3/8″ 1×7 Guy Wire for Towers

This 3/8″ 1×7 guy wire is designed for tensioning, bracing, and structural support applications where maximum strength and minimal stretch are required. Manufactured from Extra High Strength (EHS) steel and protected with a galvanized finish, this guy strand provides dependable performance for securing communication towers, antennas, utility poles, and other freestanding structures.

High-Strength Guy Wire for Tower & Structural Bracing

The 1×7 construction consists of seven wires formed into a single strand, creating one of the stiffest guy wire configurations available. Its low flexibility and high tensile strength make it ideal for applications where maintaining tension and structural stability is critical. Common uses include tower guying, utility support systems, antenna stabilization, and structural bracing.

1×7 Guy Strand Configuration

Our guy wire is manufactured from EHS-grade steel. EHS (Extra High Strength) steel delivers approximately 40% greater tensile strength than HS-grade steel, resulting in improved breaking strength and enhanced load-carrying performance.

The class of this cable is 1×7. The first number indicates a single strand construction, while the second number refers to the seven wires that make up the strand. This configuration provides exceptional tensile strength with very little stretch or flexibility.

Galvanized Finish

This guy wire features a protective galvanized coating that helps resist corrosion and environmental exposure. The galvanized finish extends service life in outdoor applications and provides dependable performance in challenging weather conditions.

Installation Tips

• Use properly sized guy wire hardware, grips, and anchors designed for 3/8″ cable.
• Inspect wire regularly for corrosion, abrasion, or damage in exposed environments.
• Maintain proper tension according to structure and engineering requirements.
• For applications requiring greater flexibility or improved resistance to compressive forces, consider a 1×19 guy wire construction.

Wire Rope by the Foot Ordering FAQ

Will my wire rope arrive as one continuous length?
Yes. The quantity you order will be supplied as one continuous, uncut length of wire rope. For example, if you order a quantity of 1,000, you will receive a single 1,000-foot length.

Can I order multiple separate lengths?
Yes. To receive multiple lengths, add each length to your cart as a separate line item. For example, if you need two 1,500-foot lengths, enter a quantity of 1,500 and add it to your cart twice. Each line item will be cut and supplied as a separate length.

Can I order lengths shorter than the minimum order quantity if the combined total exceeds the minimum?
Yes. If your combined order will exceed the minimum quantity requirement but you need shorter individual lengths, please call our team to place your order. One of our product experts will be happy to assist.
