DeMuth Steel Products, Inc. products

Cold-forged thread. Heavy Electro-Zinc Galvanizing on both rod and thread. Chromate treated for extra protection. Plating capabilities to 20`6" length. Rod diameters — 1/2", 9/16", 5/8", 11/16", 3/4" and 1". Time tested lug design permits full torque on rod. Special oversize nuts which compensate for galvanizing.

DeMuth produces tensioning rods up to 20` in length and in diameters from 1/2" to 1". Threads are cold-forged with a pointed end for easy hoop assembly and an exclusive graduated "lead-in" thread between the fully threaded and the plain portion of the rod - this eliminates the notch effect and the danger of reduced strength at this critical point where there is severe bending behind the lug during tensioning. Rods, including the threaded portion, are electro-zinc galvanized and finished with gold chromate for extra corrosion resistance. DeMuth tensioning rods are specially bundled for ease of handling.

Strong, durable weather-tight roofs for all circular structures. Maintenance free for decades due to galvalume. Poly roof cap provides good daytime light inside the structure. Water runs off freely because of the height of the ribs.
