Product Details
Ideal for tubular structures and poles, ASTM A871 is a structural steel with corrosion resistant properties.
Overview
1. Ideal structural steel for tubular structures and poles.
2. Available in two grades: 60 and 65.
3. Can be made to three types of chemical requirements: Type I, Type II and Type IV.
4. May be provided as-rolled, normalized or quenched and tempered.
5. Has atmospheric corrosion resistance and can be used in bare or unpainted conditions.
6. Thicknesses greater than 1 1/4" may be special ordered, but are not regularly stocked in our distribution centers.
