Tension Spring - Galfan Coating

Maintain Consistent Wire Tension Through Temperature Changes — Galfan-Coated Tension Spring

The Tension Spring with Galfan Coating is an in-line fence spring designed to absorb the expansion and contraction of hi-tensile wire as temperatures change through the seasons. Without a tension spring, temperature swings cause hi-tensile wire to go slack in summer heat and dangerously tight in winter cold — stressing posts, strainers, and the wire itself. The tension spring compensates automatically, keeping your fence at consistent tension year-round without manual adjustment.

Galfan coating provides superior corrosion resistance compared to standard galvanizing — a zinc-aluminum alloy that outperforms hot-dip galvanizing in long-term outdoor exposure, particularly in wet or coastal environments. Install one spring per wire run for consistent tension management across the full fence line.

Features

In-Line Tension Management
Absorbs wire expansion and contraction from temperature changes — keeps fence tension consistent year-round without manual adjustment.

Galfan Coating
Zinc-aluminum alloy coating provides superior corrosion resistance over standard galvanizing — longer service life in outdoor and wet conditions.

Protects Fence Infrastructure
Reduces stress on posts, strainers, and wire from seasonal tension changes — extends the life of your entire fence system.

Hi-Tensile Compatible
Designed for use with hi-tensile wire fence systems where temperature-driven tension changes are most significant.

Specifications

• Type: In-line fence tension spring
• Coating: Galfan (zinc-aluminum alloy)
• Application: Hi-tensile wire fence systems — one spring per wire run

Set it and forget it — the Galfan-coated Tension Spring keeps your hi-tensile fence at consistent tension through every season without manual adjustment.
