Line Hardware is a Women-Owned and Operated family business organized in 1970 that produces custom and standard line products in steel, iron, copper, bronze and aluminum for the line construction industry. We offer a broad line of standard products regularly used for distribution line construction. Many of these commonly used Line Hardware products are kept in stock in order to meet the occasional critical needs of our customers. We are also experienced manufacturers of special materials and capable of meeting the unique requirements of the individual power companies we serve. From standards clamps and fasteners, to special brackets and adapters, we are able to deliver the products you need when you need them.
To insure quality finished products we start with quality raw material and use the best, most practical, manufacturing processes available. Ferrous castings are made of ductile iron, grade 654512, which provides higher strength and greater elongation than other cast irons. Steel products are made of domestically sourced hot rolled steel, typically A-36. Bronze and aluminum alloy products are made of the grade most suitable for the product, considering the electrical conductivity, strength and machinability required. Copper products are made of C110 Copper Electrolytic Tough Pitch.
Hot dip galvanizing is the industry accepted solution to corrosion of ferrous line hardware. The products of LHI are galvanized in accordance with the latest revision of the ASTM A-153 standard for zinc coated steel and iron hardware. After fabrication, each part goes through a ten step process in modern galvanizing facilities to provide the best possible finish. A visual inspection of the cooled parts is performed to ensure complete coverage. Random testing with a hand held magnagauge is performed to check for proper mil thickness.
