Home > Our Products > Carbon Steel Plates
Built for Strength. Trusted for Every Industry.
Whether you’re fabricating pressure vessels, constructing bridges, welding pipelines, or building structural frames — carbon steel plates offer the perfect combination of strength, affordability, weldability, and wide thickness range.
From low-carbon mild steel (like ASTM A36, IS 2062) to high-carbon grades for heat-treated applications, our range of plates covers it all. Supplied across India and exported worldwide, we support buyers with:
Whether you’re a manufacturer, EPC contractor, or OEM — this is your go-to guide for everything related to carbon steel sheet and plate supply.
Carbon steel plate is a flat-rolled steel product made primarily from iron and carbon, without significant alloying additions. Depending on the carbon content, these plates are categorized into:
Unlike stainless or alloy steel, carbon steel is more economical, easier to weld, and available in a broad thickness range — making it a preferred material for:
Carbon steel plates are manufactured as per ASTM, IS, EN, DIN, and JIS standards with additional options for surface finish, mill edge, tempering, or HIC/NACE testing for sour service.
Carbon steel plates are known for their versatility, cost-efficiency, and workability — making them a preferred choice across fabrication-heavy and load-bearing industries. Below are key commercial sectors where carbon steel plates play a central role
carbon plates protect your machinery, bottom-line, and team.
Carbon steel plates are categorized based on their carbon content, mechanical strength, and use-case certification standards. Here’s a breakdown of commonly available types along with their typical applications and equivalents.

Call, WhatsApp, or email our sales team—we respond within 30 minutes.
Not all steel plates with the same grade label are equal. Composition, tolerance, and testing certifications vary. Always ask for mill TC, compliance docs (ISO, IBR), and brand origin.
A36 is not the same as IS 2062 Grade B. SS400 ≠ S275. We often see rejections when plates are wrongly matched in EPC or international projects. Use our team’s help for exact grade mapping.
In precision fabrication or pressure vessel applications, a few mm off thickness = design failure. Always specify whether you need hot rolled tolerance, machined plates, or surface-finished plates.
High carbon vs. low carbon steel significantly affects weldability, forming, and service life. A cheaper per kg plate can lead to welding cracks, brittleness, or failure under pressure.
If you're sourcing for PSU tenders, offshore use, or pressure vessels, 3.1 / 3.2 certificates or IBR stamping are often mandatory. We provide these, but many stockists may not.
Steel delivery timelines affect entire project Gantt charts. Always confirm availability, lead time, and cut-to-size options upfront.
Always send us your spec sheet or past invoice if unsure. We'll suggest the best-fit plate — technically and commercially.
