Description
Reliable General Purpose Security and Restraint
Securing commercial grounds, warehouse loading bays, and trade yards requires dependable hardware that can cope with harsh weather and everyday physical strain. When perimeter security fails or temporary barriers fall short, facilities face unmanaged traffic, inventory shrinkage, and ongoing safety hazards. Selecting an insufficiently protected chain often leads to premature surface corrosion, seizure of moving links, and frustratingly frequent replacements.
The 300/Z (3442-219) Bzp 6.5 X 36Mm Long Link Chain provides a practical, robust solution designed to address these daily perimeter challenges. Fabricated with an extended link profile and treated with a brilliant bright zinc plated finish, this chain combines physical strength with clean handling and enhanced rust resistance. It offers maintenance teams, agricultural operators, and commercial facilities managers an adaptable hardware choice for demanding environments across the UK.
Key Operational Advantages
Extended Link Geometry
The elongated 36mm internal pitch ensures hassle-free integration with various fittings. You can easily feed wide shackle padlocks, carbine hooks, clevis pins, and heavy-duty shackles through the inner link clearance without tight binding or excessive leverage strain.
Protective Bright Zinc Plating
Every link undergoes uniform electro-galvanising to produce a protective zinc barrier. This smooth sacrificial coating repels surface corrosion, guards the core steel from moisture, and prevents oily residue from transferring onto hands or equipment during daily handling.
Balanced Core Strength
With a sturdy 6.5mm wire gauge, this chain delivers excellent tensile capacity and strong resistance to standard manual bolt croppers. It keeps overall run weights manageable for operators who regularly wind, stow, or adjust safety barriers across broad site spans.
Smooth Tangle-Free Articulation
Long link designs maintain continuous freedom of movement even when exposed to loose aggregate, wet soil, or light debris. The open profile allows surface dirt to drop away naturally, preventing the stiff jams that often plague tight short-link chains.
Versatile Trade Applications
The 300/Z (3442-219) Bzp 6.5 X 36Mm Long Link Chain is engineered specifically for secondary containment, static tethering, and physical demarcation tasks across commercial and residential premises. Its distinct proportions make it widely specified for the following practical scenarios.
- Perimeter Gates and Field Entrances Wrapping gate frames, paddock timbers, and security posts with standard padlocks.
- Industrial Loading Bays Acting as high-visibility pedestrian walkways, warning curtains, and bay doorway barriers.
- Car Park and Forecourt Controls Demarcating parking rows, cordoning off maintenance zones, and hanging traffic indicators.
- Site Plant and Storage Security Securing ladders, site mixers, timber stocks, and equipment skips against opportunistic movement.
- Agricultural and Marine Tethering General utility lashing, non-overhead tethering, and hanging static signage in dusty or damp outbuildings.
Important Operational Notice
This commercial long link chain is produced strictly for static anchoring, security locking, perimeter demarcation, and general hardware purposes. It is not rated, certified, or tested for overhead lifting, load slinging, crane hoists, or human safety harness suspension. Always consult legal lifting regulations whenever hoisting machinery or heavy materials.

Installation and Maintenance Guidance
Cutting this steel chain down to bespoke project lengths can be achieved swiftly using manual mechanical bolt cutters or an electric disc cutter. When sizing chain runs for swinging barriers, ensure you calculate a slight catenary dip to relieve constant tension on mounting eyeplates and wall anchors.
Although the bright zinc plating offers good resistance against atmospheric weathering, external installations benefit from periodic visual checks. Clean off accumulated road salts, mud, or chemical dust using warm water and a soft brush. Applying a light multi-purpose maintenance oil once or twice each year will ensure the links slide effortlessly and preserve the protective zinc surface for years to come.
