Best mild steel plates do more than meet specifications — they make fabrication easier, welding smoother, and inspection faster. Whether you are building a structure, fabricating machinery, or manufacturing tanks, the quality of your plate decides how efficiently your project moves. This guide explains what makes a mild steel plate the best choice, which grades to look for, and how Namco Industries delivers quality that stands out in the Indian and global market.
What makes a mild steel plate
Not all plates are equal. The best plates combine chemistry consistency, dimensional accuracy, and clean documentation.
-
Consistent composition – Controlled carbon and manganese levels ensure stable strength and weldability.
-
Tight thickness and flatness control – Saves hours in fit up and machining.
-
Smooth surface finish – Easier to paint and weld with minimal cleaning.
-
Reliable mechanical properties – Predictable yield and tensile values help engineers design safely.
-
Traceable documentation – EN 10204 Type 3.1 certificates build confidence during audits.
-
Ready-to-fabricate – Shot blasted and primed plates reduce prep time on site.
Common grades of the best mild steel plates
IS 2062 E250 – The standard choice for structural and general fabrication work.
IS 2062 E350 – Higher strength for lighter, more efficient designs.
ASTM A36 – Common in global projects and mixed-standard environments.
EN 10025 S235 / S275 – European equivalents widely accepted in export fabrication.
