a third-party report within 30 days of port arrival, we will issue a replacement, discount, or refund within 7 working days.

Q: Do you support customized cutting and surface treatment?

A: Yes, absolutely. We provide full processing services, including precision laser/plasma cutting, bending, shot-blasting, and anti-rust priming strictly according to your CAD drawings.

Q: What is your typical production and delivery lead time?

A: In-stock items: Ready for shipment within 3–7 days.
Custom production: Usually takes 15–25 days depending on the order volume and steel mill schedule.

Q: What standards can your construction steel plates comply with?

A: Our construction carbon steel plates can be supplied according to ASTM, EN, JIS, GB, DIN, and other international standards. Material certificates and inspection reports are available upon request.
