precision steel tubes, they are made
from cold rolled steel that is galvanized
using the Sendzimir process. During Approvals VdS, FM, FG, CNBOP, SBSC, SETSCO, UL, cUL
this process zinc is brought onto the
metal strip, running through a zinc bath,
covering both sides simultaneously. The Tolerances According to EN 10305-3
