Product Introduction

Technical Specifications & Selection Parameters

Our Preformed Dead-End Guy Grips comply with recognized international standards, including ASTM A475, ASTM B416, IEC 61284, and BS 183.

Parameter	Key Requirements & Checks
Guy Strand Diameter	Verify nominal and exact actual diameter tolerances.
Strand Construction	Number of wires and configuration (e.g., 1x7, 1x19).
Strand Material	Galvanized steel, aluminum-clad steel, or specified alloy.
Surface Coating	Class A, B, or C zinc coating, or aluminum cladding specification.
Strand Grade	Required mechanical grade (e.g., EHS / Extra High Strength).
Lay Direction	Left-hand lay (LHL) or right-hand lay (RHL) matching outer strand layer.
Holding Strength	Rated breaking strength (RBS) and required efficiency percentage.
Dimensions	Specified applied length and overall formed length.
End Configuration	Cabled loop, offset loop, or specialized terminal geometry.
Identification	Color code bands, center mark, and part markings.

Key Product Features & Application Benefits

Stress Distribution:

Uniformly distributes holding tension along the strand to prevent stress concentration and wire deformation.

Tool-Free Installation:

Engineered for fast, manual wrapping without hydraulic crimpers or specialized torque tools.

Corrosion Resistance:

Available in heavy galvanized steel (ASTM A475 Class A/B/C) and aluminum-clad steel (ASTM B416) to eliminate galvanic corrosion risks.

Secure Anchoring:

Ideal for stabilizing utility poles, transmission towers, telecommunication masts, and fixed structural guy assemblies.

Manufacturing & Quality Control

Raw Material QC: Wire diameter tolerances, tensile strength, elongation, and coating thickness are tested upon receipt with full Material Test Reports (MTRs).

Helical Forming: CNC-controlled pitch and diameter forming ensure geometry precisely matches the target strand.

In-Process Audit: First-piece inspection confirms pitch, wrap tightness, and crossover alignment before batch production.

Tensile Testing: Mechanical holding verification ensures full load transfer up to specified rated breaking strength.

RFQ Checklist

Confirm the following details before submitting your inquiry:
• Nominal and actual strand diameter
• Strand construction and lay direction
• Strand material and coating class
• Required holding load / Rated Breaking Strength (RBS)
• Loop configuration and packaging requirements

FAQ

Q: How do I select the correct Preformed Dead-End Guy Grip?

A: Selection must be based on the exact guy strand specification rather than nominal diameter alone. Confirm the actual diameter, construction (e.g., 1x7 vs. 1x19), material grade, coating class, lay direction, and required holding load against engineering specifications.

Q: Can a single grip fit different strand constructions of the same diameter?

A: No. Strands with identical nominal diameters can vary in actual outer diameter and surface pitch based on construction. Using an unmatched grip may result in reduced holding capacity or cable slippage.

Q: What wire materials are available?

A: Standard options include heavy galvanized steel wire (ASTM A475) and aluminum-clad steel wire (ASTM B416). Material must match the strand to prevent galvanic corrosion and ensure mechanical compatibility.

Q: How is holding performance verified?

A: Performance is verified through mechanical tensile testing on the specified guy strand assembly, confirming the grip meets or exceeds the required percentage of the strand's rated breaking strength without slippage.

Q: Are custom configurations available for utility projects?

A: Yes. Custom pitch lengths, wire gauges, end loops, color coding, and batch markings can be manufactured to match utility standards or custom engineering drawings.
