ABSTRACT:
It is a method of treatment of support rods for the support of steel reinforcements in making aerated concrete, in which the support rods are first dipped into a hot bath of molten paraffin or a similar wax-like, waterproof material, which is solid at room temperature and has a softening temperature of about 50.degree. to 70.degree. C. Then the coating formed thereby is hardened by cooling. Then the steel reinforcements are suspended on the support rods and they, together with the support rods are coated with a corrosion protection medium in the form of a water-lacquer.
