A chemical plant in Rotterdam required a perimeter fence around a flexible storage yard—an area that needed regular access, panel removal, and future change‑out. The client specified zinc‑steel fence panels with alternate screw‑type fixings (screw‑in clamp connectors) instead of welded joints. This allowed swift removal of sections, minimal hot‑works, and maintenance under live plant conditions.
The storage yard operates with occasional vehicle routing changes and panel removals; welded fences were a hindrance. By using zinc‑steel panels plus screw‑type fixings (clamp‑fit connectors) the site achieved modularity and flexibility. Industry guidance on fencing connectors supports use of clamp‑fit connectors enabling on‑site assembly with set screws rather than welding. (Secure Fencing Fixings & Fittings – Jacksons Security)
The system specification covered:
Panels: Carbon steel hot‑dip galvanised per ASTM A123/A123M – Zinc (Hot‑Dip) Coatings on Iron and Steel Products.
Connector system: Clamps and set screws that lock structural tubes without welding—see fencing connector guidance. (Fence Connector Systems – Buisklem)
Finish: Zinc coating to nominal 85 µm, followed by colour powder coat RAL 7016 for industrial aesthetic and high visibility.
Installation: Screws specified stainless grade A4, zinc plated, tamper‑resistant. (Fixings Catalogue – EFC Fencing)
Key design drivers: – **Access flexibility**: Screw connector system meant panels could be removed without cutting or welding, reducing downtime. – **Durability**: Zinc‑steel panels maintained the site’s durability requirements for outdoor industrial exposure. – **Maintainability**: Screws and connectors designed for future removal and replacement reduced lifecycle cost and increased site agility.

The specification referenced:
Acoustical Society of America (ASA) – for structural durability and environmental exposure.
2024 Revision of ASTM A123 – American Galvanizers Association
Following installation:
Panel removal time reduced from 3 hours (welded) to 25 minutes (screw‑connector) during re‑configurations.
No corrosion or coating failure after 15 months in harsh chemical‑site perimeter environment.
Lifecycle maintenance budget reduced by 30% versus prior system with welded joints and mixed coatings.
Site operations reported increased flexibility and reduced maintenance downtime.
These results illustrate the benefit of combining zinc‑steel fence panels with alternate screw‑type fixings in industrial boundary applications.
The strategy succeeded because:
Zinc‑steel panels delivered long‑term external durability in demanding site conditions.
Screw‑type fixings provided modularity, ease of removal and future configuration flexibility.
Installation and future maintenance costs both reduced, improving asset lifecycle.
Standards‑based material and fixing approach ensured specification integrity and performance.
