Hot-dip galvanized steel rod is identified with Q235B and ASTM A36 material requirements for equipment fabrication.

Specify the solid bar

Choose one grade and an 18mm or 36mm finished-size requirement. Define the actual section and tolerance instead of treating every round, square or threaded form as identical.

• Q235B grade requirement.
• ASTM A36 material request.
• 18mm size requirement.
• 36mm diameter alternative.
• Hot-dip galvanized finish.

Define the cutting order

Provide length, end condition and component-drawing acceptance for the selected rod.

Request batch evidence

Obtain chemistry, dimensional and coating inspection before fabrication. Wide-coil or sheet-thickness descriptions do not specify a solid rod. General quality and corrosion wording does not establish structural capacity, coating life or compatibility with every equipment assembly.
